Comment #1 in the bug report
(<a class="moz-txt-link-freetext" href="http://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178982">http://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178982</a>) does
work. On my system there was no existing /etc/X11/xorg.conf, so I
created it and added the specified lines as the sole content of the file.
The colors and the proper window size were restored. This Dell has an
Intel 845G chipset, so this workaround may fix this problem on any
motherboard with the same chipset (or even other Intel chipsets that
use the same Intel driver).
------------------------------------------------------------------------
Verging strictly off-topic, but remaining with the question of getting
Flash to work decently well:
On this former XP machine with a Celeron 2.4 GHz and 1 GB RAM, YouTube
videos in the default window size and playing at 360p seemed to
perform normally. Likewise, video from Hulu can be set to a lower
quality to help assure continuous play. But video from Vimeo can only
be set to HD-Off (if HD is available). And with video from the
broadcast network sites CBS.com, NBC.com and ABC.com, you can only
change screen size. So it seems that videos from Vimeo, CBS, NBC and
ABC offer very little accommodation for lower-spec setups. And
relatedly, I find that video that plays OK on a Windows PC with a dual
core Intel E2200 @ 2.20 GHz -- even with just 1.3 Mbps download on my
DSL service -- plays badly on the 2.4 GHz Celeron using the same
Internet connection. So in this case processing power is more
important than Internet connection speed.
2.4 GHz is the minimum required spec for Flash (the last I knew), but
perhaps that merely means that you'll be able to play *something*
(like YouTube or Hulu videos at a lower-quality setting), not that
you'll be able to play everything.
Does anyone know if there is a way to lower the quality settings for
sites like Vimeo, CBS, NBC and ABC, even if there is no
quality-setting tool in the player interface? (Or does anyone differ
with the assessment I offer above?)

Thank you very much for your reply.
There's a lot of really good information in it.

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
<a class="moz-txt-link-freetext" href="https://help.ubuntu.com/community/InstalledSystemFakePAE">https://help.ubuntu.com/community/InstalledSystemFakePAE</a>
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
Raring wallpaper.

I found also this link about UXA for Intel graphics

@ Phill:
Where could this workaround be added into the Lubuntu Wiki?

I'm trying to find a workaround for the workaround and fix this
garbled login screen.<br>
<br>
But to round out the knowledge of the problem and solution, I
observe that uxa acceleration solved a different problem for Nio
than the one I was first addressing (with Flash content displaying
in green and purple in a compressed window). Nio wrote:<br>

<br>
And to pick out another bit worth noting, he observed that uxa
causes no problem with the login screen, but his case deals with
Saucy alpha 2 rather than Raring, so I merely underline those
particulars.<br>
<br>
So now I'm wondering how uxa fouls up the LightDM login screen on
Raring but not on Saucy. I'm hanging on by my troubleshooting
fingernails here looking for clues, but <a
href="https://en.wikipedia.org/wiki/LightDM">https://en.wikipedia.org/wiki/LightDM</a>
notes that LightDM "uses various front-ends to draw login
interfaces, so-called Greeters."<br>
<br>
The apparent Greeter of interest here is the GTK+ Greeter.
Following the the references in the LightDM wiki, I see that 12.04
used lightdm-gtk-greeter (1.1.5-0ubuntu1). 13.04 uses v
1.5.1-0ubuntu1 of the Greeter (and v 1.6.0-0ubuntu3 of LightDM).<br>
<br>
What version of the Greeter is Saucy using?<br>
<br>
Are there some LightDM/Greeter settings I can play with to see if
any of them yields a clean login screen? Or can we compare some
Raring vs. Saucy configurations and learn something useful?<br>

And closer to the original topic, it seems that no one has refiled
the closed bug. If I can boot with an earlier kernel and the Flash
problem does not appear as noted there (I have not tested this
myself), is that enough to conclude that this bug should be filed
against the kernel?<br>
