If you're changed kernels since you last rebuilt xorg-server (shown in the
top of the Xorg.0.log file) then there's a very small chance rebuilding it
will help. Otherwise just mask the new packages and downgrade.

[gentoo-user] Radeon driver not happy

[Mick]

Since the last radeon/xorg/mesa update things have been rather ropey on two 
different boxen, both of which run stable arch with enlightenment as a 
desktop.  On one of them (ATI Mobility Radeon HD 4670) it has been impossible 
to work in LibreOffice without a complete lock up of the desktop.  On the 
second more modern system running a Kaveri APU things are more stable, but 
crashes will occur there too eventually.

From what I have noticed the desktop appears to freeze completely when I 
happen to hover over a region in an application window, which generates a 
tooltip popup.  The popup boundary shows up faintly, its content does not and 
the desktop is by then completely frozen.  Ctrl+Alt+End which should restart 
the composer, does not.  Ctrl+Alt+Backspace kills the X session leaving a 
number of defunct elements behind, like gkrellm.

This is what Xorg.0.log shows:

Any idea how I can overcome this problem.  I makes any work on the desktop a 
precarious activity, but especially so on LO which is guaranteed to crash.
