Oh, also your kernel is stuck in recovery mode: [ 136.650] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.15.0-39-generic root=UUID=8a9d54df-bf77-4277 -990d-781804a2250b ro recovery nomodeset
which will cause graphics problems. To fix that, reboot and then hit Esc as soon as the purple screen appears. Now navigate the menus and choose a regular kernel that does not have the recovery option. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1803504 Title: Screen stops redrawing sometimes when moving windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1803504/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
