Can't upload a large table either through PHPMyAdmin or by the terminal https://askubuntu.com/questions/1564119/cant-upload-a-large-table-either-through-phpmyadmin-or-by-the-terminal

My apologies in advance for the length of this message - just wanted to get the fact out there.

My problem is I got an error message (see below) that doesn't make sense (to me). It came about while I was in the process of trying to use the command line to upload a large table into a MySQL database.

I did look at the other threads in this forum with the same error message, but they seemed to not apply to my situation.

I think a little back-story would be helpful here. Initially I downloaded tables from several databases I have online with the aim of recreating them in my new Ubuntu 24.04 Lampp installation on a 1Tb drive. All but one of the databases were successfully downloaded from online and uploaded into MySQL through PHPMyAdmin on my new system. The last database had no problem downloading but gave a "too big" error message when I tried to upload it. Knowing one of the tables was large (90Mb), I split the download into all the tables except the large one, and then just the large one by itself. The small ones uploaded without a problem, but the large one would not go.

The first online remedy was to increase some of the limiting variables in the php.ini file, so I did as follows:

  • upload_max_filesize=150M
  • memory_limit=1024M
  • max_execution_time=120

After restarting the computer the table still wouldn't upload.

The next tip suggested I tried was doing the upload through the terminal. The suggested command was:

sudo mysql -u <username> -p <db name> < <bigfile.sql>

(which I ran from the directory that bigfile.sql was in). When I ran it, I got the following error message:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

After searching through the computer I came to the conclusion that there is no /var/run/mysqld/mysqld.sock as the error message would have me believe. There is an executable named mysqld in the /opt/lampp/sbin directory, but no mysqld.sock in that directory (or any other). However, there is a /opt/lampp/var/mysql/mysql.sock (without the d).

The only file (other than php.ini) I could find anywhere under /opt/lampp/ was a configuration file, /opt/lampp/etc/my.cnf. Checking that file, I found that all reference to "socket" are already equal to the aforementioned /opt/lampp/var/mysql/mysql.sock.

So, I don't know how to find this illusive mysqld.sock, nor what to do next to get this bigfile.sql to upload, and any suggestions would be greatly appreciated.

inverting colors using xrandr screws up font display in Thunderbird and LibreOffice (but not in other apps) - why? https://askubuntu.com/questions/1564117/inverting-colors-using-xrandr-screws-up-font-display-in-thunderbird-and-libreoff

I am on Ubuntu 24.04 LTS.

I am using xrandr's brightness switch to invert the colors on my screens, which makes extended work on my computer much easier on my eyes:

$ xrandr --output eDP --brightness -1.0

This generally works as intended. (I can revert it by setting the brightness to +1.0.)

However, for some reason I don't understand, when I invert the colors on some apps fonts render perfectly (Firefox, gnome-terminal) while in others they get garbled to the point of hardly being legible (Thunderbird, Libreoffice).

Here are two sample pictures, each of them showing the same app without color inversion and with color inversion:

The Thunderbird folder pane:

Two screenshots of Thunderbird without and with colors inverted

Libreoffice Writer (close-up of a word):

Two screenshots of LibreOffice, without and with colors inverted

I thought anti-aliasing and/or hinting might be the problem, so I tried disabling them using dconf-editor. But the problem persists. I also disabled anti-aliasing in Libreoffice's options, but it also produced no improvement.

What is causing this and how can I fix the display of text by Thunderbird and Libreoffice when colors are inverted?

Ubuntu connects to wifi, but has no internet https://askubuntu.com/questions/1564116/ubuntu-connects-to-wifi-but-has-no-internet

I am using RaspAP with default settings on a raspberry pi 5 with raspberry pi os bookworm

the only thing I changed in RaspAP is the name, password and country code, which I set to US (via RaspAP GUI)

I connected my ubuntu machine to it, and it connected perfectly.

I ran a ping google.com, and got no connection.

I pinged 8.8.8.8, and got a perfect connection

My phone connects to it perfectly, reporting no internet access, but when I go to google.com, it loads fine so I don't know what's up with that.

I checked NetworkManager GUI, and it showed DNS was set to auto

please tell me if you need any more info

Ubuntu 24.0 Docker - PHP-FPM + NGINX - PHP-FPM gives /index.php 404 error https://askubuntu.com/questions/1564115/ubuntu-24-0-docker-php-fpm-nginx-php-fpm-gives-index-php-404-error

I have a docker setup with Laravel Application that works fine on local Mac however, I am facing issues with the deployment on Ubuntu server 24.0.

