I have a dual boot system with Manjaro-i3wm and Windows 10. The second monitor doesn’t work with Manjaro, works with windows. It is not detecting the HDMI connection. Can someone please help.
Here is the the output of some commands: xrandr

@mithrial Maybe, because lshw -C video outputs one unclaimed. However, I have installed nvidia drivers, not sure what’s wrong.
I installed from the GUI utility provided in Settings manager, also using sudo mhwd -a pci nonfree 0300.
No /dev/i2c devices exist.
ddcutil requires module i2c-dev.
Strange. You have not installed ddcutil either you 'll get an output like this one (but for one monitor for the moment). Install i2c-devices and try again.
I suspect an issue/conflict with intel/nvidia drivers. That really strange that we only see one DP port.
To my mind, I think that your second monitor is on the nvidia card and like it is intel the master it is normal to see only monitor. The solution is to desactivate intel.
Perhaps with Prime ?
Another question: are you using a displaylink device (the second monitor) ?
I am having errors installing i2cdev. When I try to make the files, I get make[1]: *** [Makefile:709: install-am] Error 2 . Not sure why.
I do think it is some problem with drivers. I will try shifting to only NVIDIA drivers using optimus prime or prime as you suggested.
Optimus Prime says nvidia module does not seem to be available for the current kernel.
I added the line i2c_dev to /etc/modules-load.d/modules.conf, and when I now do sudo ddcutil detect
I get:
sudo ddcutil detect

are you able to edit a textfile with sudo-rights ? if not we’ll help you.
what i really recommend to you is to switch to nvidia permanently. in this case i’m 100% sure it will work. it seem’s that acer really uses some electrical engineers that don’t know their job and that causes always trouble with this hybrid-mode-acer-BS.
if you want please install optimus-manager from the package-manager, but only installing this packet, do not switch anything that eventually will break your system. let me know if you want to try this.
I tried switching to NVIDIA using optimus. However, I get nvidia module does not seem to be available for the current kernel. when switching. i tried trying a new kernel(not real time), but still nothing changes.
On top of that, when I switch to NVIDIA, it starts the session but optimus manager is not able to open when NVIDIA is selected. I did the mistake of starting optimus on NVIDIA on boot, so now I am not able to even open optimus.
optimus-manager
ERROR: the latest GPU setup attempt failed at Xorg pre-start hook.
Log at /var/log/optimus-manager/switch/switch-20220820T120049.log
Cannot execute command because of previous error
well optimus-manager is active, that’s fine. now you check with
echo $XDG_SESSION_TYPE
that it is x11. it is, but you should know that nvidia and wayland is a mess, always use x11.
after you checked this you will edit /etc/default grub . you will find a entry
GRUB_CMDLINE_LINUX_DEFAULT="
you will add to the existing entries the following two one’s
