nanogui: Thread: GrCopyArea problems with SVGA Nano-X

Hi guys,
I was seeing a strange problem last night, whilst running with a SVGA
based Nano-X server the GrCopyArea was failing to copy anything.
 
I switched to a frame buffer based server and ran the same client code, 
which seemed to work OK. Unfortunately I was then informed of the time ;-)
 
 
Can someone else confirm that SVGA is on the blink.... the demo 'slider.sh'
should use a graphic (rather than numbers) by default, so just run that.
 
 
I tried with CVS and 0.98pre7 versions, but got the same result.
 
The only other thing is that I'm running at 640x480, as my little laptop gets 
rather confused by 800x600. Forced by adjusting scr_svga.c

Did some hacking around at the weekend, and I can confirm that GrCopyArea
will not work with SVGA as a memory->screen blit is not supported.

Does anyone actually want this fixed? 

Or would I be wasting my time attempting to get it going....

Simon,
    That would be great.  When I wrote the original
driver, I didn't have time to finish the SVGA mem->scr blit,
but others have used SVGA driver and don't get the 
full functionality.  Another use of the SVGA driver is to have
a separate non-fb based driver to test our functionality
with.
