It looks like suspend-resume works with glamor if I have the next two lines (I think, still unsure, that both are necessary):

First observed on latest Mint (20.2)... then discovered Peppermint 10 was not affected. I believe Peppermint 10 is based on 18.04 and I am unsure why it is not affected. I tested with many versions of Ubuntu... Before 17.04... no problem... but was using EXA acceleration. 17.04 first to use Glamor... screen corruption is not obvious... but dmesg show GPU lockup... 17.10 and following is really problematic after resume, but possible to Ctrl-Alt-F4 to go to a text console and ... sudo reboot. There is a possibility I missed the exact version as I don't have my notes near me. Adding Option "AccelMethod" "EXA" at the good place in xorg.conf file have fixed the issue. I am unlikely to have access again to that specific computer in the future. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu69 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu 6610 F.... pulseaudio CasperMD5CheckResult: pass CasperVersion: 1.465 DistroRelease: Ubuntu 21.10 IwConfig: lo no wireless extensions. enp63s0 no wireless extensions.
