"Dad, there’s something wrong with the computer!"
If you ever pressed Ctrl-Alt-Right it could happen that your screen got rotated.
The Ctrl-Alt-Direction key sequence is supposed to be used for changing your workspace.
On my computer at work it changes the screen orientation.
Ctrl-Alt-Up - right side up
Ctrl-Alt-Right - 90 degrees
Ctrl-Alt-Down - 180 degrees
Ctrl-Alt-Left - 270 degrees(If that doesn’t work, try Ctrl-Shift-R)
Looks like ATI & Intel copied the keystroke for the same “feature” in their video card drivers.
To fix the issue press Ctrl-Alt-Up. To permanently fix the problem go to:
Start >> Control Panel >> Display >> Settings >> Advanced
Where it is after that it dependent upon your video card. Look for hot key section.
