thanks, you made me look at my BIOS and (at least I think) I found the
cause. There's an option called "Video Off method", which was set to
"DPMS support". I just switched it to "blank screen" and didn't
experience the usual problems after rebooting. I think (hope ;) ) this
solved the problem.
I'm replying to myself here. I wrote this on August, 5th, and I thought
the problem was gone. I was wrong! The problem was not gone and changing
the "video off method" configuration in the BIOS didn't help at all
(I've tried all settings related to this...).
Now, I can provide some more weird facts about this problem:
- I can successfully work around this problem by turning my PC on
_without_ turning on my monitor. Then, I login blindly and start Xorg
(XFCE4). If I turn on my monitor _after_ this procedure, I have no
"switching off" problems with my monitor. Curiously, this procedure
always works.
- If I turn on the monitor at some point _before_ starting Xorg, I
_always_ have this "switching on/off" problem with my monitor, until I
turn the monitor off (and wait a few seconds) and, then, turn it on
again. After this procedure, the problem is also gone. Furthermore, this
problem does only occur after turning my PC on for the first time (most
of the time, it works after rebooting if I don't wait too long before
starting Xorg...).
- the graphics card doesn't seem to be the cause (I've tried a Radeon
9600 and a Geforce 2).
- I don't have similar problems when I boot Windows XP, so I don't think
it's my hardware.
Now, this alone looks like a real problem, but there's more...
After upgrading CURRENT on August, 26th (I didn't upgrade since August,
5th), I have even more problems related to the console. After exiting
Xorg (I use XFCE4 as desktop environment), the console behaves totally
weird. Most of the time, I just see a black screen and no more console
output. Sometimes, there are just fields of black and grey (and blue
shades for kernel messages ;) ) on the monitor. Entering commands with
the keyboard still works, but there's no readable feedback on the screen
at all. I've also tested this with the Radeon 9600 and the Geforce 2 card.

Andreas
