System crashes on reboot or poweroff



Im using manjaro with i3 and since the last update, whenever im doing



sudo systemctl poweroff

The system crashes and the screen freezes.

On doing

mhwd -li
im not getting any output

I use Nvidia gtx-1050 and this is happening since recent driver update for nvidia


Is this a hybrid/optimus laptop or is that a dedicated gpu? If it is a dedicated gpu, try going into your BIOS and disabling the intel GPU.


I would also suggest installing and testing both older and newer kernels. Try at least these kernels 4.14, 4.19, and 4.20. Install kernels through Manjaro Settings Manager, and always have at least two kernels installed at all times for safety.


It uses optimus graphics.


The issue persists on all the 3 kernels


Well then if that’s not an helping I expect your best option would be to downgrade your video driver. Hopefully you have working driver versions in your package cache.


are you using the free nouveau bumblebee? nonfree nvidia bumblebee? or did you manually setup Prime or optimus-manager?
mhwd -li (i must be tired)

also does the same thing happen (no output) when you try inxi -G or nvidia-smi ?


Getting stuck at both

inxi - G




I’m using nvidia bumblebee


Try to delete xf86-…-nouveau.


i was almost certain you were gonna say nouveau, it acts like this for any call to the gpu. you can try logging out of you desktop environment and ctrl+alt+f2 to get to a tty and see if mhwd will let you re-install drivers.
(make sure of which drivers you have installed, mhwd -li should work from tty)

sudo mhwd -r pci video-hybrid-intel-nvidia-bumblebee
sudo mhwd -a pci nonfree 0300
sudo systemctl enable bumblebeed
see how it goes, if not i think @tbg 's idea would be the way to go considering it happened right after an update.

also check cat /etc/modprobe.d/*
“blacklist nouveau” should be in there amongst others.


I’m unable to switch to tty. After logging out from i3wm, when I press ctrl+alt+f2, I’m getting a blank screen.


ctrl+alt+f3 or f5-6-7-8
you should be able to get to tty but if not you can boot up a manjaro live usb and
manjaro-chroot -a
to chroot into your current install and do the necessary steps.


Here’s the output of

cat /etc/modprobe.d/*

blacklist r8169

Is everything okay?


those are listed twice, but i dont think thats the problem. maybe a symptom of the problem.

ls -la /etc/X11/mhwd.d
ls -la /etc/X11/xorg.conf.d

it would help being able to see what drivers mhwd has installed. if you cant get to a tty to check, chroot from a live environment and post the outputs of mhwd and mhwd -li


Outputs that you asked

ls -la /etc/X11/mhwd.d

mhwd and mhwd -li give no output and the terminal gets stuck


ok, your not using bumblebee. it looks like you have optimus manager installed. again, without more info, there isnt much more i can suggest to help you. get yourself on a manjaro live environment, connect networking and
manjaro-chroot -a
so you can actively provide more info.

alternatively you can try changing the startup mode so that manjaro runs on either intel or nvidia.

You can also specify which GPU you want to be used by default when the system boots :

optimus-manager --set-startup MODE   
(replace MODE with either intel or nvidia)

read through the tutorial and linked pages and see if anything you did may of caused this.

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Thank You


gave up on optimus-manager and went back to bumble bee i see. optimus-manager can be buggy for some people (myself included).

note: it you want your nvidia information to come up with inxi or nvidia-smi you can run them with primusrun or optirun. or you run glxspheres64 while you do anything that requires the nvidia to be on to read.

primusrun glxgears64(leave it running)
inxi -Gxxxz
of course you could also run either one of those commands with opti/primusrun


Hi, didn’t solve my problem yet. Still facing issues
