Bug description:

On a Asus Mini Barebone (Pundit P3-PH4C SK775 DDR2) with 945G chipset, the monitor connected on the VGA port is not detected and the X server therefore exits with "Fatal server error: no screens found". Normally a Samsung TV (LE27S7) is connected via a VGA cable, but also when an Eizo CRT was connected, it is not detected. Both get-edid and ddcprobe is able to read the EDID of the monitor. When using the vesa driver it works normally.

It used to work in ubuntu 8.04 (which has intel driver 2.2.1), but stopped working in 8.10 (with driver version 2.4.1). It has been tested and found not to work in 2.7.1. While the default AccelMethod for ubuntu packages (including 2.7.1) is EXA, it has also been tested with UXA without working.

System environment:
-- chipset: 945G
-- system architecture: 32-bit
-- xf86-video-intel: 2.7.1
-- xserver: 1.6.0-0ubuntu14
-- mesa: 7.4-0ubuntu3
-- libdrm: 2.4.5-0ubuntu4
-- kernel: 2.6.28-11-generic
-- Linux distribution: Ubuntu 9.04 (Jaunty)
-- Machine or mobo model: ASUS PUNDIT P3-PH4C SK775 DDR2
-- Display connector: VGA
