Intel hd graphics 770 (12th generation) freezes

deathangle908 · 2021-12-27 16:31:34

Intel 770 is seems to be really unstable at this moment. I had this issue when I tried to use it. I got

i9-12900k
Asus z690-p with 2 graphic outputs: HDMI, DP
Radeon MSI 6900 rx with 4 graphic outputs
6 monitors, 2 of them are plugged to motherboard and 6 to MSI 6900 rx

I'm using xf86-video-intel with all system up to date. I also added thing options to i915.

: cat /etc/modprobe.d/i918.conf 
options i915 force_probe=4680

If I have this xorg.conf

Section "Device"
  Identifier  "Card0"
  Driver      "intel"
  BusID       "PCI:0:2:0"
EndSection

Section "Device"
        Identifier  "Card2"
        Driver      "amdgpu"
        BusID       "PCI:3:0:0"
EndSection

Symptoms

If I unplug all monitors from motherboard, everything works fine. I
If I plug monitor to DP of motherboard, xorg starts, mouse seems to work on both integrated and discrete videocards. I can start a few apps. Xrandr doesn't even show monitors from discrete videocard only from intel. KDE menu doesn't appear. Everything is unsuable.
If I plug monitor to hdmi motherboard, it's even worse. Xorg won't start, kernel freezes, no output in dmesg after X starts from previus boot is present. I can NOT switch to 2nd or other terminals. Discrete graphics doesn't work either. System is completely dead.
If I unplug msi discrete videocard from motherboard, symptoms are the same. with HDMI it hangs, with DP it's somhows runs but nothing seems to work fine.

I ran exactly the same configuration with 6 monitors and i7-8700k and everything worked fine. I mean same ssd (if I unplug ssd from this motherboard and put it to old one - everything works. So I'm pretty sure I configured everything correctly, despite if new generation requires some flags)
Logs with 4 monitors to discrete cart, and 1 monitor to motherboard DP, motherboard hdmi has nothing connected to it.

  Driver      "intel"

Try putting modesetting as driver instead of intel .

I tried, if I have a monitor plugged to DP - it works exactly the same as intel driver, xrandr shows only motherboard monitor. I can start some programs, KDE is unusable.
If I unplug all monitors from motherboard leaving 4 monitors connected to discrete card, with intel driver it works fine, with modesetting it xorg doesn't start at all.

If we ignore HDMI for the moment and focus on the setup w/ DP on the Mobo and the other outputs on the AMD gpu: what's the output of "xrandr --listproviders" and can you https://wiki.archlinux.org/title/PRIME#Reverse_PRIME it w/ "xrandr --setprovideroutputsource AMD_PROVIDER_HERE INTEL_PROVIDER_HERE" ?

However, before even that:

mouse seems to work on both integrated and discrete videocards … Xrandr doesn't even show monitors from discrete videocard only from intel. KDE menu doesn't appear.

What is the "xrandr -q" output and because of the mouse and KDE menu situation: what if you suspend the compositor (SHIFT+Alt+F12)?

Correct me if I'm wrong, as far as I understand prime. Is a topology where you have a cabel output that's connected to 1 card and 2nd card can output video thought 1st card. E.g. A laptop has integrated card intel HD and discrete Nvidia. It has built in display, and this display is connected to the port that's wired via bus that goes from CPU (to be concrete from its GPU) directly. When using hybrid card, OS decides when to switch to discrete GPU and it renders data and outputs it via this bus to the same port internal port. Being that said, when you have desktop motherboard with discrete GPU which can't outout video to motherboard port, neither intel hd 770 can't wire it to videocard GPU PRIME wouldn't work.

P.S. I have no idea why this article says

PRIME is a technology used to manage hybrid graphics found on recent desktops...

It's not limited to a particular form factor.

W/o that and 2 GPUs you'll either have to use xinerama (what defies xrandr which a lot of stuff blindly expects to be present, so that's no fun) or 2 separate screens (where you can use the same input devices but not move windows from one screen to another, ie. you'd eg. run two different desktop sessions, one on :0.0 and one on :0.1)

Please post the requested output of

xrandr --listproviders

If I plug this videocard and this sso to another motherboard with intel i8-8700k and boot it from this ssd and this os, it works out of the box. Why do I need extra tools? As I see it's not related to configuration but rather to drivers support. Anyway If I use intel 770 on i9-12900k and remove discrete videocard and boot only with DP connected to motherboard, integrated graphics doesn't work correctly. It boots, but it's unusable.

Will you please post the requested output?
Because if there is prime support but the different IGPs provide different labels and you're a redirection script in place for the one but not the other, there's your answer.

It's not working by fucking magic nor can I tell you remotely what your system looks by that approach.
