Quartus II keeps crashing on Ubuntu 14.10

It ended up crashing in spectacular fashion a couple of times (windows vanished) last evening during a signaltap session, so I'm giving up on 14.1 again for a while.

I would seek support but since Ubuntu isn't supported and I don't feel like taking the time to test this on Centos (some of the previous crashes were happening on Centos 6.5/6.6) right now, it probably will not provide any useful result. These published tweaks certainly helped get further than I had gotten before though.

One thing that still bugged me is that wile I think it was only "warnings falsely classified as errors", the result of the DDR pin assignment script execution is a little discouraging. It throws a lot of red text up on the console.

To anyone who has had success on Ubuntu, have you exercised the tools pretty thoroughly and things still seem stable or are you just doing compiles and aren't deep in yet?
