Public bug reported:
after recent updates I get this bug periodically. X display disappears and is
replaced by error-log output; in the log I see this message:
[drm:drm_mode_getfb] *ERROR* invalid framebuffer id
switching VT's restores the display, but this behaviour repeats on
average about every 10 minutes.
Around the same time I started having problems with hotkeys as well -- X
hijacks Alt-Fn and Alt-Tab as though they wre Ctrl-Alt-Fn and Ctrl-Alt-
Tab - reporting that now in a separate bug but noting here in case it's
related.
