I have a Gt 220, the gigagbyte version and I only using linux OS. I first installed ubuntu 9. something (can't remember the exact name), the free driver wasn't really working (really low resolution ...) so I installed the nvidia one the manual way. It didn't work but after one driver reinstall it did work nearly normally on boot there was an annoying bug the OS first loaded normally then but instead of the user choicing screen I had a black screen, then if I did a rebboot the hard way with the mobo button I would get the normal load. While annoyed I got on with the problem. 3 or 4 month later I did a new install of trisquel an OS mostly based on ubuntu. Same story I installed driver the manual way they worked but as previously I had to do a rebbot before acessing to the OS. 2 month later I reinstalled ubuntu the 10.10 version. this time I installed nvidia driver by letting ubuntu install proprietary driver by itself and once again the same problem. This start to get annoying,the two first time I thought it was a problem with my driver installation, now I think there gotta be a problem somewhere. To sum the the graphic start after the OS loading only if the Pc was on before: so if it is on reboot there is no problem but every fist time booting afer being turned off no graphic.
