old intel graphics works better (without uxa acceleration tweak)

[Nio Wiklund]

Hi everybody,

Old intel graphics works again (without the uxa acceleration tweak), at
least it works better from pictures.

Somewhere along the development path of Trusty, it started to render
pictures well again, for example the background picture of Lubuntu.

Those of us who had problems in Saucy and also in the beginning of
Trusty have fixed it with the uxa acceleration tweak (introduced to us
by John)

Edit (or create) /etc/X11/xorg.conf as follows: (ugh, can't format,
should be a tab before each line except the first and the last).

Section "Device"
	Identifier "Intel Graphics"
	Driver "intel"
	Option "AccelMethod" "uxa"
EndSection

This is not necessary in the current daily build in our IBM Thinkcentre
with the following Intel graphics:

VGA compatible controller: Intel Corporation 82865G Integrated Graphics
Controller (rev 02)

-o-

But there is another problem too. Video clips are rendered with too
bright colours. This problem appeared at the same time as the jagged
contours in pictures. And this problem remains in our Thinkcentre.

I suggest that you try too, if you are/were affected by this regression.

Please check the rendering of pictures (jagged contours) and also
playing video clips (which might have too bright colours) and let us
know how it works for you!

Best regards
Nio
