2019-06-27 04:03:02 Kai-Heng Feng description 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. === Original Bug Report === my laptop: HP Compaq nx9420 my grafic card: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
