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.
