Installing fglrx fixed my problem too, limits Visual Effect to 'None' by
doing so, but who cares. Thanks for the work-around Carl! Don't know
this post helps with the bug, except maybe that it confirms that the bug
is with (or some how related to) the default Radeon driver.

Radeon gamma
** Description changed:
Binary package hint: xserver-xorg-video-ati
Ubuntu Lucid Lynx radeon driver has a bug, which causes
gamma/contrast/brightness settings to be messed up.
http://ubuntuforums.org/showthread.php?t=1438810
Display is okay with Karmic Koala kernel 2.6.31-20.
Problems disappear when using fglrx, but then you lose compiz (and free-
ness!)

Same problem here on HD3650. Just to mention that it's not a cosmetic
issue, Xorg display is really unusable, black text on white background
is unreadable, text on button too, so you can't use the computer...

Radeon gamma bug, display too bright when using VGA
I think I'm seeing this same problem on a Radeon HD3450. I have two
identical monitors, both with VGA inputs. One is connected to the
card's VGA output, and looks fine. The other is connected to the card's
DVI output via an adapter, and looks washed out in the sense described
by other
No, it does not qualify as serious in comparison with other X bugs.
It sounds like more than a cosmetic issue, though, so setting to medium.

I've found something.
My display has DVI and VGA inputs. I am using DVI-VGA adapter for
ANALOG input for my monitor. The ANALOG input is too bright, like
described above.
If switch to DVI, then colors/brightness/gamma are fine.
So the problem is with ANALOG output from VGA.
I tried with
Me too.
I agree that this issue should be considered serious. It 100% affects
the usability of Ubuntu. I can (barely) cope with the issue for a short
time, but it * IS * a deal-breaker if its not fixed in the Beta. I was
also using 10.04 Alpha (1 or 2, don't recall), and I was NOT having this
I have attached a photo of 2 monitors, from 2 separate computers with
the same HTML color chart, side-by-side. On the left is a Windows
computer, and the right is the Ubuntu 10.04 Beta1 computer that is
afflicted with this bug.

I have the same problem. The screen has just got really bright for no
reason, and there seems to be no way to control it using software. It
started happening after I updated recently. I'm using a Radeon HD 4350
on an AMD64 installation

I've tried adjusting my monitor settings but it doesn't change anything.
This is probably something to do with the software

Radeon gamma bug, display too bright
I am the one who started the original post. To clarify the bug, I have added
camera photos using identical manual settings of the screens from Lucid
(radeon) and karmic (flgrx). Note that all images are of the same bootchart
file. The images are as follows:
