[compiz] radeon or radeonhd or xf86-video-ati ( was Re: Will radeon or radeonhd work with compiz?)

The fglrx driver is typically faster than either open source drivers in 3D, but I'll take the performance hit over a binary blob any day. I noticed in your logs you are using XAA, you can see if switching to EXA makes any of the issues go away. Alternately, theres the xf86-video-ati driver you can try as well. It shares a lot of code with radeonhd but sometimes it works better. Wil Wil, You got me here. What do you mean EXA v. XAA? How do I change to test? I have tested both the radeon and radeonh drivers and can't tell much of a difference, if any. You also suggest trying the xf86-video-ati. Is it supposedly faster than the radeon and radeonhd drivers? I'll poke around some more, but if you have a few extra bits of info on it, I'd appreciate it. Thanks. -- David C. Rankin, J.D.,P.E.

XAA EXA are the 2 different acceleration methods for most X drivers. Intel additionally has UXA, but its based on EXA.I don't know about the radeonhd driver, but the ati one defaults to XAA even tho EXA generally provdes better performance these days (the commit has been made to change the default to EXA in git, its just not released yet). Just add a line like Option AccelMethod XAA or Option AccelMethod EXA to the Device section in your xorg.conf file to change between them. /var/log/Xorg.0.log will confirm what is getting used. Wil Got it! Thanks. I'll give it a go and report back. -- David C. Rankin, J.D.,P.E.