  1. All my paths are correct

  2. All my volumes are mapped correctly

  3. I checked the file location which exists

  4. I have correctly pointed the root for NGINX i.e. both the NGINX and PHP-FPM has the same folder structure /var/www/api/public

  5. User & Group ID matches the host OS i.e. 1000:1000 in all containers

  6. Permissions:

    1. api: 755

    2. api/storage : 775

    3. api/bootstrap/cache: 775

Where could be the issue?

I have created a git repo for this setup here. The folder structure I have is:

Project Folder
|- docker-laravel
|- api

The log after running docker compose -f docker-compose.yml -f docker-compose.prod.yml logs php

Log of php-fpm container

EDIT after command

docker exec -it $(docker container ls --filter=ancestor=nginx:alpine -q) find /var/www | grep public/index.php

User id requirments https://askubuntu.com/questions/1564108/user-id-requirments

I am trying to find out what the user id requirements are for a new user. I am on 24.04.4 LTS, using user add command. What are the requirements for a new user id? I know it can't be more than 8 characters, but are there any other requirements? I suspect we are entering an invalid user id, but without knowing what the requirements are I don't know what part of the user id is not valid.

Thank you

Wifi continuosly disconnects in Ubuntu 25.10 https://askubuntu.com/questions/1564091/wifi-continuosly-disconnects-in-ubuntu-25-10

I am incredibly new to Ubuntu so I know next to nothing about how it works. My issue is that after having my computer on for a bit the Wifi stops working and will will not connect to any other Wifi until after I restart my computer I have attempted to look online to try to find drivers but found nothing that works. I don't know what to do to fix this issue.

grub does not see the Windows 10 disk/partition https://askubuntu.com/questions/1564083/grub-does-not-see-the-windows-10-disk-partition

I did see many posts regarding this topic, but none helped me to solve it.

I had an older PC with dual boot Ubuntu and Windows 7 running. both on different disks.

I moved the Ubuntu disk to another PC running Windows 10.
Starting Windows 10 worked as usual, but not Ubuntu, so I used Boot-Repair. On the first run Boot–Repair went through (including removing/installing grub) using the default settings. After restarting there was no grub on any disk (there are 4 internal disks and 2 USB disks with data and for backup). Running disk repair again, trying to define which disk should contain grub and also trying to use the default repair now always gave the following error message:

The current session is in BIOS-compatibility mode. 
Please disable BIOS-compatibility/CSM/Legacy mode in your UEFI firmware, 
and use this software from a live-CD (or live-USB) 
that is compatible with UEFI booting mode. 
For example, use a live-USB of Boot-Repair-Disk-64bit   
(www.sourceforge.net/p/boot-repair-cd), 
after making sure your BIOS is set up to boot USB in EFI mode.

Only BIOS is set to UEFI and I could not find the BIOS-compatibility settings.

Based on some thread in this forum I did the following:

  • mount /dev/sda5 /mnt

  • Then run the following to do a chroot to reinstall grub on the system:

  • for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done

  • chroot /mnt

    The later 2 steps threw an error message, /cow etc. I solved it by sudo apt-get install grub. It seems the Boot–Repair did not install grub properly.

    Then you should be at a $ prompt and see your Ubuntu installation. You should now be able to reinstall grub and update grub.

  • sudo grub-install /dev/sda

  • sudo update-grub

Only the Windows on disk /dev/sdh was not found

Searching through several threads did not solve it.

What I did:

  • turned off Fast Boot and Windows power setting: no effect (still left it that way)

  • trying 40_custom settings using the hd8,1 (for /dev/sdh) did get

    grub cannot get C/H/S values

  • I tried several hdX settings, but none worked.

Next based on another thread:

menuentry "Windows 10" --class windows --class os {
   insmod ntfs
   search --no-floppy --set=root --fs-uuid 6A4C90714C9039B1
   ntldr /bootmgr
}

The uuid is the ntfs partition (/dev/sdh2), I also tried the efi partition uuid (/dev/sdh1)
This had no effect. Windows does not boot from the grub boot menu.

Do you have any other suggestions to get Windows to start from the grub boot menu?

