Hi all, here some more informations. maybe it helps:
1) Purging flashplayer doesnt solve the problem 2) You still can login by network when graphic hangs 3) Xwayland process uses 100% CPU 4) Connecting to this process with strace shows only a lot of: writev(16, [], 0) = 0 regulary interrupted by: --- SIGALRM {si_signo=SIGALRM, si_code=SI_KERNEL} --- rt_sigreturn({mask=[]}) = 0 5) A restart/stop of gdm (systemctl restart/stop gdm) doesnt help, you have to do a hard kill (kill -9) of the Xwayland process.
