This optional entry specifies the list of video modes to use.
Each mode-name specified must be in double quotes. They must
correspond to those specified or referenced in the appropriate
Monitor section (including implicitly referenced built-in VESA
standard modes). The server will delete modes from this list
which don’t satisfy various requirements. The first valid mode
in this list will be the default display mode for startup. The
list of valid modes is converted internally into a circular
list. It is possible to switch to the next mode with
Ctrl+Alt+Keypad-Plus and to the previous mode with Ctrl+Alt+Key‐
pad-Minus. When this entry is omitted, the valid modes refer‐
enced by the appropriate Monitor section will be used. If the
Monitor section contains no modes, then the selection will be
taken from the built-in VESA standard modes."
I'm guessing that you had a list of modes where only 640x480 was valid
for som reason. When you deleted that there was no valid modes and X
resorted to either your Monitors ideas of supported modes ot the
built-in VESA modes.
