Screensaver dies?

[Josef Wolf]

Hello,

I have installed ubuntu-9.10 on this acer travelmate 8371 in december last
year. I have configured the screensaver (black screen) to get activated when
the laptop display is closed.

For the last four months, I had no problems with this setup.

Today, in the morning, the trouble appeared the first time.

I opened the display and had a black screen (the screensaver). But hitting
various keys did not help, the screen remained black. The keypad seemed to
be dead and switching to virtual console via ALT-F1 did not work. I could
login via ssh, but could not see anything unusual. So I killed the
screensaver. But this did not help at all.

Then I rebooted, and anything appeared to work as usual.

Then I closed the display again and moved the laptop around (removed the
power supply, maybe this has to do with the problem?). Now I open it, and
again, the screen remains black.

In this situation, the laptop is totally unusable to me at all.

Any hints?
