I have a Dell Inspiron 14z ultrabook and using the radeon controller when I switch from console (control + alt + f5 for example) to X (control + alt + f7) my X session is crashing.

When it's happening i always have to connect to my box using SSH and restart the X session. During some researchs i found it:


It's exactly what's happening here but unfortunatelly was not replied. :/

Using fglrx it's not happening but i just not want to use that proprietary software in my operating system.

Someone here can help me?
