Did some more testing: * If I logout when the screen flickers, it also flickers in the login screen after logging out and also after logging back in.
* After a reboot (without logging in), the flickering disappears. After suspending from there and waking up, the flickering appears on the login screen. * After another reboot (this time logging in), there is also no flickering. * Booting from a live Fedora 32 USB, the flickering after suspend does *not* occur, even after multiple suspends. * Booting from a live Ubuntu 20.04 USB, the flickering *does* occur after suspend. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1885363 Title: Screen flickers after waking up from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1885363/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
