I'm running Kubuntu 17.10 (latest updates at the time of writing).
Everything works fine, but when I try switching from the Nvidia card to the Intel one (for energy reasons), the option - which seems available - in Nvidia X server settings just doesn't work.
Meaning I can click it, but it doesn't "stay selected", in lack of better words.
No syslog entry associated to the click.
A related issue, maybe: in Driver Manager, I if I activate the checkbox stating:
Using Processor microcode firmware for Intel CPUs from intel-microcode and click
Apply, the checkbox stays un-checked after refreshing.
This doesn't come with any useful syslog entry either, aside from
DriverManager_DBus::devices START and
Hardware and drivers

I've seen a lot of posts regarding Graphics cards and issues with various desktops, but haven't found any existing one that can help me.
How do I switch to Intel graphics for power saving in Kubuntu 17.10?
Switching ACPI off for PCI in the kernel parameters on boot (
pci=noacpi) seems to force the Intel driver, but I suspect this won't play well with other PCI-related features, such as power metrics and even shutting down, rebooting, etc.
