Comment 11 for bug 127008

In my system the TV output is already disabled (without the above lines in xorg.conf). Running xresprobe intel does not give the colored blocks.
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA disconnected (normal left inverted right)
LVDS connected 1280x800+0+0 (normal left inverted right) 331mm x 207mm
   1280x800 59.9*+ 60.0
   1280x768 60.0
   1024x768 60.0
   800x600 60.3
   640x480 59.9
TV disconnected (normal left inverted right)

I did find something in the logfiles: the installation uses framebuffer and loads modules fbcon and vga16fb (+ some depending modules). My installed system does not use these modules.

When I do the installation without any additional boot option, I get the colored blocks
when I do the installation with boot option vga=771 or fb=false, I don't get the colored blocks.
Could this mean the problem is caused by using framebuffer with the intel driver?

I also found a way to reproduce the problem manually: I don't answer the question about language support in the installation but switch to tty2. When I just install xresprobe and xserver-xorg-video-intel manually, the colored blocks show (no boot-option).
Could I retrieve more information by doing this manual install with some special options?
