I am trying to run my java app on ubuntu server, but i constantly receive this error: java.lang.InternalError: Can't connect to X11 window server. I set the DISPLAY variable to :0.0 but that didn't help. In the X11 log file i got these error messages: (EE) open /dev/fb0: No such file or directory (EE) intel(0): No kernel modesetting driver detected. (EE) Screen(s) found, but none have a usable configuration.

do you have an X server running on :0.0? And is the user authorized to use it (xauth)? – mulaz Dec 6 '12 at 12:22
Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable. I am logged as root – flux_relux77 Dec 6 '12 at 12:26

yes, but is the actuall X server running? – mulaz Dec 6 '12 at 12:30
no, i cannot start the X server – flux_relux77 Dec 6 '12 at 12:37
I'd suggest you look at the stack trace, figure out what class is throwing the error, and find its source, to understand why the error is occurring. – Daniel R Hicks Dec 6 '12 at 12:56
