[amdgpu] Wrong external screen resolution after wake up from sleep

[Miroslav Šimko]

After the Ubuntu distro upgrade (upgrade from LTS 20.04 to LTS 22.04, running KDE) I started experiencing a problem with external screen resolution after the wake up from sleep. The monitor resolution is small (1280x768) and doesn't respect the setting prior the sleep (1920x1200).

After the wake up from sleep:

```
> xrandr
HDMI-A-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 connected primary 1280x768+0+0 (normal left inverted right x axis y axis) 535mm x 339mm
   1280x768 59.94*
   # a list of lower resolutions
```

There is an error when trying to change the setting to the highest resolution supported by the monitor (which is not included in the above list).

```
> xrandr --output DisplayPort-1 --mode 1920x1200
xrandr: cannot find mode 1920x1200
```

After the turn off and turn on of the external monitor, the resolution is somehow added to the xrandr list:

```
> xrandr
HDMI-A-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 connected primary 1280x768+0+0 (normal left inverted right x axis y axis) 535mm x 339mm
   1920x1200 59.95 +
   # a list of resolutions
   1280x768 59.94*
   # a list of lower resolutions
```

Now it is possible to change the resolution:

```
> xrandr --output DisplayPort-1 --mode 1920x1200
# no output, the resolution was successfully changed
```

After the change, the resolution is successfully changed and xrandr gives proper output:

```
> xrandr
HDMI-A-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 535mm x 339mm
   1920x1200 59.95*+
   # a list of lower resolutions
```

The problem is not present on fresh start. However, it is consistently present after the wake up from sleep.

What can cause the problem and how may I fix it?

Running AMD based laptop (Ryzen 7 3700U with integrated graphics), the external monitor is connected via USB-C. There are no problems with laptop screen resolution, only external monitor is affected.

Same problem with GNOME on 22.04, see comments here: https://askubuntu.com/questions/1408789/wrong-external-screen-resolution-after-wake-up-from-sleep

The bug is also effective on ubuntu 20.04.3 - fresh installation with all updates. But it wasn't effective prior updating.
After downgrading xserver-xorg-legacy and xserver-xorg-core from 2:1.20.13-1ubuntu1~20.04.3 back to the version 2:1.20.13-1ubuntu1~20.04.2, the problem seems to be gone. I'll come back in a week and confirm whether this is really true.

[Miroslav Šimko (msimko81)]

No success, the downgrade doesn't work either. Today morning, wrong resolution after the wake up. It seems as if the monitor wakes up with correct resolution if there is just a little period between sleep and wake up. But when there's a longer period in between, it wakes up with wrong resolution.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Mike (michalzukowski)]

Not only the resolution is wrong for the USB-C display but also the order is different. Unplugging and plugging the connector seems to fix the issue (Ubuntu 22 LTS).

[Jake Jellinek (jake-jellinek)]

I don't know if my problem is the same as this bug or not. Ubuntu 22.04.1 LTS clean install.

Dell Latitude 5520 laptop.

I have two external monitors attached, one via HDMI and one via USB-C (different resolutions on each monitor)

After the screen locks, when coming back after 15 minutes or so and putting in my password to resume my session, the USB-C monitor has changed to a lower resolution and the layout of the three monitors has changed around.

I correct this by unplugging the usb-c connector and plugging it back in again whereupon everything goes back to how it should be.

I have the same issue on a Dell Latitude 5490 running Ubuntu 22.04.1 LTS.
The Dell is connected via USB-C to DisplayPort (DisplayPort alt mode) to an external monitor (Dell Alienware aw3821dw).
After the screen locks and display went to sleep mode and I return to my desk, the screen always has a resolution of 1024x768 and I can see the following in my syslog:

Fresh installation Ubuntu 20.04 LTS with all updates / Fresh installation with all updates 22.04 LTS.

Thinkpad X230 and external display. Default resolution external display 2560x1440. After screenlock the external display has a different resolution. Sometimes 1920x1080 or 1280x720. Only unplugging and plugging it back solves the problem.

Experiencing this as well.

Experiencing this on Dell XPS 13:

[Drew Andersen (drewser42)]

Disabling DDC/CI on my monitor appears to have resolved this issue for me.

[FrozrLighting (frozrlighting)]

I have the same problem on my Dell Latitude 5400 on Ubuntu 22.04.2 LTS connected via HDMI to AOC Q3279VWFD8. After sleep the resolution goes from 2560x1440 75hz to 1920x1080 60hz

[Francisco R. Santos (frsantos)]

I see that if I disable "Automatic screen lock", it does not happen any more, even if the screen goes blank for a long time.

[Arthur (the-great)]

Happens with me too after sleep/wakeup lenovo x1 carbon gen8 / HDMI LG 27GL850 which should run at 2460x1440@60hz but instead its 1920x1080@60hz.
I should either restart the system to make the proper resolution work again or reconnect hdmi cable like 10-20 times

[nairboon (nairboon)]

I had the same issue with a NEC display on Debian stable and AMD gpu. Interestingly, *enabling* DDC/CI seems to solve it, at least so far.

[Wojciech Semik (wojtek-semik)]

I have the same issue. Kubuntu 22.04, after sleep/screen lock my usb-c -> display port connected monitor goes from 5120x1440 down to 3840x2160.
