I'm just a beginner using Ubuntu, so my question might seem a bit dumb. For a task I had to use VMnet3 when I set up my Ubuntu Server, but the way the internet was configured wouldn't let it work.

I had to change my /etc/netplan/50-cloud-init.yaml file to this:

network:
    ethernets:
        ens33:
            dhcp4: false
            addresses:
                - 172.30.0.1/16
            routes:
                - to: default
                via: 172.30.255.254
            nameservers:
                addresses:
                    - 172.30.255.254
    version: 2

When I ping it won't work and says "temporary failure in name resolution". I don't really understand why that all fails because I did exactly what the task said.

Also a problem is: when I want to to do the command ifconfig the command should be installed, but that's not possible because there is no internet connection.

i have HP-LaserJet-M1005 on Ubuntu 24.04 LTS. It is printing single page fine but it doesn't print multiple copies of same page. How do i fix this??

How do we get access to the OEM installation source for an HP Z2 Mini G1i device versus trying to get the normal download to work?

I am new to Linux Mint and I want to know how to lower the speed and duplex of an external Ethernet card.

I want to lower it because the card is installed in a slot that does not provide full voltage. When the card is under heavy use, it turns off and then turns on again.

So I want to reduce the card to the minimum required speed and power.

The card model is SK9521.

Please give easy guides. I only know basic terminal commands, and sometimes I don’t understand what the commands do — I just type them.

Thanks.

everyone.

Problem - I can't start Linux-based PC - I get black screen with blinking cursor.

I used recovery mode and checked the disc - It showed my that C drive is about 450GB and about 420GB was used. Usage was 100%. That's why I assumed that lack of free space on HD is a problem.

I used Live CD and Live USB sticks, opened up problematic drive (let's call it "old") and tried to delete some unimportant files/folders from old HD. They can not be deleted.

Is there a way to delete (or copy) unwanted large files/folders from old HD using the terminal (with Live USB)?

Let me know what can be done. TIA.

I have a dashboard from Home Assistant and would like it to be shown as the desktop wallpaper/background using some web web browser (Firefox, Chromium) in kiosk mode.

How would I tell my Ubuntu 24.04/Wayland/Gnome to automatically start that browser upon user login and run it as desktop wallpaper?

I checked gnome dynamic wallpaper resources and found:

• https://itsfoss.gitlab.io/post/add-dynamic-wallpapers-to-your-gnome-desktop/ only allows to display images
• https://extensions.gnome.org/extension/1040/random-wallpaper/ only allows to display images
• https://github.com/jeffshee/gnome-ext-hanabi only allows to display a video
• https://linuxconfig.org/how-to-create-gnome-dynamic-wallpapers only allows to display images

I remember years before Gnome came up it was possible to start application such that they would run in the root or desktop window - such as xearth, xroach and xsnow used to do.

I accidentally wrote exort instead of export when setting CL_ALL=en_US. What I was trying to do was switch it from Japanese to English, thx ahead!

Here is what I did:

export LANG=en_US.utf8
export LC_ALL=en_US.utf8
echo 'export LANG=en_US.utf8'>>~/.bashrc
echo 'exort LC_ALL=en_US.utf8'>>~/.bashrc
source~/.bashrc
bash: source~/.bashrc: No such file or directory
source ~/.bashrc
bash: 警告: setlocale: LC_ALL: ロケールを変更できません (US.utf8)
exort: command not found
echo 'export LC_ALL=en_US.utf8'>>~/.bashrc
source ~/.bashrc
bash: 警告: setlocale: LC_ALL: ロケールを変更できません (US.utf8)
exort: command not found

How do I fix this?

Welcome :)

I have computer, NUC13 (i5, 64GB ram) with Ubuntu Server 24.04, equipped with two i226-V NICs (one built in, another one is NUC add-on). I observed some network issues, so I tested it with iPerf3. Results are very poor. iperf3 -c x.x.x.x results in speeds around 10-15-30Mbps, while iperf3 -c x.x.x.x -R shows correct transfers (up to 2.5Gbps). It may be worth to add, that UDP test iperf3 -c x.x.x.x -u -b 1000M succeed with 1Gbps. Problem exists on both NICs. I set up iperf binding to specific interfaces to isolate them during test without success. They behave exactly the same.

I already tried disabling eee, changing qdisc, using HWE kernel 6.14 and finally - upgraded Ubuntu to 25.10 with kernel 6.17. Nothing can fix my situation.

Im pretty much sure that networking itself is fine, as I have another machine connected to same switch which don't have any problems with network saturation. Its also not iperf3 issue, because openspeedtest instance shows the same problem.

Please help me. I don't want to lose my data.

One Fine Day..I don't want to shut down my computer, So, “Suspended” it, When turned on next time ,
the problem starts, WiFi – Not Turning ON, Its not a detection problem, or Driver not found or any thing, the whole WiFi option not turning ON, 🥴 ..???

