Subject: [PATCH] udev: Allow wayland on hybrid vendor nvidia machines
|
||||
|
||||
We currently disable wayland on machines with the vendor
|
||||
nvidia driver upstream if hybrid graphics are in place because there
|
||||
is poor performance for multimonitor use cases.
|
||||
|
||||
But springing that change on users in F37 this late in the game
|
||||
isn't nice, so instead default to Xorg and provide wayland as an
|
||||
option in the menu.
