glxgears window solid black, graphics very slow

kernel_geek · 2011-03-24 19:10:22

Hello,

I have rather a strange X setup; 2 monitors are connected to an ATI card running the radeon drivers, and the third is connected to an NVIDIA, running the nouveau drivers (because nvidia glx stuff clashes otherwise)

I have achieved this using a messy xorg.conf and Xinerama, thus disabling composite and RANDR.

I do however have some performance issues:

1. Unfortunately the 2 monitors that are connected to the ATI card are slow; dragging windows is laggy, and leaves a 'shadow' behind, especially between monitors.

2. Opening glxgears works fine, but only on the left hand monitor; dragging the window to either the middle or right hand monitors results in the gears disappearing and being replaced by a solid black box.

3. The monitor connected to the nvidia card seems quicker, but displays some artefacts, things like terminal transparency only working on certain areas of the screen.

As a side issue, is there anything obvious that could be responsible for a slightly slower machine?

Things like logging in and 'pacman -S foo' seem to take a few seconds longer than they used to, on a relatively fast machine (quad core, 4gb ram).

xorg.conf:
