Hi
I have GRUB and Plymouth enabled. In addition, I have it a parameter in GRUB set to rotate the monitor for my vertical monitor (video=DP-1:panel_orientation=left_side_up). This, normally works fine.
However, I recently encrypted with LUKS. Plymouth now correctly shows up asking for a decryption password, however there is a significant visual glitch with what appears to be text-like lines across the right side of the screen. Additionally, I noticed earlier that when hitting ESC on Plymouth to show the text-based output when booting, the rotated monitor's output is just a bunch of garble.
I'm wondering if it is possible to either resolve this visual glitch somehow and have it show all output normally while vertical while maintaining the same Plymouth theme (bgrt), or simply just disable GRUB and Plymouth from outputting anything on the vertical monitor.
I have tried to do the latter by disabling the monitor with the following parameter (video=DP-1:d), however, this then completely disables the monitor in GNOME/GDM and no longer respects my display settings on the working monitor; I have tried to enable the other monitor in the GNOME settings, but that monitor doesn't show up, and my monitors.xml file still reflects my normal settings even with the monitor disabled, and again, the working monitor doesn't respect those settings.
Appreciate any help anyone is able to provide.
