Out of nowhere, my laptop is missing the Wi-Fi and Ethernet drivers. I tried USB tethering, but it didn't work. I installed some packages, but still no success. Has anyone else experienced this?
im trying to make an user that have to change the password every time it logs, so if for example the first time it logs it will ask for a new password and when he logs out and try to log in as well it will have to change the password again.
Sorry in advance for my bad english.
I get these Authentication Required dialogues all the time, at startup for enabling the Wifi, for any other Wifi action (even Wifi scanning), also for automatic suspending the system, and for many other things.
Specifically, it says:
Window title: Authentication Required - PolicyKit1 KDE Agent
Title: System policy prevents control of network connections
An application is attempting to perform an action that requires privileges. Authentication is required to perform this action.
Action: Allow control of network connections
ID: org.freedesktop.NetworkManager.network-control
Vendor: NetworkManager
I'm on Ubuntu 24.04 with KDE. This isn't too unusual, or is it?
Is this normal? Do others also see this in KDE? Is this related to KDE?
This system has been through several Ubuntu upgrades over the years. I think I started maybe with Ubuntu 16 (not sure...). Some left-over older configs might be the cause? Or some not-correctly-updated configs?
Note: I don't want to edit some files and do some custom edits. For many of the suggestions that one can find when searching for this problem, it is often suggested to write some custom polkit rule which would avoid the authentication. But I assume with the default Ubuntu configuration, I should not see this (right?). So, I don't want to write custom configs. I just want to get back the original Ubuntu configurations where I would not see this.
I already investigated quite a bit:
/etc/network/interfaces does not exist. There is nothing left over there from an older Ubuntu.
loginctl show-session $XDG_SESSION_ID -p Active gives Active=yes.
/etc/NetworkManager/NetworkManager.conf is correct.
I have policykit-desktop-privileges installed.
I have kubuntu-settings-desktop installed.
journalctl -b --no-pager | grep polkitd showed:
Nov 27 10:32:41 ... polkitd[2584]: Identity 'unix-group:admin' is not valid, ignoring: No UNIX group with name admin: Success
There was no admin user. But this comes from a rule which is also present in the latest polkit package. I also tried to create such an admin group, but this does not really change anything.
My user account is (and always was) part of the sudo and netdev groups.
/etc/polkit-1/ just contains some empty directories, no files.
/usr/share/polkit-1/ has some relevant files. E.g. /usr/share/polkit-1/rules.d/49-ubuntu-admin.rules:
polkit.addAdminRule(function(action, subject) {
return ["unix-group:sudo", "unix-group:admin"];
});
/usr/share/polkit-1/rules.d/50-default.rules:
polkit.addAdminRule(function(action, subject) {
return ["unix-group:sudo"];
});
/usr/share/polkit-1/rules.d/org.freedesktop.NetworkManager.rules:
polkit.addRule(function(action, subject) {
if (action.id == "org.freedesktop.NetworkManager.settings.modify.system" &&
subject.local && subject.active &&
(subject.isInGroup ("sudo") || subject.isInGroup ("netdev"))) {
return polkit.Result.YES;
}
});
/usr/share/polkit-1/actions/org.freedesktop.NetworkManager.policy:
...
<action id="org.freedesktop.NetworkManager.network-control">
...
<defaults>
<allow_any>auth_admin</allow_any>
<allow_inactive>yes</allow_inactive>
<allow_active>yes</allow_active>
</defaults>
</action>
...
/var/lib/polkit-1 maybe has some relevant files. E.g. /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla. I also installed polkitd-pkla now.
I searched for *.dpkg-dist or *.dpkg-new files but there are basically none.
I did sudo apt install --reinstall -o Dpkg::Options::="--force-confmiss" -o Dpkg::Options::="--force-confnew" network-manager
I was also testing with pkcheck.
I was now testing for some other unrelated action ID which should work without password (right?):
$ pkcheck --action-id org.freedesktop.login1.power-off --process $fish_pid --allow-user-interaction
polkit\56retains_authorization_after_challenge=true
Not authorized.
I was wondering how much the process ID matters here? So I was checking my process tree (ps --forest -u $(whoami) -o pid,comm,args):

The shell did not work. kwin_x11 did not work. kded5 did not work. systemd did not work. But interestingly, the startplasma-x11 did work? I.e. pkcheck --action-id org.freedesktop.login1.power-off --process 3330 returned with exit code 0.
Hm, loginctl session-status looks weird?

