Welcome the first issue for this project @jcifuentesz ! I'm sorry for replying so late, I've been quit busy lately.

Thank you for posting detailed information. In short: I have looked for the solution for the AMD GPU configuration, but no luck so far :(

In detail: VirtScreen currently works best with Intel graphics driver xf86-video-intel. Because this seems to be the only graphic driver that supports "Virtualheads" option. The "Virtualheads" create reliable fake displays (e.g. VIRTUAL1) for VIrtScreen. This also is known to work on laptops with Nvidia GPU + Intel integrated GPU by using Bumblebee project. I am not sure how this can be done on AMD GPU laptops, since I don't have any hardware to test with. I am still looking for the solution but there is no guarantee. Anyway, I will look through your logs and will see what I can do.

If you don't care much about the GPU performance (and you don't play games on that laptop), one possible solution for now is disabling amdgpu driver and installing xf86-video-intel driver. I don't know if this is possible on your laptop.

Hey @kbumsik

• 1st of all, congrats [and thank you :hankey:] for this project! :100: :vulcan_salute:

• 2nd, I'm facing this same issue, although my GPU isn't AMD. I've posted some details on pastebin: xrandr -vrbs // lspci // Xorg.0.log

and also...

$ hostnamectl
...
Operating System: Ubuntu 18.04.2 LTS
            Kernel: Linux 4.15.0-45-generic
      Architecture: x86-64

• 3rd, I feel really stupid, but I can't seem to figure out what is the issue.. I've tried also with cli method and got the following message:

  $ virtscreen --right --hidpi
  Creating a Virtual Screen...
  Error:  No virtual screen name found

  Am I missing any param for the command, like the virtualhead name? Or it outs this because it's not recognizing any vhead?

I've also tried #this fix suggested by you, but to no avail..

Sorry to bother, but can you help me figure this out? Thanks in advance!
