How can I restore my panel for Ubuntu-Mate
https://askubuntu.com/questions/1556145/how-can-i-restore-my-panel-for-ubuntu-mateI would like to get the bottom panel to show just the icons of open programs.
How can I accomplish that ?
Ubuntu 25.04 -network unclaimed
https://askubuntu.com/questions/1556136/ubuntu-25-04-network-unclaimedI just downloaded Ubuntu and tried to connect to WiFi. On the top right there's no icon, so I searched on YouTube and found this video -> https://youtu.be/N5N49YZLNfo?si=kiuV6Du8J273vOSP
I know it's an old video with another version, however I see similar problems in the comments. I put in the terminal the command "sudo lshw -class network" and the first line is "*-network UNCLAIMED".
What should I do? :')
Boot problem can't install
https://askubuntu.com/questions/1556135/boot-problem-cant-installI'm trying to install Linux, but I can't because of a boot problem. I recently deleted Windows 7 and accidentally messed up the boot system (I have no recovery disk), so I thought I could install Linux and still use the computer. I'm able to get into the test mode but not install. I'm not a programmer, but I was able to fumble through getting boot repair. It's not giving me a recommended repair option. Here's the log it gave me.

How to sequentially rsync photos between server and workstation with periodic syncs
https://askubuntu.com/questions/1556134/how-to-sequentially-rsync-photos-between-server-and-workstation-with-periodic-syI'm a user, not a programmer, and I need help with syncing photos between my devices on Ubuntu.
What I have:
- A laptop with limited space where I upload photos from SD cards to a server using SSHFS.
- A server that stores all photos.
- A workstation that I use mainly for editing, rarely turned on at the same time as the laptop.
What I want to do:
- When I start my workstation, it should first rsync from the server to the workstation to download any new photos or updates made from the laptop.
- After that sync completes, I want to rsync from the workstation back to the server to upload any edited photos or deletions.
- Once the initial sync is done, I want the workstation to keep syncing with the server every 15 minutes, but only in the workstation-to-server direction (after the initial server-to-workstation sync).
My challenge:
- I want to make sure the first sync (server → workstation) finishes before the periodic syncs (workstation → server) start.
- I’m not sure how to schedule this properly with cron or other tools.
- I tried thinking about using
@rebootfor the first sync and then cron for every 15 minutes after, but not sure how to coordinate that.
Can someone help me create a reliable script or workflow for this on Ubuntu?
I have a sound problem with my HP Elitebook 840 G6
https://askubuntu.com/questions/1556132/i-have-a-sound-problem-with-my-hp-elitebook-840-g6My laptop is running Ubuntu 24.04.3 LTS, and I was playing an HTMP5 browser game, and during my playthrough, my speakers just suddenly stopped working. Like, no sound at all. Settings display my speakers as intended. I can confirm that the OS detects the speakers, and it even detects sound when I play it, it's just that I don't get to hear anything at all. And yes, audio works just fine through headphones. It is just the speakers that don't work. My computer info can be seen below. Info about my computer.
The thing is, after doing some internet searches, many webpages told me to check alsamixer, to force reload alsa, pulseaudio, pipewire, I even modified my alsa-base.conf file to include specific lines such as "options snd-hda-intel model=auto", replacing "model=auto" with "model=hp-headset" or "model=alc215-headset-mic", a whole bunch of stuff, still nothing. No sound plays through the speakers even though they're detected, and headphones still work just fine. What else can I do to fix this?
Laptop won't wake up half the time (sddm/kubuntu)
https://askubuntu.com/questions/1556130/laptop-wont-wake-up-half-the-time-sddm-kubuntuI have an old reliable laptop with Kubuntu that has been having increasing 'wake up' problems for the last year. When I open the lid, the SDDM background image shows up, with the time the lid was closed, but no password prompt.
I can Ctrl-Alt-F3 to a console and type username and password, but then it hangs after the motd messages without giving me a prompt.
Trying to ssh in is ineffective although ping works
If I Ctrl-Alt-Del, I see a whole bunch of [Stopped] messages, ending with Stopping systemd-user-sessions.service - Permit User Sessions (the SSD LED is full 'on' at this stage) and then it hangs and the only way out is a hard reset.
I did not find anything looking though journalctl about the last boot/shutdown but maybe I'm looking in the wrong place.
Ubuntu wireless drivers installation issue [closed]
https://askubuntu.com/questions/1556127/ubuntu-wireless-drivers-installation-issueI've been trying to install wireless drivers on my laptop with Ubuntu 10.10 through an USB cable. I was working with rtl8188eu-master file and did these commands in terminal:
cd ~/Dekstop
sudo dpkg -i dkms*.deb
unzip master.zip
sudo mv rtl8188eu /usr/src
cd /usr/src
sudo dkms add ./rtl8188eu
sudo dkms build 8188eu/1.0
sudo dkms install 8188eu/1.0
sudo modprobe 8188eu
everything seemd fine until the command
sudo dkms build 8188eu/1.0
where the system said, that the directory with this name wasn't found. I tried changing the name in the command etc. but nothing seems to work. Using the rfkill list all command shows, that wireless isn't soft blocked nor hard blocked.
Here is my wireless information:

Download all deb files using any installation method in Ubuntu [duplicate]
https://askubuntu.com/questions/1556122/download-all-deb-files-using-any-installation-method-in-ubuntuI want to download all the .deb files that are to be installed on my Ubuntu system through commands like apt upgrade, apt install, etc.
I know the basic approach, e.g:
bash
sudo apt update
sudo apt-get upgrade --download-only
cp /var/cache/apt/archives/*.deb ~/Downloads/
The purpose: Need to cover all possible terminal commands used in daily package management, including apt, apt-get, aptitude and any others to reliably download all .deb files associated with upgrades or installs.
How can I download all .deb files from any package installation or upgrade command to target directory (temporary directory is current solution, but you need to manually copy files after each command to prevent cache clean)
Thanks!
Intel Graphics not supported any longer - how to retrofit the drivers into a current kernel
https://askubuntu.com/questions/1556121/intel-graphics-not-supported-any-longer-how-to-retrofit-the-drivers-into-a-curAfter finding out that my GPU is in the list of unsupported drivers ("thanks" to Intel for dropping support for just 5 year old GPUs "Intel UHD Graphics, Gen9, Coffee Lake"), I need to retrofit the drivers from kernel 5.10. Source of information is https://dgpu-docs.intel.com/devices/hardware-table.html
Does anyone know how to
- identify the files/package I need for this
- build this all into a current kernel
If this fails, I need a newer laptop and will have to drop a Lenovo T14Gen1, I had bought less than one year ago.
Thanks in advance for some info on how to try this.
mate-panel not visible after ugprade, but process is started
https://askubuntu.com/questions/1556084/mate-panel-not-visible-after-ugprade-but-process-is-startedAfter I upgraded Ubuntu 22.04 to 24.04, mate-panel is not visible after I log in, although the process is started and also processes like clock-applet. I can open a command line and enter mate-panel --replace which makes the panel appear. The problem only occurs in my account, the guest account and other people's accounts work as usual.
What can I do to find the actual problem? If possible, I don't want to loose my panel settings.
Music files not displaying album art
https://askubuntu.com/questions/1555934/music-files-not-displaying-album-artI explore music on my free time and collect what suits me. I almost always edit the music I keep, and the process of editing and saving tends to delete the metadata thumbnails. So I take the time to find a copy of the album art and replace it. I've repeated this process thousands of times now.
You can probably understand how annoying it is for me to find that the album art is not displaying on any of my music files since recently installing Ubuntu 24.04.3 LTS.
Is this a common problem? I've researched online and cannot find any recent mention of it, let alone a solution.
The metadata is all still there, including the thumbnails. They just won't display.
In Files the Preferences are set to Show Thumbnails on All Files. Changing this to either of the other two options doesn't help.
I've tried deleting and replacing the artwork to no avail. Even the files I never edited and have the original artwork are now not displaying the thumbnails.
I've updated via System Updater.
I've run update/upgrade via the terminal.
I've installed media codecs.
Ideas?
OK, so there's just no fix.
How then can I revert to 24.04.1? I learned to deal with the unstable wifi in that version, and the thumbnailer worked fine.
Monitor changed, new monitor not recognized, resolution limited to 800x600
https://askubuntu.com/questions/1554542/monitor-changed-new-monitor-not-recognized-resolution-limited-to-800x600First things first: I am a standard user who is not knowing Linux/Ubuntu in depth, so I need a bit of support which is easy to follow. Thanks in advance.