Maybe the chrome-remote-desktop installation that I did some time ago is messing this up somehow?
Maybe related:
I use Zoom and other video chat programs frequently and I need the webcam for meetings but don't really want to show the stuff in the background, given this I tested Web and clients to find that every time I try to blur the background or adding a custom background the webcam image straight up freezes and just just removing the blur the video returns to working.
Tested in Zoom web (chrome) and Linux client (installed from app center), Teams on web and PWA app and video with blurred or custom backgrounds works fine. Other non chat apps like Cheese also blurs and apply effects without breaking the video.
Used Firefox for web based tests and video is working with blurred background and with customized backgrounds
Running Ubuntu 24.04.3 on Lenovo P16s (latest model) with all additional drivers installed. webcam working as intended just blurred or custom backgrounds stops video streaming

I'm having a hard time figuring out the best place to ask this question, but starting here since the problem started when I updated Ubuntu from 25.04 to 25.10 last month. In a nutshell, I have two physical volumes in my laptop, and after updating 25.10, Ghostscript can no longer write PDFs to one of them (but only one of them).
My hardware setup is as follows:
Boot drive that includes $HOME (i.e., /home/user).
Second physical drive, symlinked from $HOME to store the bulk of my data. My main documents directory, therefore, is physically located at /mnt/data/user/Documents, though user@machine~/Documents$ pwd returns /home/user/Documents.
ETA: Both drives use ext4.
I am using Ghostscript, and particularly the ps2pdf script, as part of a LaTeX workflow for a document I update every month. I use TeXLive 2025 and my document makes heavy use of pstricks, so pdflatex is not a good option for me (and yes, I realize there may be options for working around Ghostscript, but I occasionally use it for other purposes so would like it to work regardless).
Here is the now-problematic workflow for a small, two-page test document when I execute it in ~/Documents (but I run into the same error regardless of the document):
$ latex test.tex
...
Output written on test.dvi (2 pages, 436 bytes)
...
$ dvips test.dvi
...
[1] [2]
$ ps2pdf test.ps
GPL Ghostscript 10.05.0: **** Could not open the file test.pdf .
**** Unable to open the initial device, quitting.
I also tried skipping the ps2pdf script and using a simple Ghostscript command directly, with the same result:
$ gs -sDEVICE=pdfwrite -sOutputFile=test.pdf test.ps
GPL Ghostscript 10.05.0: **** Could not open the file test.pdf .**** Unable to open the initial device, quitting.
This happens no matter which subdirectory of ~/Documents I use, and also in other directories that are physically located on /mnt/data (e.g., ~/Pictures). However, if I run it in $HOME (or subdirectory of $HOME that is physically located on my boot drive), the PDF is produced without error as it has been every month for the last 6 years. Hence my conclusion that the problem is related to the physical volume somehow.
What I have tried:
Reinstalling ghostscript.
Checking directory owners and permissions.
$HOME: drwxr-xr-x 52 user user
/mnt/data/user: drwxrwxrwx 11 user user
/mnt/data/user/Documents: drwxrwxr-x 56 user user
Owners and permissions for all subdirectories of /mnt/data/user appear to be the same as for /mnt/data/user/Documents.
Running sudo ps2pdf test.ps, which gives the same error as when running as user.
Providing the full path to the input file, both as ps2pdf /mnt/data/user/Documents/test.ps and ps2pdf ~/Documents/test.ps, which gives the same error.
ETA: Adding the -dNOSAFER flag to the direct gs command makes no difference (and as far as I can tell, it is included in the command ultimately generated by ps2pdf).
Ghostscript is the only application for which I have experienced this problem, and only since the update to Ubuntu 25.10. I believe, but am not 100% sure, that the Ghostscript version was 10.05.0 for both 25.04 and 25.10, but I think it could have been 10.03.1 on 25.04.
I use VLC to monitor a DVR via RTSP. Suddenly it stopped connecting. I have tried everything I can find, but it still fails to connect.
VLC version is 3.0.16 Vetinari. It used to work, then about a week ago, it started to fail, giving:
"Your input can't be opened: VLC is unable to open the MRL 'rtsp://192.168.1.195:554/ch04/0'. Check the log for details."
I have tried removing and reinstalling, both with Symantic and 'sudo apt install', which I think means snap. I tried 'sudo apt-get install', but it makes no difference. I have a log output, very long, but I cannot understand what it is telling. I can post it if it would help.
This first started on my daily-use Desktop, for a day the backup laptop worked, then it also failed. I assume there was some kind of update that borked it. The laptop has 3.0.20 Vetinari.
I want to open a terminal and automatically open a folder and run a command within it
For this, I have the following:
:~$ gnome-terminal --working-directory=/home/project -- code .
This runs code . (opens VSCode in the current folder) after it opens the terminal in /home/project.
Is this behaviour guaranteed that it will navigate to the working directory and then run code .
I ask because I do not want code . to run in the current directory from where the command is issued and then the terminal opens in the working directory.
This seems to work fine if the working directory exists. But if /home/project does not exist, I want the entirety of the above command to fail. At present, it still runs code . if the working directory does not exist in the current folder from the above command is issued.
behaviour is following:
only solution for me now, is each time to "rmmod btusb btintel && modprobe btusb btintel". but once the laptop is log out and back, the BT icon can not be turned on again.
I would like to install Ubuntu 25.10 as the exclusive OS on a old MacBook and would like to use macOS-style keyboard shortcuts — for example Command+C for copy, Command+V for paste, and Command+Tab to switch apps. Is there a way to make the Command (⌘) key behave like Ctrl system-wide in Ubuntu? Ideally a simple solution that works across all applications.
As in the title. I'm trying to get two snap packages updated, but the Updates report is apparently very stuck.

