Ubuntu Hardy 8.04 beta w/updates. Toshiba M35X-S114 with 855GME integrated video.
If I use the Fn+F5 display switch without an external monitor connected the system usually freezes. No log messages, no magic SysReq, no remote ssh, no LED toggling - just a black screen with a frozen mouse cursor. It doesn't matter if the monitor was connected when X was started. Even with it connected the switch doesn't seem to have any effect on display switching as the view is cloned regardless (which matches BIOS setting). There is only a small display flicker when the switch is actuated to indicated that anything happened (unless it freezes). Freeze does not occur with the i810 or vesa drivers or from within a VT with the intel driver. The i810 driver correctly cycles between the built-in, external, and both. Occurs with previous versions of the intel driver also (Bryce Harrington builds):
xserver-xorg-video-intel_2.1.0+git20070625.ccac60bf-1_i386.deb
xserver-xorg-video-intel_2.2.0+git20080102.0fd769b5-1_i386.deb
Also occurs with Fedora 9 beta on a Panasonic CF-51 with the same chipset. It has a serial port but there isn't any messages on the serial console either when it occurs.
