HI, Another observation I had with my X40 was that suddenly I was able to darken the screen much further than before by pressing the illumination intensity buttons. Actually the illumination of the screen seemed to have made a jump to very dark. While I thought that the screen had died again, I quickly pressed the #brighter# button, and one button press of the "brighterrr" button was sufficient to but it back to the lowest normal level which I was used to. That is not normal either, is it? Does it give a clue of what is happening? I have experienced that only once since the upgrade to suse 11.1. best, Volker Volker Krueger wrote:

Dear all,

thanks for the information so far.

As a matter of fact, I do not use compiz.

I have posted my email also on the suse forum. Let's see what they will say about this.

So far I couldn't imagine that a software bug could indeed distroy the screen like this...

best, Volker

A google search does turn up alot about this, for example compiz / general composite seems to blame sometimes, I just set it back on and could resume fine, don't know about the time it didn't work for me.

Don't get normal "screen doesn't come up on resume" bug reports mixed with "screen harware was destroyed on resume" ;-) The first class is annoying but expected. The later is *extremely* grave and has happened at least once in the past.

The system itself is not dead, not even the graphics driver it looks like, just the screen power or something. http://forums.fedoraforum.org/showthread.php?t=205270

Yeah, it looks like it does something Bad to the backlight PWM control, since it hits LEDs (inverter-less) and CCFL (inverter-based) boxes alike.

Looks like a very confusing issue =(

That it is, that it is...
