Updated and Optimized Ubuntu Free Graphics Drivers
But after I reboot after setting my xorg.conf to use Glamor, I'm presented only with a black screen, with a mouse pointer on it. It's almost as if Xfce isn't loading fully or something.
Just a quick question though about the Device section. Would I need to add another device section and somehow specify both devices in a dual graphics setup for glamor? Or does the Device section cover all devices?
And also a general question; if I start 3D applications with DRI_PRIME=1 (my dGPU), they don't actually show anything at all if I have Xfce set to use no composting. If I enable composting though, the applications show up. Any ideas why, or what I could do to fix this (I don't want composting; I only want performance essentially)

Ok glamor start with kubuntu 13.04 , but rendering windows (only kde) works bad.
Hi, Vincenzov. What compositor backend are you using? I am using OpenGL 2.0 with raster and although I occasionally see some corruption on windows, it only happens on few ocassions and (and it seems that only with certain programs such as the KDE sytem settings screen and gwenview) it can be corrected by minimizing and restoring the windows. I would suggest that you try that compositor backend if you're not already using it.
Not sure about the difference, but when the Steam linux client was published I remember there was a recommendation to run KDE with raster. Otherwise Steam menus would not show correctly. I am not sure if that was corrected but in any case with radeonsi native gives quite a lot of glitches, at least for me.
On the other hand, I am quite happy with OpenGL 2.0 raster.
OK work good opengl 2.0 and raster, for video i use gl_tiled with mplayer. Now i try use radeon 7750.
Out of curiosity, why don't you use vdpau UVD with mplayer? It works great for me. You need to edit ~/.mplayer/config in order to add the following (or replace the existing configuration you may have regarding video output -vo- and video codec -vc-):
