I had installed Google Earth with the help of AI because it was asking for some library packages which has a different naming on 25.10 and they were not recognized by the app. After some trial and error sesion, I was able to run it few times but today it is not launching. Nothing happens when I clicked the icon on Apps and I get "command not found" for google-earth-pro command on terminal. However, if I run google-earth-pro --version this command is launching the app. How do I fix this?

I have ubuntu 24.04.3 installed

Suddenly there's Klipper (KDE), KWalletmanager (KDE), Discover (a gui for a KDE packet manager) and a monitoring tool which I already have installed. When I click on properties I see that monitoring tool in the snap package manager. So now I have two instances of the same monitor? How come KDE apps appear in my gnome desktop?

I cannot get rid of Klipper. When I run 'sudo apt remove klipper' the system says it cannot find the packages. It is not to be found in the snap gui package manager, not in 'discover' the KDE packet manager either.

I go to /var/log/apt and print tail -50 history.log and I see the following:

This is so totally weird, I don't remember doing this. it feels like someone is messing with my system, am I paranoid ? Even my spinning wheel has changed shape (the wheel that spins when you're waiting for something to complete).

I have set all updates to be downloaded executed automatically and I have Ubuntu Pro with all options opened. Is that the explanation? I get upgrade notifications for LTS versions only.

Can anyone explain what has happened?

Thank you.

Ubuntu 24.04.3 LTS

I've been having difficulty with static since swapping from windows to ubuntu.

I think I have found a solution in an answer to another question, but I'm not an experienced enough user to follow the steps outlined.

Specifically I'm having three issues:

• Firstly, I don't have permissions to modify the directory (/etc/pulse) as I believe it belongs to root.
• Secondly, the answer specifies a file called 'default.pa' and my file is called 'default.pa.save' though the answer is a number of years old so this could simply be something that has changed over time.
• Thirdly I don't have an application that can open 'default.pa.save' to make the necessary modifications.

I'd be grateful as anyone who could help or even just point me in the directions of resources that would teach me to do this.

This is the other question if curious: Crackling/static in Discord with default audio output port (PulseAudio)

Мои наушники Huawei FreeBuds Pro 3 либо не подключаются к ПК, либо не подключаются как устройства вывода, я так решил, потому что в настройках звука в списке нет моего устройства.

After upgrading my persistent live USB system to Ubuntu 24.04, I found the welcome screen/installer popped up every time I logged in. I wanted to disable it. I found several published methods for stopping this which DIDN'T WORK FOR ME. These methods involved removing or curtailing the activity of one or more of the following packages

• ubiquity

• subiquity

• gnome-initial-setup

This UbuntuHandbook link provides a snapshot of those methods.

I wrote a short script that runs whenever my server restarts, however, the client tmux session is active after the server boots, but the api tmux session is not.

I'm using the following script

#!/bin/bash
#
#
# Start api
tmux new -s api -d 'cd ~/maconet-portal && source venv/bin/activate && cd RoffelBackendPOC && uvicorn app.main:app --host 0.0.0.0 --port 8000' &

# Start client
tmux new -s client -d 'cd ~/maconet-portal/roffel-portal && sudo serve -s build -l 80' &

As far as I understand it this should first start a new tmux session which eventually runs uvicorn to boot up the api, and also create a new tmux session for the client and serve it.

Running the script manually correctly boots both tmux sessions

Is there something I'm missing?

Comfast CF-922AX mt7612U/UN USB3 dongle is not working in Ubuntu 24.04.3 (6.14.0-37 kernel).

Is where any way to fix?

Same adapter works in W10 21H2 without any problems at the same port. Realtek RT8812 dongle works without any trouble as well both in Ubuntu and W10 on the same USB port.

It's could be significant, that this adapter is 'Zero driver' which means it identifies as USB CD-Rom device (idVendor=0e8d, idProduct=2870) with windows driver installer executable and as network adapter (idVendor=0e8d, idProduct=7612) after CD-ROM eject command or some kind of reinsertion (like connecting to VM) without power off or some reset action.