Is it safe to kill and restart?

I can't actually remember the icon/button I clicked in the "Updates" tab to start the Check for Updates, because the process is apparently still running and won't stop.
Sequence of events:
I can't figure out what actual program is running. The only .desktop files I can find associated with software and/or updates (e.g. /snap/snap-store/[version]/ubuntu-software-service.desktop, meta/gui/ubuntu-software-local-file.desktop, meta/gui/ubuntu-software.desktop, meta/gui/show-updates.desktop, etc.) info don't seem to have an identifiable process attached. (ps -ef | grep -Ei '(software|update)' | less) show a kworker/R-hfi-update, which seems irrelevant.
using "lockscreen extension" to customize my lock screen - looks and runs GREAT with Linux 6.8.0-85-generic kernel, but every other kernel since then (6.8.0-86, 6.8.0-87, and latest 6.8.0-88) restoring goes to the grub-customizer fancy login screen instead (bummer) ~ WHY?
All the newer kernels do fine resuming from suspend and going to my fancy lock screen, just restoring using them has this weird 'BUG'.
The other 'BUG' these newer kernels seem to be afflicted with is when restoring, my USB wifi gets rerouted (from router) to the one my PCI wifi uses (an extender) - normally this only happens upon initial boot, even with my favorite Linux 6.8.0-85-generic kernel. But upon restoring it stays with router... but not with newer kernels that reroute it to the extender :-\ They do fine leaving it alone resuming...
assumed it would be understood based on kernels used 24.04lts and kernels are indicated above... 'flavor'? like wayland? Other kernels that 'worked well' was 6.8.0-53, 6.8.0-79 and 6.8.0-84 - no issues with those...
I read askubuntu.com/help/how-to-ask and took the tour - so, couldn't find anything 'violated'... what gives? ...such zeal to close ~ wow!
should I just use forum.linuxconfig.org instead of askubuntu?
In this post: How can I revert a config file back to the originally installed version after I have edited it? Someone said
Because the other options in dpkg doesn't work well.
Is there a Bug reference in Ubuntu database describing these issues ? I am trying to overwrite changes to config files when installing a package, and although I installed with -o DPkg::Options::="--force-confnew", local changes to config file are NOT overwriten.
I am running an Ubuntu jammy, currently installed packages versions are:
linux-image-generic 5.15.0.161.157
dpkg 1.21.1ubuntu2.6
apt 2.4.14
From reading previous mentioned thread, I understood that I should try using these options for it to work as expected: -o DPkg::Options::="--force-confnew" -o DPkg::Options::="--force-confask" [-o DPkg::Options::="--force-confmiss"]
I tested with all 3 options (--force-confnew, --force-confask, --force-confmiss"). And local changes to my config file are still NOT overwritten !
Copying logs with dpkg debug activated (the modified config file that should have been rewritten is utl-infra.conf):
# apt-get -o APT::Get::Allow-Downgrades="true" -o APT::Get::Assume-Yes="true" -o Dpkg::Options="--force-confnew" -o Dpkg::Options="--force-confmiss" -o Dpkg::Options="--force-confask" install x-ntp=1.5-2804-5248a1af