How can I fix boot problem (ending up in BusyBox, UUID not found) https://askubuntu.com/questions/1563923/how-can-i-fix-boot-problem-ending-up-in-busybox-uuid-not-found

I have a dual boot setup (Windows and Ubuntu) on my computer. For background, a while ago when I had different Ubuntu issues I already disabled Windows' "Fast Startup".

The current issue: I tried one day to boot into Ubuntu 24.04, and I just got a screen with the following text:

BusyBox v1.36.1 (Ubuntu 1:1.36.1-6ubuntu3.1) built-in shell (ash) Enter 'help' for a list of built-in commands.
(initramfs)

If I enter "exit" I get:

BusyBox v1.36.1 (Ubuntu 1:1.36.1-6ubuntu3.1) built-in shell (ash) Enter 'help' for a list of built-in commands.
(initramfs) exit
Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=1785c362-92ff-4a9a-b254-f950db82ad8c does not exist. Dropping to a shell!
BusyBox v1.36.1 (Ubuntu 1:1.36.1-6ubuntu3.1) built-in shell (ash)
Enter 'help' for a list of built-in commands.
(initramfs)

My next step was a long, long foray trying to get Perplexity to help me fix the problem. I will summarize for you anything that may be illuminating from those attempts.

It had me create a removable drive to boot Ubuntu temporarily from, and get to the Terminal. At one point, it had me run the following for "quick diagnostics":

sudo blkid | grep nvme0n1p7
cat /mnt/root/etc/fstab | grep nvme0n1p7
sudo mount /dev/nvme0n1p7 /mnt/root
journalctl -xb | grep -i "nvme0n1p7\|1785c362\|fsck\|mount"

The output was very long, so I'll give you Perplexity's evaluation of the output:

Key findings from your output​

✅ UUID perfect: /dev/nvme0n1p7 has correct UUID 1785c362-92ff-4a9a-b254-f950db82ad8c
✅ Filesystem mounts fine: Kernel successfully mounted it read-only earlier
❌ Mount point missing: You ran cat and mount without creating /mnt/root first
❌ No /etc/fstab access: Because /mnt/root wasn't mounted when you checked
⚠️ os-prober found your Ubuntu: 40lsb detected /dev/nvme0n1p7:Ubuntu 24.04.3 LTS

A couple more failed fixes/boots back to the BusyBox later, it had me do more diagnostics. Here is the output from that:

ubuntu@ubuntu:~$ # 1. Test if root mounts read-write now
sudo mkdir -p /mnt/test
sudo mount /dev/nvme0n1p7 /mnt/test
mount | grep nvme0n1p7
sudo umount /mnt/test

# 2. Check filesystem health
sudo fsck -n /dev/nvme0n1p7

# 3. Verify GRUB kernel line
sudo mount /dev/nvme0n1p7 /mnt/root
grep "root=" /mnt/root/boot/grub/grub.cfg

# 4. Boot parameter check
sudo mount /dev/nvme0n1p1 /mnt/efi
ls -la /mnt/efi/EFI/ubuntu/
/dev/nvme0n1p7 on /mnt/test type ext4 (rw,relatime)
fsck from util-linux 2.39.3

       dmesg(1) may have more information after failed mount system call.
grep: /mnt/root/boot/grub/grub.cfg: No such file or directory
mount: /mnt/efi: mount point does not exist.
       dmesg(1) may have more information after failed mount system call.
ls: cannot access '/mnt/efi/EFI/ubuntu/': No such file or directory

...to which it said:

Key takeaways from output

✅ /dev/nvme0n1p7 mounts read-write perfectly (rw,relatime)
✅ Filesystem clean (no fsck errors)
❌ Missing /mnt/root, /mnt/efi directories
❌ No /mnt/efi/EFI/ubuntu/ = GRUB EFI files missing (main problem!)

I ran its next code to "Fix the mount directory issues + reinstall GRUB EFI". Output:

ubuntu@ubuntu:~$ # Create missing directories
sudo mkdir -p /mnt/root /mnt/efi

# Remount with proper structure
sudo mount /dev/nvme0n1p7 /mnt/root
sudo mount /dev/nvme0n1p1 /mnt/efi

# Verify GRUB files NOW exist
ls -la /mnt/efi/EFI/ubuntu/
grep "root=" /mnt/root/boot/grub/grub.cfg

-rwxr-xr-x 1 root root     108 Jan 31 16:05 BOOTX64.CSV
-rwxr-xr-x 1 root root     117 Jan 31 16:05 grub.cfg

-rwxr-xr-x 1 root root  966664 Jan 31 16:05 shimx64.efi
grep: /mnt/root/boot/grub/grub.cfg: Permission denied

...to which it said "Excellent—GRUB EFI files are present and recent (Jan 31 timestamps), but Permission denied on grub.cfg needs fixing."

