I have dual Xeon X5675 processors in my Ubuntu 16.04 machine.
I tried clicking the "Using Processor microcode firmware for Intel CPUs from intel-microcode (proprietary)" option in "Software and upates" and clicking Apply Changes. The software and upates page then told me to reboot, so I did.
After the reboot, I could not log into Unity anymore, as the screen just flicked back to the login screen. I managed to fix the issue by reinstalling the NVIDIA 375 drivers for my Quadro 4000.
Looking at the Software & Updates page, the Processor microcode is not being used, so it looks like the installation did not work.
So...
Does it mater that I don't have the Processor Microcode installed? What errors am I likely to get without it?
Can or should I install it manually, or should I just keep on going until I hit a problem?
