Start with black screen after non-free nvidia-driver installation

Hello everybody,
I'm new to manjaro and linux. I've recently installed Manjaro XFCE Edition (17.1.11) on my laptop. The system seemed to work fine until I installed the non-free nvidia-driver and ran nvidia-xconfig in terminal.
I can see black screen with a underscore character in the top-left corner instead of login page.

I've tried some solutions in similar topics from the forum. Such as:

  • edit xorg.conf file
  • set discrete card as primary GPU
  • disable on-board GPU in BIOS(not supported by BIOS in my machine)

Sadly, it's not gonna to work. Maybe I did something wrong, but I couldn't find it.
However, it's obviously that the nvidia-driver has already installed and the X server has been loaded without apparent errors.

I find this line from /var/log/Xorg.0.log :
[ 7.324] (WW) NVIDIA(0): Unable to get display device for DPI computation.

It's telling me that nvidia-drive can't find the "display device" ? Should I config the nvidia-drive to know where my "display device" placed? Or it is just an insignificant information.

Can anyone help me to figure out my issue? Any idea will be appreciating.

Here are some information about my environment:

English is not my native language, please excuse potential typos and ill-formed expressions : )

Please tell me if any addition information is needed.
Thanks for any help.

What information already exists

According to inxi output you have a laptop with Hybrid GPU aka dual GPU. What you installed and what you did will not work.
You either install and use bumblebee also look here how to troubleshoot ... or use PRIME

At your place I would try to get my system running again and then try other drivers or kernel. The following link points to an other GPU but the steps should similar.

I guess you used mhwd or Manjaro Settings Manager for installing the driver. If so, it would be enough. No need to run nvidia-xconfig. This probably created this mess.
You tried to administer your system without even reading any Tutorial, Manjaro Guide, or Archwiki. Or have you?

You could try re-installing the driver (remove and install).
Use MSM or with mhwd:

mhwd -li --pci
sudo -r pci <the name from previous output>
sudo -a pci non-free 0300

Sorry to wasted your time.:frowning_face:

I had found that when I excute mhwd -li, which means show installed driver configs, I got a driver config list without video-nvidia. So after I reinstalled the nvidia driver using mhwd and set PRIME mentioned in this page:


I got my desktop back.

It's wierd that the mhwd -li command return no installed nvidia driver information after my first installation.Maybe I should not excute nvidia-xconfig casually.

Anyway, thank you guys for your information, that's really help a lot(I'll remember to check both manjaro documentation and archwiki next time, thank you for your sugeestions @AgentS ).
Thanks!!

By the way, I get another 'black screen' issue after I fix this 'black screen' issue.

Another 'black screen' issue

I login in by input my password in LightDM GTK+ Greeter window(the login page) and enter my desktop. Then if I click Whisker Menu(default at the left side of the panel with the manjaro logo) and click Lock Screen button, I get a black screen with a quick-flashing underscore character in the top-left corner.
I can press ctrl+alt+Fx(i.e. F2) to get a TTY, if I do, the TTY screen will be instantly replaced by the above-mentioned black screen without exception. It's preventing me from typing any character(direct type password to login didn't work). The only thing I can do is pressing power button on my laptop to 'reboot' my machine. Every thing seems good except the Lock Screen button.

Clicking Switch User button or Log Out -->Suspend button result in the same issue, but the Log Out -->Log Out and other button in Whisker Menu wil not.
The auto-suspend function also cause thie issue.

I know it's not a critical issue, but it's quiet annoying, isn't it?
Should I open another topic?

You should, so others can discover and benefit.
Whisker menu has those options configurable. Check what you have and change/test what works. Better create another topic, it's interesting.
