Comment 22 for bug 528720

My PC with a Nvidia card works perfectly and is not affected by this bug and my PC without Nvidia card (without any graphics card at all ) is badly affected by this bug to the extent that Ubuntu 10.04 is unusable (some of the programs I would like to run like blender3D freeze as soon as I move the mouse cursor in 3D space).
This problem also affected this PC in Ubuntu 9.10 (when I noticed it for the first time).
I would have to agree with Kron K's comments that this might be a graphics issue. I'm not convinced that this bug is totally a keyboard and mouse issue. Although the PC affected doesn't have graphics card installed it does seem to have a built-in intel type graphics chip with a minimal amount of memory to speed to 3D graphics minimally.
Also the program most badly affected by freezing uses 3D graphics extensively.
When I first installed Ubuntu 10.04 it froze almost immediately on start-up every time but after selecting to boot in safe graphics mode the problem essentially seemed to disappear but I still can't run Blender3D in Ubuntu 10.04 because it still freezes every time.