When going into suspend/hibernation I had the problem that my usb driver blocked these actions, so I used the following script

#!/bin/sh
# Disable Intel Comet Lake xHCI before suspend/hibernate
# and re-enable it after resume

XHCI_DEV="0000:00:14.0"
XHCI_DRIVER="/sys/bus/pci/drivers/xhci_hcd"

case "$1" in
   pre)
       # Unbind xHCI -> cuts power to USB 1/2/3
       if [ -e "/sys/bus/pci/devices/$XHCI_DEV/driver/unbind" ]; then
           echo "$XHCI_DEV" > /sys/bus/pci/devices/$XHCI_DEV/driver/unbind 2>/dev/null || true
       fi
       ;;
   post)
       # Rebind xHCI after resume
       if [ -e "$XHCI_DRIVER/bind" ]; then
           echo "$XHCI_DEV" > "$XHCI_DRIVER/bind" 2>/dev/null || true
       fi
       ;;
esac

exit 0

This worked for suspend and got it to go to s2idle. However deep sleep still gave me issues and I want to go into hibernation anyway. When going into hibernation and starting up again, nothing was saved and the logs showed:

Does anyone know how to fix this?

P.S. I have a Lenovo Ideapad s540 13IML, and I can’t cut power to the broken usb port from the BIOS. But, the broken USB also doesn't list in ubuntu.

Problem

I recently installed Ubuntu 24.04.2 LTS on my Infinix X2 Slim laptop. Everything works fine except for no audio from the built-in laptop speakers. Headphones work (in some cases), but the laptop speakers are completely silent. What I’ve Tried

I’ve tried the following methods but none have worked:

✅ Checked alsamixer (unmuted everything)

✅ Tried switching between PulseAudio, ALSA, PipeWire, and WirePlumber

✅ Installed and configured pavucontrol

✅ Reinstalled sound-related packages:

I recently installed Ubuntu 24.04 LTS on my physical machine and successfully logged into the system. However, I am experiencing a strange issue with my keyboard, and I need help troubleshooting it.

Problem Details:

Initially, the keyboard worked perfectly after the installation. After some time of usage, the keyboard suddenly stopped responding completely. None of the keys seemed to register any input. While troubleshooting, I started pressing random keys on the keyboard, and I noticed that:

• Some keys eventually registered in a text editor or terminal, but it was extremely slow.
• The input was intermittent and random — not all keys were recorded, and there was a noticeable delay in response time.

Troubleshooting Steps I Have Tried So Far:

• I checked whether the keyboard was physically connected properly (USB port in this case) and even tried using different USB ports.
• I tested the keyboard on another machine, and it works without any issues, so the hardware seems fine.
• I restarted the machine, but the issue persists.
• I tried plugging in another external keyboard, but it showed the same behavior.
• I verified that the issue is not related to Num Lock or keyboard layout settings in the OS.

Environment Details:

• OS: Ubuntu 24.04 LTS (64-bit) installed on a physical machine
• Keyboard: USB wired keyboard

Additional Observations:

• The keyboard issue seems to occur randomly and not immediately after booting the machine.
• Mouse input and other peripherals are functioning normally.

Questions:

• Has anyone faced a similar issue with Ubuntu 24.04 LTS or other versions?
• Could this be related to a software bug, driver issue, or some background process interfering with the keyboard input?
• Are there specific log files I should check to diagnose this issue (e.g., system logs or kernel logs)?
• Would updating the kernel or reinstalling Ubuntu help, or is there a workaround to fix this without reinstalling?
• Are there any specific packages or drivers I need to install to ensure proper keyboard functionality?

I would greatly appreciate any guidance or suggestions to resolve this problem.

Thank you in advance!

I have tried the solution from this thread: How to upgrade VirtualBox 6.1.38 to 7.0 on Ubuntu 22.04? but for me I couldn't proceed further after first step: E: Sub-process /usr/bin/dpkg returned an error code (1).

