I have been getting failures when performing software upgrades in LTS 16.04 with kernel 4.4.0-45-generic. The error goes something like "Error! Bad return value for ... i915 ...". The i915 make.log file is telling me that the recipe for "/var/lib/dkms/i915-4.3.3-4.2.0/2/build/drivers/gpu/drm/i915/i915_gem.o" and "/var/lib/dkms/i915-4.3.3-4.2.0/2/build" failed.
Background: I had installed the Intel graphics driver quite a while ago to fix some issues I was having, per recommendation from this board (lightdm crash back to login Ubuntu 15.10). I'm guessing that the driver I'm using is simply dated and perhaps I need to update the driver or maybe even just remove it, if the Ubuntu-packaged drivers have fixed the original issue.
I'm not terribly savvy in Ubuntu when it comes to drivers, so I'd like confirmation of what the issue actually is and help on how to fix it (shell commands would be nice - a bash-Ninja I am not).
