I installed the ppa and tried with kernel mode setting.
But my system became very sluggish, i mean really very very sluggish.

Even so, i tried cairo-dock but it *would not start* .
I ran cairo-dock in debug mode and it had only one line:

drmRadeonCmdBuffer: -22

I'm still running the ppa but without KMS , if i run cairo-dock using openGL it has the same artifacts as before.[i understand this problem would only improve with KMS but just mentioning].

So now ,
1 . does the above error i got for cairo-dock with KMS , have to be dealt with by cairo-dock or by the graphics driver?

2. Could i have a link to the bug for the radeon KMS slow behavior, i wouldnt mind testing any unstable drivers which fix this.

Thanx for the help :)
