Good day to everybody.

I have dual system computer with Windows 10 and Ubuntu 24.04.4 LTS with added KDE Plasma (installed by "kubuntu-desktop"). The computer has embedded (Intel® HD) and external videocard (NV108), the latter was used when installing Linux. The computer has worked fine until recently.

Yesterday I changed monitor to another one (with bigger diagonal) and mistakenly connected it to embedded graphics. Working with Linux was ok and GRUB menu was visible and allowed to select a system, but Windows ceased to work, it showed empty desktop, the mouse and the keyboard didn't react in Windows either (while worked in both Linux environments).

I realized that I had used wrong video output and changed it to external.

The first anomaly was that GRUB menu disappeared, but Windows started to work perfectly (it is indicated in GRUB_DEFAULT and starts due to GRUB_TIMEOUT). GRUB_TIMEOUT_STYLE is menu, so the menu must appear. Then I tried Linux, with the result that GNOME (default Ubuntu) desktop works normally, but Plasma desktop behaves as Windows formerly - empty desktop, the mouse and the keyboard do not react.

I tried "--reinstall kubuntu-desktop", but nothing changed.

I assume that problem may be associated with monitor, as the monitor is the piece of hardware that changed, but strangely that GRUB shows menu only while embedded videocard is used (so it must be tied with Plasma desktop that doesn't work either).

Would be grateful for any helpful suggestions to fix the problem.

initramfs_alert_uuid

available kernets

I can't do much on busybox / initramfs because listing the partions / blocks returns nothing (I tested the ls /dev/sd* /dev/nvme* /dev/vd* 2>/dev/null I saw from this post

Some ending when starting on kernel 6.17.0-23-generic in recovery mode. Happily, kernel 6.17.0-22-generic still works (this is what I am currently using to write this post)

Can someone help me ?

What I did before getting this error : (I think) I was able to work on kernel 6.17.0-23-generic at least one time. But got some troubles to have my laptop HDMI output working. However, the HDMI on my USBC hub was working. So I decided to change the driver from X.org to NVIDIA driver 595-open. Reboot was needed, and since, I have this error message. Using older kernel 6.17.0-22-generic, I switched back to Xorg, but does not solved my initramfs alert.

I booted to my windows boot, to perform some update (included a lot of DELL bios updates) after getting this error. Still did not magically solved my error.

Since updating to Ubuntu 26.04 on my laptop, I've been having an issue where the screen just goes black after Ubuntu boots up. I see the boot animation, but as soon as I reach the login screen, the screen goes black. When I connect a second monitor, I can see that everything works fine on it. I’ve already found a workaround to reactivate the primary screen: if I briefly close the laptop and then open it again, everything suddenly works as it should. I generated a GPU log of the startup. You can see that after 9 seconds, the graphics card tries to communicate with the screen and apparently fails. A clean install did not fix the problem. Does anyone have any idea how to fix this?

I am planning a dual-boot installation of Ubuntu 26.04 LTS alongside Windows 11 on an ASUS ZenBook 14 UM425UA (AMD Ryzen 5 5500U with Radeon Graphics, 16GB LPDDR4X, 512GB NVMe SSD).

I currently have 160 GB of free space available. I plan to allocate approximately 60 GB for Ubuntu initially, using the Windows drive for documents, active projects, etc. After making sure I no longer need to rely on Windows for work, I will remove Windows completely and expand Ubuntu to use the full disk.

I have read tutorials on dual-boot installation (such as this one and this one) that recommend using the "Install alongside Windows" option in the Ubuntu installer, since it is simpler and carries lower risk during installation. If I understand it correctly, the installer will create a single partition (/), instead of two different partitions for root and home.

However, given that my goal is to remove Windows and expand Ubuntu to use the entire disk, could having Ubuntu on a single partition create complications in the future? Does having a separate /home partition significantly reduce the risk when deleting the Windows partition later? I have read about the need to move the root partition to place it adjacent to the empty space left by Windows, before resizing it to fill the gap, which cannot be done from within Ubuntu but only from a live USB. Isn't this operation risky enough to justify the complexity of manual partitioning now, during Ubuntu installation?

Which installation strategy (automatic vs. manual with separate /home) provides the safest and most convenient path for that future migration from dual-boot to Ubuntu-only?

Any insights would be greatly appraciated. Thanks!

I followed the "Getting started" instruction at [https://github.com/intel/systemc-compiler/wiki/Getting-started] to install ICSC using install.sh (1st method), but it could only compile about %22 and the compilation process terminated.

Here is my system setting: g++ (Ubuntu 13.3.0-6ubuntu2~24.04.1) 13.3.0 cmake version 3.28.3 git version 2.43.0

Ubuntu Description: Ubuntu 24.04.1 LTS

I also tried to use Ubuntu 22.04, I got errors too.

