Re: powerbook wakeup/boot display issue

Hi there,

Thanks Johannes and Michel for your replies. I haven't tried switching VTs yet, I'll try when the problem recurrs.

FYI. it was this forum that got me worried, its about half way down the page:


What do you think?

BTW I forgot to mention, it sometimes happens on boot as well (maybe 1 in 10?). Once it happened just before the penguin appears at the top of the screen, but usually just before the debian login window.

Thanks again,

The powerbook sleeps fine I think, but probably about 50% of the time, on wake-up, the display freezes with a black screen and then slowly begins to "bleach" white and purple from the top. Obviously I shut down immediately as this looks dangerous.

I've been told that this is completely harmless as it's just what
happens when the LCD is off but the backlight still turned on for some
reason, which causes the screen to go completely white after all the
crystals clear out.

I don't really have a fix for it. What happens if you switch VTs a few
times when it happens?
