Using gtx770 GC, I'm stuck with kernel 6.8.0-79. I'm not totally happy with it because of security flaw.

The nvidia 470 was well supported in ubuntu until kernel 6.8.0-79 (with the modules and all that ).

Nvidia stop support, that's why there was no module update for newer kernels (than 6.8.0-79, like -8* serie ).

But I heard kernel 6.8.0-100 have reintroduce it ?

What's exactly the situation today ? I have not time to break my system to test it.

If not, is there any workaround ? I need the proprietary driver for performance.

Is there any "unofficial" port ?

Thanks.

I'm getting this error message when trying to install some package.

Wrong namespace on document element in '/usr/share/mime/packages/application-x-snapgene.xml' 
(should be http://www.freedesktop.org/standards/shared-mime-info). 

Does anyone have an idea how to resolve this?

I’m experiencing severely limited CPU performance on Ubuntu in a dual-boot setup, while Windows on the same machine works perfectly.

System information

• Laptop: HP ZBook (Intel platform)
• CPU: Intel Core i7-10610U
• Base: 2.3 GHz
• Turbo: up to 4.8 GHz
• OS: Ubuntu (dual boot with Windows)
• Boot mode: UEFI
• BIOS: Recently reset to defaults
• GPU: Intel + NVIDIA (hybrid)

Problem description

On Ubuntu, the CPU never boosts properly: Under heavy load (builds, stress tests), CPU frequency stays around 1.6–1.8 GHz Turbo frequencies are never reached Performance is noticeably worse than Windows

On Windows:

• CPU boosts normally to base and turbo clocks
• No thermal or performance issues

Well been running version 23 then upgraded to 24.04.03 LTS always preferred running LTS. Going with grading something went very wrong top and htop were 4 times 100% on cpu. Pinpointed Nautilus and did decide til go on 25.10 non LTS Argh! Some major leap from 23 til 24/25. Have been here from before the Millinium. Damn. The fresh install of 25.10 were done on at new M2 NVMe 2TB and I am still stuggling with performance. Did some searches on turning off swap. But all result related to 23/24 and finds no bearing on 25.10. I feel Ubuntu is getting Bloated like Windows 11. I am happy for the Brave Browser which may not work on 24/25, Wayland??? Starting Brave sends 4 CPUs up on 100% and near system halt. On the brink of moving 25.10 to Proxmox running 16 cores and se what happens and then reinstall 23 on my aging Thinkpad with world best docking station. :D

Since I upgraded to 6.8.0-1047, I’ve been experiencing persistent networking issues. Sometimes it works, sometimes it doesn’t, and it’s getting really frustrating. What’s the best way to fix this, or how can I downgrade to an earlier version?

Here’s some context from my system:

I use Ubuntu 24.04 LTS with Gnome desktop. The system was clean installed and is fully updated.

I noticed the following issue that regularly occurs with documents opened in LibreOffice (currently on ver. 25.8.4.2):

1. In Nautilus I open a folder, select a LibreOffice document and open it. LibO starts with the document open and it has the focus so I can use keyboard to write to it.

2. I switch back to Nautilus, select another LibreOffice document and open it. The document opens but it does not have the focus - the focus has been kept on Nautilus. So I cannot use keyboard to write to the document until I change the focus (with mouse or keyboard) to the last document in order to write to it. This repeats for all subsequent documents I open in LibreOffice.

I tried using Midnight Commander (mc) from terminal window to open documents and the same issue occurred with LibreOffice documents.

It seems that this issue is specific to LibreOffice because if I open two or more PDF files (with Evince document viewer) the last open file always gets the focus. Also for txt files which open in Gvim editor.

Is there a way to change this behaviour in LibreOffice so that the last document opened always get the focus?

I normally use "Ubuntu on Xorg" at login which has the following graphics info:

$ inxi -G
Graphics:

When I select "Ubuntu" at login and the issue gets fixed. Go figure! inxi -G says:

I'd like to solve this also in X11.

During routine updates the kernel updated from 6.14.0.37 to 6.17.0.14.

Linux davidp-DT4102 6.14.0-37-generic #37~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 20 10:25:38 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

I was watching the installation and it seemed to succeed through the dkms (I have a USB wifi adapter) and then failed after that. I have since used dkms to tidy up what is in there.

I have attempted to reinstall the offending kernel (linux-image-6.17.0.4-generic), so I can get a better view of the failures. I removed the offending kernel using Synaptic, rebooted, and attempted to reinstall it.

I got the following error messages, but it's not copy/pasted, (I wrote it down), so might be a bit inaccurate.

