I moved to lxde
I installed linux into this computer around 3 months ago. and I am loving it. as long as debian in my pc I am happy :) the other day I disabled fn key from BIOS and suspend started working also. I am not sure which one solved the problem. turning to lxde or that bios thing but still I am happy about this.
because closing the lid and opening it and not finding X was frustrating. and I had a lot of restarts because of that. now it is working like it suppose to.
