Description Brian Rockwell 2020-04-24 19:36:13 CEST
Description of problem: Computer started experiencing screen dithering and artifacts after upgrade to Kernel 5.6.6-1.  This uses the Nouveau display driver.



Version-Release number of selected component (if applicable): 5.6.6-1  Kernel-Server-latest.i686

Hardware:

Video:  Vendor: ‎NVIDIA Corporation
Description: ‎C51 [GeForce 6150 LE]
Media class: ‎VGA compatible controller

$ uname -a
Linux localhost 5.6.6-server-1.mga7 #1 SMP Tue Apr 21 22:45:17 UTC 2020 i686 i686 i386 GNU/Linux


Boot Parameters:  noapic splash quiet noiswmd resume=UUID=afd38e0c-b4a5-46b9-bbc5-a3ed905b66b4 audit=0


How reproducible:  system starts dithering on the desktop after moving the mouse over different parts of the screen.  

this also happens in LibreOffice Writer.  It does not happen in Firefox.

Comment 8 Morgan Leijström 2020-04-29 21:48:24 CEST
Meh!
Just a few minutes after posting that the desktop froze.
That was while changing desktop i think, i have four, with different programs.  One physical screen.  It froze while everything was semi-translucent.
I could move the mouse, but nothing responded, not even Ctrl-Alt-F3, nor clrl-del-del or ctrl-bkspc-bkspc.  Had to pull plug after some waiting.

Now on next boot:

# journalctl -b-1 | grep nouveau

Comment 9 Morgan Leijström 2020-04-30 08:19:02 CEST
Tried to stress it to recreate that problem but, no.

Got another nouveau line in log though:

apr 29 22:21:32 svarten.tribun kernel: nouveau 0000:01:00.0: DRM: core notifier timeout

But no visual problem.


Same line appeared after unlock of screensaver, and the desktop shold appear from faded, but flickered instead.  Switching desktops, it hung temporarily but this tim i could just waut a few swconds, and try again and it is back.  New line in log:

apr 30 08:10:22 svarten.tribun kwin_x11[6412]: qt.qpa.xcb: Unhandled client message:  "_NET_CURRENT_DESKTOP"

Can nvidia be interfering?  Now uninstalling nvidia:
- dkms-nvidia-current-430.64-8.mga7.nonfree.x86_64
- nvidia-current-cuda-opencl-430.64-8.mga7.nonfree.x86_64

- x11-driver-video-nvidia-current-430.64-8.mga7.nonfree.x86_64

And rebooting...
Comment 10 Morgan Leijström 2020-04-30 08:22:21 CEST
Now before reboot another issue: switching desktops it may switch but not update: i initially show image of one dektop, moving the mouse it updates parts of a program that is on the actual desktop. Kinda spooky.  Unusable.
Comment 11 Morgan Leijström 2020-04-30 11:26:20 CEST
I still get now and then:
apr 30 09:56:36 svarten.tribun kernel: nouveau 0000:01:00.0: DRM: core notifier timeout

And it still seem to be loading nvidia proprieatary i assume?

So how to really clean out all nvidia proprietary parts from the system more than removing nvidia packages?

/!\ Note this is a production machine and i need to get back to using nvidia-current with opencl and cuda !
Comment 12 Brian Rockwell 2020-04-30 16:33:41 CEST
sounds like I need to try kernel-desktop-latest and see if that behaves differently than kernel-server.

May try swapping drives later today.

Thanks everyone, seems nouveau is wonky regardless.
Comment 13 marc laan 2020-04-30 18:23:51 CEST
After upgrading my kernel on the 64 bit AMD pc from 5.5.15 to 5.6.6-1, the video began acting strange (see attached screenshot). 
On the screen names of files and titles of menus showed missing characters at random. Using the menus is almost impossible.

It seems mainly a desktop screen affair, as the Konsole is readable o.k.

I went back to kernel version 5.5.15, and the problem is not there.

My system is:

Advanced Micro Devices, Inc. [AMD]|K8 [Athlon64/Opteron] HyperTransport Technology Configuration.

Driver is nouveau, not nvidia (although my graphics card is nvidia, but not supported by MGA 7.1).

Comment 15 Morgan Leijström 2020-04-30 20:16:12 CEST
Great!
I will try them tomorrow.

For a clean test and make sure no stuff or settings for nvidia proprietary drivers are left, do we need to do more than select to not use proprieatrye driver, and then remove nvidia packages, or can we do more?
Like removing files, settings, edit kernel boot arguments?
Comment 16 Morgan Leijström 2020-05-01 12:02:43 CEST
From Thomas on qa-discuss:
To clean out any nVidia stuff:

1. use mcc to switch to nouveau
2. switch to text console (Control-Alt-Fx and log in as root)
3. remove any nvidia rpms
4. run "dracut -f" to remove nvidia modules and references from initrd
5. reboot

(The reason for step 2 is that the DE can/will lock up when you remove the drivers) 


And before that I updated to all in comment 14
Rebooted, and journal is much cleaner now than before:

I will continue to use the system like this occasionally over the weekend, and report back.
Comment 17 Morgan Leijström 2020-05-01 21:17:54 CEST
Less problems, but still desktop hung on me:

I have used it an hour accumulated, including thunderbird, libreoffice, video in firefox, test OK msw7 in virtualbox with firefox with video.
No visual artifact of any kind, no percieved delays.  All time BOINC have been chewing on all day.

But then i changed desktop, which visually works nicely, and have severalt imes durign the day, but this time it became unresponsive except for mouse pointer.  No keyboard chord works. Log say power button is detected but no shutting down action starts from that either.

I see it have logged:

...And later i held button for 4s to power it off.

Now i have to switch back to nvidia proprietary.

Updating to x11-driver-video-nouveau-1.0.16-3.mga7 didn't solve my problem of getting artifacts on the desktop screen.

Is there a way I can contribute by searching in the logs?

My system is:

Advanced Micro Devices, Inc. [AMD]|K8 [Athlon64/Opteron] HyperTransport Technology Configuration.

Driver is nouveau, not nvidia (although my graphics card is nvidia, but not supported by MGA 7.1).

Card:NVIDIA GeForce 6100 to GeForce 7950: NVIDIA Corporation|NV44 [GeForce 6200 TurboCache] [DISPLAY_VGA]

nouveau_screen_desktop_artefacts_missing_characters_and_menus

As mentioned in an earlier post, here's a screenshot of my desktop screen: many artefacts and missing menu lines after upgrading. Last three recent updates of MGA7 didn't correct this problem.

Comment 21 Marja Van Waes 2021-09-07 14:11:26 CEST
Hi bug reporter and hi assignee and others involved,

Please reopen this bug report if it is still valid for Mageia 8 or 9(cauldron), and change "Version:" in the upper left of this report accordingly.

This report is being closed as OLD because it was filed against Mageia 7, for which  support ended on June 30th 2021.

Thanks,
Marja

Resolution: (none) => OLD
Status: NEW => RESOLVED
