I have not checked recently Daniel.  The last time I did check, it was ok, 
but radeon was refreshing the screen really slowly, making it difficult to 
scroll in FF and similar apps.  I believe the ati module makes that choice, 
but let me check the log, brb.

Hmmm, brb was a rather optimistic statement.  Switching /etc/X11/xorg.conf to 
define the radeon driver instead of the radeonhd results in an x server crash 
and no video from either output on the card, and is not recoverable with a 
ctl-alt-bsp.  ctl-alt-del gets me a boatload of dirty inodes cleaned up 
messages on the reboot too.   And once I had to use the hdwe reset to reboot 
it, I tried it several times with the same no signal to the monitor results, 
I'd guess at less than 500 milliseconds after I hit the return on  a startx.

So I am back on the radeonhd driver and things are hopefully back to as 
normal as they usually are.

Is this helpful?

Thanks for the prod.

Cheers, Gene
