Comment 10 for bug 1978980

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:
