Description of problem: After the computer comes back from resume, rarely it produces strange screen distorsions, as on attached picture. Version-Release number of selected component (if applicable): How reproducible: 1. sleep the machine 2. wake up 3. sometimes it comes back with a picture like on the attached one.

Created attachment 6306 [details] Screen distortion This is an example of the problem
and for graphic drivers are you using ?
The hw is a thinkpad r61, with nvidia card. I am using the propriatory drivers.
I confirm this - looking exactly the same after suspend/resume, two laptops. - but here it seem to be every time after suspend/resume :( The black and white areas are sometimes but sometimes not sparsely dithered with pixels of various colours. I recognise the symptom from before and i think there is an old bug about it but i could not find it. Mine are thinkpad R61 and T61p both with nvidia proprietary drivers, OK with noveau. Graphics: Nvidia G86M ( Quadro NVS 140M ) driver: nvidia340 (340.76-1.mga5.nonfree) ( in graphic driver list named "GeForce 8100 to GeForce 415" ) Problem shows with kernel-desktop-3.19.8-2 Now i tried reinstalling elder kernel and they work. WORKAROUND (?) Now the strange part: the newest 3.19.8-2 also works after remove and reinstall of it ?! So i tried on the other laptop to just # dracut -f , and reboot, and since that it have worked several suspend/resume. (Maybe i am just lucky, i will report back if things change) Could you try that Tamás ?
CC: (none) => friSource RPM: (none) => kernel-desktop-3.19.8-2.mga5-1-1.mga5.x86_64.rpm
(slight correction: the *Thinkpad T61p* graphic chip is Nvidia G84GLM [Quadro FX 570M], using same driver)
Created attachment 6676 [details] MCC hardware identifier say it find no nvidia module Strange: I run the Mageia Control Center from terminal and whne i go into "Browse and Configure Hardware" and click the video card i get in terminal: modinfo: ERROR: Module Card:NVIDIA GeForce 8100 to GeForce 415 not found. see attached screenshot But i get the Nvidia splash screen at X login, and apparently it works... Is this normal or something i should report against drakxtools or what? Or may there be some configuration issue that may lead to the bug here?
On my computer this bug was never always reproducible. So I can put it in sleep a couple of times (just did pm-suspend for 5 times, everything works, so it might nor just a few). Also I haven't seen the bug in a week or so. I have done dracut -f anyway. And I will reboot it and check how many suspends I need to do. Also (but might be it is an other bug), I have a feeling that this is may be related to KDE somehow (not sure how:) ) cause since a week (maybe 2 weeks) I have a really annoying problem, that after (usually the first resume), HW keys are no longer working to put the machine to suspend (though pm-suspend works). Also it takes up to a minute to KDE to put the reboot/shutdown window, while the whole kde panel is frozen...
I see this bug again on kernel 3.19.8-2. Now changing to 3.19.8-1, report back later. Regarding it not suspending i have seen it too on the R61 but not the T61p. Sometimes i notice it have not suspend automatically by timeout, and then also the Fn+moon key often do not work. But i believe it is a separate issue.
With 3.19.8-1 I still do not see this bug, but found another: black screen at resume because of bluedevil, filed bug 16072 (strange it did not happen before, but a couple times today) In a few days I will try to downgrade the nvidia driver instead.
Summary: After resume screen distortions => Nvidia: After resume desktop have white&black square stripes
BTW we run almost always KDE on all our thinkpads, but i saw the problem also on one or more of {gnome,cinnamon,mate} which i tried on the R61.
New variant: running kernel 19.8.1 i have so far never seen desktop background distorted, but now after suspending with Mageia Control Center and its log window open, the log window after resume contain the distortion (and no text). No other symptom. Because of bug 16072 i now swith to latest kernel again and try locally compiled nvidia driver per instructions in bug 15328.
Whiteboard: (none) => MGA5TOO
Most of the resume problems are now gone and it's stable, but one: After resume, the KDE power plasmoid (screen brightness, battery, etc..) "freezes" to the desktop, while in the systray it loses it's icon (acts like a place holder). It cannot be moved, but can be disabled and enabled again, after that it behaves normally. Also it's possible to set the brightness, enable/disable powermanagement,etc...
Have not seen original problem for long. I guess we can close as old.
The laptop I had the issue on is no longer working, on the new thinkpad yoga, I have no such issue.
Status: NEW => RESOLVEDResolution: (none) => FIXED
Yep i have a heap of families total four defunct T6x and R6x with the infamous GPU death. The fifth with Nvidia GPU still working (5 years old) have no issues. Except for the GPU death these are marvellous machines and pretty cheap to buy used just because people think they are "old" :)
