** Description changed: + [ Impact ] + When the nvidia driver is installed, the screen turns off when trying to set some fractional scaling values like 150%. And it stays off even after rebooting and logging in again. And from ssh I can see there's no current mode set anymore (just like in bug 1869750): $ xrandr Screen 0: minimum 8 x 8, current 960 x 600, maximum 16384 x 16384 DVI-I-0 disconnected (normal left inverted right x axis y axis) DVI-I-1 disconnected (normal left inverted right x axis y axis) DP-0 disconnected (normal left inverted right x axis y axis) DP-1 connected primary (normal left inverted right x axis y axis) 1920x1200 59.95 + 59.88 - ProblemType: Bug - DistroRelease: Ubuntu 20.04 + [ Test case ] + + In a Nvidia system: + - From g-c-c enable fractional scaling + - Set all the available fractional scaling values and ensure they work + + In any case the screen should be turned off + + [ Regression potential ] + + Wrong screen size is set and panning might be enabled. + + --- + + ProblemType: BugDistroRelease: Ubuntu 20.04 Package: mutter 3.36.1-3ubuntu2 ProcVersionSignature: Ubuntu 5.4.0-24.28-generic 5.4.30 Uname: Linux 5.4.0-24-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 CasperMD5CheckResult: skip Date: Fri Apr 17 15:51:15 2020 InstallationDate: Installed on 2020-02-03 (73 days ago) - InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Alpha amd64 (20200124) - SourcePackage: mutter + InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Alpha amd64 (20200124)SourcePackage: mutter UpgradeStatus: No upgrade log present (probably fresh install)
