I've got snow on laptop display. It was there from the point when ati driver
got KMS support, and it is still here.
Noise appears only when KMS engaged, both in console and X.

Thanks for following up. This bug report is being closed due to your last
comment regarding this being fixed in latest Ubuntu.
If others are facing similar bugs, kindly file a new bug instead. Not all
driver issues are the same, the symptoms might be the same but need not be the
same underlying

Hi jMax,
This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?
Please note we also provide technical support for older versions of
Ubuntu, but not in the bug tracker. Instead, to raise the issue through
normal
Personally my laptop is now working perfectly since trying the final
release of Lucid. However it seems clear that some people are now
getting a similar sort of issue on Lucid. We've had at least 2 people
who seem to be able to reproduce it in Lucid so surely it would be
premature to mark it as
This morning I plugged an external monitor and I get the behaviour
described in the bug #537640.
One of the solution proposed for that bug is to execute the following
command in order to disable KMS:
echo options radeon modeset=0 /etc/modprobe.d/radeon-kms.conf
It worked for me and it seems
It seems to me that I have exactly the same problem. I have just updated
to ubtuntu 10.04.
I'm using a dell inspiron 6400 with an ati x1400 and open source driver.
As Seth Chandler I'm posting the output of xrandr --prop
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192

I'm getting the same problem Chris mentions above on live installs.
There is a static on screen (it feels to me like the refresh rate is off
by a fraction). I can't seem to set coherent mode on LVDS using xrandr.
Note that I'm also using a studio 15 with the HD 3400. Output of xrandr

I seem to be getting this in Lucid beta 1 64 bit version. (only tried on
live disk version so far)

The patch that fixes this according to the upstream bug, is already
present in Karmic. According to the git changelogs, this patch caused a
regression (subsequently fixed with other changes) so is probably too
high of risk for backporting to Jaunty. However once a new official

Hmm, I can't set coherent_mode on my card (see attachment).
The only information I can find on coherent mode is this:
http://bugs.freedesktop.org/show_bug.cgi?id=21050
Quote: Coherent [mode] ... affects how the clock is recovered in the monitor.
Most new monitors prefer coherent, however,
Reading https://bugs.freedesktop.org/show_bug.cgi?id=21553, I found the
problem is related to coherent mode (What's that ?!?). Command line
below solve the problem.
xrandr --output DVI-0 --set coherent_mode 0
I can enjoy again my 1600x1200 screen !
Does anybody knows how to make coherent mode
Seems to be this upstream bug:

I can confirm this exact same behaviour. White static on a 1920x1200
resolution, doesn't happen in 1680x1050, 1600x1200 or below. Doesn't
happen either on Intrepid + fglrx, or Windows XP. Since I also have the
flickering bug (sometimes, screen switches off for one second), I
tested if the CPU

Since update to Jaunty, I'm experiencing very strange bug when using high
