Experiencing this on Xubuntu 14.10 with the ATI proprietary driver with Radeon 270X 2GB. Right now the X server is over 6GB:
root 3444 10.6 44.3 6303840 5457648 tty7 Ss+ Mar14 238:46 /usr/bin/X -core :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
Running Firefox, Thunderbird, plenty of terminals, and things like Cadsoft Eagle (5.12), Saleae Logic (1.1.18), LibreOffice, Evince, etc. Killed *ALL* of them and practically no change in X usage.
