No need to reboot.

Let me explain what the last couple commands actually did:

The 'xrandr' command asked the computer what it thought valid display
modes were.
The 'cvt' asked the computer what it thought the best settings were
including refresh rate, modes, and sync settings were best for running
at 1280x1024 resolution.

The next things to run are:

xrandr --newmode "1280x1024" 109.00  1280 1368 1496 1712  1024 1027
1034 1063 -hsync +vsync
xrandr --addmode VGA 1280x1024
xrandr --output VGA --mode 1280x1024

Once you run those three commands, the monitor should be set to
1280x1024 resolution.

NOTE: If you're going to be running these commands on several
computers you'll need to run 'cvt <desired width> <desired height>'
for each different computer and monitor combination and modify your
'xrandr --newmode' command accordingly.