And I am pretty sure file is detected as a conffile, and has been localy modified:
# dpkg --status x-ntp | grep utl-infra.conf; md5sum /etc/chrony/x-ntp/utl-infra.conf
/etc/chrony/x-ntp/utl-infra.conf 9e55a85dead233239a86f204453ed488
c95324d1befd427a7e4c9686fc86a5cd /etc/chrony/x-ntp/utl-infra.conf
I did an additional test to compare results of following 2 commands (the first one does not overwrite conffile changes, the second does):
apt-get ... -o Dpkg::Options="--force-confnew" -o Dpkg::Options="--force-confmiss" -o Dpkg::Options="--force-confask" install x-ntp=1.3-20250918111734
dpkg -i --force-confnew --force-confmiss --force-confask ./x-ntp_1.3-20250918111734_all.deb
Only noticeable differences in dpkg debug logs are on line
with apt: D000020: deferred_configure '/etc/chrony/x-ntp/utl-infra.conf' (= '/etc/chrony/x-ntp/utl-infra.conf') useredited=1 distedited=0 what=2
with dpkg: D000020: deferred_configure '/etc/chrony/x-ntp/utl-infra.conf' (= '/etc/chrony/x-ntp/utl-infra.conf') useredited=1 distedited=0 what=3
Note that this 'x-ntp' package is a proprietary package that we developped internaly. But is has nothing special, it just installs a couple of files to /etc and /usr, it does not have any: pre/postinst, pre/postrm, service, triggers, diverts ... . It is successfully installed and files copied to /etc are correctly detected by dpkg as conffiles, so I do not think the issue is anywhere inside this package (unless something special needs to be declared for config files if you need them to be correctly overwritten when using --force-confnew).
I have a brand new Xubuntu 25.10 system. Canon printer driver cnijfilter2-5.90-1-deb fails to install with dependency on libxml2.
The install.sh script says it wants libxml2 >= 2.7.4 But dpkg appears to show libxml2 2.14.5+dfsg-0.2 which is higher than 2.7.4
This worked on all earlier versions of *ubuntu that I've tried. 25.04, 24.10, even 16.04.
Typescript from the installation is below.
If anyone can suggest a solution, I'd appreciate any hints or tips.
Thank you for reading this

After upgrading my system from Ubuntu 24.10 to 25.04, the command:
$ pro security-status --unavailable
lists (among the known, manually installed packages by me) the following packages too: kerneloops, chrome-gnome-shell, and policykit-1.
I get the same list using the command:
$ apt --installed list | grep ,local
Doing a search in https://packages.ubuntu.com/ reveals also that these are not available in plucky.
What is the recommended action?
Comments for @heynnema :
The package policykit-1 is still installed on my system:
$ apt --installed list | grep -i policykit

