Maybe it's a good time to share this - I just bought a brand-new Dell XPS 15 and it runs Ubuntu like a dream. The only problem I've had is that suspend/resume (i.e. closing the lid) causes a kernel panic, but I've heard that's fixed in the next kernel release.

And the best part - no bogus certs!

I think it's time to apply a higher standard to "runs like a dream."

Regarding the suspend/resume stuff, which version of Ubuntu are you running? I don't have a problem, but I had to do a couple of things to get it working more like a Macbook: http://karlgrz.com/dell-xps-15-ubuntu-tweaks/

I'm running Ubuntu 15.04 and I haven't tried any of those things. My suspend/resume experience isn't like that blog, though - what happens to me is that I shut the lid, the os "suspends", I open the lid again and get an unresponsive black screen and I have to reboot.

This is almost exactly what I've done to set up my machine: http://ubuntuforums.org/showthread.php?t=2301071&p=13382949#... . This thread claimed that the kernel v4.3 fixed this issue, but it still happens for me - I was going to wait until the next 4.4 RC to give it another whirl.

I've had this problem too, in my case it was caused by some clever (way too clever imo) stuff going on that tries to write a bunch of io ports to a safe place on suspend and writes that data back to the various chips on resume. This caused all kinds of trouble.

If your BIOS supports it choose 'sleep' rather than 'hibernate' for suspend/resume. It will be a bit slower but there is far less OS dependent magic going on under the hood.
