Slow rendering under Linux (was: Re: node highlighting)

Hi,

First, when starting a new thread, please don't just reply to an old 
one, since it can be confusing.

As for the slowness, check to make sure your GL support is set up 
correctly under Linux. I have had experiences where on one ATI card my 
GL wasn't working, (when I'd render only the window frame would show up 
but no image rendering), but on another ATI and an nVIDIA card 
everything was fine. On Windows the vendors supply GL drivers, but on 
Linux their attempts can be very half-hearted, at best. Look for any 
GL-based apps on your system and if you have a problem running those, 
this is your problem. TuxRacer is a good test because most distros 
include it these days.

Also, I've noticed problems where one Blender version was really slow 
and I downgraded to the just previous version which was about 2x as 
fast, so see if you can check CVS for a latest update, there may have 
been something with your version that had an incompatibility with 
something in SUSE.
