Dear Srs,

I've got a new plain install of etch which is running ok, with
Xorg/kdm/kde.

The modes are ok: I have only four resolutions (1280x1024, 1024x768,
800x600 and 640x480) and I can see all of them right after a boot, by
cycling the modes with ctrl-alt-plus and ctrl-alt-minus.

However, if Xorg is restarted for any reason (ctrl-alt-backspace,
logoff, telinit 1 followed by ctrl-D, /etc/init.d/kdm stop followed
by /etc/init.d/kdm start, etc.) it *does* run (no errors in the
console), shows in "#ps -eal <return>" output and I can even
(blindly) login successfully, but the screen remains black.

Also (this is interesting), the same happens if I switch to a console
and then back to X (ctrl-alt-F1 folowed by ctrl-alt-F7).

In every case, the system still reacts to ctrl-alt-plus,
ctrl-alt-minus and ctrl-alt-backspace (I can hear my TRC display
switching scan modes), but there is no image at all - well, there is
a very subtle, almost completely dark, glow in the screen, seeming to
be the correct desktop scan size, but nothing identifiable.

As far as I could test, the only way to restore proper operation is
reboot (sigh!).
Any hints?



What sort of video card do you have? If it is nvidia or ati, for
example, you could try switching between the free and non-free drivers.
