[xcrysden] swrast driver error

You might have a look at the webpages:

 From what I see at those links, that "libGL error: failed to load 
driver: swrast" error seems to be due to a video card driver issue.  It 
looks like some had to uninstall and reinstall the video card driver or 
reinstall/upgrade the OS version.