Into Debug Mode,

1. Usual Restart, no result

2. Battery Removed Power off - ON, No result

3. As the "Suspend" Started the problem, trying a chance with several repeated suspends with, plug in and out the USB adaptor(Which is Tp link TL-WN725N), No result,

4. Reset The BIOS to default, On my HP laptop, at booting, it is ESC -> F10 -> F9 -> set to default -> OK, No result,

   Also, BIOS not have any other options for WiFi.

5. Now back to Ubuntu, open the terminal, from internet, understood Ubuntu got a "handy" soft suspending features to turn off connections like the WiFi and Bluetooth, so does a rfkill list all, that shows

   0: phy0: Wireless LAN
       Soft blocked: no
       Hard blocked: yes
   1: hci0: Bluetooth
       Soft blocked: no
       Hard blocked: no
   

   WiFi got hard blocked, but how??, I’m using an HP-15 series laptop with a not working normal keyboard(it is unplugged too), using with an external keyboard.. The WiFi turn on/off keyboard keycode HP gives is Fn key + F12, but as I’m using external keyboard, Fn key not in the picture anymore.. Tried combinations of all f1 to f12 possible...no result..

   There are no other external keys for WiFi.

   Now It started to get seriously annoying, decided to go check in the dual-booted windows, whether it is affected or not, The WiFi works there as usual, with adaptor detecting from the first sight of the windows logo, but in Ubuntu, it behaves like, it never heard about WiFi.

6. Tried sudo rfkill unblock all, sudo rfkill unblock 0 (which is the rfkill assigned code for w LAN) with no results (even-though I know it is “Hard” blocked).

7. Then I get know from the internet some settings or conflicting drivers can be blacklisted in Ubuntu, so do this

   lsmod | grep hp
   
   # The results
   hp_wmi
   hp_wireless
   

   Blacklisting hp_wmi and a reboot solved this issue for some people, they've listed in web, I tried the same, but with no luck.. by going to /etc/modprobe.d/ select blacklist-hp.conf, blacklist.conf added blacklist hp_wmi -> reboot..., but no result same "Hard blocked: yes" also with the blacklist hp_wirelss, no improvements

   same

   0: hci0: Bluetooth
       Soft blocked: no
       Hard blocked: no
   1: phy0: Wireless LAN
       Soft blocked: no
       Hard blocked: yes
   

   After this attempts, the only thing achieved was the numbers changed,now it is 1 for WiFi

8. Where is this Soft blocked, hard blocked get stored, next that will be the concern, if I can find that file and alter the value It will be all good again,

   And Thankfully I founded this, based on the same problem described there, did the

   cat /sys/class/rfkill/rfkill1/hard
   
   # gives me a "1"
   # To make it 0, with all permissions
   sudo -i
   echo 0  >  /sys/class/rfkill/rfkill1/hard
   
   # gives me 
   echo: write error: Input/output error 
   # its fixed by hardware..no way to change
   

   Uninstall and installs the rfkill...(don't know what I'm doing..😵)

9. Now its getting lost, trying to figure out an Ubuntu reinstall or a backed up timeshift can solve the problem, decided to check that, plugged in a bootable USB Ubuntu -> Try before install -> check if the Wifi loads or not., No its also shown as hard blocked :- YES

10. Finally changed the laptop-keyboard only for the sake of getting WiFi back, pressed the key f12 with full confidence which is the hardware key for airplane mode (not only for WiFi)...still no use, that same hard blocked is killing me..

This is where I am now, I badly need this WIFI gets working on ubuntu, can anybody help..

I'm using LightDM as a greeter.

I need to perform a command before the login screen. I've put a file called rotate.conf inside the /etc/lightdm/lightdm.conf.d folder. That file contains a command to rotate the second monitor (it is the only way to have it works properly).

I've tried different rows of code but it seems it doesn't read that instruction.

[SeatDefaults]
command=xrandr --output DP-0 --rotate left

I've tried even without the [...] and command= but without success.

I've also added the last line in user.conf

[UserList]
minimum-uid=500
hidden-users=nobody nobody4 noaccess
hidden-shells=/bin/false /usr/sbin/nologin /sbin/nologin
greeter-setup-script=/etc/lightdm/lightdm.conf.d 

What am I doing wrong?

I have setup Ubuntu 20.04 in Dual boot with Windows 10.

On Windows 10 @ 3840 x 2160 (16:9) resolution I do not have any issues with video, smooth scrolling, IDE, games.

However on Ubuntu @ 3840 x 2160 (16:9) resolution, I get stuttering low FPS for video, jaggy/rough scrolling.

When I set it to 2048 x 1152 (16:9) resolution it is way smoother and no issues.

