Hello,
since i didn't want to flood the group with a bunch of problems i'm having, i 
thought it was quite a good idea to collect them in a single post, I hope 
someone can help me out with either any of these.

a short background:
everything started when i've upgraded my VGA from an old GTX560 to a new 
GTX1060, this is when i discovered that qubes, because of nouveau not really at 
a bleeding edge version isn't compatible with the said video card, at a point 
that i can't see anything on screen.
I've solved this by blacklisting the driver and eventually i managed to get the 
system to boot into X, but now i have the following problems:

1) the only supported resolution appears to be 1024x768@75hz, and this is kinda 
frustrating considering i have a full HD display, i'd like to get back to 
1920x1080@120Hz, since this resolution is supported by my display.

2) collaterally, by trying to fix the video issue, i've discovered that the EFI 
partition (i have qubes running from an external USB3 HD) boots stright into 
the OS, and doesn't chainload to GRUB, I have absolutely no idea why, since 
this is something that the installer took care of on its own, but this is 
becoming very limiting, because every update in the qubes dom0, especially when 
related with a new kernel, requires quite a bit of extra work:
- mounting the EFI system partition
- fix the parameters manually in the CFG
can anyone help me out in setting things up properly so that i have a proper 
grub configuration?

3) the last thing: for some odd reasons i'm stuck on kernel 4.4.14 because of 
performance reasons, despite not changing ANYTHING except from the kernel 
version, when running from 4.4.55, X is extremely slow and choppy, mouse lags, 
and to a point that the system is absolutely unusable. any idea on what this 
can be caused by?

Since this is quite an active development community i'm fairly confident that 
across the users and/or devs, someone will be able to help me out with my 
issues, because I'm really enthusiast about this OS, and looking forward to use 
it more, despite the transition is quite complex as of now.

Thanks in advance
