I'm trying to install Ubuntu Studio in a brand new machine. It has UEFI and Grub2.
Problem is that after a Ubuntu (Studio) splash screen I get a "signal out of range" error. And all I can do is press ctrl+alt+F1 to log in without X.
So, I read things like disabling UEFI and Fast Boot and so I did. That just changed the look and feel of the grub2 menu. But the Out of Range issue remains.
Then, some people talks about using nomodeset. But I just can't find where to put that.
Other people says "edit /etc/default/grub and uncomment the GRUB_GFXMODE=640x480 line". So I did. The I'm supposed to run: sudo update-grub2
Well, that last line won't work. I'm getting this error: failed to get canonical path of /cow
I understand this has something to do with mounting something. Not sure if my new SSD disk (that I didn't format at all, is brand new). Any clue?
Also some people talks about using grub-repair but that seems to work only for people already having a running X environment. And I don't. If I burn a recovery CD all I get is the grub screen.
Finally, there're the ones who talks about compatibility issues with skylake, and mention adding this param somewhere: i915.preliminary_hw_support=1
And I just don't know what are they talking about.
More that all I'd like to understand where is supposed grub to live? In my pendrive? Or is it part of the kernel now? I just don't get it.
Thanks in advance.
