Crashed updating 22.04 and nothing works correctly. Tried "sudo dkpg --configure -a" but still says read only file.

My operating system is jellyfish. Beyond that I can follow instructions, but I am not knowledgeable on Linux. Wiser people than I has provided me my various versions of Linux over the past 30 years. I avoid Windows.

I had two problems, but Epson tech solved first one. Reoccurring problem, ET-4850 printer says on my screen "rendering complete", but does not print. How can I fix this problem? My earlier problem, the router signal was poor and disconnected. That's been fixed, but my tech didn't have Ubuntu knowledge.

I'm using a laptop connected to an external monitor. I often switch from dual-monitor setup to using only the external monitor, I disable the laptop's built-in display through the display settings and work with a single display. Later, when I enable the laptop display and return to a dual-monitor setup, Ubuntu doesn't retain the previous monitor arrangement. It remembers monitor placements when I suspend or shutdown my pc but fails when I disable built-in display and re-enable it.

Is there a way to make Ubuntu consistently remember monitor placement across display configuration changes?

Additional information:

• Ubuntu version: 26.04 LTS (Wayland)

• Kernel: 7.0.0-22-generic

• CPU: Ryzen 5 5660H

• GPU: GTX 1650M (HDMI wired to D-GPU)

I've tried on Ubuntu 26.04 and Xubuntu 26.04. I want it to work without a monitor. I had remote desktop working on Ubuntu 25.04 with a vga monitor, but changing to a vga dummy dongle caused the connection to fail. There was a lot on Google about problems with Wayland and I thought I could get around that with Xubuntu. But I've had no success with that either.

I just tried to upgrade my Ubuntu 24.04 LTS to the new 26.04 LTS and I'm getting

There is no development version of an LTS available.

I installed a openjdk-17 package using

sudo apt install openjdk-17

and I figured out that 3 different folders were made in the usr/lib/jvm directory.

I know that the java-17-openjdk-amd64 is the real one to use the jdk but I don't know why there are other folders.(java-1.17.0-openjdk-amd64 & openjdk-17)

java-1.17.0-openjdk-amd64

java-17-openjdk-amd64

openjdk-17

What's the difference among these folders?

After logging in at GDM, the screen goes black with only a movable mouse cursor about 5 seconds later. The desktop never appears. Pressing Ctrl+Alt+F1 returns me to the login screen. SSH access works fine throughout, so the machine itself is running.

What I've already confirmed and tried:

• nvidia-smi works; GPU is an RTX 3090, driver 595.71.05.
• The NVIDIA kernel module matches the running kernel: modinfo -F version nvidia = 595.71.05 on kernel 6.17.0-35-generic.
• Disabled Wayland in /etc/gdm3/custom.conf (WaylandEnable=false). Logs confirm the session now starts as X11: "Running GNOME Shell (using mutter 46.2) as a X11 window and compositing manager" and it reaches gnome-session-x11@ubuntu.target. Still black.
• nvidia-drm modeset is already Y.
• The GDM greeter itself previously crash-looped; clearing /var/lib/gdm3/.config fixed that, so the greeter is stable now — the black screen is only on the user session after login.
• Reinstalled and then fully purged + freshly reinstalled the driver via ubuntu-drivers install (DKMS rebuilt, initramfs and GRUB regenerated). Still black after reboot.
• gnome-shell and Xorg stay alive for minutes after login (no crash, no coredump). Session logs show only non-fatal warnings (gsd-media-keys audio assertions, libinput XIChangeProperty errors).
• This exact symptom has happened before and was resolved by reinstalling/changing the driver, but a plain reinstall did not fix it this time.

System details:

• Ubuntu 24.04 LTS, kernel 6.17.0-35-generic (also occurs on older kernels)
• GPU: NVIDIA GeForce RTX 3090
• Driver: nvidia-driver-595 (595.71.05), prebuilt linux-modules-nvidia-595 flavor (note: dkms status returns nothing for nvidia)
• Two LG 1080p monitors connected
• Disk at 91% full

Questions:

1. With X11 confirmed and the module matching the kernel, what else causes a black-screen-with-cursor on the user session specifically?
2. Could this be a libglvnd / GL vendor library misconfiguration? My Xorg log shows "GLX: Another vendor is already registered for screen 0".
3. How can I capture the real glxinfo -B OpenGL renderer of the live session? glxinfo over SSH fails with "Invalid MIT-MAGIC-COOKIE-1 key / unable to open display :0".

