Is it possible to rotate the GNOME desktop through 90 degress (portrait mode)?
It is, and depending on the video card and driver you are using, should be relatively simple.
Open the "System" main menu, then go to Preferences --> Hardware --> Screen Resolution. From there you can choose the Rotation of your choice.
I don't know for sure which video card/driver combinations support it and which do not; but my testing is successful with my own workstation (G965 video using the current xorg-x11-drv-intel stack).
Alternatively, you can use the 'xrandr' tool from the command-line if you prefer that method. Check it's documentation for more details (`xrandr --help` or `man xrandr` from the terminal).
Hope that helps.
