HOWEVER, if you pre-seed a startup.cfg file
Code:
cat ~/.Heroes\ of\ Newerth/game/startup.cfg 
SetSave "vid_bpp" "32"
SetSave "vid_refreshRate" "60"
SetSave "vid_resolution" "1920,1080"

HoN will start just fine.

Mixed results from IRC atm. Some crash, some don't. I am running the latest and greatest nvidia drivers and xorg so whether this is related (ie could hit other distro's soon as they catchup, ie by March 2012 at the latest)