Has anybody tried to use Windows Subsystem for this installation?

Happy Sunday everyone!

A fresh install of 26.04 is working brilliantly, and the CPU and GPU-related improvements are proving to be a welcome speed/quality upgrade to my system. However...

I use the default [Rygel] media sharing to watch videos on my TV simply by dropping them into my Videos folder on Ubuntu, and it was working fine in 24.04. However, I noticed that since my fresh install of 26.04 my .mkv videos are no longer served and do not appear in VLC local network discovery on both my TV and mobile.

The root cause is Gstreamer, which Rygel uses, unable to decipher .mkv files anymore; all other formats, e.g. MP4, are fine and I can see and play them. The error comes up as either 'unsupported pixel format' or 'failed to configure the buffer pool' depending which .mkv file I try. In case this problem was Rygel-specific, I installed the [now default] Showtime app, which is also Gstreamer-based, and sure enough, that comes back with 'unable to play video' on .mkv files with the detailed error being Gstreamer with the same two errors as above.

Please could someone confirm this bug for me? The easiest way is just to try to play any .mkv video using Showtime. I have restricted extras installed and all other codec/video libraries including good, bad and ugly. It would be interesting to hear from someone who does not have my ARM-based (Raspberry Pi 5) system to make sure it is not specific to the RPi5-specific build of 26.04.

Many thanks in advance

Nick

Ran into this today, could not get Teamviewer to run in 26.04.

How can I get this to work??

Two days ago I ran “apt upgrade” on a Ubuntu 24.04 machine to get a kernel update, and as usual a reboot was suggested. However, the machine (in a data center far away) did not come back up, and using a remote console I found out that GRUB seems to have some kind of issue:

<- this is supposed to be an inline image: https://imgur.com/a/X6vrel0

GNU GRUB  version 2.12

Minimal BASH-like line editing is supported. For the first word, TAB
lists possible command completions. Anywhere else TAB lists possible
device or file completions. To enable less(1)-like paging, "set
pager=1". ESC exits at any time.

grub> set pager=1
grub> lsmod
error: unknown filesystem
grub> ls
error: unknown filesystem
grub> lspci
error: unknown filesystem
grub> _

How did an “apt upgrade” get my GRUB into a state where it cannot even perform an “ls?” And more important, how do I get GRUB out of that state?

(This question clearly differs from Grub rescue - error: unknown filesystem, in that whatever is going on in this question can obviously not be solved by running “ls” because, as shown above, only an error message is displayed, as reaction to many basic GRUB commands, except set, insmod, and recordfail. I’ve tried recreating the steps that grub.cfg lists for the default “Ubuntu” menu entry, but everything that’s not an insmod gets met with “error: unknown filesystem”. I’m not sure how to proceed from here.)

This answer recommends using GRUB’s auto-completion to list stuff, and I can indeed get GRUB to list partitions of the installed disks:

grub> ls (hd0,
Possible partitions are:

    Partition hd0,gpt1: No known filesystem detected - Partition start at 2048KiB - Total size 33554432KiB
    Partition hd0,gpt2: No known filesystem detected - Partition start at 33556480KiB - Total size 1048576KiB
    Partition hd0,gpt3: No known filesystem detected - Partition start at 34605056KiB - Total size 2111832064KiB
    Partition hd0,gpt4: No known filesystem detected - Partition start at 2146437120KiB - Total size 1760581447.5KiB
    Partition hd0,gpt5: No known filesystem detected - Partition start at 1024KiB - Total size 1024KiB

grub> ls (hd0,gpt

The ext2 module has been inserted, but GRUB still does not recognize the filesystems on any of the partitions, and at least three of them it should recognize! hd0,2 is /boot, which is ext3 (I think?), and hd0,3 and hd0,4 are / and /home, respectively, which are also ext3 or ext4. (I honestly don’t care, as it should be irrelevant here. Relevant is that GRUB should be able to recognize the filesystems, as GRUB can handle all of them.) Just as before, running the actual ls command results in “error: unknown filesystem”.

I attempted to update some ppa by typing: sudo apt update and I got the following errors:

I checked at Canonical and Ubuntu Status (https://status.canonical.com) and saw the message:

I just want to know when ppa.launchpadcontent.net will be working?

I'm having a problem with Ubuntu 26.04 LTS. After updating from 25.10, it started freezing, meaning it runs for about 10 seconds and then freezes for about 0.5 seconds. I watch YouTube and it freezes regularly. I do a speed test on the website, and it freezes for 0.5 sec after around 5-10 sec. I play on Steam and it freezes, but I can hear that the graphics card isn't working at the moment—it doesn't make the same noises it normally does. When watching YouTube or running speed tests on the website, the CPU temperature is a maximum of 70 degrees Celsius, and the GPU is 30 degrees Celsius. Everything works fine except for the freezing. My question is, how can I approach this? How can I diagnose the problem? Or what could be the cause?

