How can I raise/lower the resolution on the Linux and x86 machines? When I start X, my windows don't fit all the way on my screen -- how do I fix that?

You may be able to increase or decrease the resolution by typing "Ctrl Alt +" and "Ctrl Alt -" in X, using the + and - keys on the number pad rather than the ones between '0' and 'backspace'. If your windows are hanging partly off your screen, Ctrl Alt + will fix it; they're set up for a higher resolution than the default. If you have troubles with the default resolution on a machine in your office, please email gripe [at] cs [dot] utexas [dot] edu describing your problems and specifying your machine and we will attempt to fix things. We can typically change the default resolution or refresh rate upon request.