So I ran its next code for "Quick permission fix + final verification". Output:

ubuntu@ubuntu:~$ # Fix grub.cfg permission (live USB -> root filesystem mismatch)
sudo mount -o remount,remount,rw /mnt/root
sudo chmod 644 /mnt/root/boot/grub/grub.cfg

...to which it responded: "PERFECT—your GRUB config is 100% correct. Every root=UUID=1785c362-92ff-4a9a-b254-f950db82ad8c matches your fstab exactly.​

GRUB hands the kernel the right parameters. The problem is initramfs itself failing to mount root."

It then sent me down this wasted rabbithole of "Since everything else checks out, increase initramfs root delay + force regeneration".

If anyone can help me where the AI could not, I would be very appreciative. Of course I will give any other information you may need.

Configure all keys of "ThinkPad TrackPoint Keyboard II" on Ubuntu https://askubuntu.com/questions/1563493/configure-all-keys-of-thinkpad-trackpoint-keyboard-ii-on-ubuntu

I am using the great external keyboard "ThinkPad TrackPoint Keyboard II" (AZERTY layout) with Ubuntu. On recent versions the keyboard is quite well recognized. But I would like every key to work. For example the Fn functions work : Fn+F1 mute, Fn+F2 volume down, etc. But some basic keys don't work like for example :

  • next to backspace, on the right, the key with - and _ displays "=" when pressed.

  • the key !8, when pressed displays "_" instead of "!"

  • the key "+=~" on the lower right, displays "!"

  • and several others.

Do you know how to configure the keyboard properly on a recent Ubuntu 24.04?

Do you know how to configure the keyboard properly on an old Ubuntu 16.04?

I can configure every key manually if needed, but I don't know how.

Thank you

Add an image on top of a PDF page https://askubuntu.com/questions/1562930/add-an-image-on-top-of-a-pdf-page

I often find myself signing PDF files I receive via email, which I have to print, sign by hand, and scan. It's a huge waste of time and frustrating. I already have a PNG image of my signature, and I'm convinced a simple tool that overlays the image onto the PDF file I need to sign would be enough. There are some rather dated (13-year-old) solutions online, some geeky (using Ghostscript) or software from external repositories, or LibreOffice, which however alters the PDF upon import. We're now on Ubuntu 24. Is there any software that can easily overlay an image onto a PDF page without using scripts or dubious apps? Thanks.

Importing OpenVPN from TP-Link Router https://askubuntu.com/questions/1554296/importing-openvpn-from-tp-link-router

I am using TP-Link's built-in OpenVPN server. It is as simple as setting the port, subnet, and netmask. The VPN works great using the OpenVPN client on my Windows computers and my Andriod phones, but I have not been able to sucessfully use is on my Ubuntu box.

I'm using a fresh 24.04 and the GUI to import a VPN connection. I import the ovpn file, it creates a ca.pem, cert.pem, and a key.pem.

When I try to conect to the VPN it just times out. I don't see a log in /var/logs/openvpn

Any help would be great. Here is the ovpn file that my TP-link router generates:

NVIDIA drivers are not recognized in Ubuntu 22.04 (they are shown, they are not used) https://askubuntu.com/questions/1468217/nvidia-drivers-are-not-recognized-in-ubuntu-22-04-they-are-shown-they-are-not

Premise

I tried pretty much everything I could find, I will list the attempts below.

Question structured as follows: Premise, Problem, Question, Attempts.

My PC:

  • Gigabyte X570 I AORUS PRO WIFI Mini ITX AM4
  • AMD Ryzen 5 5600x (Zen3)
  • Palit Dual GeForce RTX 3060Ti 8GB
  • MX500 1TB (Ubuntu)
  • Sabrent Rocket 4.0 500GB (Windows)
  • MX500 2TB (storage)

Also:

  • Secure Boot is disabled (also CSM is disabled)

Objective

Ubuntu 22.04 LTS Installation for Machine Learning development, mainly GPU accelerated:

  1. CUDA is needed
  2. Nouveau drivers are not optimal, hence they are currently blacklisted
  3. NVIDIA drivers are needed
blacklist nouveau
options nouveau modeset=0

Problem

The driver is recognized as:

  • It is shown in the Software & Updates as installed

Software & Updates Screenshot link

But it is clearly not used as I'm writing this in 1024x768 (4:3).

