Since some time my main Linux box won't continue booting to the graphical login manager unless I hit some random keys (any will do) on the keyboard. I guess there is some service asking interactively for something, but I can't see any prompt (maybe swallowed by systemd, who knows). Since some time switching VTs resets all hardware accelerated applications (i.e. crashes them). Since some time unlocking the graphical session is randomly broken and requires loginctl session-unlock from another VT (which then promptly triggers bug 2). These things keep coming and going... it's not even Linux-specific. Stuff just breaks all the time and you shrug and move along, hoping that maybe someday it's fixed. For most of these I wouldn't even know who should receive a bug report. Maybe it's the graphical login, maybe the compositor, maybe mesa, maybe a kernel driver, maybe systemd, maybe maybe...
