Bug#612609: upgrade to 7.10-3 disables composite effects

[Stefan <bugs.debian.org@kanarski.de>]

Hello,

I have a similar problem with 3D acceleration.

With libgl1-mesa-dri 7.10-3 I get the following in /var/log/Xorg.0.log

[    13.283] (EE) AIGLX error: Calling driver entry point failed
[    13.284] (EE) AIGLX: reverting to software rendering
[    13.284] (II) AIGLX: Screen 0 is not DRI capable
[    13.297] (II) AIGLX: Loaded and initialized /usr/lib/dri/swrast_dri.so
[    13.297] (II) GLX: Initialized DRISWRAST GL provider for screen 0

while with 7.10-2 I get

[  6657.952] (II) AIGLX: enabled GLX_MESA_copy_sub_buffer
[  6657.952] (II) AIGLX: enabled GLX_INTEL_swap_event
[  6657.952] (II) AIGLX: enabled GLX_SGI_swap_control and 
GLX_MESA_swap_control
[  6657.952] (II) AIGLX: enabled GLX_SGI_make_current_read
[  6657.952] (II) AIGLX: GLX_EXT_texture_from_pixmap backed by buffer objects
[  6657.953] (II) AIGLX: Loaded and initialized /usr/lib/dri/r600_dri.so
[  6657.953] (II) GLX: Initialized DRI2 GL provider for screen 0


But maybe it's not quite comparable to Michael's problem since I am using a 
newer kernel and another ATI graphics card on a DELL Precision M6500:

I was very curious about the new Gallium driver but until it works I will stay 
with 7.10-2. Maybe "Calling driver entry point failed" points someone into the 
right direction if it's related to the original problem at all. Thanks for the 
good work it's very appreciated.

Best regards
Stefan
