The polytopes screensaver slows down an entire order of magnitude when /etc/X11/xorg.conf specifies UXA acceleration instead of the default EXA Reproducible: Always Steps to Reproduce: 1. Configure X to use UXA acceleration 2. Go into X 3. start the polytopes screensaver Actual Results: Enabling UXA caused a HUGE slowdown Expected Results: UXA would be faster as it's a newer standard and even recommended by gentoo-wiki on the page for Intel GMA. Relevant software versions: sys-kernel/gentoo-sources-2.6.31-r6 (KMS) x11-base/xorg-server-1.6.5-r1 x11-misc/xscreensaver-5.10 Hardware: Intel Atom 330q Intel 82945GC integrated graphics card xscreensaver: /etc/X11/xorg.conf: Autogenerated by X -configure Added following line to the driver section: Option "AccelMethod" "UXA"
Since you provide almost no valuable information, I'll try some guessing. Judging by the few version numbers you posted, I'd say you're running stable x86 or amd64. So that would mean you're running either xf86-video-intel 2.8.1 or 2.9.1 (hopefully, the latter). Since EXA support was completely removed between 2.7 and 2.8, you're actually not using EXA at all, you're using software fallbacks. If you have a good CPU, chances are it'll run faster than the GPU (the 945 isn't really a speedy GPU). In any case, please attach your Xorg.0.log with _and_ without UXA enabled. Thanks
Sadly, config shuffling has since destroyed the requested information. Closing.
Reopening to close the proper way.
Per some assistance I received on the forums this was a simple case of improper permissions on the card01 device.
