I have installed ubuntuMATE (Ubuntu 16.04.1 LTS) on a Lenovo B50-30 laptop, seemingly without problem, 'Linux 4.4.0-53-generic' is listed in GRUB2.
It boots through to the login screen fine where the user I set up is present. I am able to log in with my password and the Ubuntu logo shows whilst the desktop is being set up. Once this is complete I briefly see the desktop before the screen fades to black (blank, no backlight), much like I would expect from a suspended system. I cannot recover the screen from here, but if I hit ctrl+alt+del I can hear a system noise, so the OS has not crashed.
If I boot into recovery mode, select to resume normal boot from the recovery menu (it warns me some graphical drivers may need a full reboot) and follow the same login procedure everything works as intended and the screen remains active. If I suspend the system from this point however, the screen never reactivates.
I have checked that the Intel integrated graphics drivers are up to date (they appear to be) and have trawled this exchange and google, trying the various fixes I find to no avail. Whilst the problem can be worked around using recovery mode a real fix is needed.
I tried installing Kernel 4.4.25 following this guide: http://linuxdaddy.com/blog/install-kernel-4-4-on-ubuntu/
But it shows the same problems.
I'd love any advice for solving this problem, it's aggravating to be so close, and yet so far, from a working system. I suspect a simple reconfiguration rather than big error because of the partial working behaviour.
Thanks for your time.
