--- Comment #25 from Zhiyi Zhang zzhang@codeweavers.com --- I expected XF86VidMode to work, but maybe it's just too old, and no one maintains it anymore. I did occasionally get X server crashes when I was migrating the XF86VidMode display settings handler to a new interface. Using XRandR transforms is indeed the correct way to go forward. It's similar to the fullscreen hack currently used by Proton.
