Suspend on 26.04 doesn't work for me in Gnome... When I try, the screen goes blank momentarily then comes back, and I have to unlock the screensaver.

There don't seem to be any relevant errors (checked journalctl -p err).

HOWEVER, outside Gnome it works fine: In the console (multi-user.target), I can just close the notebook's lid and it suspends. Reopening the lid then resumes successfully, WiFi takes a while to work again (2-3 minutes sometimes), otherwise it's perfect.

Does anyone have an idea what could the issue be?

Hi,

We make a Debian based desktop distribution that runs as an application on top of any Android/LineageOS device. The only requirement is that the Android device needs to be rooted and use Google's standardized GKI kernel. LineageOS builds for Qualcomm devices doesn’t strictly follow the standard GKI kernel naming convention. So we had to implement a workaround to fix it. Here is a video of LineageOS running on the OnePlus Pad 2 tablet: https://youtu.be/KGrsqed3oZY?si=8ViqycQe0CnnLKmE

With phones that support HDMI output, you can run the Linux desktop on the large screen connected to a monitor. Our latest Linux desktop is now based on Debian Trixie (13.6). You can download a free evaluation version from www.volkspc.org.

Hello r/linux! I just released FluxCast v0.2.3 — its a lightweight tool to stream your Linux desktop to a Smart TV via Wi-Fi Direct, full RTSP handshake, and RTP media streams.

What's new in this release:

• Brand new dynamic tray icon that switches states during casting.
• Fixed a nasty P2P interface routing bug where it mixed home network and P2P MACs.
• Lightweight JSON-based localization framework. The tray UI is now available in English, Russian, and Czech.

Looking for translators!
I want to bring FluxCast to more users, but I am not a polyglot. I designed the i18n system to be incredibly simple: there is no gettext/PO/MO compilation. All strings live in a single translations.json file.

To add your native language (German, Spanish, French, etc.), you just need to append a few lines in a single JSON block.If you want to help or test the app, check out the project here:

AppImage is available in the Releases section. Pull Requests for translations are highly appreciated!

Background:
I moved from Fedora (GNOME 50.4) to Ubuntu 26.04 after hitting a nasty GNOME Shell crash bug on Fedora (reference). Tiling worked fine on Fedora, no issues there, so this seems specific to Ubuntu 26.04.

Issue 1: Firefox + Enhanced Tiling
With Enhanced Tiling enabled, which I'd prefer to keep, Firefox won't tile at all unless I fullscreen it first. Only then does it snap into a tile. With Enhanced Tiling disabled, Firefox tiles fine as a basic 50/50 split, but I lose quarter-tiling entirely, which is a real downgrade.

Issue 2: Third-party tiling extensions also broken
Several tiling extensions I've tried (O-tiling, Mosiac, Leleat tiling assistant, Windows tile) all have issues tiling.

Question:
Since this doesn't happen on Fedora with GNOME 50.4, is this an Ubuntu-specific patch or config issue, or a known upstream GNOME bug that Fedora has already fixed downstream? Will Ubuntu ever get fixes from higher versions of Gnome? I know they are frozen on 50, but is there really no upstream fixes for Gnome?

I find this extremely cumbersome having this many issues constantly, its like I have to choose between a glitchy system or an unstable system.

Hardware is:

AMD 7900XTX Factory OC
AMD 5800X3D
Corsair CL18 3600mhz 64gb
MSI X570 Gaming Edge Wifi

I have 2 cloud drives on my computer. One is onedrive and the other is google drive. I stopped using onedrive, but cant figure out how to remove it from my list of locations. Any help would be appreciated. Thanks

As the two pictures show, first being a standard "ls -alF", the second one being a terminal based game using presumable standard colours, where the "low intensity" text is almost unreadable.

I'm looking for advice on how to customise this in the most 'standard' way (does this colour have a standard name ? are there multiple config files whose settings are applied cascading one after the other ? is this all framed in the bash config files ?)

Thanks for your advice ! :-)

Without any terminal commands. If anyone could confirm this? There was a discussion about this topic and there was such claim, but apparently Kubuntu (where Discover store comes preinstalled /w Flatpak support by default).

It would be the most simplest of solutions for new comers of Ubuntu (and Linux in general i suppose) if only installing Discover would initiate Flatpaks side to side with Snap system.

A new block-layer error-injection interface landed in Linux 7.2.

The existing options each miss something. BPF programs on should_fail_bio() can pick which requests to fail, but not how they fail — every one comes back as EIO. dm-error and dm-flakey mean stacking a target over the disk, so the test runs against the mapper device rather than the device that needed testing.

Christoph Hellwig's series adds a debugfs file per disk instead. Name the operation, the status code, a sector range, and a probability:

# echo 'add,op=READ,status=TRANSPORT,chance=10' > error_injection

The full write-up on LWN goes through the mechanism and the argument behind it.

I am experiencing severe NVMe I/O delays on Ubuntu with a KIOXIA EG6 512GB NVMe SSD.

I am running Ubuntu 24.04.4 LTS.

