Re: ati driver & xfree86 [solved]

Hi !

Finally fixed the problem : accelerated X is running :-)

Here's the working "Device" Section : this may help people with older 
ati cards to get acceleration working (it is the trouble worth)
The trick was to change the reference clock : look at
http://www.xfree86.org/support.html, especially the
"ATI Adapters README file" for your release

Section "Device"
        Option     "accel" "true"
        Option     "crt_screen" "true"
        Option     "hw_cursor" "true"
        Option	   "dpms" "true"
        Option     "reference_clock" "29.5MHz"
        Option     "shadow_fb" "false"
	Identifier  "XClaim 3D Plus"
	Driver      "ati"
	VendorName  "ATI"
	BoardName   "Mach64 LI"
	ChipSet     "ati"
	# The following is from X -configure
	ChipId      0x4c49
	ChipRev     0xdc
	BusID	   "PCI:0:14:0"
EndSection

Good luck,
Simon
