[solved] GPU Intel driver problem

I have a Thinkpad X1 Extreme gen 3

Hardware:
- Intel(R) Core(TM) i7-10750H
- Intel Corporation CometLake-H GT2 [UHD Graphics] (rev 05)
- NVIDIA Corporation TU117M [GeForce GTX 1650 Ti Mobile] (rev a1)

(external video outputs are attached to nvidia card)

To make it simple for now, I've blacklisted nvidia and nouveau.

% xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x44 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 2 associated providers: 0 name:Intel

Now, if I change a terminal (ctrl+alt+Fx) I'll get a screen full of artifacts - actually I have no clue how to call it. Please take a look at this photo of how it looks like (hosted on Tresorit, if there is a better way, please let me know, I'll re-upload.)

This is not a crash, there's nothing new on Xorg logs, everything works under the hood, this is just a video problem.

Workarounds:
- put machine to sleep by closing the lid, then wake up
- reconfigure laptop to render on Nvidia card (this generates a list of other problems)
- if nvidia card is active (just for external video outputs), I could have a different terminal with a different screen layout, then switching to it triggers kind of a refresh  and fixes the problem.

Even if you don't know the answer, I would also appreciate any ideas how to call this effect, right now I have no clue what to ask Google.

Some more context:
I have this laptop for 15 months. I was forced to buy a model with Optimus/Nvidia, because nothing else was available. I'm a happy Linux user for like 20 year now, and the amount of video problems I have with this machine is insane - here I'm just starting with one. I was working around them, assuming this will be fixed in time, but it's actually getting worse. At this point I'm considering selling this laptop and going back to plain Intel machine.

Re: [solved] GPU Intel driver problem

Do you use xf86-video-intel ot modesetting xorg driver?
If not already, try the latter.

Re: [solved] GPU Intel driver problem

name:Intel

try the latter

grep -ri intel /{etc,usr/share}/X11/xorg.conf*

to make sure there're no residual references to the driver, otherwise X11 might fail to start.

Re: [solved] GPU Intel driver problem

Thank you, changing to the modesetting w driver solved the problem.
I gave it couple of days, because I still see those artifacts, they still flash for a split second, and couple of times even showed up permanently, but switching consoles back and forth fixes it quick.

Are Intel drivers just in a bad state this days, or most likely is it related to complicated Optimus wiring?

Re: [solved] GPU Intel driver problem

xf86-video-intel has not been actively maintained for 10 years it should not be used unless you have a system from that timeframe, the focus is on the modesetting driver/wayland.