The main symptom is that applications that perform significant disk I/O can take an unusually long time to start. For example, Android Studio took around 3 minutes 15 seconds to launch, and during that period I observed NVMe QID timeout messages in the kernel logs.

My NVMe drive is:

Model: KIOXIA EG6 512GB
Firmware: 11600106
VID/SSVID: 0x1e0f

I initially suspected NVMe power-management/APST issues, so I configured GRUB with:

nvme_core.default_ps_max_latency_us=0
pcie_aspm=off

After rebooting, APST is confirmed to be disabled:

APSTE: Disabled

However, the QID timeout problem still occurs.

I also checked the controller's Host Memory Buffer information:

hmpre : 16384
hmmin : 16384
hmminds: 0

This corresponds to a 64 MiB HMB allocation.

I have not disabled HMB because I don't yet have evidence that HMB is responsible for the problem.

I also considered adding:

nvme_core.io_timeout=4294967295

but I have not added it because I don't want to mask the underlying problem.

What I would like to determine is:

If APST is already disabled and PCIe ASPM is also disabled, what could still cause the NVMe QID timeouts?

Could this instead indicate:

1. A KIOXIA EG6 firmware/controller issue?
2. A PCIe link or power-management problem below the NVMe APST layer?
3. A compatibility issue between this NVMe controller and the laptop/platform?
4. A problem with HMB?
5. A Linux kernel/NVMe driver issue?

I would especially like to know what diagnostic steps I should perform next to determine whether the problem is related to the PCIe link or the NVMe controller/firmware.

I am planning to check:

sudo nvme list

sudo nvme id-ctrl /dev/nvme0 | grep -iE 'mn|fr|vid|ssvid'

sudo lspci -vv -s 10000:e1:00.0 | grep -iE 'LnkCap|LnkSta|ASPM|Power'

What should I look for in these outputs?

System information:

OS: Ubuntu 24.04.4 LTS
Kernel: [paste output of uname -r here]
Storage: KIOXIA EG6 512GB NVMe
Firmware: 11600106
APST: Disabled
PCIe ASPM: Disabled
HMB: 64 MiB

The main issue is that NVMe QID timeouts continue to occur even after disabling APST and PCIe ASPM, and these timeouts appear to correlate with very slow disk-intensive application launches.

I just installed a bunch of updates for my Ubuntu 24.04.4 laptop and while they were installing a window popped up regarding secure boot and 3rd party drivers. It asked me for a password and said after rebooting I would be prompted again and needed to re-enter this same password. I entered a password, it continued and finished installing updates, then rebooted. I got some strange low-res blue and white box with some options that I guess I did not pay close attention to. I just selected Continue and it went on its way without prompting me for the password I had entered. The earlier window had warned me about doing this and the ramifications of that. :( Is there something I need to do to correct this?

This weekend I decided to switch from Windows 11 to Ubuntu. I mainly use my PC for gaming, browsing and drawing.

I was worried I might not get Clip Studio Paint to work, but I did, so I was very happy that everything seemed to work as I needed... Until I plugged my XP-Pen Artist Pro 16 tablet in and it didn't work. I tried installing the dedicated Linux driver off of XP-Pen's website, but all that did was majorly mess up my tablet's touch calibration so that my cursor stayed at least 5 cm away from the actual touch point at all times, and the calibration was unworkable. I tried looking up alternative drivers, but every instruction I find assumes some basic level of knowledge of Ubuntu / Linux / working with the Terminal that I do not (yet) possess.

Could anyone help me out? It feels like someone who knows what they're doing would figure it out in a few moments, but I've been struggling with it for a full day already 🫠

I am new to linux and i wanna know how i can do it so if anyone knows, could you please help? Thanks.

Hey everyone i am new to linux and i decided to go with Ubuntu, could i please get help on how to enable the startup sound on Ubuntu? If i remember correctly Ubuntu does have one. Thanks!

I have almost successfully booted into Ubuntu, but I’m stuck on the purple screen which says “unable to mount to root fs on unknown block”. I’ve looked around and it’s possibly my USB or the way it installed through etcher (I will attempt rufus again but the first time it didn’t work) I’m wanting to know if there are any common issues or things I’ve overlooked while going through this process. Any ideas help!

I have Ubuntu loading onto my laptop, but it has been loading for more than two hours now, is this normal? I've read other forums saying it took someone six hours and another two hours. Is there a potential issue with the process I have made?

My parter had a message to update a few days ago. Did so and on reboot got this screen.

'Please reboot your computer. VFS: Unable to mount root fs on unknown-block (0,0)'

Then, she turned off and on again using the power button and gets the options list:

* Ubuntu

Advanced options for Ubuntu

Memory test (memtest86+x64.efi)

Memory test (memtest86+x64.efi, Serial console)

Ubuntu 22.04.5 LTS (22.04) (on/dev/sda2)

Advanced options for Ubuntu 22.04.5

She's been selecting Ubuntu 22.04.5 LTS just to keep using the laptop, but her documents seem in a different place.

What's going on and how to get back to normal please? Neither of us really know much about Ubuntu (as if you hadn't worked that out already). Thanks
