Full log using compiz as gl-based wm
If try to start any WM that uses GL(Compiz, Gnome-shell, etc...) i get screen
completely stained and a lot of r300 error in .xsession-errors
Attached full log (using compiz)
Detail: if only one monitor is connected this error/bug doesn't occur and WM
GL-based start correctly.

As per your log, you've exceeded the hw limits of the 3D engine on your chip (max texture size of 2048x2048). /usr/bin/compiz (opengl) - Warn: Bug in window 0x1600016 (identifying as desktop_window) /usr/bin/compiz (opengl) - Warn: This window tried to create an absurdly large window 2646 x 1024 /usr/bin/compiz (opengl) - Warn: Unforunately, that's not supported on your hardware, because you have a maximum texture size of 2048 /usr/bin/compiz (opengl) - Warn: you should probably file a bug against that application /usr/bin/compiz (opengl) - Warn: for now, we're going to hide tht window so that it doesn't break your desktop
Ok, if i use Xinerama (with same resolutions) will exceed hard= ware limit or not ?

If you want to use 3D effects across a desktop larger than the hw limits of the GPU, you either need a newer GPU with larger hw limits or someone has to make major changes to the xserver to allocate separate surfaces for each monitor rather than a single large surface for all monitors.
