Bug ID: 107858
Summary: Screen resolution wrong after turning monitor off and
on
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel at lists.freedesktop.org
Reporter: lopa at mailbox.org
This is related to bug 105046, which was closed as RESOLVED FIXED.
Unfortunately, the issue still exists. This is my configuration:
OS: OpenSuse Tumbleweed with kernel 4.18.0
Installed amdgpu packages:
libdrm_amdgpu1-32bit-2.4.93-1.1.x86_64
libdrm_amdgpu1-2.4.93-1.1.x86_64
xf86-video-amdgpu-18.0.1-2.1.x86_64
Prozessor: AMD Ryzen 5 2400G with Vega Graphics
Monitor: Dell U3011 (resolution 2560x1600) connected via DisplayPort
After switching the monitor off and on, the screen resolution is sometimes
changed to a very low value. Most of the time there's no problem, but sometimes
the resolution is changed to 800x600. A reboot is required to set it back to
2560x1600.
It seems, that there are several different error cases. In the past, I've seeen
messages in the dmesg output and in the syslog, but just now neither dmesg nor
the syslog did show any errors, there are only the following lines added to
/var/log/Xorg.0.log:

The EDID information is correct, but for some reason the amdgpu driver asumes,
that the highest possible resolution is 800x600.