I'm kind of new into the Linux ecosystem and still struggling with some parts of it.
I'm trying to use the internal webcam of my laptop but it runs at an extremely low framerate (maybe talking about 1 fps). I've tried cheese, kamoso and snapshot applications but all have the same issue.
Also, when running any of the applications through the terminal, I get the following message:
(cheese:30042): cheese-WARNING **: 23:54:10.415: Can't find vp8enc preset: "Profile Realtime", using alternate preset: "Cheese Realtime". If you see this, make a bug report!
(cheese:30042): GStreamer-WARNING **: 23:54:10.415: gst_value_deserialize_g_value_array: unimplemented
[last message repeated repeated several times]
** (cheese:30042): WARNING **: 23:54:10.505: could not generate thumbnail for /home/carlangas/Videos/Webcam/2025-01-04-235306.webm (video/webm)
(cheese:30042): cheese-WARNING **: 23:54:11.831: A lot of buffers are being dropped.: ../libs/gst/base/gstbasesink.c(3143): gst_base_sink_is_too_late (): /GstCameraBin:camerabin/GstViewfinderBin:vf-bin/ClutterGstVideoSink:cluttergstvideosink0:
There may be a timestamping problem, or this computer is too slow.
Nevertheless, the app still launches, but showing video at a frame rate of 1 fps.
My camera devices are the following:
$ v4l2-ctl --list-devices
HD Webcam: HD Webcam (usb-0000:00:14.0-5):
/dev/video0
/dev/video1
/dev/video2
/dev/video3
/dev/media0
/dev/media1
but actually, video0 is the real HD camera and video2 is an infrared camera. For me it is very curious that the infrared camera works perfectly, and it is detected by the different softwares. For example, this screenshot is from cheese:
but is the normal HD camera the one that fails and output the error message.
I have also tried to output video using gst-launch with the following command:
gst-launch-1.0 v4l2src ! videoconvert ! autovideosink
getting a very similar error:
WARNING: from element /GstPipeline:pipeline0/GstAutoVideoSink:autovideosink0/GstXvImageSink:autovideosink0-actual-sink-xvimage: A lot of buffers are being dropped.
Additional debug info:
../libs/gst/base/gstbasesink.c(3147): gst_base_sink_is_too_late (): /GstPipeline:pipeline0/GstAutoVideoSink:autovideosink0/GstXvImageSink:autovideosink0-actual-sink-xvimage:
There may be a timestamping problem, or this computer is too slow.
I have also tried different sinks such as xvimagesink and glimagesink without success.
The only thing that worked was to add the flag sync=false to the gstream command, but still don't find a solution for the webcam issue. Also, if I try to stream video using the infrared camera with the command gst-launch-1.0 v4l2src device=/dev/video2 ! videoconvert ! glimagesink it actually works.
Other things that I've tried were to output video using ffplay:
ffplay -f v4l2 -framerate 30 -video_size 640x480 -i /dev/video0
and checking in online video-call apps like google meet, and both options worked perfectly! So it seems to be an issue with gstreamer or its configuration.
The output I get when I run gst-inspect-1.0 | grep sink is the following:

