Hello, folks.

I'm a newbie for linux.
Current linux version for ubuntu 8.10 is installed today.

A remote connection for server is established from local linux machine with "ssh -X @remote_machine". Then, when I'm trying to load the software in x-windows environment, the software and terminal are crashed, then log-in screen (the first initial screen after booting) is popped up.

libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering

I'm suspecting whether error message above should be critical to crash.
Would you please give me a piece of advice?