I’m facing an issue with my dual-boot setup of Ubuntu 22.04 and Windows on a Dell Inspiron 15-3567. The system has been working fine until recently when I noticed that Ubuntu fails to boot with kernel 6.8.0-45-generic. It gets stuck on a blank screen and eventually throws the following error: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) CPU: 1 PID: 1 comm: swapper/0 not tainted 6.8.0-45-generic #45-Ubuntu Hardware name: Dell Inc. Inspiron 15-3567/04YVDP, BIOS 2.9.0 01/17/2019

What I’ve tried so far: Updating GRUB using sudo update-grub after booting into 6.8.0-40-generic — No change.

Reinstalling the problematic kernel (6.8.0-45-generic) throws an error: E: Internal Error, No file name for linux-image-6.8.0-45-generic: amd64.

Attempting to remove the kernel using both apt and dpkg --purge results in dependency problems. When I try to fix it using: Additional Info: The kernel panic error specifically occurs with 6.8.0-45-generic. Booting into 6.8.0-40-generic works without any issues. I’ve tried cleaning up old packages and running sudo apt autoremove, but the problem persists. I would appreciate any suggestions for fixing this issue or removing the problematic kernel cleanly. Is there a way to forcefully purge the kernel without breaking the system?

I've tried this twice with the Ubuntu 24.04 ISO, written with dd and the Startup Disk Creator app to a thumb drive.

When I used dd, I used the following command:

sudo dd if=ubuntu.iso of=/dev/sda bs=1M status=progress

I booted the Ubuntu 24.04 ISO from a thumb drive, on a late 2023 ThinkPad X1. I got the normal boot menu, and selected the default. I typed Esc to get to the messages, and as you can see, it got stuck for an hour trying to work through.

Job ldconfig.service/start running

for over an hour (I was in a meeting) and nothing more happened.

I just tried it again on a KVM virtual machine, and I get a similar result (though I'm not sure how to verify the boot messages on KVM).

I've since also successfully installed Linux Mint and Oracle Linux, based on the same instructions, on the same ThinkPad X1 using the same dd command.

For other reasons, I'd prefer Ubuntu, but I may have to settle for one of the other Linux distros.

I've also verified the signature:

sha256sum -c SHA256SUMS 2>&1 | grep OK
ubuntu-24.04-desktop-amd64.iso: OK

I've gotten suggestions to try Why Doesn't a Bootable USB Boot, and that has not helped. Thank you for the suggestion.

My solution: I installed Kubuntu 24.04. Thanks y'all for your suggestions. I think there's a bug related to the Ubuntu Desktop ISO (Where would I file it?)

The live USB booted in under a minute. It worked in both regular and minimal graphics modes.

Unfortunately, the default installation did not work, as it did not write the "bootloader" to UEFI. And trying to write the bootloader to UEFI from the live USB was awkward.

It was easier to do a custom install from the Kubuntu 24.04 ISO, written to the USB stick using the same methods described before. In that way, I could make sure that the right "flags" were included in my partitions. (IIRC, the right flags makes sure that the bootloader is actually read during the boot process. I actually had a similar problem with the Ubuntu 22.04 that Lenovo pre-loaded onto this system. The grub-install that I used at that time worked seamlessly.)

After installing updates, Ubuntu boots to a blank screen with a non-blinking underscore in the upper left (Lenovo ThinkBook).

I've tried:

• I'm able to get into Recovery mode, access root and read logs, but I'm not sure where to look to start fixing it and what might be the issue.
• I also tried booting using a previous kernel, but the outcome is the same.
• I tried to disable X at boot time so it boots in text mode, but with no luck.

I see these black screens with boot messages until I get to a blank screen where it freezes.

I'm not sure how to go about debugging this. Can you help me?

I am using Ubuntu Studio 22.04, computer is connected to screen using HDMI.

Depending on the software being used (Ardour or VLC or software to manage my mixer...) I would like to have my desktop/screen rotated 90°...

I know that I can go to Settings/Displays and change the orientation, however I am looking for a quicker way to do so...

Ideally a function key or a shortcut :->

Any idea ? Thanks Vincent

In summary, my issue specifically is when I PXE boot a UEFI system, I get stuck at a grub> prompt. It appears that the UEFI systems aren't loading the grub.cfg file and I'll be damned if I can figure out why.

