I recently installed OpenSUSE 10.3 on a PC having Celeron 2+ Ghz, Intel 845 motherboard, and 512 MB RAM. I installed the required codecs to make kaffeine play .wmv files. The videos play alright in a small kaffeine window (window size is about 1/4th of my screen at 800x600 resolution). I've noticed that if I increase kaffeine window's size, RAM usage increases proportionally and video becomes jerky. This problem has intensified after enabling 3-d acceleration. The result is that I cannot view videos fullscreen without getting a pounding headache.
I had a similar problem on another pc with VIA chipset. Even Firefox scrolling was jerky. That problem was fixed after downloading and installing linux drivers from the motherboard manufacturer's website. But
http://intellinuxgraphics.org/download.html says that "If you have a 945 or older graphics controller, your distribution will already have the right drivers included."
Any pointers to solving the problem will be appreciated. I'm including my xorg.conf for reference. Just let me know if any other information is required and I'll post it ASAP.