Issue: I am using Lenovo Thinkpad T14 G1 via a Thinkpad Dock, using one of the display port connetors which is connected to a DVI-D-adapter where a DVI-D to HDMI cable is attached (the HP monitor used DVI-D as input ... via a 4 port KVM switch ... , so I did not want to change more than the cable to the monitor) with dual boot under Win11 and Ubuntu 24.04 LTS. No NVIDIA, the graphics is plain Intel.
Edit 2025-08-16 09:15 UTC Ubuntu 24.04.3 LTS, Linux 6.14.0-27-generic, Gnome 46, X11. Connected via TP Dock -> Displayport -> DVI-D Adapter -> KVM Switch -> DVI-D to HDMI Cable (this last cable was the only hardware change in order to connect the monitor). This setup works perfectly under Win11. End edit.
The old (broken) monitor was an HP LP3065 with 2560x1600 resolution. Both Windows and Ubuntu recognized the monitor and used the full display resolution.
Now I have a Dell 27 Plus S2725QC with a max resolution of 3840x2160.
Win11 recognized the monitor instantly and I am able to use the full display resolution under the described hardware configuration.
Ubuntu does nor recognize the monitor, and it does not offer a resolution above 1024x768, where the only stable resolution ends up with 800x600. The 1024x768/60 Hz is not usable as the monitor frequently displays a black screen.
The settings do not offer any means of "detecting" the new monitor.
Question: What do I need to do in which sequence in order to get the new monitor resolution to work? Root permission/sudo and editing a config file is possible for me, so I am able to do things - but I am not able to understand the last detail of the configuration files etc.
Edit 2025-08-16 09:15 UTC Additonally, I can also install software eg with apt and the like. Thanks in advance for support. End edit.
Edit 2025-08-21 10:05 UTC After a few days there is still no progress. have tried several things linke xrandr --output DP-2-3 --auto --scale 3840x2160, but it is still not solved.
Now running Ubuntu 25.04, Linux 6.14.0-28-generic, Gnome 48 (also no progress, no "identify monitors" anywhere around in the config/setup screens.
I do not want to blame this site or anyone providing help and answers here and elsewhere, but I am beginning to understand, why Linux on the desktop remains in a niche. Even in 2025 it is still hard to find answers to questions around the GUI setup. Nevertheless, I will continue to find a solution and still hope for someone to give me the hint I still need. ** End edit **
Menu windows not showing up in certain applications; ex: in Audacity, file menus don't show up; ex: File -> Export Audio
https://askubuntu.com/questions/1554257/menu-windows-not-showing-up-in-certain-applications-ex-in-audacity-file-menusIn Ubuntu, some programs have window menu programs that won't show up.
Ubuntu 22.04
Latest Audacity app image: audacity-linux-3.7.5-x64-22.04.AppImage
File -> Export Audio...
I see this: Notice the contents of the window are hidden. What's the fix?
I see this issue in other applications too, such as FreeFileSync.
Memory leak on Ubuntu 24.04
https://askubuntu.com/questions/1542592/memory-leak-on-ubuntu-24-04It seems that there are memory leak on Ubuntu 24.04?
I almost closed all the software with gui.
Then I found that the memory usage checked by free -h is 18G (usually it should be 2~4G)
My question is:
Why this abnormal memory usage happens? I've done below, but can't find the reason. When I launched a terminal to check the memory usage, I got:
zhangthird@imini:~$ free -h
total used free shared buff/cache available
Mem: 28Gi 18Gi 2.1Gi 1.8Gi 9.6Gi 9.5Gi
Swap: 8.0Gi 256Ki 8.0Gi
I use ps to calculate the total memory used by all processes, I got
zhangthird@imini:~$ ps -eo pid,user,rss,cmd | awk '{sum += $3} END {print sum}'
4204604
ps can't find which process toke the memory
The full output of ps can be found here.
zhangthird@imini:~$ ps -eo pid,user,rss,cmd

