Bug ID: 107731
Summary: radeon (amdgpu) DisplayPort loss of max-resolution on
DP monitor (after monitor power saving / idle)
Product: DRI
Version: XOrg git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: freedesktop-bugs@fermulator.fastmail.org

dmesg output post DP disconnect + reconnect to fix resolution
as an extension of the story from:
* https://bugs.freedesktop.org/show_bug.cgi?id=107560#c9
after a few kernel/driver upgrades and weeks later, that is no longer
reproducible - and is instead replaced by lesser issues still plaguing the
monitor connected via display port
$ uname -r
4.17.17-100.fc27.x86_64
noticed that the same monitor (connected via DisplayPort) had mis-match
capabilities (wasn't able to go max resolution)
```
$ xrandr
Screen 0: minimum 320 x 200, current 3840 x 1200, maximum 16384 x 16384
DisplayPort-0 connected primary 1920x1080+0+0 (normal left inverted right x
axis y axis) 0mm x 0mm
1920x1080 59.95*
1600x1200 59.95
1680x1050 59.95
1280x1024 59.95
1440x900 59.95
1280x800 59.95
1280x720 59.95
1024x768 59.95
800x600 59.95
640x480 59.95
HDMI-A-0 disconnected (normal left inverted right x axis y axis)
DVI-D-0 connected 1920x1200+1920+0 (normal left inverted right x axis y axis)
518mm x 324mm
1920x1200 59.95*+
1920x1080 59.95
1600x1200 60.00
1680x1050 59.95
1280x1024 60.02
1440x900 59.95
1280x960 60.00
1280x800 59.95
1280x720 59.95
1024x768 60.00
800x600 60.32 56.25
640x480 59.94
```
The " 1920x1200 59.95*+" option is missing from the display port monitor.
If I disconnect the DP, and reconnect, it comes back.
```
$ xrandr | grep +
DisplayPort-0 connected primary 1920x1200+0+0 (normal left inverted right x
axis y axis) 518mm x 324mm
1920x1200 59.95*+