A couple of tips for posting it: attach your full /var/log/Xorg.0.log and the output of journalctl -b _UID=1000 (paste to a pastebin and link it), since people will want them. And if you can, do the fresh-user-account test I mentioned before posting and add the result — "a new user account has the same black screen" vs "a new user works fine" is the single most useful clue you can give them, and it's usually the first thing they'll ask.

That GLX: Another vendor is already registered line and the cookie-blocked glxinfo are the two threads most likely to lead an expert straight to the cause, so I've put them front and center.

This tablet belongs to 10 years ago :D

I just got a job and my manager gave me to updating this tablet to version which has Google Play Store instead of 1Mobile.
I can't find its rom or anything, thing are not going well. Is there anyone to help me, please?
Thanks,

Herkese merhaba,
Bu tablet 10 yıl öncesine ait :D

Yeni bir işe girdim ve müdürüm bana bu tableti 1Mobile yerine Google Play Store’un bulunduğu bir sürüme güncellemem için verdi. ROM’unu ya da başka bir şey bulamıyorum, işler pek yolunda gitmiyor. Bana yardım edebilecek kimse var mı?
Teşekkürler,

I tried to run the Software Updater and got an error and it said to try later, but it won't come up now. the problem seemed to be with Zoom. I had gotten the Zoom app from their website and went the snaps and installed it. It runs but when I to into those icons of installed programs and hit the Software Updater now, it doesn't even come up. I will post the picture of the error message from Ubuntu but I don't really know how to do it. Like it says to run the package manager from the right-click menu, but you have to have something to right-click on, what do you right-click to get that package manager?

Is there a way to fix it or should I just remove Zoom and forget it.

The problem: After suspend-resume, conky is positioned on the far right of monitor 1, not monitor 3.

Additional Info: If I then kill and restart conky, it is properly positioned at the far right of monitor 3. This issue started after the update from 24.04 to 26.04. Conky is positioned correctly after restart, just not suspend-resume.

System Info: Ubuntu 26.04 (7.0.0-22). conky 1.22.2. 3 monitors (left to right, 1: 2560x1440, 2: 2560x1440, 3: 1920x1200). Primary display is monitor 2 (so, I think position 0,0 is on monitor 2).

What I've tried: Too much time Googling and ChatGPTing. Too many changes to list here. All sorts of system-level and user-level resume scripts. Adding kills/delay/restart to scripts. Changes to conky script (adding xinerama head, different gaps, different alignments, etc).

conky.config part of conky script (.conkyrc):

How do I manage my libertine container, and also direct the libertine tweaker tool, along with the UT tweaker,as well, to get this all to at least run smoothly. This is on Ubuntu touch though, so my way of fixing it won't be like regular Ubuntu, on the House PC. These are my questions though, so far. I have Libre office Gimp, and VLC, all already there, and somehow pacman too, but he don't even pop up, although it's a tab, that did ceeate. All different monsters with different issues, but they need fixed and I'm at the end of my learning. Github didn't even exist when I learned to code,a dab. Never good, but operable, at best. All I needed, for me. Not a want. Gimp: comes up, but I have zero control over it, when it comes on, and it's the same way with the vlc, like I said pacman goes back to mainscreen upon calling,and Libre office has every single icon, but it's as if each were empty. They open, and shut right back. I need a 101 period,on libertine, but on Ubuntu Touch. It run's Libertine a dab different, from what I'm feeling like I'm gathering. If delete it all is the answer; well, I do have a calculator, and a pencil and paper. We'll sure empty the Libertine, if need be. Just lost again, is all. Please assist, if there is any help for me, or maybe at least this little ordeal, here. Thank's, in advance.

