When nvidia kernel module is not blacklisted system can't be booted properly with X server: display hangs while loading display manager, but system is accessible via ssh and there's no error messages in the log files. The strange thing is that I can boot and start display manager if nvidia module is blacklisted and later loaded by xorg server. With this workaround I can login and everything works just as expected. However, when I try to logout the display goes black (keyboard doesn't works except SysRq keys), but system is accessible via ssh or somehow else. While system hangs in the way described above I can see following s uspicious things: - the X server process is waiting for disk (status Ds+) - it's not possible to kill the X server process (using any signal) I'd appreciate if somebody would give any hits on how can I investigate this problem any further. Thanks in advance, Vlad.
