Unrecoverable Black Screen

[Osiris]

When I leave the computer for about 5 minutes to say... go to the bathroom, it goes to an un-recoverable black screen. could somebody help me with this problem?

Osiris,

I think I might be able to assist on this one...

First thing, are you running Knoppix from the CD?

If yes, I think it is "Power Management" that is causing this issue. To disable Automatic Power Management, the next time you boot Knoppix...

When you get the Boot: prompt, type the following to disable APM in Knoppix, for that boot

boot: knoppix noapm [enter]

Don't type enter, just press it, and don't type "boot:" thats the boot prompt.

If this works for you, you will need to enter the above command when you boot knoppix again, each time - Knoppix doesn't "carry over" previous configurations between boots, unless you set up a persistant home, or save knoppix configs from within the KMenu -> Knoppix menu entry.

Hope this helps,
Cuddles

Unfortunately, no. I installed it to hard disk, but I'm gonna check that out anyways, just in case. I appreciate the attempt though.

See if apmd is runnning:

ps aux|grep apm

If so try killing apmd.

kill pid (pid of apmd)

or

killall -9 apmd

You can also disable dpms (energy star features)

xset -dpms