The current version of the.net 8 SDK on Ubuntu 24.04 is 8.0.105, but the latest is 8.0.302. Are there any plans to upgrade the package? When will it be available?
Tks
I've just installed Ubuntu 22.04.3 LTS. Set up SSH as I have done for years.
In /etc/ssh/ssh_config changed:
PasswordAuthentication no
PubkeyAuthentication yes
ChallengeResponseAuthentication no
Restarted the service systemctl restart sshd
I can still log in by Password.
It seems /etc/ssh/sshd_config.d/50-cloud-init.conf
contains a line PasswordAuthenticaion yes which overrides ssh_config
To my way of thinking this is a security flaw introduced by Ubuntu in this release as it breaks years of tradition and standard practice where disabling password authentication in sshd_config has worked. I can imagine a releaseupdate potentially changing a setting or a standard config being thrown in place by scripts and getting subverted by this change.
Is there a reason for this change or is it a mistake in this release?
Thanks
When I try to run a program using dotnet I get this error:
> dotnet OmniSharp.exe
A fatal error was encountered. The library 'libhostpolicy.so' required to execute the application was not found in 'path/to/exe'.
Failed to run as a self-contained app.
I found the file libhostpolicy.so in /usr/lib/dotnet/shared/Microsoft.NETCore.App/7.0.9/libhostpolicy.so, so I have no idea why dotnet can't access it.
I read on here that doing this will solve it:
sudo chown -R yourusername:yourusername /path/to/exe
sudo setfacl -R -d -m u:yourusername:rwx,g:yourusername:rwx,o::r /path/to/exe
but I still get the same error.
When rebooting or shutting down a headless server, the ssh connection disconnects immediately.
Sometimes the server takes hours to reboot or shutdown. Since it's headless, all I can do is wait.
Can I keep the ssh connection open as long as possible so that I can know what is happening?
I have a "HP ZBook 15v G5" which I'm trying to get the "recommended" Nvidia graphics drivers working with.
Running the following suggests nvidia-driver-455 are the recommended ones:

But when I try to install them automatically I get:

The following information may help to resolve the situation:
The following packages have unmet dependencies.

E: Unable to correct problems, you have held broken packages.
Not sure if it's worth noting I did upgrade from Ubuntu 18.04 but hadn't got them working on that either.
Apologies if this is obvious, don't have much experience with graphics drivers on Ubuntu yet.
Appears I'm using the Nouveau display drivers at the moment, and I'm trying to update them to the Nvidia ones because occasionally my second monitor will go black for 10 or 15 seconds when switching applications, and then come back again:
My Qualcomm Atheros QCA9377 Wireless adapter is not working. In that I can't use WiFi in my Ubuntu 20.04 version. Also my laptop vendor is Lenovo(Model:E41-25) Already I referred some of the solutions here on AskUbuntu.
I can use my WiFi adopter in Windows but not in Ubuntu.
I'm searching this for more than 4 months Still I didn't get the solution.
Please help to find the solution.

I have installed Ubuntu with the minimum setup instead of the normal install. I am trying to connect into Ubuntu but Sharing will not stay on. (I would like to use vnc)
I'm running Ubuntu 19.10. NetworkManager constantly asks for the admin password with "System policy prevents wi-fi scans" I've seen online instructions for how to disable this with polkit, but nothing seems to work. What is the current way to set polkit rules? I'm also prompted when shutting down.
which configuration file controls the option "Make available to other users" in the Network settings?
For users, who are in the netdev group, this option is checked by default. I would like to change that.
Best, Johanna
I have dual boot setting (Ubuntu 16.04 + Windows 10) on my notebook (using nouveau driver). Originally there was no major issues, but when I changed my BIOS configuration, my Ubuntu started to have screen flickering after boot in GRUB menu. All other things function properly in Ubuntu GUI, but the screen keeps flickering that I can hardly navigate. I encountered the same screen-flickering issue when booting in live USB. On windows side, everything is still fine and I can switch between integrated graphics card and my discrete graphics card.
I didn't find any similar situation as mine on my first attempt of internet search. Do anyone have any idea how to fix it?
Hardware specs:
BIOS Configuration** (Updated in 12/10/2019):
In my first dual boot attempt, I navigate to BIOS settings via "UEFI Firmware settings" in Windows "Advanced Startup" (attached below). The change I made on the BIOS configuration are the following:

After a few study, I added "nomodeset" on grub configuration file and it temporarily settles the issue, but it is not desirable in the long run because such configuration disables brightness adjustment on screen and HDMI connection. I will keep looking for a more sustainable solution.
[Update: 12/10/2019 - 1]
I replaced Ubuntu 16.04 with Ubuntu 18.04. On fresh installation, screen flickering still existed but setting "nomodeset" in grub configuration file temporarily settles the issue. After I installed proprietary NVIDIA driver, screen flickering still persist and in this case setting "nomodeset" in grub config didn't solve the problem. But a good news is I finally escaped the black screen nightmare and infinite login loop nightmare this time. However, screen flickering is still an annoying issue to be settled.
I tried blacklist nouveau and setting nvidia_drm modeset = 1. But the issues still persist. I will keep trying different solutions to settle that.
[Update: 12/10/2019 - 2]
On Ubuntu side, my current state is that I have uninstalled proprietary nvidia driver by the following:
sudo apt-get purge nvidia
sudo apt autoremove
sudo apt autoclean
I also blacklisted nouveau drive in /etc/modprobe.d/blacklist-nvidia-nouveau.conf with the following lines:
blacklist nouveau
options nouveau modeset=0
With such state, screen flickering issue existed and HDMI connection didn't work. And then, I followed David suggestion to set graphics mode back to default "Discrete Graphics" in BIOS configuration. Screen flickering issue disappear. I then proceed to install proprietary NVIDIA driver again by the following steps:
sudo apt-get update (sudo add-apt-repository ppa:graphics-drivers/ppa has been executed a few days ago)After the Nvidia driver installation, I didn't encounter any screen flickering issue after Ubuntu reboot, also HDMI connection seems working. HOWEVER, I got stuck in a purple screen after login page, as shown below. I can navigate to tty by Alt + Ctrl + F6. When I execute nvidia-smi, my GPU device can be detected (as shown below)
Additional Drivers tab (showing how I installed the Nvidia driver:
After nvidia driver installation, I got stuck in purple screen after login, the picture also shows HDMI works after the installation.
When I got stuck at a purple screen, I tried to press Ctrl + Alt + F7, I then got to a black screen.
nvidia-smi can detect my GPU (in execute this in my TTY mode.

Stuck in post-login for a few times, I tried to install KDE desktop in tty mode (by sudo apt-get install kubuntu-desktop). After rebooting I could finally get into desktop, but the screen flickering problem came again when I got into KDE desktop, however the screen flickering issue in KDE didn't appear as serious as the one in GNOME.
I tried changing a few configurations in System Setting -> Hardware > Display and Monitor -> Compositor. It is suggested from Flickering in KDE Plasma 5.4, but it didn't help.
I want to remove all the files and folders inside the particular directory at /var/www/example directory using user data script at AWS instance launch. Can you please help me.
What are the exact steps to run a .cu sample program? I found a sample application called vectorAdd and I don't really know how to compile and run it. The net says,
nvcc -o a.out vectorAdd.cu
./a.out
will do the job but I am getting an error
nvcc command not found
What should I be doing? PS: I am using Ubuntu 16.04, ARM
The short story is that I can SSH into my device with the a username and password that should be in the superuser group (so I should be able to sudo su). The problem is that I was trying to increase the user open file limits and I edited /etc/pam.d/common-session-interactive. I was supposed to enter this line:
session required pam_limits.so
but I stupidly entered this line instead:
session_required pam_limits.so
Note the underscore between session and required. Unfortunately, the sudo setup apparently tries to load the file /etc/pam.d/common-session-interactive and I think it is getting to that line and failing. Also unfortunately, that file is owned by root and is read only. So, to fix my sudo su problem, I need sudo su to work so I can change that file! Any ideas on how I can edit this file and fix the problem?
Okay so I have had this problem with several versions of linux two primarily being xubuntu 14.04 and Ubuntu 14.04 lts, But I have also experienced the issue with Cent OS 7. I have several issues with the current distro Ubuntu 14.04 and before I make it my primary OS I want to repair the issues. First is the waking issue, after I have closed my laptop and left it alone for several hours (sometimes not so long but sometimes I can go hours and not experience the issue) I open the laptop back up and it won't wake up from suspend. I literally have to turn the computer off and restart it. Which brings me to the next intermittent issue, after restarting the computer (sometimes not all the time) the mouse and keyboard doesn't work and it has to be restarted again to have them operational. neither of the problems are persistent but both are rather annoying. I am running a dual boot on a Toshiba Satellite L775 with Windows 7.

FileZilla is really kind of "meh," when it comes to user interface. I'm wondering if there's something simpler/cleaner/slicker out there?
At least three features are missing for me in FireZilla:
