I may be missing something obvious so here's the story so far...
Downloaded the latest Mint iso, ran it live in an old dell machine, (2Ghz Celeron, 2Gb ram, onboard graphics intel 845, plenty of HDD space)
Works perfectly (I'm using it now)
Installed it dual boot with winblows xp, installation went fine then after reboot I get to the log in screen, after entering username and password I get a blank screen, the only error message I get is,
/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256
Any help or pointers much appreciated, have had a search here but have not found an answer yet...
