tehownt, thank you for your comments. Regarding them https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1265544/comments/6 : >"Christopher, no I don't."
Fair enough. >"Plus, it's important to note, the drm-intel-nightly doesn't _fix_ the issue, it's merely a slight workaround allowing the system to boot, as mentionned in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1263015 as soon as the screen goes blank, the system is lost and reboot is needed." You might be able to WORKAROUND the dimming+freeze issue by disabling screen dim in System Settings (which may have it's own systemd WORKAROUND to get these to take). I'll let you comment further to this. >"Also, the system comes with nvidia 730m yet installing nvidia-331 (on drm-intel-next kernel patch) makes boot fail again (might have to create a new bugreport on that though)." If you patch the default Ubuntu kernel with out of tree branches, especially an experimental testing ground like drm-intel-next, it's not supported.