Ubuntu 23.04 - Slack notification problem
https://askubuntu.com/questions/1478528/ubuntu-23-04-slack-notification-problemSlack notifications in Ubuntu 23.04, won't go away
I have tried using:
settings set org.gnome.shell.extensions.dash-to-dock show-icons-emblems false
But this seems to disable notifications for all applications.
I just want this to work properly meaning that want to see notifications and once i check them out to have them removed.
IPv6 network on Ubuntu Server 22.04
https://askubuntu.com/questions/1441721/ipv6-network-on-ubuntu-server-22-04Can't seem to get the IPv6 network to work.
Unfortunately, I decided to reinstall the system anyway. And IPv6 doesn't work for me either.
Given: Dedicated IPv4 like: 45.80.XX.XX/32 and gateway 10.0.0.1; IPv6 subnet: 2a03:XX:XX::5b8/125 (/125 prefix) and gateway 2a03:XX:XX::5b9
Bottom line: IPv4 works fine, but IPv6 doesn’t want to do anything...
Question: Tell me, please, a possible solution to the problem with IPv6.

Force install php 7 packages on Ubuntu 22.04 LTS
https://askubuntu.com/questions/1432704/force-install-php-7-packages-on-ubuntu-22-04-ltsWhile I know that php 8 is the default PHP choice on Ubuntu 22.04, I still use php 7 for my project. When installing packages related to PHP, the dependancies always pick php-common, php-*, etc.. and end up installing php 8 on the server.
Currently I have trouble installing Composer via apt install composer
So how do I tell the system that php-* is always mapped to php7.4-* and force libraries to always pick this given php version?
Can't shutdown ubuntu 20.04
https://askubuntu.com/questions/1379628/cant-shutdown-ubuntu-20-04Everything was working fine, but suddenly i can't shutdown my ubuntu system. I've tried manually and from terminal but there is no difference. I also tried to change the grub file : sudo gedit etc/default/grub -made it so it looks like this- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force" but nothing changed.
I also tried GRUB_CMDLINE_LINUX_DEFAULT="" and trying to see which file blocks the shutdown after shutting down the system but in the end it showed Reached target Shutdown and immediately the screen turned black but the power was still on and the only way to shut it down was to press the power button for a long time.
After editing the etc/default/grub file i run the command sudo update-grub in both situations
The only thing i did was to change the root password to my system and then locking it again as it was by default. I don't know how this might affected my system.
Thank you in advance

apt update in WSL fails: Failed to fetch ... no such file or directory
https://askubuntu.com/questions/1372662/apt-update-in-wsl-fails-failed-to-fetch-no-such-file-or-directoryI already updated WSL itself (as Administrator)
> wsl --set-version ubuntu-20.04 2
> wsl --update
Which worked but still did not solve my problem inside the WSL Ubuntu 20.04.

I don't know if this is WSL related or Ubuntu related, but I guess the first as I never had such problems on native Ubuntu.
I use WSL mostly as SSH and Git client.
Anybody knows whats wrong here?

Firefox: Exiting due to channel error
https://askubuntu.com/questions/1243396/firefox-exiting-due-to-channel-errorI am new to Ubuntu, and I am having problems running Firefox 77 on Ubuntu 18.04. This is the error that shows up:

"Device Descriptor" Error on waking up from suspend
https://askubuntu.com/questions/1215325/device-descriptor-error-on-waking-up-from-suspendI'm currently struggling with my Kubuntu 18.04 system. When waking up the machine from systemctl suspend, the screen prints some lines of the following error:
[17823.756393] usb 8-1: reset high-speed USB device number 3 using xhci_hcd
[17829.064673] usb 8-1: device descriptor read/64, error -110
[17829.300671] usb 8-1: device descriptor read/64, error -2
It adds some of those lines on every wake up. Sometimes, the machine freezes and doesn't even load the login screen, so I need to reboot. I've googled the errors already, but cannot find any clue.
Hope someone has an idea and can help me.
Thank you guys!

