So the issue is the false SVIDEO detection then. The g4x silicon was
quite flaky with its TV detection, but I thought we had it stable now.
Firstly: does your hardware even have an SVIDEO connector (composite out)?
Can you please attach the drm.debug=6 dmesg from boot so that we can see the
debug output for connector initialisation (basically to see what the BIOS says
is on the machine)? One answer may be just to quirk your machine to stop it
claiming it has SVIDEO in the first place, as the false positive in the
detection could easily be due to a floating pin on the motherboard.
** Changed in: xserver-xorg-video-intel (Ubuntu)

** Summary changed:
- [GM42] Screen flickering on login and boot screens on 8086:2a42
