This included both libreoffice (the default) and openoffice (from the

gimp, on and on, and would surely have taken a week or so under Gentoo.
Today, I port over my apache configuration and my embarrassing downtime is

I wonder which kernel version you use, because in 2.6.36/37 I was hit by a =
nasty<br>
EDID parsing bug. Actually, IIRC the code for parsing EDIDs was updated to<=
br>
understand more features or something, and that triggered errors that didn&=
#39;t<br>
come up before because those parts of the response from the monitor were si=
mply<br>
ignored until then (or something like that). This lead to my own monitor no=
t<br>
responding for over a minute at a time (sometimes going blank in between) a=
nd<br>
other people complained that it left theirs permanently blank.<br>
<br>
I think this is the original bug:<br>
