Dear all,

I have a Hp 6710b laptop, where I am using an external monitor with the extending options that xrandr provide. The problem is that my laptop screen routinely goes dimmer and comes back after a certain time, it seemed to me some kind of power management issue but could not find the reason. Any ideas?

One more thing is that when I use the dual monitor(extended screen) I should set up the resolution at each login. I could not understand why this happens, should I read xrandr 1.3 manual more?

When using 9.04 and xrandr 1.2, it was set up correctly but with 9.10 apparently, I experience some problems

Any pointers are appreciated.
