I prefer to use Fedora when possible but in F26 and F28, I've been unable to get Gnome Shell to agree with my screen rotation options. I keep both my monitors at my primary desktop in portrait mode. Gnome accepts these settings just fine, but then the Gnome Shell activities menu (when activated) is a jumbled mess of partially rotated text and unrotated text. Boo...
The fix is to disable Wayland (for now) because X support still works correctly. Thanks to Google for helping me quickly find directions to disable Wayland.
- Edit the
/etc/gdm/custom.conf
- Under the
[daemon]
section, add a line that saysWaylandEnable=false
. - Reboot the computer (well, really you only need to restart GDM, but rebooting is pretty fast).
