sudo lshw -C display; lsb_release -a; uname -a

Thanks

Yes sure, here we go

Install the proprietary video driver, it'll help. In Quantal if your video config isn't up to the challenge then it shifts rendering to the CPU.

I'm trying to install it (Video driver for the AMD graphics accelerators from fglrx updates (proprietary) but it is taking a while and it doesn't seem to be installing
I'll let you know when it finish installation

Thanks

Video driver for the AMD graphics accelerators from fglrx (proprietary) doesn't get installed

Under additional drivers I just see applying changes and the bar is just at the beginning and doesn't move, it has been like that for 5 minutes and I have tried a couple of times

Then try:

sudo apt-get install fglrx fglrx-amdcccle

Reboot to test

It is installed now from ubuntu CD and I restarted but when I log in I can do anything
I don't have tool bar or system control
Still I have the noise
How can I go back to other driver so that I can use ubuntu again

I installed Video driver for the AMD graphics accelerators from fglrx and my resolution was not good and I couldn't access side bar or system settings drop down menu
I right click on desktop and I went to system settings and I installed Video driver for the AMD graphics accelerators from fglrx (proprietary)

Restarted and I had the same problem, resolution and noise. After installing these two drivers I don't the green button under additional drivers

I went back to initial driver
advance micro devices (AMD) nee ATI: Juniper (Radeon HD5700 Series)
Using X.Org X server - AMD/ATI display driver wrapper from server xserver-xorg-video

CXan we try anything else?

Wondering if you got anywhere with this problem, as I am having the exact same. Tried both the proprietary drivers, and in unity the side and top bars disappear as well as borders around all programs. KDE loads but with extreme sluggishness in all window movement and other GUI actions. Furthermore, the propietary drivers did not reduce the fan noise at all.

Here is the output from my sudo lshw -C display; lsb_release -a; uname -a:

If you are using 12.04 LTS, you could possibly use Unity-2d instead. This though, was removed in 12.10 +. You could try something lighter like LXDE or XFCE.