My hardware info is the following:

Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz
Palit GeForce RTX 2070 8Gb
16Gb DDR3 2400mhz Corsair Vengeance RAM
LG 27inch 4K Monitor

These are the following things I've tried:

• Swapped HDMI to Displayport from GPU to Monitor
• Tried the prorietary Nvidia drivers (version 440), X.org drivers
• Restarting Gnome
• Updating the latest drivers and patches from Ubuntu

I am happy to use the monitor at a lower resolution but I am curious as to what the bottleneck is here?

Is there any fixes?

I have troubles with installing MT4/MT5 under Ubuntu 18.04.2 LTS. I try installing different Wine/Gecko/Mono versions, installing winhttp etc. It always asking me for Proxy server details and the installation is crushing.

I also try changing repositories and any kind of other advise I googled, but still stuck on Proxy request.

Could someone help with advise on the matter? Does MT4/MT5 is supported at all under this Ubuntu release?

Thanks in advance

P.S. Edited: I had been asked to provide specific errors, however after I conduct all suggested solutions listed in the net I don`t get any - it just ask me for a proxy server details, which is a step not needed for MS. From what I found in the net the proxy server details request is the issue itself, it should not happens on the first place.

Briefly I am downloading any of the MT4/MT5 platforms available in the net (from several different brokers), locating them in some folder. Going to that folder by 'cd' command and executing 'wine xxx.exe' command. The program start installing and in one moment it request for proxy server details...

Resolved: If someone has similar problem - check this video - https://www.youtube.com/watch?v=VzgsruDTEuA Download the MT4/MT5 via PlayOnLinux! Then, you could create shortcut for the app - for me it looks like this one:

# !/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Icon[en_US]=gnome-panel-launcher
Exec=~/PlayOnLinux's virtual drives/metatrader4/drive_c/Program Files/MetaTrader$ wine terminal.exe
Name[en_US]=MT5
Name=MT5
Icon=gnome-panel-launcher

Finally it is about amendment of the server, ports etc.

Goodluck and cheers!

I just fresh installed Ubuntu 18.04, after some hassle I was able to install the nvidia-driver-396. I run a dual monitor setup being one a 29" ultra wide and one 24" 1080p, when I had Ubuntu 16.04 the system detected the monitors sizes without a problem, but for some reason on Ubuntu 18.04 the 29" is being detected as 34" and the 24" is being detected as 7", odd thing is that their resolutions are correct it is just the monitor size that is wrong.

VLC for some reason had huge icons on the "detected 7" monitor", I solved that by adding QT_AUTO_SCREEN_SCALE_FACTOR=0 in /etc/environment and /etc/profile.d/gnome-qt.sh

Although that solved the VLC issue the monitors sizes are still being wrongly detected, how can I solve it?

Here are some Screen Shots

This is the 29" monitor:

This is the 24" monitor:

Info on the nvidia driver:

I am trying to resize a fat 32 partition in my linux machine. Following are the specs of the system.

1. This is not a PC hence UI based tools are not applicable.
2. This memory partition which I am trying to resize is already having data in the form of files. I can't lose them.
3. I am trying to shrink the partition to used space alone and move the remaining space to another partition.
4. Preferably without rebooting of system, unmounting of partition would be fine.

Edit: Backing up data from this partition is not what I am looking for. I am trying to see if there is a way that I can try without losing data. Its more like an analysis rather than task.

What I tried till now: Tried using parted tool as gparted needs an UI. Even though I am able to shrink this partition, it is leading to unnecessary problems due to file fragmentation. For example, after shrinking when I run file system check I am getting errors like chain not found for few files.

I cant use tools like resizee2fs as it supports only ext file systems (correct me if I am wrong here).

I tried using tool fatresize, even though I am able to successfully get it install it in my debian I am not able to get an installable for arm, whatever link I am getting is throwing an error on line 1 statement itself.

Can someone help me with any information they could?

I was trying to install UT99 as explained here and here. After downloading libraries I needed, I started to install the program, but later on I got the warning as in subject. I don't understand which is the problem, in other words, the phrase "Locale not supported C library" doesn't explain what is the error.

I try to watch inside my system as:

$ sudo locale -a
C
C.UTF-8
it_IT.utf8
POSIX

Then if type

$ sudo locale -a
LANG=it_IT.utf8
LANGUAGE=
LC_CTYPE="it_IT.utf8"
LC_NUMERIC="it_IT.utf8"
LC_TIME="it_IT.utf8"
LC_COLLATE="it_IT.utf8"
LC_MONETARY="it_IT.utf8"
LC_MESSAGES="it_IT.utf8"
LC_PAPER="it_IT.utf8"
LC_NAME="it_IT.utf8"
LC_ADDRESS="it_IT.utf8"
LC_TELEPHONE="it_IT.utf8"
LC_MEASUREMENT="it_IT.utf8"
LC_IDENTIFICATION="it_IT.utf8"
LC_ALL=

At this point I stopped my installation. Any advice?