DNS problem with mullvad VPN on 18.10
https://askubuntu.com/questions/1088031/dns-problem-with-mullvad-vpn-on-18-10My mullvad VPN was working, then I upgraded to 18.10. Now when I use their UI client, it connects fine, but DNS is not working. I can ping google.com by IP but not by google.com.
I can resolve it by specifying the interface:
>resolvectl query google.com
google.com: resolve call failed: All attempts to contact name servers or networks failed
>resolvectl -i tun0 query google.com
google.com: 216.58.212.174
-- Information acquired via protocol DNS in 1.1ms.
-- Data is authenticated: no
The man page for resolvectl says this about the -i option:
Note that this option has no effect if system-wide DNS configuration (as configured in /etc/resolv.conf or /etc/systemd/resolve.conf) in place of per-link configuration is used
So is my system using per-link configuration? How do I check that?
Other info:
>ls -ld /etc/resolv.conf

Any ideas?
EDIT: so far I tried:
- Install lib32z1 lib32ncurses5
- Install network-manager-openconnect network-manager-openconnect-gnome
- Install different versions (4.2.01022) but I have problem with this error: vpnagentd.service changed on disk. Run 'systemctl daemon-reload' to reload units. After running systemctl daemon-reload error occurs again. Reboot or reinstall vpn client did not helped.
- and ofc. many reinstalls of vpn client and reboots
To be honest I have no idea, what can I do with timeouting vpnagentd.service.
EDIT2: I already gived up to set up vpn. But thanks to comment I walked through my tries and I installed anyconnect-4.3.05017 (after first run client was updated to 4.4.03034). Surprise! This version works! Many thanks guys.
Bluetooth disabled and not showing up in LSPCI - ASUS G750JM
https://askubuntu.com/questions/521190/bluetooth-disabled-and-not-showing-up-in-lspci-asus-g750jmThe modem installed properly on 14.04, it worked on installation of ubuntu. It's a Broadcom modem, and it's tied into the Broadcom bluetooth card. But the bluetooth does not function on 14.04. Ubuntu says it's disabled what can I do to fix this? It doesn't say that it's not there, it just says disabled even after I turn it on.

Am I to assume that since it doesn't list bluetooth anywhere in that list that Ubuntu just doesn't realize that I have a bluetooth device? It would explain why I've tried virtually everything to enable it but it won't work. Please help.
UPDATE:
Since upgrading to 14.10 bluetooth works as long as I rfkill unblock all
UPDATE:
and now since I removed ubuntu and reinstalled from scratch 14.10 it works fine without a hitch

Cursor positioning using mouse in bash possible?
https://askubuntu.com/questions/433959/cursor-positioning-using-mouse-in-bash-possibleIn Vim I can actually position the cursor in insert-mode using the mouse. So I assume this should (technically) also be enable-able for the bash. Is it possible? This would be quite useful at times when small changes have to be made to very long commands.
(I am using fish actually, but I guess referring to bash I reach a wider audience.)
eCryptfs: Input/output error
https://askubuntu.com/questions/65248/ecryptfs-input-output-errorMy home directory is encrypted using ecryptfs. I have recently started getting I/O errors when I try to access some files on that file system:
aix@aix:~/.evolution/mail/imap/acct/folders/INBOX$ cat 130395.HEADER
cat: 130395.HEADER: Input/output error
/var/log/messages has the following to say:
Oct 11 11:05:38 aix kernel: [138537.991670] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved. Plaintext passthrough mode is not enabled; returning -EIO
Two questions:
- How do I fix this?
- How do I prevent this happening in the future?
I'm using Ubuntu 10.10.
