Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
The Fn+Home event crashes X even with the normal non-xen kernel. Ubuntu says it's caused by the broken video kernel module and blacklisting it solves the problem: http://ubuntuforums.org/showthread.php?t=320750 It's needed to say that that removing the video module (at least on FC6) causes the acpi events from the Fn+Home keys not to be processed at all, what is not really a fix. It gives some clue though. It crashes regardless the X is in the VESA mode or with the fglrx binary drivers installed.
Are we talking about this https://bugs.freedesktop.org/show_bug.cgi?id=2000 ? Does adding this option to /etc/X11/xorg.conf, the device section makes things work? Option "BIOSHotkeys" "on"
Adding this option to the "Device" section did not help. X still keeps crashing with Fn+Home, sorry. The bug on freedesktop doesn't seem to be related as the problem described there is reported for T42 and Fn+F7 (switch to the external monitor) and Fn+F7 doesn't crash X on my T60. Thanks for the effort.
A new BIOS released several weeks ago for T60/T60p, and after updating the BIOS, the problem changed. Before: Fn+Home = crash Now: Fn+End = crash Even with BiosHotKeys option. Moreover, the problem only exist with Xorg driver, if use fglrx, it is OK.
Could you please attach your xorg.conf here so that I see what is different in my setup? My T60 keeps crashing even with fglrx.
