I have Awesome Community Edition. Because it was causing app freezing, I removed the Intel driver with:
sudo rm /etc/X11/xorg.conf.d/20-intel.conf
sudo pacman -Rns xf86-video-intel
Now I am on modesetting video driver, based on this:
grep drivers /var/log/Xorg.0.log
[ 4.467] (II) Loading /usr/lib/xorg/modules/drivers/modesetting_drv.so
And, despite tearing, I have no more freezing. However, I discovered this mhwd thing and in particular:
mhwd -li
gives
video-linux 2018.05.04 true PCI
Should I follow up with:
sudo mhwd -r pci video-linux
sudo mhwd -i pci video-modesetting
and what would that change in my system?
