Title:
bad flickering with Radeon drivers in 12.04
This flicker is far worse on GCN hardware (Radeon HD 7xxx). The instant
you boot into Ubuntu with the open source radeon drivers, there is
massive amounts of black boxes flickering all over the screen. Even with
xorg-edgers/ppa like above, it does not solve the issue. The only driver

After installing the ppa:xorg-edgers/ppa the flicker seems to have been
fixed. This leads me to conclude that the issue was caused by something
done in the default Ubuntu install of X. However, it would be nice to
see some of the changes with the 1.12 server and drivers to be brought
into
This bug is still prominent in the Open Sourced drivers. I have found
many many references to people with this same issue and also with AMD
4200 series cards.

Just a me too here. Bad flickering in darkened areas after a return
from an idle screen shutoff with the radeon drivers on a MBP 8,2 and
Unity on 11.10. None of the above fixes worked for me

Daniel, thanks for pointing to 862430 since I was affected by the recently
duped 876198.
However for this one it might be worth extending my comment #2 where my
notebook (unity+wall) isn't affected by the flicker while it has the same
graphics card as the op [Mobility Radeon HD 4200 Series]
I am testing that option right now, I will report back once I give it
some time to test.

The EXAVSync option did not make any difference, nor did the Option
DisplayPriority BIOS or Option DisplayPriority HIGH options. I
did not see any noticeable difference between the two.
Right now the status on this ticket is incomplete; is there anything I
need to do on my part to get some

WoW!!!
Using step 2 from above and tweaking the radeon driver [Option
SwapbuffersWait on] in the xorg.conf file solved this problem
perfectly!
This issue has been bugging me for almost a full year since 11.10.
Now that we know that this is the problem and your fix works, is there

Another note. After completely removing the xorg.conf file, at first
startup the flicker dissapeared, and, again, came back after a couple of
minutes of use. Setting [Option SwapbuffersWait on] in the xorg.conf
file was ineffective, and there is no difference between with or without
the xorg.conf
I have seen the diagonal tearing on just about every ATI/AMD graphics
chip I've ever tried. Though I only remember seeing it with fglrx, not
radeon. That strange diagonal tearing is certainly something you'll only
see with ATI/AMD graphics. It seems to be something to do with the ATI
hardware or

I did try enabling Force full screen redraw (buffer swap) on repaint
in ccsm did not aleviate any flickering and only caused more artifacts
and screen glitching than before.
Also, it isn't by any means exactly 5 min, and I believe that it is more
based on usage. Sometimes the tearing will happen
Also, like I stated way before in the thread, when I was running Arch
Linux there was no flicker using open sourced drivers. I am wondering if
we can backport a fix that they used. I do not know enough about this to
be of much use though

Britt, if Force full screen redraw (buffer swap) on repaint doesn't
work then that confirms there is a problem with the driver. or hardware
(probably driver). Because that option should give you flawless silky-
smooth graphics so long as vsync or SwapBuffersWait support is enabled
in the driver.
Option EXAVSync on
also sounds promising...

Britt -
1. Please provide a video of the flicker if possible.
2. Please also try tweaking some radeon driver options in /etc/X11/xorg.conf:
Section Device
Identifier devname
Driver radeon
Option SwapbuffersWait on
EndSection
3. Try a workaround: In ccsm,
Wait, I take it back. It worked beautifully initially on startup, but
after about 5 min of use the flicker has come back. Why would it work
right at startup, but begin to flicker after a few min of use?

Just an update, but with the last few xorg updates that have appeared in
the past few days, this issue is still apparent.

I would also like to note that my laptop with my Mobility Radeon 4200
series is the one that has the flickering, my desktop with a Radeon HD
6950 does not have any flickering.

Britt, a few questions.
First, is this a regression? If so, when did you first start noticing
the flickering?
You mentioned there was a recent fix released; can you supply some
additional pointers as to what that fix was or when it went in?
You mentioned you don't see it in Arch linux; what
This is not necessarilly a regression, as I have yet to know an
experience in Ubuntu with the open sourced Radeon drivers without a fair
amount of flicker. (There has been flicker since 10.10 when I first
started using AMD graphics on my laptop and desktop). The bug that was
filed said fixed
