Go to System --> Preferences --> Display

and try different options for 'Refresh Rate'. Does this solve your problem?

the flickering as not stopped do youhave any other ideas?

it resolved my problem for now if i have anymore problems i will post

I am still having the same problem and it will not go away i have the refresh rate to 60 hz and it is still doing it anyy ideas?

The Intel graphics driver code is going through some major development and there are a number of known problems. You may wish to read the following page and consider rolling back to an older driver.

https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4

the link you sent me worked great however i do not understand how to go back to an older driver.

Please provide more information also please provide screen shots on how it is to be done thank you.

Go to a terminal and type:

gksudo gedit /etc/apt/sources.list

and add the following lines to the file:

deb http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main

Save it, and close the window. Next type:

sudo apt-get update
sudo apt-get install xserver-xorg-video-intel-2.4

You may get a warning, but you should ignore that.

Oh, and restart Ubuntu.

when i type that command in a terminal i get the following message:

bash: gk command not found

"sudo gedit /etc/apt/sources.list" also works like "gksudo gedit /etc/apt/sources.list"

how do i know if the update and installation helped?

> bash: gk command not found
you probably typed it wrong. It's gksudo, not gk sudo. ;)

I think i have it working and i restarted ubuntu how will i know if it worked ?

i finally found out how to edit the file

i am getting furasted with this the display is still flickering i did the install and the upgrade what else is there for me to try?

I can add to this by saying I have the same issue. I have found that mine appears to be related to network activity. If I am disconnected from my wireless network, or not browsing the web/using Pidgin/etc, I don't see the flicker, but my screen will begin flickering as soon as I have alot of network activity.

I tried to use the proprietary madwifi driver, but I was unable to connect to my wireless with this driver. Could this be related to the issue being discussed?

i have to say i can just let the screen sit here and not be doing anything and i see the flicker any ideas?

by the way i am using the following Graphics card:

intel mobile 945 Gm

ubuntu at the install installed the driver

this is a annonying!!!

please reply on how to fix!!!

Just a trivial question, did you try to turn off compiz and run the default window manager metacity?

i uninstalled compiz but how do i rrunthe default window manager metacity?

It automatically falls back to using metacity by default when compiz is removed.

metacity --replace

You may also check if compositing for metacity is disabled, open gconf-editor, navigate to
/apps/metacity/general - compositing_manager

Are there any errors in Xorg.0.log (system administration -> system log)
grep -i error /var/log/Xorg.0.log

Reference:
http://library.gnome.org/users/gconf-editor/2.22/getting-started.html.en
https://wiki.ubuntu.com/X/Troubleshooting/
https://help.ubuntu.com/community/LinuxLogFiles

do i have to type this in a terminal and what is the command for doing this?

when i type in the command window and i type gconf-editor the window opens and then i open
/apps in the apps column i do not see /metacity/general-compositing_manager

am i doing something wrong???

Matthew,
metacity --replace
is a command to type in the terminal, the output will probably tell you that it's already running.
The process of metacity can be viewed also in system administration -> system monitor

Please type this in a terminal and post the output here:
gconftool --get /apps/metacity/general/compositing_manager

I am not at home right now I am at work and when i get home i will try it and post here if i have any issues

 here is what the log says my graphics driver

No Layout section. Using the first Screen section.
(**) |-->Screen "Default Screen" (0)
(**) | |-->Monitor "Configured Monitor"
(**) | |-->Device "Configured Video Device"

does this configuration sound right???

how do i see what kind of driver i am using
?

(II) LoadModule: "radeonhd"

.. indicates I'm using the radeonhd driver. Why don't you just roll back to Intrepid?

so you are saying that this can be fixed can you provide me with a screen shot as an example of what command to type in
