Comment 40 for bug 748137

apologies,
                 I keep getting my .gconf corrupted which prevents unity from loading. You are correct ... I deleted my profiles .gconf folder and logged back in and Unity is now loading as it used to do using the Radeon driver.

I still get graphics corruption (not the fkgrx black window issue posted here) which is the Radeon bug with my specific chip-set.
I belive this bug is associated with the shared graphics memory on my netbook. To avoid this I have to boot with radeon.modeset=0, which disables unity anyway!

You should not have my driver bug so you should work with the basic radeon driver and your hardware.... enjoy :-)
