Ubuntu, Fix Lagging on SIS Video Card
Many AMD64 and AMD Sempron platform uses SIS chipset. For example, the Acer Aspire product line which use AMD technology. This integrated video card often cause lagging problem on the fresh installed Ubuntu. (Ubuntu Lucid and Ubuntu Jaunty). If you see delay when dragging your window or when watching YouTube video, there is a good chance to fix it by using "vesa" driver for your X server.
First, generate your xorg.conf. So Ubuntu will use it.
Second, in your xorg.conf, change "sis" to "vesa" in your driver section.
vesa driver might not fully utilize the potential of sis chipset, but it usually works better than the sis driver.