Since 22.04 is no longer providing us a mini.iso or netboot.iso option, I've been building (in our lab) a POC (Proof of Concept) of the 'new' way to automate deployment of systems. For the most part I've been following the instructions from these two URLs:

• https://www.molnar-peter.hu/en/ubuntu-jammy-netinstall-pxe.html
• https://www.golinuxcloud.com/uefi-pxe-boot-server-ubuntu-20-04-cloud-init/

For now my PoC is all sitting in a small Hyper-V lab. The network config is pretty simple in that I have a pfSense FW giving my lab network access to the internet and everything behind my FW is on a closed (private) network. This allows me full control over things like DHCP and such.

On what I'm calling my PXE sever, I have installed:

• apache2
• isc-dhcp-server
• tftpd-hpa

NOTE: I want DHCP to be issued by my pfSense server but I discovered the only way to get isc-dhcp-server to start was to specify some sort or range. I need to resolve this but for now it does seem that since everything is on the same subnet things are working well enough with this config.

For what it's worth, I have validated that the Apache2 directories are being served correctly, and in fact with the above config I am able to PXE boot BIOS based systems using the pxelinux.0.

For whatever reason UEFI systems (or in my case Hyper-V Gen2) get stuck at the grub> menu.

I have installed vsftpd on my Linux Ubuntu 21.04 instance using the following:

sudo apt-get install vsftpd

I have enabled FTP in my ufw firewall using the following:

sudo ufw allow ftp

My /etc/vsftpd.conf file contains the following:

# Example config file /etc/vsftpd.conf

# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.

#
# You may activate the "-R" option to the builtin ls. This is disabled by

I have added my intended user account ftpuser to /etc/vsftpd.user_list. The following is contained in the output of netstat -tanp:

tcp        0      0 0.0.0.0:27017           0.0.0.0:*               LISTEN      939/docker-proxy
tcp        0      0 0.0.0.0:21              0.0.0.0:*               LISTEN      585614/vsftpd
tcp        0      0 127.0.0.53:53           0.0.0.0:*               LISTEN      582461/systemd-reso

The above seems to indicate that vsftpd is listening on port 21 as it should be. However, I cannot connect to it using WinSCP on port 21 with the FTP protocol. However, what is strange is that I can connect on port 22 with the SFTP protocol.

I should also mention that I previously did have vsftpd installed and configured for SFTP. I did sudo apt-get purge vsftpd and have been trying to reinstall since.

Edit Even when I run ftp localhost I receive the error message : ftp: connect: Connection timed out

These are the steps I have now taken.

Install VSFTPD

sudo apt update
sudo apt install vsftpd
sudo service vsftpd status

Configure firewall

sudo ufw allow 20/tcp
sudo ufw allow 21/tcp
sudo ufw allow 40000:50000/tcp
sudo ufw allow 990/tcp
sudo ufw allow openssh
sudo ufw enable
sudo ufw status

Create ftpuser and directories

sudo adduser ftpuser
sudo mkdir /home/ftpuser/ftp
sudo chown nobody:nogroup /home/ftpuser/ftp
sudo chmod a-w /home/ftpuser/ftp
sudo mkdir /home/ftpuser/ftp/files
sudo chown ftpuser:ftpuser /home/ftpuser/ftp/files

Setup VSFTPD configuration

sudo nano /etc/vsftpd.conf

With the following entries

listen=NO
listen_ipv6=YES
anonymos_enable=NO
local_enable=YES
write_enable=YES
local_mask=022
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
chroot_local_user=YES
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
force_dot_files=YES
pasv_min_port=400000
pasv_max_port=500000

user_sub_token=$USER
local_root=/home/$USER/ftp

Restart the VSFTPD to have changes take effect

sudo systemctl restart vsftpd.service

Try connecting with Filezilla and WinSCP. Neither worked. However, just as previously, I was able to connect via SFTP on port 22.

What am I doing wrong?

I'm lately having slow startup times (90sec vs 20sec in the past) since I upgraded from Ubuntu 18.04 to 20.04.

