GLX Info: NOT Using destination window

I have an aging system here that I just installed Ubuntu 7.1 on and successfully compiled xbmc on it. That is, it compiles, but doesn't really run all that well.
Debug info shows 1.7 FPS and mouse response is extremly slow (to the point of being unusable). Is this all due to lack of OpenGL 2.0 support ?

CPU: P4 1.6Ghz
Memory: 512MB
GFX: Silicon Integrated Systems [SiS] 65x/M650/740 PCI/AGP VGA Display Adapter
glxinfo indicates that I the card supports Open GL 1.4

These lines in xbmc.log look related:

I'll be more than content if I get an answer like "you'll never get xbmc to run with that hardware". It'll just tell me to stop fiddling with this old piece of crap

I should add that I can play 720p movies through VLC without problems (25% cpu utilization) on this box.

XBMC requires an opengl 2.0 compliant videocard. You can pick one up for like thirty bucks. Not sure if it'll handle 720p, though-- I don't think anyone has tested XBMC/linux on such a low-end CPU.

I have a couple of cards here that are opengl 2.0 compliant. Problem is they're AGP and this low-end pc I'm fiddling with only has pci slots (not pci express)... Oh well, I'll but this system back on the shelf for now

Newegg has a PCI geforce 5200 for $35 and a 6200 for $61. The 6200 will definitely work, not sure about the 5200. It is technically directx9 compliant, shader model 2, etc, so it should support opengl 2.0, but the geforce 5 series were pretty crappy.

SandmanCL, it appears that your OpenGL drivers are Mesa. There is a decent likelyhood that you are running software OpenGL which is not hardware acceleration. You can confirm this by running 'glxinfo' and looking at the first few lines of the output. One of them will say 'Direct rendering'. Ideally it should say 'yes'. If not, you're not getting any hardware acceleration from your graphics card. Other than upgrading, your other option is to try to determine if you graphics card has any accelerated drivers under Linux and install them.

P.S. - Even if you find accelerated drivers, I don't think you'll get usable performance with that SiS card.

P.S. 2 - The NOT using destination window message is not an error, although it sounds like one.
