So apparently this is a common problem, however I have been googling this issue for a week and can't seem to fix it. powertop reports ~30W of power when nothing is running, which is too high. I did sudo prime-select intel but that doesn't lower power usage. I rebooted, but system froze before login and I had to prime-select nvidia from recovery to get it working again. I also echoed OFF to bbswitch (even though I don't have bumblebee installed), but it resets to on:
$ sudo bash -c "echo OFF > /proc/acpi/bbswitch"
$ echo /proc/acpi/bbswitch
0000:01:00.0 ON

I am using a Dell Inspiron Laptop with i7 7700HQ and GTX 1050 mobility card. I have also tried the nvidia-430 driver (like maybe newer drivers have less issues), but with that X doesn't even start. So I reverted back to nvidia-410.
I also read some other links such as this and this one that had a modified prime-select script, but none of those have helped me so far.
I have also noticed that glxinfo doesn't work after switching to intel drivers (before reboot). It fails with the following output
name of display: :0
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Error: couldn't find RGB GLX visual or fbconfig
132 GLX Visuals

I but that is probably not related to prime. It might be that nvidia-410 doesn't work at all with prime, and I need some other driver version for the GTX 1050m. I have been at this for weeks, missing my laptop's intel graphics and battery life on my linux. Any help would be greatly appreciated.
nvidia-410seems to carry this issue. I will try to installnvidia-384andnvidia-375and see if they work (hopefully). – Abhishek Agarwal Jul 14 '19 at 19:11
