["Mr. Norel" <sh1v4_0h@xxxxxxxxx>]

affects me in lucid

on a X1400 radeon (Toshiba a100 series),

adding radeon.modeset=0 as a kernel parameter is a workaround.

black screen (and some grey horizontal lines) occurs some time (1min+) after booting. 
happened 
-after loggin in (gdm) while loading my desktop (gnome) 
-but as well when plymouth asks me for the password

It is possible to switch to a text-console (shift-alt-f3) blindly and
reboot with ctrl-alt-del

this has been a problem for some weeks now:
I use radeon.modeset=0 now for some weeks. I waited with this bug-report because there has been some problem with gdm crashig always the first time I enter the login-password. This problem seems to be fixed with the plymouth update today. -> I tried again with KMS enabled(looks much prettier). still no luck (=black screen with grey lines).
