In my instance (Xubuntu 18.10 with nvidia 415 from the graphics drivers PPA) I was able to fix the lock screen resolution by using the following:
Section "Files" ModulePath "/usr/lib/x86_64-linux-gnu/xorg" ModulePath "/usr/lib/xorg/modules" EndSection My system has /usr/lib/nvidia, but no xorg directory located there. Likewise, no nvidia/xorg directory path under /usr/lib/x86_64-linux-gnu. There was only xorg as listed above with my corresponding nvidia modules. This workaround does not fix the TTY screen resolution or the Xubuntu boot/loading spash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760068 Title: Wrong resolution at unlock screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/light-locker/+bug/1760068/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
