Can we run Quartus II on Ubuntu?
I've successfully installed Quartus II on Ubuntu. I followed mainly those instructions:

http://www.philpem.me.uk/elec/fpga/quartus-ubuntu/

IIRC I had to modify somethings, I think it was the udev-Rules and the symlink from /bin/sh (defaults to /bin/dash in Ubuntu/Debian but Quartus II expects it to be /bin/bash).
