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:

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.
