Mutual GNU / Linux


Another Segmentation fault with fglrx driver.

When I try to launch Ryzom client (downloaded from ryzom.com), it crashes at loading screen with segfault.
It works fine with opensource drivers (libgl-mesa-dri and lidgl-mesa-glx), but computer behaves strangely with them and half of installed games don't work with them also.

So, i prefer stay with fglrx, but don't know how to pass through that segfault. There are backtraces from GDB:
