Hello,
I just got IDL 8.2.2 installed (after an OS "upgrade" from RHE5 to RHE6)
and when I start it up I get the following error messages:
libGL error: failed to load driver: nouveau
libGL error: Try again with LIBGL_DEBUG=verbose for more details.
Google tells me this has something to with the video driver. Given that
I'm always grousing about Function Graphics display speed, I would like
to find out if my install has issues that will impact the FG display
improvements made in v8.2.2.
Any information/hints would be appreciated.
cheers,
paulv

Good to know! I've scheduled our sysadmin to install the nVidia driver
on my linux box.
Again, thanks very much.
cheers,

2D performance is good, but 3D is far behind:
"While the drivers include a significant amount of functionality and probably work on the common Linux games shipped with distributions, there are still some serious issues and they are not too optimized for performance. OpenGL applications that work at first may crash sooner or later. Some applications may crash X itself or hang the GPU. You should be prepared to face issues, and be able to recover from them yourself. If the GPU hangs, you can either reboot or suspend."

Excellent, thanks for the info Lajos.
One further question: do you, or others, know if using nouveau (ignoring
the errors) causes any performance issues, e.g. graphics are slower to
render sort of thing?
cheers,

nouveau is the open source nvidia driver. It was the default in my system (opensuse), too, and replacing it with the proprietary nvidia driver solved all the problems.