E: linux-image-6.17.0-14-generic package post-installation script subprocess returned error exit status 11    
E: linux-headers-hwe 24.04 dependency problems - leaving unconfigured

Do you have any ideas what might be happening, and can you give me some tips on how to better debug it and get it installed correctly?

New information. I have now run the following command it help debug the problem.

sudo dpkg --configure -a 

Helped from the following: -

https://itsfoss.gitlab.io/blog/dpkg-linux-headers-dependencies-error-while-upgrading-the-linux/

this give me the following output: -

That seems to suggest I have a problem with my USB rtl8821au build which I will now investigate.

I just installed 24.04.3 fresh from the installation media. APT updated and upgraded all.

My current kernel is 6.17.0-14-generic.

lsusb shows the following line:

Bus 010 Device 006: ID 2357:0106 TP-Link Archer T9UH v1 [Realtek RTL8814AU]

lsmod shows:

• rtw88_8814au 12288 0
• rtw88_8814a 266240 1 rtw88_8814au
• rtw88_usb 28672 1 rtw88_8814au

• cfg80211 1462272 2 rtw88_core,mac80211

BUT the driver doesn't seem to be talking to the device as I have no IP and no activity light on the device like there was when using the old morronwr driver.

Using TERMINAL in Ubuntu 24.04.3lts Wayland - Linux 6.8.0-85-generic, how do I SUCCESSFULLY uninstall nautilus completely, and aferwhich, how do I reinstall it SUCCESSFULLY - dependencies and all...?

Currently, I can copy, edit, move, etc. files using terminal so drive itself and permissions seem no problem, edit using nano, etc., but nautilus seems to just want to crash (like it's corrupt) so want to reinstall, not repair, it.

from terminal:

Desktop$ nautilus

Shouldn't that be Gsk.NglRenderer, not GskNglRenderer?

OK, Daniel T, I ran dpkg -V, but no /bin lines at all:

In lieu of using termnal on the desktop, would using the RECOVERY tool from grub and dropping into root be better way to uninstall, then reboot and again to the tool to root, to reinstall nautilus?

I can run Firefox, browse away, play things, etc., and all is fine until I try to attach a file to an email which tries to bring up a nautilus type window, or try to download/save a file which also tries to bring up a nautilus type window, then it'll try but ends up crashing Firefox during the attempt. I assume a piece of nautilus is what the browser uses - same with using something like LibreOffice - try to open a file which tries to bring up the window and that does similarly...

using "LIBGL_ALWAYS_SOFTWARE=1 nautilus", I noticed I can rename a file, but try to copy it, and the freeze/blink off-on/crash happen as the window pops up (with read only message at its bottom) for where to copy it to...

Please help me for installing libtinfo5 into 24.04.1 LTS.

I almost build a program for AWE in Ubuntu 22.04.2 LTS but a new version Ubuntu 24.04.1 LTS \n \l suddenly encountered (I installed with no doubt) without libtinfo5. Then my work stopped suddenly.

Your help would be much appreciated if you could please let me know any information on the installation of libtinfo5 into the new version Ubuntu 24.04.1 LTS.

The docs suggests the snap store caches previous revisions, as well as 2 revisions locally. I'm in need to control what revision gets installed and what revision to update to (after testing the target revision).

I'm not seeing how to list all revisions for the stable channel for chromium snap. It just gives me the most available and a list of other channels, beta, edge etc. I'm only interested in listing all available revisions on the snap store.

https://snapcraft.io/docs/revisions

Revision package management

The Snap Store caches several older revisions of every snap, as does the local system. By default, 2 revisions are stored locally, while Ubuntu Core systems store 3. These defaults can be changed with the refresh-retain system option.

Setup:

• Ubuntu 22.04, clean install.
• Dell G15 5521 Laptop
• Latest firmware
• 6.0.8-060008-generic
• Nvidia 525.60.11
• X11 Ubuntu flavour of Gnome

Very randomly and very infrequently (probably once a day for me) a key appears to get stuck and auto-repeats. Pressing any other key stops the auto repeat.

This happens with the default kernel and with 6.0.8.

The problem does not occur on Windows 11. The problem does not occur when running the pre-post keyboard tests (fn key held down when powering on).

The problem occurs on multiple G15 laptops. I have one for work, one for personal use and work has 3 more. All exhibit the same random infrequent problem, but frequently enough to be complained at...

The problem does not always occur when the system is under load. Typing speed does not appear to have any influence on the issue.

dmesg does not show any thing related to keyboard or USB when the issue occurs.

I do not want to turn off key repeat (xset -r).

Is there anything I can try to narrow down where this problem is occurring?

I have looked at numerous different posts and questions but the advice is limited.

