i just fixed something like this on ubuntu 7.10 with an ati radeon x600.  the latest drivers run on aiglx which conflicts with the previous versions which run on xgl.  this sometimes even caused X to crash when running tksurfer and even glxgears.

on my system this was resolved by simply removing the package xserver-xgl.

there should be no reason to uninstall the proprietary fglrx driver.

Does glxgears work?  That is an app that comes with Linux that exercises
the GLX (OpenGL X extension) code.

Dear FS experts,

I install CentOS 5.1 and latest version of ATI driver and FS4.0.2,
when I start tkmedit, it looks fine. In tksurfer, it just appear a
sliver of surface without error message. In console, it stock on
reading vertex.

Is there anyway to correct it ?

Thanks replay
