Hi,

I recently bought an Intel NUC with an J5005 CPU and an UHD 605 graphics. and I have strange artifacts at the top of the screen.

@3 seconds: https://drive.google.com/open?id=1_1KrXVlI-KY_KTqanpj1IUokogGCYOxP

this comes every few seconds.

gbm or i965 or -modesetting?
Comment 3 Lionel Landwerlin 2019-03-11 01:47:51 UTC
Could you attach the output of glxinfo?
Thanks!

Actually found the following :

https://bugzilla.redhat.com/show_bug.cgi?id=1645553

https://gitlab.freedesktop.org/xorg/xserver/merge_requests/131

Seems to be modesetting issue.

Also i disabled the compositor as mentioned here: 

https://bugzilla.redhat.com/show_bug.cgi?id=1645553#c8

and the messages are gone, however I still have those artifacts.

Looks a lot like https://bugs.freedesktop.org/show_bug.cgi?id=108085
I'm inclined to punt it back to i915.

Can you boot your kernel with the following option : i915.enable_fbc=0 
If this goes away then I'll close with duplicate.
Comment 9 Denis 2019-03-11 15:55:23 UTC
there was also one more suggestion to switch from "modesetting" to "intel" driver.


https://bugzilla.redhat.com/show_bug.cgi?id=1645553#c11

for checking driver in use you can do this:

egrep -i " connected|card detect|primary dev|Setting driver" /var/log/Xorg.0.log
