Quartus II keeps crashing on Ubuntu 14.10

That is good to hear. I had done some work with the SoC EDS stuff last year but nothing lately; otherwise everything I've done with 14.02 has been fairly reliable. I'm on Ubuntu 14.04LTS and probably staying there for the time being. I have kept CentOS VM's running because I could never get the CV SocKit GSRD yocto stuff to build properly under ubuntu 14.04 (or 13.10?); I had success under 12.04. I didn't investigate it too deeply. I had higher expectations for enterprise linux (unrealistic perhaps) and the laptop hardware support was not good for me; Ubuntu on my main machines has been a pretty good working OS.
