I don't think you need a driver. It is just that with a VGA connection, X cannot always determine optimum or native resolution. See https://wiki.ubuntu.com/X/Config/Resolution

Note that your video outputs could have different names than shown there, but xrandr should tell you what they are called (and which resolutions are active).

Look through /var/log/Xorg.0.log to see what resolutions X finds. Sometimes it thinks it cannot use certain resolutions, even if they would work. Sometimes cvt does not come up with optimum timings, but once you get something close, and set it with xrandr, you could try fine tuning with xvidtune.

What is the native resolution of your monitor?
