Speeding up X on FireGL V5250
Hey all. I've got a Thinkpad T60p with a FireGL V5250 card. I know from using XP on this machine that this a very capable video card. The performance I'm seeing with the radeonhd driver just isn't great - slow scrolling in Firefox is the most obvious problem. Right now it appears that I'm using XAA judging by my Xorg.0.log: (**) RADEONHD(0): Selected XAA 2D acceleration. I've read on this list that XAA is known to be slow and that ShadowFB is better. So far I can't get ShadowFB to work. I've added this line to my xorg.conf, in the Device section: Option "ShadowFB" "on" But I see this in my logs: (WW) RADEONHD(0): Option "ShadowFB" is not used Can anyone give me any advice on speeding up X with my card? Am I barking up the wrong tree with ShadowFB? In case it helps, I'm running fully updated Fedora 8 with the radeonhd driver v1.1.0 from the xorg-x11-drv-radeonhd yum package.

Hi Sam, I've got a v5200 (slightly older but mostly the same) chip in my T60p, and here's what I've got in the "Device" section of my xorg.conf: Section "Device" Identifier "FireGL5200" Driver "radeonhd" Option "monitor-DVI-D_1" "DoubleSightDVI" Option "monitor-PANEL" "ThinkpadLCD" Option "RROutputOrder" "DVI-D_1" Option "AccelMethod" "shadowfb" EndSection The last bit is what it took to get my shadowfb rolling, I've got # Option "ShadowFB" "on" in there but commented out so it must not have worked. Anyway, things are quite nice in 2D with ShadowFB, and I'm being patient for 3D acceleration for now (I reboot to windows to play games anyhow :) Alec -- Alec Habig, University of Minnesota Duluth Physics Dept. habig@neutrino.d.umn.edu http://neutrino.d.umn.edu/~habig/ -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

you want: Option "AccelMethod" "ShadowFB" Alex -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

Excellent. In thanks I'll see if I can cook up a patch to the man-page to this effect. -sam -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

Looks like someone beat me to it. The latest man page in git says the broken option is described as "deprecated" and the one that works "is considered to be more flexible." Not perfect but it certainly would have put me on the right track. -sam -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

Interesting to know that the old method doesn't work any more... It
actually should.

It's possible it does in the latest sources. I'm running v1.1.0 in Fedora 8. If I get around to installing the latest from git I'll test it and see if both work. -sam -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

Please let the list know, I'm interested in this; we may want to set ShadowFB to be the default in Mandriva if the upstream default doesn't work in current git. -- adamw -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

If it doesn't, it should certainly be fixed before the next release.
I don't like nuking deprecated options *that* fast ;-)

Thanks, but it's kinda edgy for MDV - we've technically been in version freeze for about two weeks, I can only upload new git snapshots with no trouble because they don't actually count as 'new versions' in our package naming system =) so I'm not sure whether we'll move from our current git snapshot before release. If I see commit changes logged "fix gigantic bug in $FOO" then I will, but if not, maybe not. -- adamw -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
