Hi, I'm using the vesa driver for the amd/ati hd3200 (780G) chipset (Gigabyte GA-MA78G-DS3H mobo). The problem I have is extremely heavy CPU use by Xorg, whenever any action is done (move a window, open an application, watch a dvd, etc). CPU use may go beyond 100%. I don't use Compiz or any 3D stuff. I mean, I am doing just usual plain 2D work. The problem is worst in KDE 3.5 compared to Gnome.
Please can you explain me: is this due to lack of 2D hardware acceleration by the vesa driver?
The vesa driver provides no acceleration at all. You are also limited to the mode list supported by the bios. It's basically a fallback driver.