I'm on Ubuntu 20.04.1 LTS 64-bit. I'm working on a hybrid SSD (120GB) + HHD (500GB) system, Intel Core i3-6100U CPU @ 2.30GHz × 4 and 8GB of RAM DDR4. My partitions are: SSD: 249MB EFI (/boot/efi), 40GB FileSystem (/), 8GB Swap and 72 GB FileSystem (/home). The HDD is not mounted.

I've formatted my system and re-installed Ubuntu, but the booting time is pretty much the same. I also tried to Open /etc/fstab (as superuser), remove (or comment out) the line contains old swap partition, set up a new swap:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sdc2 during installation

# /boot/efi was on /dev/sdc1 during installation
UUID=4C04-C9BD  /boot/efi       vfat    umask=0077      0       1

# swap was on /dev/sdc3 during installation
# UUID=3bd915e8-cdd5-4ffd-a477-b355a73d53b3 none            swap    sw              0       0

And, I also cancelled the Press Ctrl+C to cancel all filesystem checks in progress message at the booting by adding fsck.mode=skip to /etc/default/grub.

Here are some commands I ran for troubleshooting along with their respective output:

$ systemd-analyze time

When I restart my computer for any reason it automatically boots to this GNU GRUB black screen.

   Minimal BASH-like line editing is supported. For the first word, TAB
   lists possible command completions. Anywhere else TAB lists possible
   device or file completions.

I then have to type reboot and then go to my BIOS and select the Ubuntu install and then it boots just fine. It's not that big of a deal. It just makes me want to restart my computer less often. I'm not sure if there is anything I can do to fix it. I do not have Windows on my computer, only Ubuntu.

It has been 6 days since the last time that I edited this question, and I haven't gotten any responses. I haven't been able to figure this issue out. I tried the one answer in the comments, but it didn't help.

I am working on Python 2.7 in Anaconda in Spyder IDE. I am making a project using kivy and I am importing the following libraries and kivy packages:

import numpy as np
from random import random, randint
import matplotlib.pyplot as plt
import time

# Importing the Kivy packages
from kivy.app import App
from kivy.uix.widget import Widget
from kivy.uix.button import Button
from kivy.graphics import Color, Ellipse, Line
from kivy.config import Config
from kivy.properties import NumericProperty, ReferenceListProperty, ObjectProperty
from kivy.vector import Vector
from kivy.clock import Clock

But upon compiling the line:

from kivy.app import App 

I am getting an error in the console:

from kivy.app import App
Traceback (most recent call last):

File "<ipython-input-2-04ecba6f9778>", line 1, in <module>
from kivy.app import App

ImportError: No module named kivy.app

How can I resolve the issue?

I have an Ubuntu 16.04 dual boot installed (with Windows 7) on a Dell Latitude 6420 Laptop.

Yesterday, after the update, it requested reboot, then would not reboot completely. It got up to the user login, then would freeze after I entered my password. A couple times it also froze at the login, not allowing me to even enter a password.

After some reading, I attempted logging in "safe mode". First I experimented with logging into the first option (ending in "generic"). I could log in and use the machine with no problem. But upon logging in as normal, it continued to freeze.

After doing some more reading, I repeated the process, this time choosing the option ending in "recovery mode".

From there I chose the option, fsck... it ran and provided me with information about missing dependencies on my swap partition.

Now my computer and I are having a really awkward moment of silence. It is holding, exactly as you see in the above boot messages, waiting for me to do something, I suppose. And I'm here waiting for it to indicate to me what I'm supposed to do next.

So I have 2 questions:

1. What do I do next?

2. How do I go about remedying the missing dependencies? Or is fsck supposed to do this?

Additional info:

'exit' worked to get me out of this screen, and back to the grub/recovery mode menu

From this menu, choosing root access, then entering 'sudo fsck -f /' at the prompt, produced this response:

Root access:

Then I rebooted. Normal boot still didn't work, so I rebooted again into the generic option. I ran the following:

sudo blkid

NOTE: Whereas booting into generic worked normal before, I now have no internet. When I open the Network Settings, and try to switch on Wi-fi, it flips itself back off. It does not work on the Windows side either. Windows does boot up normally otherwise.

