I find this is annoying. When the opensuse 10.3 system is left untouched for a while, the screen will be locked. To unlock the screen I need to
shake the mouse a little and the screen that prompts for passwd will usually appear.
This is good. It means I can unlock the screen with my passwd. However, sometimes the unlock screen does not appear at all (or the screen may go totally blank). In this case, I have
to do a control-alt-BackSpace to restart the X-server. Is this problem
particular to opensuse 10.3 (32-bit) or the my computer model. My model is Fujitsu A6030 with
a 16/10 ratio, Mobile Intel GM 965 Chipset.

I have the same problem with the 64-bit opensuse, but it seems 32-bit
opensuse has a higher frequency (okay, I just switched to 32-bit recently so i have to see if this is true in the future).

My problem may not be due to power management, since pressing the power
momentarily once does not wake up the system.

I have never the problem you mention although I use suse 10.3 64 bits version for more then a year now
I just pressed enter when I like unlock the screen it always works
What do you mean by pressing the power momentarily
As you surely knows the power safe startup at boot time
But changing the kpowersafe might help to reduce you,re problems and may by the power safe in you,re BIOS too

all the best

I meant pressing the power switch once and let go the finger immediately. Usually this will bring the computer back if it is sleeping. If I press the power switch too long, then
the computer will be powered off, an operation which I have to do if the system refused to wake up..

Since I am at this topic, I have changed the default properties and see
if I still hit the same problem.
