Bug Description
Binary package hint: xserver-
On current hardy with chipset and video card:
00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c)
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
With xorg (1:7.3+10ubuntu4) and intel driver (2:2.2.
- 2D acceleration is utterly slow, especially when Compiz turned on. For example vertical scrolling in firefox is unacceptable slow. Even with compiz disabled it is remarkable slower than with XAA
- when having a virtual display (even below or equal to 2048x2048) with multiple display devices (regardless of clone or extended mode), the whole system hangs if a 3D application is used