Recently had a friend help me switch from Windows 10 to Ubuntu 24.04.4 LTS.

Found myself struggling while filling out PDFs of scanned paper documents. On Windows, I used the free version of Adobe Acrobat. It has the option to format inserted text letter by letter into evenly spaced boxes, which is something a lot of these documents call for.

I can obviously kind of McGiver a similar result by inserting several spaces after each letter, incredibly clunky though.

Can someone recommend a PDF viewer and editor for Ubuntu that allows inserting text in this format?

I installed Ubuntu Server 24.04 on a Raspberry Pi 5 then, installed the ubuntu-mate-desktop, but the screen resolution did not recognize the 1280x1024 resolution of the old Princeton monitor and reverted to a maximum resolution of 1024x768. I could set it with xrandr, but the setting was not permanent across a reboot.

I have installed the server on VirtualBox and allocated 2 vCPUs and 4096MB base memory.

So if I run free -h the output tells me 3.3Gi total, 499Mi used, and 2.3Gi free. Also 700Mi buff/cache and 2.8Gi available:

               total        used        free      shared  buff/cache   available
Mem:           3.3Gi       499Mi       2.3Gi       1.2Mi       700Mi       2.8Gi
Swap:             0B          0B          0B

The same thing can be confirmed by using top.

However the story changes when I use htop instead. Memory is shown at 276M used out of 3.3G, much lower than the previous reports:

Why is this? I haven't changed any of VirtualBox's advanced settings and only used the unattended install with automatic download of Guest Additions, as well as the CPU & RAM allocations aforementioned.

Since a couple of versions, my email folders are not sorted alphabetically anymore:

A search told me that I should have a command to automatically sort them out, but there is not such option on my version.

I thought I could sort the folders manually and place them properly sorted. Alas, it is not working. I am unable to move one folder relative to another. (that could be a personal problem, though...).

Could you please tell me how to sort them properly ? Many thanks in advance for your help.

Note: I thought they are sorted by creation time but, no, they are not.

Since the 26.04 kubuntu upgrade, when I try to log in with ssh using a password, I get a graphical window box asking for the password. I cannot emphasize enough how much I do not want this.

So I disabled the use kdewallet in the system settings, but that wasn't enough. I saw I also had to remove ksshaskpass, which I did, only to receive ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory, so I installed ssh-askpass and now there is a lame looking box asking for a password. Neither of those boxes work, and worse of all they break the use of sshpass which I need in some scripts. Yes, I know "use keys", but I can't on some systems, it's not allowed, don't ask me why.

So, how do I get ssh to ask for the password in text, as is traditional ?

I have been using Ubuntu and Windows without issues on a dual boot setup. The Windows drive mounts automatically on startup in Ubuntu, however I want to re-enable BitLocker to encrypt the Windows drive. After re-enabling it, Ubuntu will not start. I get the following message:

You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, or "exit" to continue bootup. Press Enter for system maintenance (or press Control-D to continue):

If I type systemctl reboot nothing happens. If I type exit the same message appears again.

I have disabled Bitlocker again, but still I would prefer to have the Windows drive encrypted because it is a laptop I sometimes travel with.

The entry for the Windows partition in the /etc/fstab file is:

/dev/disk/by-uuid/78EE-D15A /boot/efi vfat defaults 0 1
/swap.img   none    swap    sw  0   0

GNOME Activities Overview workspace thumbnails begin flickering after several hours of uptime on Ubuntu 26.04 LTS with GNOME Shell 50.1 running on Wayland and Intel Alder Lake-N integrated graphics (i915 driver).

System:

• Ubuntu 26.04 (upgraded from 24.04)
• GNOME Shell 50.1 / Mutter 50.1
• Wayland session (no Xorg session available)
• Intel Alder Lake-N UHD Graphics (i915 driver)
• Three displays (all 1920×1080 @ 60Hz)

Symptoms:

• After several hours of uptime, GNOME Activities Overview becomes visually corrupted.
• Specifically, workspace thumbnails flicker immediately upon entering Overview (Super key or hot corner).
• The flickering is limited to Overview workspace thumbnails and GNOME top bar. Normal desktop, application windows remain stable and unaffected.
• Exiting Overview immediately returns the desktop to normal. Logging out and back in resolves the issue temporarily, but it returns in minutes, rebooting it returns after several hours. No GPU resets, hangs, or DRM errors appear in journalctl.

