what's your video card ?
and are you using dual monitors or one at a time ?

I am using one monitor at a time, My video card is ATI Radeon X800, Monitor is LG Flatron L1919S

Now I Use DUAL ones if that might help

See if you have a /etc/X11/xorg.conf file and if so try renaming it as a backup with

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

Now try a restart, or a logout and in again to restart x. You may find that a lack of xorg.conf will allow the system to re-detect all hardware and get you a GUI. If it makes no difference, you can reverse the whole proceedure with

sudo mv /etc/X11/xorg.conf.bak /etc/X11/xorg.conf

If that does not help, I will have to leave things to others who are better than I am.

Nope, Still the same. The worst thing is while I keep running both monitors everything works fine, when I plug out 2nd one main one again shows out of range.
also reversed procedure doesnt work.

while they are both plugged in go to system > prefernce > monitors and choose a monitor and turn off one monitor from there don't unplug it see what happens ?

[Bukarts]

How I can choose them, All I have available is to check Cloned monitors or not. And in window I see Cloned or unknown. So Now I managed to turn off first one and Leave Main one running. But I am afraid to restart now, since most probably I will get the same place where I was before.

Ok! Restarting now !

Yup Still the same! Out of range once again