Taking a look at drivers/what is recognized:

Ignoring this means installing the drivers specifying the version, so with:

sudo apt install nvidia-driver-530-open

It does its thing, then trying nvidia-smi, output:

No devices were found

Is the kernel module loaded? Seems like it is:

teniu@AW-PC:~$ lsmod | grep nvidia
nvidia_uvm           1441792  0
nvidia_drm             77824  1

drm                   581632  5 drm_kms_helper,nvidia,nvidia_drm

Trying again to see if nvidia is seen:

lspci | grep -i nvidia

teniu@AW-PC:~$ lspci | grep -i nvidia
09:00.0 VGA compatible controller: NVIDIA Corporation GA104 [GeForce RTX 3060 Ti] (rev a1)
09:00.1 Audio device: NVIDIA Corporation GA104 High Definition Audio Controller (rev a1)

Seems like it.

Question & Recap

nvidia-smi

Doesn't work, but the drivers are seen? I am clueless now.

The Ubuntu 22.04 LTS used for this is a fresh install.

What I think can be a major hint is this output, since NVIDIA modules are not found in the kernel modules directory.

teniu@AW-PC:~$ modinfo $(modprobe --resolve-alias nvidia)
modprobe: FATAL: Module nvidia not found in directory /lib/modules/5.19.0-41-generic
modinfo: ERROR: missing module or filename.
  • What am I supposed to do now?

Attempts (all failed)

  • Purge and reinstall (multiple)
  • Changing to 515 drivers instead of 530 (twice)
  • (did I install the wrong version...?)
  • Disabling Secure Boot (and try again everything)
  • Fresh Ubuntu install
  • Test on Windows (it works there, no hardware problems)
  • Headers update, 0 updates
sudo apt install linux-headers-$(uname -r)
  • (I would like to avoid manual installation through download)
  • Give up (not an option)

Useful but unrelated information

When I built the PC I had to update the BIOS since the motherboard didn't offer native support for the Zen3 architecture of the Ryzen 5 series.

I mention this only because at startup, I see the fast terminal gibberish and at the top there is written something about the AMD not being recognized. Although I highly doubt it is somehow related or of importance, since it works afterwards.

Terraform + Cloud-Init via extra_config & DataSourceVMware https://askubuntu.com/questions/1366315/terraform-cloud-init-via-extra-config-datasourcevmware

Question:

Has anyone successfully used terraform + extra_config + Ubuntu cloud images to interface with Cloud Init, providing metadata/userdata? I'm hoping this will interact with DataSourceVMware, but can't be sure at this stage.

What I've been doing:

I am using Terraform to deploy Ubuntu cloud images on VMware vSphere 7. It's been easy enough to use vApp Properties:

... below code snipped from resource "vsphere_virtual_machine" "vm" { }

vapp {
    properties = {
        hostname = var.vm_Name_Lower
        instance-id = var.vm_Name_Lower
        user-data = base64encode(file("${path.module}/userdata.yml"))
    }
}

But any attempt to use extra_config has failed. I would like to be able to supply both guestinfo.metadata and guestinfo.userdata. But currently, my tests with metadata (seen below) have appeared to fail as the hostname is not set in the VM:

data "cloudinit_config" "metadata" {
    gzip = true
    base64_encode = true
    part {
        content_type = "text/cloud-config"
        content = <<-EOF
            local-hostname: testvm
            instance-id: testvm
        EOF
    }
}

... below code snipped from resource "vsphere_virtual_machine" "vm" { }

extra_config = {
    "guestinfo.metadata" = data.cloudinit_config.metadata.rendered
    "guestinfo.metadata.encoding" = "gzip+base64"
}

I can see the vSphere log entry to prove that the extra_config was sent:

config.extraConfig("guestinfo.metadata"): (key = "guestinfo.metadata", value = "H4sIAAAAAAAA/2SOTUvGMBCE74H8h/De11dPQsSDHz14qIK ... snipped

why pip is not installed but after creating new venv and activating it, pip does work? https://askubuntu.com/questions/1277091/why-pip-is-not-installed-but-after-creating-new-venv-and-activating-it-pip-does

I'm confused by venv in linux. I have a fresh ubuntu 20.04 installed. when I entered python in terminal it says command python is not found and the same for pip, but python3 works (still not for pip or pip3). I created a venv using python3 -m venv new_env and python command works there and its version is 3 but this time pip runs with no problem. My question is why this happens and how to make python command runs python3 in main environment as well. Is it related to environment variables and PATH and causes problem when working with different venvs?

