[manjaro] [laptop] [hybrid graphics] after some update hdmi port is not used anymore

Last time this happened, I freaked out, after a couple of hours I was able to get it back to normal by following those steps:

• install a newer kernel
• go to Manjaro settings/Kernels
•  
• install the most recent one (not experimental if possible)
•  
•  enable grub at startup
• sudo vim /etc/default/grub
• replace grub_timeout_style=hidden by grub_timeout_style=menu
• save
• sudo update-grub
• restart
• select the new kernel installed
• go back to the kernel settings and remove the current one
• restart
• go in Manjaro Settings/hardware
• click the button "install proprietary drivers"
• restart
• go back in Manjaro settings/hardware
• right click on each free drivers you have an select "reinstall"
• 
•  
•  
• once this is done remove the proprietary drivers you've previously install and restart, this will switch with the free drivers and hopefully things will be back to normal.
• I think something weird happen with some updates of the graphics drivers, from time to time it just wipe some part of the configuration, that is the only process I know to make it back to normal.
• I just hate messing with this...
