Hi.
Xorg froze while playing a game with wine. Only the mouse worked (not even the keyboard). I had to hard reboot.
Checking out the logs (journalctl) I saw repetitive nouveau errors. (sorry, not at home, else I´d post them).
Other times I have been able to ssh into my machine and everything else is working. I did not try this time (my secondary machine is down for the moment).
My question is: How can I restart the Xorg server and/or the nouveau driver? If I could ssh into the system, I think I could just restart both and not have to reboot the whole thing. It is more annoying that anything else because the machine boots fast, but still I think it should not be necessary.
Just polishing my skills.
Thanks

Next time you're logged in and things are working, go into the keyboard preferences, and delve through the keyboard layout options. There's a hotkey, that's traditionally CTRL+ALT+BACKSPACE to restart X, but has been disabled by default, for quite some time. It's one of the first things I re-enable on new systems.
If remotely logging into a stalled system, run the "top" command and find Xorg, you could try killing it. I used to do something like switch to runlevel 3 (command line only), wait for that to complete, then switch back to runlevel 5 (GUI). There's probably other ways, too.
