Primus could not load gpu driver

Yeah sorry about that. Brainfart. I meant if you used mhwd to change the kernel?
because that install all the nessesary modules for nvidia graphics aswell.

Couldn't it be this "simple" TLP error which prevents nvidia from loading when used battery (even once)? If so, there is an easy fix for that:

Find output of: $ lspci | grep "NVIDIA" | cut -b -8

Open: sudo nano /etc/default/tlp

Put input of first command into: RUNTIME_PM_BLACKLIST so it can look like:



Hi back guys,

Here it is some news :

I tried to set the RUNTIME_PM_BLACKLIST at 01:00.0. (That was the output of your command)
Unfortunately, no change. So I have commented the whole line. (Like it was setted before)
In any case, thanks for the tips :slight_smile:

I didn't used mhwd-kernel to change the kernel, but the GUI. (Settings/Manjaro Settings Manager/Kernel)
It has installed some additionnal stuff, like ndiswrapper and bbswitch.
I suppose it's good. :slight_smile:

I always had this PCIe bus error and I never understand what it tells. May you give some details about it ? :slight_smile:
Indeed, the new dmesg is cleans of this message.

Unfortunately, bumblebeed doesn't seems to work better. :confused:

Into the dmesg log, I found another error. Could the issue be related to that ?
[ 0.956952] ACPI Error: No handler for Region [EC__] (ffff8802760eb5a0) [EmbeddedControl] (20160930/evregion-166) [ 0.956959] ACPI Error: Region EmbeddedControl (ID=3) has no handler (20160930/exfldio-299) [ 0.956963] ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC._REG] (Node ffff8802760ec438), AE_NOT_EXIST (20160930/psparse-543)

Have a good week-end morning !

Cheers :slight_smile:

IMO cause you have major issue in ACPI DSDT Table (ACPI ERRORS for SB.PCI0.LPCB.EC._REG) bbswitch can ON NVIDIA card but kernel cannot handle them at all).

Why you have double variables in:

Command line: BOOT_IMAGE=/vmlinuz-4.10-x86_64 root=UUID=29914461-0fc4-413a-bcb0-eff0d38d2445 rw pci=nomsi quiet splash pci=nomsi quiet splash resume=UUID=c423e44a-2435-4081-b93d-cdabc971148e

Paste grub conf:

cat /etc/default/grub

Check command:

optirun nvidia-smi


The double variable is due to the duplication of those values into GRUB_CMD_LINE_DEFAULT and GRUB_CMD_LINE
Here it is the head of the grub file

GRUB_CMDLINE_LINUX_DEFAULT="pci=nomsi quiet splash resume=UUID=c423e44a-2435-4081-b93d-cdabc971148e"
GRUB_CMDLINE_LINUX="pci=nomsi quiet splash"

(I did this duplication. Shouldn't I do it ?)

And below, the output of optirun nvidia-msi

[ 407.104220] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver
[ 407.104287] [ERROR]Aborting because fallback start is disabled.


Change from

GRUB_CMDLINE_LINUX="pci=nomsi quiet splash"



Update grub:

sudo update-grub


Check OLDER kernel (4.1 kernel series if 4.4 and newer have issue).

Oops, where's my head today. Sorry :confused:
Here it is the output of dmesg while running 4.1.

Unfortunately, I'm not able to reach the GUI with this kernel. (I used tty2 to get this output)
And with kernel 4.4, it didn't notice some errors. But primusrun/optirun still cannot load secondary GPU


Please using for now Linux 4.10 (lastest).

dmesg while running 4.10.

New bug reported upstream:


MSI made crappy Firmware :scream: (ACPI Errors) and using crappy sub chipsets :scream:

Kernel 4.10 only works with Nvidia 378.13 which isn't available yet to us.

When I boot into 4.10 currently, it crashes with traces:

Sorry for the delay of this answer. I took the time to think and to step back about this issue.
I've done some work, and now it's quite better (I think), but not fully functional. :slight_smile:

Here it's the report of those actions

  1. I booted on a Live environment to use mhwd-chroot. (I don't know why, but mhwd freezed while simply running manjaro)
  2. After mounting the partition, I've fully uninstalled, and then reinstalled, video-hybrid-intel-nvidia-bumblebee, following the step 1 of the manjaro wiki. (You're right @ryanmusante, it has automatically installed Nvidia 375.39)
  3. Following the logs, I ran the following command mhwd-gpu --setgl nvidia
  4. Once more, following the logs, I have edited a new file : /etc/X11/xorg.conf.d/20-intel.conf ; with the following content. (
  5. /!\ IMPORTANT : I disabled bumblebeed with sudo systemctl disable bumblebeed, then exited mhwd-chroot console, and reboot on Manjaro with Kernel 4.4.

Now I'm able to run

optirun nvidia-smi

And here it's the output

Unfortunatly, the final test hasn't been OK yet :confused:
Indeed, after running glxspheres64 I've got the following output :

Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
Xlib: extension "GLX" missing on display ":0.0".
ERROR in line 620:


Hi Yonulya, my laptop has a similar setup (mine is a GE62), and I'm having exactly the same issue like yours. I have updated the BIOS to the latest version (112 instead of 118 like yours) given by MSI but ACPI error persists... but nvm. How do you disable bumblebeed.service ? Is it doable through GRUB?
Thank you

sudo systemctl disable bumblebeed

To only stop the service

sudo systemctl stop bumblebeed

So what I should is that to boot in live environment, then chroot and put in these commands? Since I can't boot into system. Nice pic btw

Oh how I miss the GUI. Thank you for the help. I'm living with my DE now lol

@Yonulya and @Da_Toast , take a look at this thread.

Your problem could be a TLP bumblebee conflict, if so the fix is in the thread.

Hi back guys :slight_smile:

Above all, a small point of my (unsuccessful) work :

  • I tried with video-nvidia ==> Worst idea ever. I wasn't able to reach the GUI.

  • I tried video-hybrid-intel-nouveau-bumblebee ==> Not so bad, but only works with Kernel 4.9 and not compatible with GTX960. So it used only the intel graphics. (Enough to play some light games awaiting to find a better solution)

Thanks for reminding me this.
@michaldybczak has suggested this solution above, and since, I haven't retried it.
I will go back to the '4 days ago' configuration and try again. :slight_smile:

Indeed, when you enable bumblebeed.service, it create a symlink.
I don't really know why, but I seems this symlink freezed our boot.

That's it. If you have some difficulties to use mhwd-chroot, this tutorial of Heart-of-Lion explains very well how to use it.
Note : By using this tool, you can only use the disable option of systemctl. Others options aren't usable while using mhwd-chroot. (Fortunately, that's enough to remove the symlink and reboot without troubles)

I'm coming soon with fresh news about the TLP issue.

Cheers :slight_smile:


That's weird. Finally, I found a kind of workaround, but I don't really understand what's happening.
Execute glxgears or primusrun glxgears returns the following messages :

Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual

But execute optirun glxgears works fine.

[ 4763.107218] [INFO]Configured driver: nvidia
[ 4763.108743] [INFO]Response: Yes. X is active.
[ 4763.108769] [INFO]Running application using virtualgl.

Downgrade bumblebee package to version 3.2.1-16, doesn't seems to have any effect.
Same for setting RUNTIME_PM_BLACKLIST to the value returns by lspci | grep "NVIDIA" | cut -b -8

What's the difference between optirun and primusrun ?
man says one is running program with the discrete video card and the other with the discrete NVIDIA video card.
So what card I'm using ?
