Hi there. I've got a Gateway MT6452 laptop with an ATI Radeon Xpress 1150. I'm running Ubuntu Intrepid. Fglrx really stinks, for various reasons (video on compiz, zsnes, others), so I use the open source radeon driver. I'm trying to tweak it for extra performance.

Here's my xorg.conf, device section:

Code:
Section "Device"
	Identifier	"Configured Video Device"
	Driver		"radeon"
	BusID		"PCI:1:5:0"
	Option		"GARTSize"		"32"
	Option		"AccelMethod"		"EXA"
	Option		"EXANoOffscreenPixmaps"	"on"
	Option		"ColorTiling"		"on"
	Option		"BackingStore"		"on"
	Option		"EnablePageFlip"	"on"
	Option		"RenderAccel"		"on"
	Option		"SubPixelOrder"		"NONE"
EndSection
I've also installed DRIconf, but I can't make sense of most of the options. I've only disabled vsync there.

Is there anything else I can do to improve performance? Also, how do I add extra resolutions? Adding display subsections in the Screen section doesn't seem to work for Intrepid.
