[SOLVED] Screen problem on Acer Aspire A515-62

So, yesterday I updated my system using command

sudo pacman -Syyu

Now when I boot my laptop, everyting is fine, acer logo is fine, grup menu is fine, but when SDDM starts up this happens: (Image of the problem). Everything is messed up. The colors are totaly bad everything looks awful and unreadable, it looks like my GPU is overheating. However it is not a hardware problem because as I mentioned everythink works fine at boot. Temporary fix is to hard shutdown my computer, meaning that I have to unplug charger and battery. If I try to shut it down normal way or reboot, the problem will appear again. Bellow are some informations regarding my hardware and software configuration.

Hardware:
    Operating System: Arch Linux
    KDE Plasma Version: 5.20.0
    KDE Frameworks Version: 5.75.0
    Qt Version: 5.15.1
    Kernel Version: 5.9.1-arch1-1
    OS Type: 64-bit
    Processors: 8 × Intel® Core™ i5-8265U CPU @ 1.60GHz
    Memory: 7.6 GiB of RAM
    Graphics Processor: Mesa Intel® UHD Graphics 620 (Whiskey Lake) - kernel module: i915
    3D Accelerator: NVIDIA GM 108M [GeForce MX130] (rev. a2) - kernel module: nvidia

Software:
    Xorg log
    I have no xorg conf in /etc/X11
    NVIDIA drivers: proprietary
           version: 455.28-7
           architecture: x86_64

Edit: replaced old Xorg log with correct one.

Re: [SOLVED] Screen problem on Acer Aspire A515-62

Have the same issue on Xps 9550 with nvidia gtx 960.

Weirdly enough running

i3lock; xset dpsm force off

solves the issue untill the next reboot...

Might it be related to the https://www.phoronix.com/scan.php?page= … .9-Delayed ?

Apparently i cannot access the nvidia gpu (nvidia-settings -> error, optirun [ sth] -> error (cannot access seecondary gpu , no device detected).

I waw suspecting it could be this, so I downgraded my kernel to 5.8.14. It works for now, but I performed just one restart so far, so I cannot confirm it.

Re: [SOLVED] Screen problem on Acer Aspire A515-62

the xorg log is old, however symptoms read like race conditions for the graphics device, set up early KMS for i915 https://wiki.archlinux.org/index.php/Ke … _KMS_start

Looks alrightish, did you try my suggestion? I'd personally also recommend you remove xf86-video-intel and any config referencing it, it hasn't really seen much active maintenance in a few years by now and often uses a lot of older ways to initialize the HW.

So, right now it really looks like the problem with nvidia drivers and kernel. After the first restart after the downgrade, I restarted my laptop again and everything worked. Now I want to test V1del solution, so I upgraded the kernel to 5.9. After restart (before applying the changes) I restarted it again and the problems re-appear. Now I will try to apply V1del solution and let you know.

I tryied it and it worked. Thank you. I will mark this thread as solved. Howewer, I would like to point out that this problem may be related to the problem of nvidia drivers  which Griffin001 metioned.

Re: [SOLVED] Screen problem on Acer Aspire A515-62

It shouldn't be, you aren't using CUDA nor OpenCL in normal Optimus workloads and FWIW it does look like you aren't actively using them. And if you did add i915 that's an issue with the intel drivers (... intel is what drives your display so it needs to be ready before all) If it's ultimately a race condition issue it's quite possible that what you changed now is the expected and intended fix.
