12.04 freezes after upgrade, disabled all nVidia drivers, reverted to kernel 2.6 etc.

Hi,

Freezing up requiring reboot post 12.04 upgrade, lost my launcher and top taskbar, pages acting weird/wont move or minimise but I did manage to restore them briefly by disabling nVidea drivers which I hear can cause problems..?

Im running HP Pavilion tx1000, memory 937.0 MiB, Processor AMD Turion 64x2 Mobile Tech TL-56x2, OS 32 bit

Graphics appears to be Gallium 0.4 on NV4E after the upgrade and disabling all the nVidea drivers.

I have done the left shift thing on startup and booted the old kernal, problem persists.

Im real new to this Ubuntu world...not too fast....

Cheers Dean
