I'm new to Linux/Ubuntu and experiencing the following problem:
I start my computer, and get to the GUI where I can login. When I click Ctrl+Alt+F1 I will get to the first of the consoles, everything is fine so far. But now I can't switch back to the GUI. When I press Ctrl+Alt+F7 or only Alt+F7 (I have tried both), the screen goes completely black and there is nothing I can do. Ctrl+Alt+F1 or Alt+F1 will NOT bring me back to the console, neither does any other Ctrl+Alt+F# or Alt+F# combination.
Sometimes (and I'm not sure what it depends on whether it works or not) I can switch back to the GUI once. But if I then go to the console again and try to go back to the GUI a third time, it never works.
I am using Ubuntu 12.04 LTS 32-bit on a very old (7 years) Fujitsu Siemens Laptop (Intel Pentium(R) M Processor 2.00 GHz; 1GB Memory). Could it be a hardware problem? Thanks a lot in advance for any help!
fnkey to the combo, since it's a laptop you probably have a different "key behaviour". something like CTRL+ALT+fn+F7 or similar.
