A little investigation and the following implements johnnyl33-k's workaround from the command line. $ xrandr --output eDP --reflect xy --rotate inverted --mode 1366x768 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1885474 Title: 1366x768 screen resolution broken, all other resolutions OK To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1885474/+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

I have the same issue. As mentioned in reddit thread in OP, the login screen displays properly at 1366x768. I'm running MATE so I'm not sure how to implement the workaround @johnnyl33-k mentions for Xubuntu since there are no reflection options. I will note setting rotation to 'upside-down' in Control Center->Monitor Preference does not suffer from the tearing the 'normal' rotation does. It's just hard to work upside down! -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1885474 Title: 1366x768 screen resolution broken, all other resolutions OK To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1885474/+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

It happened to me as well on my lenovo ideapad laptop with Xubuntu 20.04, and I came with a weird but functional workaround: I opened the display window, selected the 1366x768 resolution, rotation: inverted and reflection: horizontal and vertical, then applied.
