I recently bought aa Razer Blade Stealth laptop which I'm having issues with Elementary Loki on. This laptop uses the 7th gen Intel Kaby Lake chipset with an HD 620 graphics chip and a HIDPI touchscreen (12.5" 2560x1440 QHD).
I can boot to the installer without issue and proceed through the install (even the touchscreen works!). Once installed It boots to the login screen (lightdm) and I can move my mouse, type password etc without problem, but as soon as I login the machine crashes with a garbled screen.
While at the login screen I can alt-F1 to another console and login there without issue. while there I've checked a bunch of logs but they all end abruptly, I'm guess it crashes before it has a chance to log anything.
Things I've tried:
- explicitly setting an xorg.conf with tweaks from the Arch wiki (https://wiki.archlinux.org/index.php/razer#Graphics_Drivers)
- Upgrading the kernel to 4.8 (as I heard it has many Kaby Lake fixes in it)
- Stopping lightdm and running startx from a console
Every time a crash as soon as the desktop starts to load.
I've installed Xubuntu 16.04 (as I had the ISO handy) and that works without issue - I can load the desktop fine (though the HIDPI support is a bit poor). From there I added two elementary repos, ppa:elementary-os/stable and ppa:elementary-os/os-patches and using apt installed elementary-theme elementary-icon-theme elementary-default-settings elementary-desktop (as per this post - https://askubuntu.com/questions/766673/pantheon-on-ubuntu-16-04) but it still crashes as soon as I try and log in to Pantheon (XFCE still works fine).
I'm out of ideas - are there any commands I can pass to the kernel at boot, some sort of safe mode, or debugging? It's strange that lightdm works fine, XFCE works fine, but pantheon crashes hard.
Sorry for the essay - was trying to get as much info in as possible!
EDIT: Added the fact it is a HIDPI display
