I have a Dell Optiplex 7010 half a dozen years old or so. I put a new Sceptre C248B-144RN monitor on it that uses DP input. I’m running Budgie 20.04.
The 1920 x 1080 resolution for the monitor is not always properly recognized when the machine is woken up from being idle and it reverts to 768 x 480 instead of 1920 x 1080. The quickstart/troubleshooting pamphlet included with the monitor describes this as a driver problem. The only suggested fix is to reboot. Rebooting works and so does logging off and back usually work. This, of course, is a nuisance.
Dell has Ubuntu drivers but the newest is from 2015 for Ubuntu 11.10. I’d consider trying this driver but first I’d like to see if anyone as advice about whether it will cause problems. I can see where it might go either way.
Thanks for thinking about it.