Edit 20 September 2023

We now have 8 of the Dell G15's, all up to date. All have the same issue.

The problem does not occur when running Windows.

I installed picamera2 on raspberry pi using ubuntu arch 64 bit. However, I face this error, when I import picamera2. It seems the problem only occurs on raspberry pi.

>>> import picamera2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

Any suggestion please? Thank you in advance!

I recently purchased a USB Wi-fi Adapter from Amazon for my Ubuntu server. The reviews say that it is compatible with Ubuntu 20.04, but the drivers for Ubuntu don't come on the included driver CD. I was wondering where I could find the correct drivers for the adapter. The adapter is linked below.

The adapter model is the UGREEN USB WiFi Adapter AC650: Amazon product page.

I have couple of images that are of 32MBs of size and I want to change their size from 32MBs to 100Kbs or any KBs of size without affecting its colours.

The commands I am trying are:

muhammad@muhammad-mohsin:~/scans$ find . -iname '*.png' -exec mogrify -format jpg "*.png" {} +


muhammad@muhammad-mohsin:~/$ find . -type f -iname \*.png -delete


muhammad@muhammad-mohsin:~/$ find . -iname '*.jpg' -exec mogrify -define jpeg:extent=300kb -strip -quality 90 -scale 90% *.jpg {} +

Here, first I convert a PNG to JPG that reduce its size from 32Mbs to 5.8Mbs and everything stays same but when I use 3rd command, it removes background color in image and making it grayscale sort of blurry.

However, the text is still readable but colors and background logo does not.

How I can achieve this with convert, mogrify or any other tool? I tried every possible thing so far.

I have 3 files in a directory:

aaa.jpg    
bbb.jpg  
ccc.jpg  

I can scale down an image using ImagkMagick convert:

convert aaa.jpg -resize 1200x900 aaa-small.jpg  

I want to do all the images in the directory, something like:

convert *.jpg -resize 1200x900 *-small.jpg  

but this results in files named like so:

*-small-0.jpg  
*-small-1.jpg  
*-small-2.jpg  

What I want is:

aaa-small.jpg  
bbb-small.jpg  
ccc-small.jpg  

How do I do this?

I set up a new ubuntu 20.04 server and installed BIND 9.16.1-Ubuntu. Then I copied the bind configuration from my old ubuntu 16.04.7 running BIND 9.10.3-P4-Ubuntu.

When I try to start bind on the new server I get this error.

/etc/bind/named.conf.options:15: '::1/64': address/prefix length mismatch '64'

Here is my /etc/bind/named.conf.options file.

options {
        directory "/var/cache/bind";
        dnssec-validation auto;
        auth-nxdomain no;

        listen-on-v6 port 53 { any; };
        allow-query { 0.0.0.0/0; ::/0; };
        version "DNS";

        allow-recursion {
                127.0.0.0/8;            ::1/64;

        };

        allow-transfer {
                127.0.0.1;              ::1;
        };

        notify yes;
        masterfile-format text;
};

What is wrong with this prefix?

What has changed in bind 9.16 cause same file works perfect with bind 9.10?

I'm using VS code installed via snap. The latest version has an annoying bug in it and I want to revert to the previous version, but I don't see a way to tell snap to install a specific version. All I see with snap info are the different channels which all yield to the latest version. Also on the Snapcraft website I can't select another version.

In the snap docs it says that I could revert, but this doesn't work for me, as there is no prior version installed.

I can download a snap with the specific version from the VS code website, June 2020 (version 1.47), but I personally would prefer to handle this by snap directly.

There seem to be some people with the same problem, but I didn't find a working answer:

• How to install specific package version using snap?
• Install specific previous version of package using snap?

The question summed up is: Is there a possibility to revert to an older snap version and if yes, how to do that?

I have thermal images from FLIR camera that has 2 bytes per pixel. I am not sure how I could check in Ubuntu if these images have 2 bytes per pixel or not.

Also, how can I convert a 2 byte per pixel image to a 1 byte per pixel image?

How to list all available versions of a snap which is not installed?

I'm using Ubuntu 19.04 with snap 2.39.3.

GoodDay all,

New day, new linux adventures on my home server:

Can resolvconf-pull-resolved.path be blocking my servers internet connection ?

Background info:

I updated/upgraded my server to the latest updates recently, following the routine execution of apt update && apt upgrade and went to work.

Later I was trying to ssh to my server on the static IP address I have for it, but there was no connection. Figured I needed to reboot the server and I should be good to go again and ran off again. Sometime later I ssh again to the server, still found no connection to host. By then I got worried.

Booting the system while looking to the screen I noticed the first [FAILED] to be resolvconf-pull-resolved and a bit later unable to bring op networking (second [FAILED]).

