Hello,
I have just launch a diagnose software provided by Dell:
the video memory seems corrupted (error in writting or reading).
two days ago I plugged my daily updated Etch laptop to an external
screen
(in practice a projector) and everything went fine until the shutdown.
But since then my screen is `crazy': at start up, I funny caracter
appear
everywhere; in console mode the size of the caractere are no more
apropriate;
in console mode, vertical and horizontal line appear and disappear
in different
colours; in gnome session the same happens.
I guess that something was modified and need to be reset,
but I do not know what to do ? May be my screen is dying ?

Do you have access to a live cd like knoppix or ubuntu live? If so,
boot into it and that will test your screen. If it works, then what you
need to do is reconfigure your xserver/xorg config. One way you can do
this is to copy the live cd /etc/X11/xorg.conf into
hda/etc/X11/xserverconfig (I forget the exact name for xserver) or
hda/etc/X11/xorg.conf then reboot.
I find it doubtful that just running an external screen damaged your
video card. Most likely your xorg/xserver config file changed or your
fn-F8 is in the wrong position. It is possible your card is damaged
though. This test will prove that, one way or another.
It doesn't have to be a live CD, any debian install media will work,
just don't install :~)