Command result:

Does anyone have the driver for the Mediatek 7902 wireless adapter? I can't use WiFi and I really like this OS.

I am a newbie linux user and I know fairly almost nothing but i've been managing to fix things as I go.

Since yesterday a problem has been going on for me, when I tried playing a browser game on vivaldi, a pop up appears saying WEBGL2 is missing or required, and tells me to update my system or browser, I tried again on Falkon, and the same issue appeared, so today i've updated my system and the issue still persists, I also upgraded my browsers but that doesn't seem to have helped either.

From what I understood it could be related to Nvidea drivers, as far as i'm aware i'm using Noveau, I believe I was having problems earlier on when I had just downloaded ubuntu with the Nvidea drivers so i've switched to Noveau.

I'm on Ubuntu 24. 04. 4 LTS, using xserver-xorg-video-nouveau

I have not used Linux before, I have used Freebsd as a VM - a novice however. I also have other windows OS running as VM so no stranger to Hyper-V. Host machine is AMD Ryzen 5, 32G RAM, Graphics is AMD Radeon Graphics. Host OS is Windows 11 Pro build 26200.8328 I have installed Ubuntu 26.04 as a VM and am able to log into machine with normal login. I try to log in using "Enhanced session" and the window changes to virtual machine connection and a Xrdp login prompt. Session is preselected to Xorg, other options on the drop down box are XVnc, vnc-any, neutrinordp-any. All options fail with same error. I enter my username on the prompt, enter my password and "OK" after a short time the window shows black with white writing error message "Video remoting was disconnected", I then get another splash screen on top of that message from the MS Hyper-v Virtual Machine Connection saying "The session was disconnected. If you want to continue, try to connect again. If the problem persists, contact your system administrator. Would you like to reconnect? " Is anyone able to suggest to me what the problem is and how to fix this so I have a GUI in enhanced session. Are there logs I can copy and show here to help sort this out?
thank you in anticipation.

I didn't have Remmina installed previously. It isn't in the snap list and when I run the Ubuntu software app and search Remmina, it doesn't recognize that it's already installed so I can't remove it. Is this app required for updating or support? I uninstalled from the command line but I'm wondering why the Ubuntu software doesn't recognize it and how it got there in the first place. There were several files and folders listed in different directories related to remmina. Now there are two empty folders - org.remmina.Remmina and remmina - in my .cache. Best way to remove them?

i created directories using crontab but don't know how to delete them there are so many and they all start with dir(random numbers),I cant use rmdir bcs i dont know which option i should use (im using ubuntu ) the crontab command i used is :

crontab -e
 ***** mkdir /home/name/dir$(date +/%N)

i use this ubuntu version : 4.4.20(1)-release

Não consigo instalar o repositório ppa da impressora canon ip1800 no xubuntu 21.04 LTS, dá um erro no terminal ao colocar os seguintes comandos:

sudo add-apt-repository ppa:thierry-f/fork-michael-gruz

I recently upgraded to Ubuntu 26.04 (Kernel 7.0) on my Lenovo IdeaPad Slim 5 15ARP10 (model 83J3) and had no sound from the internal speakers. Bluetooth audio worked fine though. The problem: The Conexant SN6140 audio chip is recognized by Linux (aplay -l shows it), but PipeWire never properly initializes the speaker output on boot. The speaker port shows “availability unknown” and no sink is created for it.

I am unable to open the software and update to upgrade the system. I get the following message when I try to update in the terminal: N: Ignoring file 'third-party.sources.save.1' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

E: Malformed entry 1 in sources file /etc/apt/sources.list.d/third-party.sources (URI parse)

E: The list of sources could not be read.

How can I get into the update?

Any ideas why this tab is constantly crashing ? https://www.icloud.com/mail/

I maintain various tabs with my email addresses open so I can check for emails. They are stable, but the address above keeps crashing.

Ubuntu version 24.04.4 LTS

when my Lenovo x390 laptop suspends it won't wake again. Pushing the power button results in the fan turning on but the screen remains black and the power button lights slowly on and off showing that the system is in suspended mode.

Troubleshooting the issue I was booting the system from a ubuntu 24 LTS live-usb. The same problem occurs.

What may be the problem, what can I do?

Best regards, Joachim

I have tried to visit the official Ubuntu website, but it seems to fail with 503. Can anyone share any information they might know about this issue?

Question

I am running Ubuntu 25.10 (Plucky Puffin) on an Asus laptop using the MediaTek MT7902 Wi-Fi card. Out of the box, the wireless interface is not detected.

