I am not sure if i have posted it to right place, so if no please don't judge me, I am a newbie.

I installed Ubuntu 13.04 and I am happy with it. I have two OS's in dual boot. Ubuntu and Windows 7. in Ubuntu I have 2 problems. The first one is when I suspend my system I cannot resume it again. It sometimes show me the password screen (user names and etc. (sorry i don't know the exact name of it)) and sometimes just a blank screen. what can be the problem?

The second one is this:

enter image description here

When I hit ALT+F2 it looks like this ( but not always. when I restart the system everything is OK till about 30-40 minutes. and then it looks like this. Please help, I really like Ubuntu but these 2 problems ruin my plans about it. Thanks