Then I rebooted with the Boot Disk, ran gparted and snapped this image:

Update:

With every reboot, I keep checking to see if I can log in normally. Before being able to implement the suggestions below, my machine booted normally, in normal mode, but still without wi-fi (I have not yet attempted to wire it into the modem directly)

While booted normally, I checked all of the following:

gparted (corrected)- all partitions that are supposed to be encrypted are. I will add photo here in a few.

sudo blkid (changed) - there is a new line at the bottom containing an UUID for cryptswap1 that wasn't there before:

/dev/loop0: TYPE="squashfs"
/dev/loop1: TYPE="squashfs"
/dev/loop2: TYPE="squashfs"
/dev/sda1: LABEL="System Reserved" UUID="2C2A0DEA2A0DB23E" TYPE="ntfs" PARTUUID="f752fb6f-01"

/dev/mapper/cryptswap1: UUID="e9166797-d813-4430-ab6e-d2f060ca59c5" TYPE="swap"

cat /etc/fstab - the same, no change.

cat /etc/crypt* - the same, no change.

So I could no boot in normally, so my immediate problem was remedied. I rebooted into grub and ran fsck again, and there were still the same dependency errors.

So I entered into the grub root prompt as directed below and made the suggested changes. It did not boot normally. In generic mode I was able to grab a screenshot of gparted. Now the home partition is encrypted, but not swap.

I then realized what direction @heynnema was going and noticed that new UUID in fstab and reworked his instructions using that UUID. Now it boots normal AND all partitions are encrypted as they should be.

However, when I go back into grub and run fsck, the same dependency errors are still there.

I'm not sure if I should count this as solved. I do have full access of my computer (sans wi-fi), and have successfully exited the grub.

Are the dependency errors something I need to worry about? I thought dependencies were parts of update files and such - is the content I was adjusting also considered dependencies?

(The WiFi issue, I'll put in a different post)

The learning curve is steep.

fsck in grub menu produced same dependency errors.

I notice however, that in the TIME line, parts of the number match the UUID for the old cryptswap1 - but not an exact match. I kept it in case I needed to change it back.

cat crypttab.old

#cryptswap1 UUID=ce2b005b-dea2-4808-86eb-71884dfeb5c4 /dev/urandom swap,offset=1024,cipher=aes-xts-plain64

I looked in the /dev/disk/... that it indicates and found this:

It's like it's looking for something that's not there, but all of my partitions seem accounted for.

After disk format and installation of Ubuntu I have a problem with boot. System doesn't want to start.

There is info: 'boot device not found'

It seems that system doesn't see the bootloader / disk is not mounted.

Could you help me?

My partitions look like this:

I tried to use 'Boot-Repair' tool, but it didn't solve the problem.

I have followed these procedures:

sudo apt-add-repository ppa:pipelight/stable
sudo apt-add-repository ppa:ehoover/compholio
sudo update
sudo apt install wine-staging
sudo apt install --install-recommends pipelight-multi
sudo pipeline-plugin --update
sudo pipelight-plugin --enable silverlight
sudo pipelight-plugin --enable flash
pipelight-plugin --system-check

Here I am getting the following error:

What to do now?

I am new to Ubuntu. I installed Ubuntu 14.04 a few days ago and encrypted the disk. For some reason I decided to reinstall it with the help of a USB stick, but it failed to do so. The reason may be the encryption (I was thinking that reinstalling totally reset everything because I have the passphrase of the encrypted disk). Now whenever I am booting GNU GRUB 2.02 is appearing. I am also unable to reinstall Ubuntu 14.04. Please help me to step forward.

Is there any criteria to decrypt it and reinstall it again?

GParted:

My server is running Ubuntu 14.04. My laptop, which is running an RDP client, is also running Ubuntu 14.04. I want to connect to my server and be able to listen to videos over the connection.

How do I stream audio over a remote desktop connection between two Ubuntu machines?

EDIT: I just remembered that on some occasions I'll be using SSH port-forwarding, so any ports beyond 5900/3389 would need to be forwarded (if required).

I found this thread that says how to delete GRUB2 Uninstalling GRUB from UEFI laptop but I'm not sure if it applies to me or if I'm doing the things correctly. I would appreciate if you guide me what to delete and what to rename. I want to remove GRUB2 and restore the partition to the original state. (It came with Windows 8.1 pre-installed).