Can't switch to Nvidia graphics card because the kernel driver is not in use https://askubuntu.com/questions/1218225/cant-switch-to-nvidia-graphics-card-because-the-kernel-driver-is-not-in-use

I tried several times to switch to my Nvidia graphics card on Ubuntu 18.04.4, however it does not seem to work. After some research I found out that the kernel modules are available, but the kernel drivers are not in use.

Strange characters displayed after awakening from regular sleep in Ubuntu 18.04 https://askubuntu.com/questions/1100074/strange-characters-displayed-after-awakening-from-regular-sleep-in-ubuntu-18-04

After awakening from a regular sleep in Ubuntu 18.04, I often notice strange characters bugs in the Gnome interface. I link screenshots to this post. The only way I found to fix it is to perform a reboot.

It happens to me with French and English interfaces, and it happened with 2 different Ubuntu 18.04 installations on my computer.

I though this issues may be related to How to fix missing characters from font after awakening from suspend?, still none of the proposed solutions worked for me, and my characters didn't disappeared, but changed.

I guess it may be related to interference between my NVidia card (840M), the Intel Display HD card, and Gnome...

I am using NVidia additional drivers : GM108M (Geforce 840M) nvidia-driver-390 (proprietary, tested), on an Asus computer - UX303ln.

Application launcher characters bug:

I faced a new issue : after going to sleep mode, my computer wasn't able to recover from the dark screen.

I even tried ALT+SYST+[R, E, I, S, U, B] to reboot the computer, without success. I had to hard reboot by holding the power switch. One week ago, a similar problem caused my SSD to be corrupted. I had to buy a new one and that's why I could say I tried two different Ubuntu installation. Maybe this is linked to the data corruption issue with the new Linux version? https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.19.8-Released

By looking more specifically for this dark screen problem here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1774950 , I discovered the "nouveau" driver issue concerning nVidia graphics cards. Two possibilities are proposed : downgrade the Linux Kernel to 4.14 or disable nouveau through GRUB. I have chosen the second option for now. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1774950/comments/24

Set

nouveau.modeset=0

to GRUB_CMDLINE_LINUX in the /etc/default/grub file, after that run:

sudo update-grub
sudo reboot

I will answer this issue in a few days if I found out the problem not to occur anymore.

Cheers.

Visual Studio Code doesn't start anymore https://askubuntu.com/questions/1074522/visual-studio-code-doesnt-start-anymore

I'm completely new to Linux and wanted to experiment a little, so I don't really know what I'm doing. I am on working Ubuntu 18.04 and I have been unable to get Visual Studio Code to start again, even though it was working before. Trying to launch it through the application menu only resulted in a short loading animation followed by nothing. Launching it through the terminal issued /usr/lib/snapd/snap-confine: error while loading shared libraries: libudev.so.1: failed to map segment from shared object. I already tried to reinstall it. But attempting it through the terminal somehow didn't work at all manuel@Manuel-Ubuntu:~$ sudo dpkg --remove visual-studio-code dpkg: warning: ignoring request to remove visual-studio-code which isn't installed. According to the Ubuntu Software center it was installed.

I tried the suggestion by @karel snap-confine refuses to launch application to avoid permission attack, which didn't help my problem.

How to disable autorefresh in snap https://askubuntu.com/questions/930593/how-to-disable-autorefresh-in-snap

Is it possible to disable autorefresh in snap? This link says that Snaps are updated automatically in the background to the latest version, every day. Some snaps (e.g. vlc) are built daily, and it makes no sense to install them every day.

Second screen resolution Nvidia graphics in Ubuntu 14.04 https://askubuntu.com/questions/664012/second-screen-resolution-nvidia-graphics-in-ubuntu-14-04

After Ubuntu 16.04 release I am having more problems with the second screen. The solution below I wrote before doesn't work. It has worked for Ubuntu 14.04.

