Hi, My F19 has suddenly become very unstable. After about 10 minutes of running with KDE, the opened windows start to be closed automatically. I even cannot stop the machine. I have access to the fedora menu but its rendering is very odd and clicking on shutdown does not do anything. I cannot go to a terminal either (with konsole which I cannot start or with Ctrl+Alt+F2). I have noticed that if I start the computer and just wait at the login screen of kdm, the keyboard start to not work when I try to type my login. I do not know where to look at to find the cause of this. My F19 is uptodate, with kernel 3.11.7. I have tried to boot with 3.11.6 but experience the same issue. I have a nvidia video card but I do not use the nvidia driver, the nouveau one provided by F19 instead.
