Gnome 3 display problem

[piyush|]

When I switch from Ubuntu's default GUI to Gnome 3, the desktop looks gibberish.The color scheme is messed up , the taskbar is not understandable.

Tell me the ways to solve this problem.

A little more background please:

Were you using Ubuntu or Ubuntu 2D?
Are you using an ATI graphics card?
Upgrade or clean install?
Same problem using Gnome Classic or Gnome Classic (no effects)?

I was using Ubuntu
ATI HD 4250 (onboard)
upgraded the 11.10 Beta to 11.10 official release

The problem arises only in Gnome desktop
Gnome classic,ubuntu ,ubuntu 2D are running fine

If its the graphic driver you might try this:

In /etc/modprobe.d/radeon-kms.conf, set
options radeon modeset=0

IF the file does not exist create it.

Does this assume that the user is using the proprietary ATI driver instead of the FLGRX driver in Ubuntu? My system does not have the file but it does have a file fglrx.conf and in that file the radeon options are turned off:

# This file was installed by fglrx
# Do not edit this file manually

blacklist radeon
alias fglrx fglrx
alias radeon off
alias lbm-radeon off

Yes, I was making that assumption. See https://bugs.launchpad.net/linux/+bug/556782

I battled the ATI problem over several Ubuntu releases with my Gateway Lt31 netbook. It was not until I installed Lubuntu that it really worked.

The link to the bug report you provided deals with issues in Gnome Classic (Gnome 2) not Gnome 3. Personally, I never had issues with my system when using Gnome 2 on my ATI graphic based system. It is only with Gnome 3 that issues arise. In addition, I tried installing the latest ATI driver (11.9) right after a fresh install of 11.10 and it completely breaks both Gnome and Unity so that the desktops are basically unusable.

so how do I solve this problem
I can see 2 drivers in driver menu to select

Both are of AMD but on of them is post release version
the post release version isn't downloading completely
it gives error in middle of the process

however the other AMD driver(non- post release version) was downloaded properly
