Title:
Graphic driver (radeon) screen problem in kernels released after
2019-06-09
Status in linux package in Ubuntu:
Incomplete
Bug description:
I've got a problem with some kernel modules (probably radeon) which cause
screen problems. It occurs only on internal laptop screen.
I found that problem is present in all kernels released after 2019-06-09
18:25. Last kernel which works corectly is v4.19.49 2019-06-09 10:04. v5.2-rc4
2019-06-09 18:25 has this bug and also v4.19.50 2019-06-11 13:06. So I think
there are some changes in all kernel packages between hour 10:04 and 18:25 that
day (2019-06-09) casue future problems.
This may be problem with radeon modules cause screen goes strange when
console shows "fb: switching to radeondrmfb from VESA VGA" (I remove
"quiet splash" from GRUB menu).
In this video I show described problem ->
