Hi Mario,

I check the power consumption :
cat /proc/acpi/battery/BAT0/state | grep "present rate"
or 
cat /proc/acpi/battery/BAT1/state | grep "present rate"
Before resuming I need 14-15W (with wlan) and after resuming I need 23-24W and 
I hear the fan. (I can solve this with a simple 
command: /usr/X11R6/bin/xinit /bin/false -- :1)

If I start fgl_glxgears after resuming I see a black window from fgl_glxgears, 
but I can't do anything except moving the mouse pointer for some seconds and 
then it freezes too. No log entries or errors in dmesg or /var/log/Xfree*

I don't want to resume from console. It's also not important for me. 


The differences between our systems are that I use Xfree 4.3.0 and you are 
using Xorg ?.?. This can be the reason and I would be happy if a simple 
upgrade can solve this issue. (I installed Xfree because there exists no 
official packages for debian sarge in the moment)

Please write my a mail, that you have no problems with too much power 
consumption. fgl_glxgears is working always at your laptop with no problem ?
Do you use any frame buffer in console mode ?
