A nice performance tip for 2D

[vrodic]

Hi

I recently found that firefox can be a lot faster when Option "XAANoOffscreenPixmaps" "true" is present in device section of your xorg.conf.

Thank you! This worked for me on an Ubuntu 7.10 with 1800XT Cat 8.01.

I found also a few details on cchtml.com wiki (http://wiki.cchtml.com/index.php/Performance_Issues)

i have to admit - it works. i have a reason to risk using exa again ;-)

at least those js-heavy pages don't slow firefox to a crawl anymore. i didn't expect that it would be a driver/xorg issue.

thanx!
with this on my 2d speed is pretty much ok
(had it commented out when i installed 8.01... redraws were tragically slow... what's strange is that in the previous drivers i didn't notice any impact on the performance by turning this option on/off)
anyways...thanx again!
(btw, any other cool options for xorg.conf?)

Keep in mind that this option disables almost _all_ hardware accaleration. It may be a short-term solution but a real solution would be to write AMD (and also NVidia but their render support is better) that they should implement support for XRender accaleration.

is there a list or something with the available xorg.conf options and what they do?
