Broke my display driver!

yesterday I was playing with display driver and actually tried to install AMD driver by ViOLO :neutral_face:. I don't know why I did that :frowning_face:. Anyway I installed

  1. vulkan-radeon-noglvnd 18.3.2-1
  2. vulkan-intel-noglvnd 18.3.2-1
  3. opencl-mesa-noglvnd 18.3.2-1
    But after that some problem were occurring while starting Manjaro. It wont start in the first time but after a hard reboot It'll start normally so I thought I'll remove what I installed. But now after removing those 3 drivers, the desktop effects is no longer working. No animation is working.

Here is what my looks like,

I've tried to force reinstall display driver using sudo mhwd -a pci nonfree 0300 but it gives me `

Skipping already installed config 'video-linux' for device: 0000:01:00.0 (0300:1002:6600) Display controller ATI Technologies Inc Mars [Radeon HD 8670A/8670M/8750M]
Skipping already installed config 'video-linux' for device: 0000:00:02.0 (0300:8086:0416) Display controller Intel Corporation 4th Gen Core Processor Integrated Graphics Controller`

I tried restoring from time shift backup but that didn't work as well.
I'd really appreciate if anyone could guide me regarding how to fix the problem.
Thank you.

check which drivers mhwd has installed, you should only have video-linux
mhwd -li

manually remove whatever video drivers are listed and install video-linux again instead of just reinstalling it. both amd and intel drivers are part of the "free" package, dont try to use nonfree

sudo mhwd -r pci video-linux
sudo mhwd -a pci free 0300

and also check these 2 directories to make sure that aur package didnt leave behind a xorg configuration that might be causing issues


Hi Thank you for the reply. Sorry couldn't reply you earlier. I had re-installed Manjaro again and you know the rest :grinning: it's solved. Now a days I'm doing all the testing stuff in VM and if it works then I implement them on my main machine.
