1. default EXA accel.,no further setting:
Xv without compiz: fine
3D app: kernel hang
compiz: works, but some effects are broken (e.g. border shadows)
Xv with compiz: _slow_, unusable
2. XAA accel.,no further setting:
Xv without compiz: fine
3D app:
compiz: works, seems faster, no broken effects
Xv with compiz: doesn't work ( X11 error: BadAlloc (insufficient resources for
operation) )
3. default EXA accel.,INTEL_BATCH="1":
Xv without compiz: fine
3D app: works
compiz: works, but some effects are broken (e.g. border shadows)
Xv with compiz: _slow_, unusable
4. XAA accel.,INTEL_BATCH="1":
Xv without compiz: fine
3D app: kernel hang
compiz: works, seems faster, no broken effects
Xv with compiz: doesn't work ( X11 error: BadAlloc (insufficient resources for
operation) )
I haven't experienced any effects of the INTEL_BATCH option. Although with EXA
there are broken effects with Compiz.
Is there no way to get the Xv playback working with compiz?
How to reproduce the kernel hang with the 3D app:
Attach a second monitor, and set your screensaver to "Queens".
Now lock you system. The screensaver should start on both screens. It seems
slow and laggy, but works until you don't move you mouse or press any key.
In this moment, when the password dialog should pop-up to unlock your screen,
the displayed screen freezes and the system does not respond to any event.
This crash doesn't happen if I have only one display attached or I just
start the screensaver preview. In this cases it is also faster and
doesn't lag.
I guess I shall open a new bugreport for the latter.
