As part of testing the new system, I adjust displays to my configuration; which required changing right-display to portrait-left tilt. On performing that function I get ** Expected results I expected the right-display to portrait-left tilt, and left-display to remain unchanged. ** Actual results Right display did portrait-left tilt & is perfectly usable (what I'm using now). The left display however is now just a blocky mess that changes as I type, and slowly flashes (at the bottom of display). https://photos.app.goo.gl/BvUTkDczbqU78q8G6 ** Package Package is likely wrongly marked; likely radeon related (or whatever graphics exists in this box) ProblemType: Bug DistroRelease: Ubuntu 21.10 Package: linux-image-5.11.0-20-generic 5.11.0-20.21+21.10.1 ProcVersionSignature: Ubuntu 5.11.0-20.21+21.10.1-generic 5.11.21 Uname: Linux 5.11.0-20-generic x86_64 ApportVersion: 2.20.11-0ubuntu67 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: guiverc 780 F.... pulseaudio /dev/snd/pcmC0D0p: guiverc 780 F...m pulseaudio CasperMD5CheckResult: pass CurrentDesktop: KDE Date: Mon Jun 28 14:47:15 2021 InstallationDate: Installed on 2021-06-28 (0 days ago) InstallationMedia: Kubuntu 21.10 "Impish Indri" - Alpha amd64 (20210627) IwConfig: lo no wireless extensions. enp0s25 no wireless extensions.
