Public bug reported:

Binary package hint: xorg

When plugging in an external LCD Screen (LG Flatron L1915S) into my
Thinkpad R60 Laptop, it works only very inconsistently. What happens is
that the screen shows for a split-second and then goes dark.

This behaviour occurs sometimes when resuming from hibernation, or just
when hotplugging the screen. I even had it when booting up with the
screen connected. I am finding it difficult to pinpoint the exact
conditions of the error.

Further, when it does work, as soon as I plug in the external screen,
all desktop effects are disabled, and I have to enable them again. Also,
Desktop effects don't work when displaying on both screens.

The bug report command was run at a time where the external monitor was
working.
