my laptop: HP Compaq nx9420
my grafic card:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV530/M56-P [Mobility Radeon X1600] (prog-if 00 [VGA controller])
attachment:
the bug-apport-file
Description:
I start ubuntu 18.04 LTS (Kernel 4.15.0.33) in textmode;
-> as soon as the kernel-module radeon.ko is loaded the screen starts flickering
when starting the grafic-mode the flickering continues; so the screen is unusable.
when setting the option "radeon.modeset=0" (thus: not use radeon drivers) the screen does not flicker
but the resolution is limited to 1400x1050 (instead of natural 1680x1050)
so I can not use this as work-around
when using the old ubuntu 14.04.05 LTS (Kernel 3.13.0-157)
the screen is o.k. NO flickering in textmode, nice grafic, NO flickering
xrandr tells: 1680x1050 60.1
so I must stay on old ubuntu 14.04.05 ??? |
=== SRU Justification ===
[Impact]
Screen flickers when using radeon.ko.
It's a regression, it didn't happen on Trusty.
[Fix]
Quote the original commit log:
"Instead of the closest reference divider prefer the lowest".
[Test]
Affected user confirms it fixes the issue.
[Regression Potential]
Low. Only affect radeaon, and it's in upstream stable tree.