Hardware Details: lspci -nnk | grep -A 3 Network output:

02:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902]
    Subsystem: AzureWave Device [1a3b:5520]
    Kernel modules: mt7902

Despite the module being listed, the device is shown as UNCLAIMED.

Symptoms and attempted fixes:

1. Secure Boot Conflict: When I try to manually load the driver via sudo modprobe mt7902, I receive: modprobe: ERROR: could not insert 'mt7902': Key was rejected by service

2. Kernel Instability: On some boots, the system hangs or triggers a kernel panic during the hardware probe phase.

3. Firmware Logs: dmesg shows Loading of unsigned module is rejected and sometimes fails to locate specific .bin firmware files for the gen4 architecture.

How can I safely install a working driver for the MT7902 on Ubuntu 25.10 without causing boot loops or kernel panics?

I have a PDF with different page sizes, some of them landscape and some portrait. How do I make them all portrait?

I'm wondering if there's an easier way than going through each PDF page with pdfinfo -f <pagenum> -l <pagenum> and determining if it's, e.g., Page 135 size: 640.45 x 442 pts (portrait) or Page 1 size: 426.967 x 663 pts (landscape).

To run a program that is designed for internal use, it requires GLIBC_2.34. Ubuntu 20.04 is installed on the computer, where GLIBC_2.31 is available. How do I install GLIBC_2.34 on Ubuntu 20.04 or how do I use it for the program?

I installed ubuntu 24.04 on older Dell laptop (originally window 8) intel 3i processor. After the error (Failed to open \EFI\ubuntu - not found) it loads grub and then boots to ubuntu. Everything is fine until I go into the files of the OS. The computer locks up. Reference boot-info https://paste.ubuntu.com/p/rMMm7spNCf/. I ran boot repair with no change. I think the original UEFI is preventing a proper boot.

I have problems with the iwlwifi network driver, and I want to try upgrading it to the newest available version. On AskUbuntu, I found a suggestion to download a driver from https://wireless.wiki.kernel.org. I found a page there for the iwlwifi driver, at:

https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi?s[]=iwlwifi

My adapter is an Intel Wireless 3160. The "Firmware" section on the kernel.org page has multiple entries for the 3160 card for different kernels, e.g.:

• 3.10+ → iwlwifi-3160-ucode-22.1.7.0.tgz
• ...
• 4.1+ → iwlwifi-3160-ucode-25.30.13.0.tgz
• 4.3+ → iwlwifi-3160-ucode-16.242414.0.tgz

I'm on Ubuntu 16.04 LTS, checking the kernel version:

$ uname -a
Linux akavel-lenovo 4.4.0-137-generic #163-Ubuntu SMP Mon Sep 24 13:14:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

My kernel is 4.4 — so, which one of the above drivers should I choose? My first thought was to use the 4.3+ — but then I noticed the driver version is apparently 16.x, while 4.1+ has 25.x — so can I use the 4.1+? Is the driver really newer, or the ucode numbers mean something else? Or do I have to use the 4.3+? Or something else? I'm confused :( Or should I maybe just compile a driver on my own? If yes, then how? To add the confusion, the page also has a section like below (emphasis mine):

7260, 3160, 7265, 7265D, 3165 and 3168 support

Those devices will not be supported by the newest firmware versions: the last firmware that was released for 3160, 7260 and 7265 is -17.ucode. Bug fixes will be ported to -17.ucode.

Looking into the linux-firmware.git repository mentioned somewhere else on the page indeed seems to show an iwlwifi-3160-17.ucode as the one with the highest number. But when I downloaded the iwlwifi-3160-ucode-16.242414.0.tgz, it only has a iwlwifi-3160-16.ucode inside...

To summarize: the "Firmware" section on the wireless.wiki.kernel.org website is confusing to me, I don't really know which version should I download?

edit 1: Hm; after downloading the iwlwifi-3160-ucode-25.30.13.0.tgz and looking into it, it has an iwlwifi-3160-13.ucode file inside, so at least it seems to clear part of the confusion, in that the internal ordering follows the kernel version ordering, and I should probably just ignore the weird versioning in the tgz names. Still not sure what is it about the ucode-17 mentioned as the "newest version" but not being present in the newest tarball.

I just purchased a network adapter which according to the driver CD is a RT2870 (It isn't written on the adapter). I've installed other things using commands before but the instructions on the readme file that came with it are quite confusing.

Has anybody made this network adapter work successfully in Ubuntu? I'd really appreciate some simple step by step instructions of how to make this work.

I just don't know how to turn on my Wi-Fi or choose a Wi-Fi connection. I'm now using the cable, but I really need to use the Wi-Fi on school. How to do that?