Tried some stuff already like this page, but that did not help.

Tried journalctl -xe and got a lot of stuff in red. But I did not seem to get to the bottom of why this is happening.

So now I am wondering if there are 2 problems, or that it is 1 problem that leads to another. As I know my around Linux a bit to do basic stuff, this is way above my knowledge.

Any pointers are well appreciated and I would like to say thanks in advance for any help.

I already have a new live USB stick hanging around for reinstalling the server, but then again, what is the fun in that.

PS: Other intel information on my server can be found Here.

Where I have an update hold on libtevent > hope that there is no version conflict

So again, can somebody shed light on this?

I need to convert a large number (~10k) of .xpm files generated by my code to a .gif file.

I used ImageMagick as instructed here: How to convert a PNG strip to a GIF?

But my filenames are like plot*.xpm, * from 0 to 10000 and the convert command doesn't seem to understand it right and makes a .gif file with only a few frames.

My .xpm files are like this

they end somewhere with a non-random distribution of blue and green dots. (Like a circle of blue in the middle) in say 1000th frame. (I can't include it's picture because of posting limits)

But this is the .gif file I get

I use this line of code: convert -loop 0 -delay 10 -page +0+0 /*.xpm output.gif

I think I should use another method to introduce .xpm files to ImageMagick.
What should I do?

I am in a learning phase. I could not find the command to change my time format from 12 hour to 24 hour. Can anyone please help me with this? Thank you!!

Let me describe my problem:

I have a site where I post sponsors company logos. Once I'm sent the logo (or I've googled) they are usually in rectangle size - width and height are not equal.
On my site, once you upload the logo image, you then crop it to a square.

For logos that are rectangular, I usually open them up in GIMP, increase the canvas size to a square, create a new layer of the background color and finally export it as jpg or png for the site. Quite time consuming.

I'm looking for a way to do that hopefully with just a terminal command.

EXAMPLE:

Consider this Safaricom (Kenyan Telecommunication company) logo below. It's of 650px by 380px - how can I make it 650px by 650px and then center it horizontally from the command line?

When I log in Unity or MATE by sitting down behind the display I can change keyboards. However if I connect to my work PC via xrdp and use MATE version is 1.8.1 I cannot.

I need to use keyboard layout different to US. But when I tried to add layout with mate-keyboard-properties tool I got window with completely empty lists of countries and variants.

Hard googling found no solution. Any suggestions are appreciated.

P.S. When I use Unity I have no problems with keyboard layouts.

I have an image with around 20% of its bottom filled with white color. But the image has some dots of other colors than white. I have 100s of such images which I would like to remove those dots from.

I have been using ImageMagick commands, and bash scripts to automate several tasks but I cannot find any command to fill certain percentage of an image from bottom by a solid color.

I have successfully paired Microboom bluetooth speaker to Ubuntu Laptop, using Blueman 1.23. However, even when connection is ON, I do not see the Microboom speaker in Sound settings to direct audio output to that.

I'd like to have a unity desktop accessible via VNC on a precise server machine I have running. I installed the ubuntu-desktop package. I'm launching a VNC session with the following in my ~/.vnc/xstartup file:

#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
export XKL_XMODMAP_DISABLE=1
gnome-session --session=ubuntu-2d

What could the issue be here? The content of my /usr/share/gnome-session/sessions/ubuntu-2d.session file (this is what 12.04 puts there by default) is:

[GNOME Session]
Name=Ubuntu 2D
RequiredComponents=gnome-settings-daemon;
RequiredProviders=windowmanager;panel;shell;
DefaultProvider-windowmanager=metacity
DefaultProvider-panel=unity-2d-panel
DefaultProvider-shell=unity-2d-shell

DesktopName=Unity

I don't know anything about unity-2d, but I guessed that the default session was not configured to use the launcher. I tried making the following modifications:

[GNOME Session]
Name=Ubuntu 2D
RequiredComponents=gnome-settings-daemon;
RequiredProviders=windowmanager;panel;shell;launcher;
DefaultProvider-windowmanager=metacity
DefaultProvider-panel=unity-2d-panel
DefaultProvider-shell=unity-2d-shell
DefaultProvider-launcher=unity-2d-launcher

DesktopName=Unity

But I got the following warning in my VNC log file:

gnome-session[10354]: WARNING: Unable to find default provider 'qr' of required provider 'launcher'

And the VNC session wouldn't even start with that configuration.

Is there a way to save my monitor settings? I have an external monitor at work, but each morning i have to plug it in, rearrange the windows from being side by side to being on top of each other. Can I just save this?