Thanks

    =================== Suggested repair
    The default repair of the Boot-Repair utility would purge (in order to fix packages fix executable) and reinstall the grub2 of sda5 into the MBR of sda.
    Additional repair would be performed: unhide-bootmenu-10s


    =================== User settings
    The settings chosen by the user will not act on the boot.

I've got a fairly old desktop (from 2008) with just Ubuntu 14.04 (no dual boot). I haven't booted up this machine in about a year, and I now wanted to start it up again to back up all the pictures that I've got on there, but I seem to be too late. It doesn't boot anymore. When I turn it on I see the following screens appear (in order).

and then it ends with this black screen with just the blinking cursor and nothing happens anymore. I let it in this state for about half an hour, but really nothing happens anymore.

Seeing it says no any drive found in the second screen, I rebooted and pressed Del to enter the BIOS, of which I took two screen photos which I thought could be helpful:

As you can see I've got two hard drives in there. One is the drive on which Ubuntu is installed and the other I used to store all my pictures.

From here I'm kind of lost. Does anybody know what I can do to boot this machine into Ubuntu again?

I have to make my MariaDB authentication a bit safer than default. I tried to set up SSL support for this, but found only an old howto here:

This source was written in 2011. Maybe it is outdated, or I've made a mistake somewhere. When I generated .pems there were no errors. My /var/log/mysql/error.log file is empty.

Do you have any ideas?

I added the following command in crontab -e:

15 * * * * php /home/rizwan/PHP-workspace/mgstore/testcron.php

I need to run testcron.php every 15 minutes; for testing purposes I used the following PHP code in testcron.php:

<?php 
echo "test";

15 * * * * /usr/bin/php /home/rizwan/PHP-workspace/mgstore/testcron.php >> /home/rizwan/cron.out 

this was working .but i have one php script,for adding customers from magento to ERP,when i run script manually,it asks for authorization,after accepting it creates customers into ERP from magento,I need whenever i added customer in magento after 5 or 10 mins this script should run and add the customer to ERP.how this can be done ?,If any one have any idea,please help ?

I want to know how I can restrict user access using OpenSSH Server. Let's say I want

• user 1 to only access /Media, /Documents, and his home folder,
• User 2 should only access /Folder21, and his homefolder,
• User 3 should only have access to /Documents, /Folder21 and his home folder,

How can I do such a thing?

I found how to do it with one folder, but that was for all users, I think? description here: https://bensmann.no/restrict-sftp-users-to-home-folder/

(copied from link I gave above:
Can I just do this:

$ usermod User1 -s /bin/false
$ usermod User2 -s /bin/false

And set the user’s home directory:

$ usermod User1 -d /folder
$ usermod User2 -d /folder

then make all the other folders subfolders of /folder, and restrict access to those folders accordingly to my wishes using the chmod command, or is there a better solution??

Addition and clarification: Adding it to their homedirectory is not an option, as it are shared folders, some users need access to the same content,while it is restricted to other users,

This is what I had in mind:

• user 1
• user 2
• user 3

• user 4

• folder "Network documentation"

• folder "application documentation"
• folder "Downloads"

• folder "Media"

• User 1 needs full access to everything, but Read-only access to application documentation List item

• User 2 needs full access to both documentation folders
• User 3 only needs access to the "Media" folder
• User 4 only needs access to the folder "Downloads" and "Application Documentation"

pthreads works on the system:

$ gcc -o what what.c

However, when I run cmake with the following bare-bones CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.6)
FIND_PACKAGE (Threads)

The output is:

I've tried everything, I've uninstalled and reinstalled, I've tried adding guest additions, nothing is working.

EDIT: I should also add I've been using this guide to getting VB set up: http://alexmk.hubpages.com/hub/How-To-Install-Ubuntu-Steam-TF2-under-VirtualBox-on-Windows-to-get-Linux-Tux-Promo

Could anyone please tell me how to remap my Super (left) key to Ctrl key?

I mean Super (left) should work as Ctrl key.

Is there a command that will list displays connected to the computer?

Specifically, I'm looking to find out how my external monitor is being detected by the system when connected by HDMI cable and what it's (not sure of the correct term here) hardware address is (eg. "CRT-0" or "DFP-1").

This is just a general question, but for reference, I'm using:

• Asus UL30JT laptop - running Ubuntu 12.04 beta and 11.10
• Asus PA238 23" monitor
• HDMI 1.4 cable
• Optimus graphics (Intel + nVidia GeForce 310M) - running with Bumblebee

I have a crontab file that looks like this:

* * * * * /home/abliskovs/update/update.sh

crontab -l outputs the following:

* * * * * /home/abliskovs/update/update.sh