I’ve tried:

• Kernel parameter: intel_idle.max_cstate=1 Appears to delay or partially change the symptoms, but the issue still occurs.
• Kernel parameter: i915.enable_dc=0 Initially seemed to reduce symptoms, but the issue still returned.
• Tested different kernels (including older kernel) No change in long-term behavior.
• Disabled a couple of third-party GNOME extensions (still using default Ubuntu extensions).

Observations:

• The issue does not affect application rendering or the desktop outside of Activities Overview.
• It appears only after extended uptime (hours), not immediately after login.
• The issue is reproducible across reboots and kernel versions.
• No relevant errors in journalctl related to i915, DRM, or GPU resets.

Question:

Has anyone seen GNOME Activities Overview workspace thumbnail flickering or corruption on GNOME Shell 50 / Mutter 50 under Wayland, particularly on Intel integrated graphics? Are there known issues, workarounds, or logs that I should investigate further?

Update:

I performed additional testing and found a significant correlation with monitor configuration.

With my original multi-monitor setup (2 ASUS monitors + 1 TCL TV), GNOME Shell produced thousands of repeated errors:

gbm_surface_lock_front_buffer failed Failed to query buffer age, got error 3003

These sessions also exhibited Activities Overview flickering, top-panel flickering, and occasional window-edge artifacts.

I have now tested the system with a single display only (different display: Sony TV over HDMI) and the issue has not reproduced. There is no visible flickering, no rendering corruption, and:

journalctl -b | grep -c "gbm_surface_lock_front_buffer failed" 0

journalctl -b | grep -c "Failed to query buffer age" 0

The issue also reproduced across multiple kernels, including a newer mainline kernel Linux 7.0.12-070012-generic, which makes a pure kernel/i915 explanation seem less likely. Using this mainline kernel the symptoms also started appearing after roughly 10 minutes rather than a few hours.

At this point, the strongest lead appears to be a GNOME Shell/Mutter multi-monitor rendering issue, or an interaction involving multiple outputs.

Starting around May 13-20, 2026, every time I wake my Ubuntu 24.04 machine from sleep or log in after a restart, I have to enter my password 2-3 times before it finally accepts it. The login screen seems to accept it, then immediately re-prompts. It's been consistent ever since.

Looking at the logs, I see this on every login:

gdm-password: gkr-pam: unable to locate daemon control file

gdm-password: gkr-pam: stashed password to try later in open session

I found some older Ask Ubuntu answers about this (How to solve: gkr-pam: unable to locate daemon control file? The login keyring did not get unlocked when you logged into your computer), but they're from 2010-2020 and mostly suggest PAM config tweaks that feel outdated. Has anyone else hit this recently? Any modern solutions?

I have sleep and resume problem on my Ubuntu Studio PC since Ubuntu 24.10. After I upgrade to Ubuntu 25.04 the problem still persist. Whenever the PC sleep, it can't resume. It's so laggy and unusable. I use Ubuntu Studio 25.04 with NVIDIA 570 driver in Wayland. Even Kernel upgrades didn't help sometimes. Is there anyway to fix this problem/issue?

original question/answer on r/ubuntu: Finally Solved My Ubuntu 25.04 Sleep / Resume Problem

Expected Sleep/Resume to work without issues but mostly my external monitor refuses to display and sometime it causes Wayland/Gnome to crash leaving me with option but to reboot. Sometimes i tried to go into terminal mode using ctrl+alt+F1 but equally didn't work.

On Ubuntu 22.04 over windows (WSL) when I try to run node I get the error:

And when it didn't help to completely uninstall it and npm and install them fresh.

running file on the file gives the same result as running it on ls which works.

I want help to

• make Ubuntu 'update && upgrade' itself automatically,
• select the settings for this automatic system.

