Re: lid switch on dell latitude d800 freezes system

[Markus Gutschke <markus-nyufa/AnP+9Wk0Htik3J/w@public.gmane.org>]

As mentioned before, I do not see any of these problems. Screen blanking 
works just fine when I close the lid. I get the ACPI event and then call 
xset to (un)blank the screen from a script.

I'd be happy to make my kernel (somewhat patched version of Linux 
2.4.21-rc1-ac3 with ACPI patches) and X binaries (Debian unstable, XFree 
  4.2.1.1) available to anybody who wants to investigate this problem 
further.
