First try s/r without X running and see if it works ok.  Then try s/r
from a VT other than the one X is on. Finally, try s/r with the DRI
disabled (i.e., Option "DRI" "False" in the device section of your
config).  Also for non-kms s/r, you may have to fiddle with vbetool on
resume to post your card.  Report back with the results and we can go
from there.
