This looks like a signalling problem. There doesn't seem to be any corruption in the image. Only the signal to the monitor doesn't correctly match the frequencies that the monitor requires.
As a workaround please try selecting 'Ubuntu on Wayland' from the login screen. Please also try a different VGA cable if you can. ** Summary changed: - Screen corruption with multi monitor setup + VGA image is ghosted and stretched (LG L1953S) ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- 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/1890436 Title: VGA image is ghosted and stretched (LG L1953S) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890436/+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
