Comment 3 for bug 833549

It seems a compiz problem that only the desktop width is updated in compiz, but the desktop height is not updated after rotate.

Following steps can simplify the problem.
- boot the system in text mode
- run X in remote terminal
- disable unity plugin in ccsm
- start compiz in remote terminal
- run xterm in remote terminal, and maximize xterm
- run xrandr --output xxx --rotate left in remote terminal, we can see that the screen is rotated, and the right part of the screen is totally black (with width of <original screen width - original screen height>)
