Dear F18 users,

having an old Fujitsu Siemens Amilo notebook with ATI graphics:

01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee
ATI RV350 [Mobility Radeon 9600 M10]

Sometimes, if switching between GNOME3 desktop and some TTY
(ctrl+alt+Fn,n>1), the box hangs up: The screen flickers all 3 sec's,
and no more input is possible.

X11 problem?

Seeing in /var/log/messages a lot of lines like:
