Hi!

I just got my X800XL working in Ubuntu Feisty. Apart from AA performance in Blender it's really nice.

There is a nice guide on how to get two monitors running: link

Here is a fglrx manual. man fglrx doesn't work for me.

Here's part of my working xorg.conf. It enables Bigdesktop:

Code:

Section "Monitor"
	Identifier	"Monitor1"
	VendorName	"Generic"
	ModelName	"Flat Panel"
	Option		"DPMS"		"true"
EndSection

Section "Monitor"

EndSection

Section "Screen"

EndSection

        Device		"ATI Graphics Adapter2"
        Monitor		"Monitor2"
        DefaultDepth	24
        SubSection "Display"

        EndSubSection
EndSection

Section "ServerLayout"

EndSection

Section "DRI"
	Mode	0666
EndSection

Section "Extensions"
	Option      	"Composite"	"0"
EndSection

In the CCC AGP speed is 0. Should I worry about that?

The built in 3d screen savers are very slow (for example Hufo's Tunnel). Can I do something about this?

Regards,
Sladi

Are you sure that the screen savers are set to use GL as their rendering API?

By the way... you could try installing the fglrx package off of Synaptic package manager, or maybe Automatix supports it? Automatix worked wonders for my nVidia driver issues under Xubuntu 7.04
