Hi poma

that did it thanks 

/etc/modprobe.d/radeon-kms.conf:options radeon modeset=1

I mind you I still get the initial:
 [drm:radeon_init] *ERROR* No UMS support in radeon module!
And the plymouth splash screen goes from one mode to another and ain't what it 
used to be!) - but that doesn't matter. On loading, the kernel sorts things 
out.

A assume if I now reboot into the previous kernel, that wont work - I'll just 
do it out of curiosity - but no probs - I'll now stick with 
3.17.8-200.fc20.x86_64.

Thanks 
Andy
