Re: [gl4java-usergroup] GL4Java Apps Make X "Go Away"

[David W. <da...@nt...>]

Same thing happened to me. Most of the samples freeze my X hard.
Remotely login to kill the X process is the only viable way to wake the
system.

Platform:
Pentium III 800
SuSE 7.3 Pro.=20
XFree86 4.2.0

ce the system is in this state you can't reboot, and have to power-cycle th=
e box to get its attention.  I'm really liking the ext3 filesystem right ab=
out now :-).
