Linux Mint 19 switch to Intel graphics

GPU Unix Graphics Linux
#1

Hi all, I have a MSI GL62M Laptop, I install Linux Mint 19 Cinnamon with dual boot. I am trying to switch to Intel Graphic but I couldnt. When I switch sometimes it freezes and nvidia-x-server-settings doesnt work. I purge and reinstall nvidia drivers. How can I fix this?

Here is my inxi -Fxz output:

Please try using kernel parameters

acpi_osi=! acpi_osi="Windows 2009"

Well, I reboot and use it and appear that System doesnt freeze. But the led indicator from my MSI power button is still orange. (Think needed to be blue if Intel is working as Graphic)

However I cant open my nvidia server settings to check it so I did this:

roberto@roberto-GL62M-7RDX:~$ sudo prime-select query
[sudo] password for roberto: 
intel

Well, is there another possibility to check if Intel Graphics is correctly working?

Thank you.

#4

Running

glxinfo |grep vendor

should return

server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
OpenGL vendor string: Intel Open Source Technology Center

That led indicator might be a software triggered one, only available through Windows software, don’t know though.

#5

Well, that is exactly that glxinfo |grep vendor return.
So I can assume that Intel is working, sure? All time I think led indicator is hardware and not software.

Hope now, my battery improve his performance.

Thanks for your time.

#6

To check that the nvidia gpu is off, run

sudo cat /proc/acpi/bbswitch
#7

Here is my output:

roberto@roberto-GL62M-7RDX:~$ sudo cat /proc/acpi/bbswitch
cat: /proc/acpi/bbswitch: No such file or directory

Its the correct output?

#8

The maybe Mint is now using runtime pm
cat /sys/bus/pci/devices/0000:01:00.0/power/runtime_status
should return
‘suspended’

#9

Well, not luck with the return. I show you:

roberto@roberto-GL62M-7RDX:~$  cat /sys/bus/pci/devices/0000:01:00.0/power/runtime_status
active
#10

I don’t know what kind of power management Mint currently uses, better ask that in the Mint forums.
You could also try to revert to a bbswitch based method:

So basically I am using Intel Graphics but still on Nvidia?. I try to ask but its difficult to understand why are big differences among linux distro. I didnt know if I should to install another Distro to improve battery usage beacuse still on for 2 hours.

#12

You are using the intel gpu but the nvidia gpu is still on so it consumes power though not used.

#13

Well, I read your link and I see this: https://github.com/timrichardson/Prime-Ubuntu-18.04

Could work, I will try. Do you think its better update nvidia to the lastest versión from Update Manager?

Thanks for your patience
