Thank you very much for describing and discussing this workaround :-)
I was able to get good graphics with Saucy alpha 2 in my old IBM
Thinkcentre desktop computer, that has suffered from bad graphics since
Raring. I used your workaround, John, and it worked without issues with
the log in screen.
My Thinkcentre has the following graphics
VGA compatible controller: Intel Corporation 82865G Integrated Graphics
Controller (rev 02)
I'll attach two text files for clarity, one with the tips explicitly
stated, and one with the output of lspci on my Thinkcentre.
I used the installed system for USB according to the following link
I don't notice the bad graphics with my wall-paper (for Saucy alpha2),
but switch to the default one, and you see it! After adding uxa
acceleration, the default wallpaper is rendered as it should, without
the sharp boundaries, 'jagged' as described by Aere concerning the
I found also this link about UXA for Intel graphics
Where could this workaround be added into the Lubuntu Wiki?

There was this helpful bug report on file at http://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178982.
It described behavior on Dell PC's with integrated Intel graphics, in which Adobe Flash Player would display only with shades of purple and green in a horizontally compressed window (or at least that's how I would describe what I see on a Dell Dimension 2400).
The work-around (Comment #1) was to change the Xorg acceleration method to UXA.
User reported a work-around:
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).
Identifier "Intel Graphics"
Option "AccelMethod" "uxa"
Restart X (reboot, restart your display manager, whatever). Colors are back to the way they used to be and flash works.
I forgot to include, however, that the bug workaround messes up the login screen (LightDM). You can make out an entry box that one assumes is for the password entry, but everything else is largely unidentifiable.
So as a workaround it leaves a lot to be desired, unless we can also figure out how to fix the login screen.

There is no issue with the login screen.
