dmesg output with error logging
Hello,
after I updated archlinux with 'pacman -Syu' I cannot switch on both graphics cards (amd+intel) concurrently anymore via vgaswitcheroo. I need the parallel activation because Intel feeds the notebook screen and amd feeds my external screen.
Default graphics card is the Intel one. This configuration is working well (only notebook screen). I have another grub boot option that switches on the dedicated graphics card before the display manager is started:
echo ON > /sys/kernel/debug/vgaswitcheroo/switch
echo DIS > /sys/kernel/debug/vgaswitcheroo/switch
When I add a further 'echo OFF > ...' command, the Intel graphics card will not be active and the error will not happen. But in this case I do not have an output on my notebook screen.
I had a look at the dmesg output and it told me to create a bug ticket ;-)
Error: [drm] GPU HANG: ecode 0:0x85ffaafc, in Xorg.bin [1080], reason: Ring hung, action: reset
Notebook: HP Envy 14-1101eg
Best regards
Fabian