According to the thread, deleting the Ubuntu and GRUB folders should be enough, but I feel it won't be enough since there are weird things like /EFI/EFI/Ubuntu (Why two folders with EFI?) /EFI/Boot and EFI/EFI/Boot, etc. You will see in the screenshot, but my instinct tells me, deleting won't be enough.

since I heard I could have windows 8 and Ubuntu running at the same computer (using the same HD) i was really exited to test, but unfortunately i'm not being luck doing that :(

My Computer details:

• Notebook - Dell Inspiron 15R
• 8Gb RAM
• 1 TB HD Sata3
• 30gb SSD
• Video Card - ATI Radeon HD7700

I was running windows 8.1 without any problem, so here what I did:

• I create a partition with 100gb (using windows disk utility)
• I enable legacy boot (disabled uefi and security boot) and changed the dell smart HD control to AHCI
• Started the ubuntu installation using ubuntu 12.04 iso
• I did the default procedure, advanced options -> create 4 partitions (/, /home, /boot, swap)
• When the installation was done I started the live ubuntu 12.04 and I used boot-repair as the tutorial informed to do.

The linux is running perfect but I can't log in windows anymore :(

I can see on grub2 some options, but when I try to load windows 8 i get:

• Dell recovery screen (the options simple doesn't help me, it says I need to unlock or get permissions of the installation, but the prompt works fine)
• An screen saying about an unknown issue, some hdx(100,200 blabla bla)
• I tryied boot repair a lot of times and I don't know how I installed a different boot as well that starts grub
• Since the prompt works fine I tried the MBR fix procedure and also the boot recovery procedure using disk utility
• I also tried:

bootrec fixmbr 
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

bcdedit /set {default} device partition=c:
bcdedit /set {default}
osdevice partition=c:
bcdedit /set {bootmgr} device partition=c:

Now I still can boot Windows 8, I know Windows 8 sucks, but I really need it since some applications I need only run on Windows.

Pastebin links:

• http://paste.ubuntu.com/6462192/
• http://paste.ubuntu.com/6465662/

I understand it may be a duplicated case, but I spent the last day trying to figured out how to solve it, but I couldn't solve it. That's why I'm creating and asking with my information.

After the installation I changed the boot mode to UEFI security off (since I didn't choose Boot-Repair to create ssh keys with the security boot)

I'm trying to configure GRE tunnel (between 2 VBOX ubuntu server 12.04 LTS on win 7 host) but it keep failed.

The configuration in /etc/network/interfaces

# VBOX A
ip address 172.168.1.1 /24
ip tunnel 10.0.201.1 /24

# VBOX A
iptunnel add tunX mode gre remote 172.168.1.1 local 172.168.2.1 ttl 225
ifconfig tunX 10.0.201.1/24
ifconfig tunX up
ifconfig tunX pointopoint 10.0.201.2
ifconfig tunX multicast

# VBOX B
ip address 172.168.2.1 /24
ip tunnel 10.0.201.2 /24

seting tunnel di VBOX B
iptunnel add tunY mode gre local 172.168.2.1 remote 172.168.1.1 ttl 225
ifconfig tunY 10.0.201.2/24
ifconfig tunY up
ifconfig tunY pointopoint 10.0.201.1
ifconfig tunY multicast  

But ifconfig shows the tunnel is up

Are there any other way to configure the GRE tunnel to start on reboot beside /etc/network/interfaces configuration???

There is a chmod command to set file permissions, but can I get file permissions in octal mode (such as 755) from the command line?

I'm running Ubuntu 12.04 on a Lenovo x61s Thinkpad. As the screen's rather small and I want to do some video editing, I thought I'd plug in a monitor and use that. The monitor is Relisys JM777 (quite old).

When I plug it into my other computer, which is running Windows 7, it immediately mirrors the display; but when plugged into the Lenovo the monitor screen remains blank. The graphics card on the Lenovo is a "VGA compatible controller" according to SysInfo.

Anybody got any suggestions for getting this monitor to work? I'm quite new to Linux.
