Glxinfo throws error "failed to load driver: swrast"

Post by Somujit » 2013/05/28 14:19:10

Hi,

I have installed the freeNX tool on a CentOS 6.4 box and used NX client from windows to connect to it. This helps me open up a session (much like how XVnc does) on the CentOS box [let's call it centos1]. So, once I open up a session and run 'glxinfo' on a terminal, this is what I see:

[user@centos1 log]$ glxinfo

The two lines that disturb me the most here, are:

libGL error: failed to load driver: swrast
libGL error: Try again with LIBGL_DEBUG=verbose for more details.


Could one of you point out what might be going wrong here? I believe this has something to do with the swrast 'driver' and am not sure how to fix it.