I am new to Linux. This is my third format in 3 months.

I have 2 screen with same resolutions. Both 1920x1080. Nvidia GPU drivers from X.org server.

The first screen resolution is OK. The second screen resolution is not going higher than 1024 like this code block from my system.

I have two OSs and the Ethernet lights on my computer don't turn on when the cable connected and I cannot connect to the internet. This is not a hardware problem, since my second OS connects to internet easily.

I'm also try static IP address but still have the problem. Please help me, I really do not have any other idea!

UPDATE

When I run ifup eth0, the syslog output is:

So I tried Linux kernel version 14 and 18, but both have same problem. Any idea?

UPDATE 2

I tried to use a static IP address, so I changed interfaces:

auto lo
iface lo inet loopback

auto dsl-provider
iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth1 up # line maintained by pppoeconf
dns-nameservers 8.8.8.8 8.8.4.4

UPDATE 3

My laptop has a problem, so I connect the laptop to a PC (rather than laptop to ADSL modem) and for now every thing is OK. But how can I connect laptop to ADSL modem?

This problem is related to Ubuntu because I checked several time on Windows 8 and I have no problem.

I reset ADSL modem router but still have the same problem.

UPDATE 4

I can detect Ethernet for once and everything was OK, but when I restart still have the same problem. There should be a command to fix this issue.

Nvidia 740M still not working after Bumblebee installation https://askubuntu.com/questions/366580/nvidia-740m-still-not-working-after-bumblebee-installation

First of all, I have checked a lot of similar topics, but I still can't get my laptop to use Nvidia 740M.

So first things first.
I have a laptop Asus X550V (i5-3230, 4gb RAM, Nvidia 740M + Intel HD4000). I installed Ubuntu 13.10 alongside Win8 (preinstalled) and both systems are running without problems. However, I have a problem with second graphics card (Nvidia 740M), as Ubuntu doesn't recognize it. I installed bumblebee with this tutorial, but I still get an error

Cannot access secondary GPU" error when trying to run ''optirun Steam'' in terminal.

Then I tried to do this:

[ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected. you need to edit the /etc/bumblebee/xorg.conf.nvidia (or /etc/bumblebee/xorg.conf.nouveau if using the noveau driver) and specify the correct BusID by following the instructions therein.

But with lspci / VGA I get only info about Intel 4000, but no Nvidia. When I type only lspci, I get the line for Nvidia 740M, but after I edit the config file I still get second card error.

Also, in /etc/bumblebee/xorg.conf.nvidia there wasn't BusID or anything similar, so I just added the whole line in device section.

As I said, I tried a lot of things to get it working, avoiding this forum (as I didn't want to bother people with some solutions possible), but alas!, I had to bother you.

If there is a need for some additional info, just say, no problem at all.

Thank you very much in advance. :)

Do I need to set a "location" for a printer in Ubuntu? https://askubuntu.com/questions/258745/do-i-need-to-set-a-location-for-a-printer-in-ubuntu

I am trying to install the printer onto my ubuntu system and after having installed the driver, it simply wont install. It shows me the actual printer, but I click print and nothing happens. Everything is filled out in the printer properties, but the "location" field. Is that where the printer's IP address goes?

How can I add text and images (for example, a signature) to a PDF? https://askubuntu.com/questions/87419/how-can-i-add-text-and-images-for-example-a-signature-to-a-pdf

On occasion I receive forms to fill in as PDFs intended for printing (these are not true PDF forms, they do not contain fields). I would like to type onto them, and perhaps add a scanned copy of my signature. This way I could just email them back. Is this possible?

How to align twinview monitors with different resolutions and prevent mouse disappearing into dead areas? https://askubuntu.com/questions/48922/how-to-align-twinview-monitors-with-different-resolutions-and-prevent-mouse-disa

I'm using two monitors of different brands and resolutions with NVIDIA TwinView, which works well enough, but one thing that's getting to me is how the mouse can move off the edge of the visible screen space below the left-hand screen and above the right-hand screen (see screenshot).

<img src="https://i.sstatic.net/3RHnb.png"

It makes it much more difficult to hit buttons at the bottom/top of each screen, since the cursor just disappears off the edge. Is there a way of changing this behavior?
