Dell Monitor Issue

I recently bought a Dell D600 laptop. I partitioned the internal hard drive and I am dual booting to XP Pro/Red Hat 9.

I am currently having an issue with RH9 when I close my laptop's cover. If I'm running XP and I close the cover the screen turns off and when I open the cover the screen comes back on - simple enough. In RH9 the screen shuts off, but when I re-open the case the screen is mostly black with a couple of colored lines at the top of the screen. I messed around with my display options, trying different dell laptop screens and different generic ones but I always have this issue. Any advice?

Could be a couple of things...

On my Toshiba Satellite, there's simply a little button that gets pressed in when the top is closed -- it just disconnects power from the monitor. I can press it with my finger and the monitor turns on and off.

On some laptops, the button is a bios trigger which windows picks up as a queue to suspend. It comes right back up when you open it up again.

On my toshiba, if I issue the apm -s command to suspend the machine, then hit the power button to bring it back up, I see something very similar to what you describe.

Could be that linux is trying to suspend when you shut the lid, and not successfully recovering from the suspend ?

Try removing the acpi or apm module and closing/opening the lid. That'll at least help narrow down what exactly the problem is.

Another thing that I have seen, regardless whether it's a laptop or desktop, is video cards and drivers getting confused about power management settings, and having to be rebooted for the original video configuration to come back. A power saving signal (maybe triggered by closing the lid?) could be confusing your hardware/drivers in such a way.

To try this out, try these commands from an xterm.

xset +dpms
xset dpms force off
xset dpms force standby
xset dpms force suspend
Touch a key to bring the monitor back up.
If you get the same result, then it's an issue with the x server and dpms, or "energy star" compatability.

Hope some of this helps

For a lot of reasons (different than this issue), I changed distro. I tried Mandrake with my laptop and got stability issues (a lot). The I installed SuSE and it works great. I dont hany any bugs so far. After 3 days using it, I think it is a great workstation distro. I fixed a couple of bugs I had with Red hat and a lot more I had with Mandrake.
