Using multiple screens crashes OpenMandriva regardless of version

[Frozen_Death_Knight]

Hello!

Requirements:

I have Searched the forum for my issue and found nothing related or helpful
I have checked the Resources category (Resources Index)
I have reviewed the Wiki for relevant information
I have read the the Release Notes and Errata

(Links do not work and I can’t log in)

OpenMandriva Lx version:

OpenMandriva Lx release 6.0 (Vanadium) Rock for x86_64

Desktop environment (KDE, LXQT…):

KDE

Description of the issue (screenshots if relevant):

PROBLEM:

• Using multiple screens with the OS black screens OMD on all versions when I use Wacoms Cintiqs.
• All of them take a long time to log with a black screen with a “_” in the top left corner of every screen.
• It then logs in and things work fine including extending the screen on the secondary screen.
• In about a minute or so OMD crashes and I have to reboot.
  SRemoving the additional screen from the equation keeps OMD completely stable.
  WORKAROUND:
• Plugging out the video component of the Cintiqs stabilises OMD. Same with using other types of screens that aren’t tablets, but that means having only one screen to run OMD.

Relevant informations (hardware involved, software version, logs or output…):

• Tried Rome, Rock, 6.0, etc. All of them have the same issue.
• Nvidia 580 driver. Previous testing also done on 565 and 570.
• Nvidia 3060 card.
• Wacom Cintiq 13" HD from 2013 and Wacom Cintiq 16 inch 2025 (only got this one last week). Drivers work fine when drawing since the tables have pen pressure and everything with zero issues to how they function.
• Same hardware is stable on Linux Mint 21-22 and Windows 10 with function.
• Tried Wayland and Xorg and the same issue happens with both.
• The rest of OMD works perfectly normal besides this one crash bug affecting multiple screens usage.
• Re-installed OMD several times with various installation methods.
• Crash happens regularly the moment I install Nvidia drivers on a fresh install.

Did you do those things, also? Because you didn’t really do the first:

@Frozen_Death_Knight

when I use Wacoms Cintiqs

Did you install the slim ISO’s?

What does this return?

I tried all available versions yes. Same issue across the board.

This is the byproduct of a server migration. @raphael is working on that.

Are you using the drivers from our non-free repo, or did you do something else like install them from nvidia or use the dkms package from the non-free repo? Is your card supported for the open driver?

Nvidia Open kernel module (Call for testing, ROME or Cooker)

Since the availability of the Open Source Linux kernel driver for nvidia, we have been interested in how it would work in OMLx, but have not had compatible cards to test it with. Based on recent guidance from the company, they will be suggesting this Open driver be the default: They did not include the compatible cards in this article, but the list is here: We package two versions of the proprietary and open drivers, one built with the installed kernel, and one with dkms. The latter is rec…

@zeroability All right! Odd that the links lead to there in that case.

Here is a full list of repos:

I experienced these things before I started using those repositories however. The main trigger for the crash happening is when I follow the recommended Welcome screen method of installing the Nvidia drivers. I was able to achieve this with fresh install with zero adjustments to anything besides installing the recommended Nvidia drivers.

As long as I do not install the Nvidia drivers the multiple screens work. If I install and reboot my PC the crash will consistently happen like I described in my original post.

I use an Nvidia 3060.

[Frozen_Death_Knight]

@zeroability Forgot to add, I actually posted in that thread at the start of the year with this:

It was a bit more stable, but I ended up with the same dead end. Perhaps it has improved since then?

[zeroability]

Don’t use Discover to manage repos. Use “Software Repository Selector” or om-welcome.

nvidia drivers a proprietary, even with the open kmod. There will be issues you may need to research, especially around hardware that not widely used.

@Frozen_Death_Knight

I use an Nvidia 3060.

It should be on the list, but you will want to read through the post. It’s informative and will have things you need to do.

Next time, just link the thread for brevity. No one can see the full context of the thread when you do that.

My apologies. Here you go!

Nvidia Open kernel module (Call for testing, ROME or Cooker)

The drivers are more stable than the standard ones on my end, but it is not saying much. I was actually able to log in to X11 with the open kernel without immediately getting a black screen, which is an improvement over getting a black screen immediately with no other choice but to remove the drivers with Timeshift. However, I am only able to log in for like a minute or so before I get a black screen that then throws me back to the login screen. Wayland doesn’t work at all and just throws me bac…

One common thing has been HDMI and sometimes hybrid video setups (intel + nvidia, etc). With your favorite search engine, you can find there are a lot of this issue happening:

https://presearch.com/search?q=nvidia+3060+black+screen+linux

Per the testing thread (and just in general), nvidia users have to be prepared to comb through nvidia’s forums (and other forums) to get some information for us to help. This is because, the code is closed source. We will need some logs with journalctl and possibly with x11 or wayland. Cooker (and soon ROME) with have xlibre and that seems to have its own challenges with nvidia (which there may only be one tester to see if their fixes for that work).

[Frozen_Death_Knight]

I just tried the drivers in that thread you sent and those crashed as well. Been trying to reach out to Nvidia as well about the crashes earlier this year. We’ll see if those drivers become more stable at some point.

[Frozen_Death_Knight]

Okay! I’ll try that over the weekend once I have more time. Thanks for tip!

[zeroability]

Try it without the exotic hardware, and see if it works. Maybe try hotplugging it and see if it works. There may be a config that needs to be made for the resolutions to work. It sounds like an out of range issue and the graphics server just gives up. We would know more with logs.
