[SOLVED] Display problem in Ubuntu in ATi

[Canis familiaris]

I solved the flickering problem by following this useful post.

If you want to fix the flickering widowed video problem you can edit the appropriate sections of your xorg.conf to look like this:

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "aticonfig-Screen[0]" 0 0
Option "AIGLX" "on"
EndSection

Section "Device"
Identifier "aticonfig-Device[0]"
Driver "fglrx"
Option "XAANoOffscreenPixmaps" "on"
Option "TexturedVideo" "off"
Option "VideoOverlay" "off"
Option "OpenGLOverlay" "off"
Option "Textured2D" "on"
Option "UseFastTLS" "1"
Option "BackingStore" "on"
EndSection

Section "Module"
Load "glx"
EndSection

Section "DRI"
Group "Video"
Mode 0666
EndSection

Section "Extensions"
Option "RENDER" "Enable"
Option "DAMAGE" "Enable"
Option "Composite" "Enable"
EndSection

Then run, in a terminal:

sudo aticonfig --input=/etc/X11/xorg.conf

to write the changes to the actual ATI config file.

This will only work with the ATI driver 8.4 and newer. Also, you must have redirectfullscreenwindows checked in the compiz settings manager.

The TexturedVideo "off" option can cause some full screen playback problems for older cards and slower cpus but will get rid of the windowed playback flickering. You can turn it back on for full screen high def playback if you need to.

ATI has recently made a great change in their commitment to linux, releasing source code to the driver writers groups, etc. They also seem to be committed to proprietary driver updates for newer cards about every six weeks which includes 3 weeks of testing before release.

They are aware of this problem with compiz and OpenGL and are working towards a solution. The 8.5 and 8.6 drivers have a lot of improvements over the 8.4 in the repos. The screensaver problem is fixed. The Compiz problem will be fixed soon.

I expect that by the fall, ATI will be at least comparable to Nvidia.

I hope in the future just setting drivers of ATi and compiz would not be so difficult in the future.

i have the same ATi IGP card.
When I try "sudo aticonfig --initial --input=/etc/X11/xorg.conf --resolution=0,1024x768"
I get:
Found fglrx primary device section
Nothing to do, terminating.
error at set screen resolution : screen0 does not exist
aticonfig: parsing the command-line failed.

When I use:
sudo dpkg-reconfigure -phigh linux-restricted-modules-`uname -r`
I get:
Package `linux-restricted-modules-2.6.24-18-generic' is not installed and no info is available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
/usr/sbin/dpkg-reconfigure: linux-restricted-modules-2.6.24-18-generic is not installed

I'm a complete newbie. Plss help

Did you try installing the restricted kernel modules.

sudo apt-get install linux-restricted-modules-`uname -r`

Also the ` is not ' ` before uname -r is the key left of key 1 and over Tab.

I noticed after I installed the new driver that a few minutes later Update Manager informed me that it had a few updates for me and it turned put that they were the updates to the restricted modules. This was with the -18 kernel.

When I updated to the 8.6 driver while on the -19 kernel I waited a few minutes after the install and sure enough, Update Manager had restricted module updates for me. So now, after installing a new driver, I give Update Manager a few minutes.