How can I do it? Please advice about

• where to find the menu (GUI) or file (command line) to do it,
• what settings that can be recommended (if different from the default).

As a bonus, please describe how different types of program packages are treated,

• program packages from Ubuntu repositories and PPAs
• snap packages
• flatpak packages
• other kinds of programs/packages.

I put systemd-resolved into debug mode trying to troubleshoot high number of DNS queries from this machine (tcfe01). It seems systemd-resolved is keeping multiple copies of cache, one for global scope (*/*) and another for particular network device (eno1/*). From the logs it seems only global scope (*/*) gets cached but not (eno1/*). For first query we see Cache miss for both scopes, but for subsequent queries we get Positive cache hit for global scope, but Cache miss again for device scope and we end up hitting the DNS server every single time.

This defeats the whole purpose of having the cache, not only hurting the performance on local machine (tcfe01) but also unnecessarily hammering the DNS server. Any insight into this behavior would be very helpful.

I am trying to use GPU with Tensorflow, so I installed CUDA 10.1, CUNN 7.6, TensorRT 6, and Tensorflow-GPU 2.1.0. But when I import tensorflow to check if it can detect the gpu. it gives me the following error

>>> import tensorflow as tf

Can you tell me how can I get the missing libraries please?

Thank you Hadeel

I tried to run resize 40 80 to change my terminal display and got the following error:

Can't set window size under VT100 emulation

Can anyone explain what causes this issue and how to bypass?

I've done it before but I had to re-purposed that USB drive and I can't seem to figure out how I got ddrescue installed the first time around. Which file do I need from here http://ftp.gnu.org/gnu/ddrescue/ and, once copied to my bootable thumb drive, how can I install it so I can access it via terminal?

I'm new to Linux so I need step by step if possible.

Using a fresh install 17.04 lUbuntu

Fairly new to Ubuntu and as often is my problem any help I try to find is way more advanced than I can follow.

I'm trying to use test my AMD R9 290 card for mining using Genoils miner. I tried it on Windows before installing Ubuntu and that worked fine.

The problem is when I try to get it working I get this error:

[OPENCL]:No OpenCL platforms found
[OPENCL]:
Listing OpenCL devices.
FORMAT: [deviceID] deviceName

I know at least some OpenCL related packages are installed.

As I understand it I should use an open source driver called AMDGPU instead of AMD's driver. But I can't figure out if it's already installed or if not how to install it. The AMDGPU page mentions some xf86-video-amdgpu that I get "unable to locate" on.

I tried AMD's own proprietary driver and with that installed OpenCL works but I then get an error that i have the wrong DRM version: "amdgpu_device_initialize: DRM version is 2.45.0 but this driver is only compatible with 3.x.x." As I understand it AMDGPU uses 3.x.x while AMD's own driver uses 2.x.x.

So from what I've found out you can use this command to check if you're using the open source AMDGPU

lspci -nnk | grep -iA2 vga

If the kernel driver in use says "radeon" rather than "fglrx" it's using AMDGPU.

I blacklisted AMD's driver using the instrucitons on the AMDGPU page:

/etc/modprobe.d/radeon.conf

blacklist radeon

(Although I find it a bit odd that it here should say "blacklist radeon" while the kernel driver (using the command above) should report "radeon" with AMDGPU)

Anyway I was still unable to get it to work with OpenCL. OpenCL still reported no devices. From what I've learned this seems to be because many things including OpenCL aren't fully supported on newer Ubuntu versions like my 17.04. Best might be Ubuntu 14 for this.

In the end I took the easy way out and installed Windows 10 using an old key :f When I get some more time I will try again using an old Ubuntu release and see if I can get it working.

Can anyone offer advice on a program for compiling and publishing a book?

I have Scribus but am having a rough time with it. I was very good with Quark... I need something that has style sheets, page numbers, contents.

If Scribus is the best for those purposes, I guess I'll have to keep working with it but as of now I really hate it.

I'd like to create a Windows bootable USB stick, but I don't have a Windows machine at the moment to do so. How can I achieve that using Ubuntu?
