Linux and Windows – Using Linux Machine as a Monitor for Windows

hardwarelinuxwindowsxorg

What software do I need if I want to use an old laptop running Linux as a second monitor for a Windows 10 PC? Both screens shoud be in one workspace.

Best Answer

After a bit of research I found a program called Spacedesk. The primary machine has to be Windows, but the secondary can be a phone, tablet, or PC running Windows / Linux.

I3wm: two monitors, one browser per monitor (dual head kiosk)

You could assign specific class names to your Chromium instances and tie them to workspaces. So with 2 monitors config:

workspace 1 output HDMI1
workspace 2 output HDMI2

for_window [class="^chromium-no-1$"] move workspace number 1
for_window [class="^chromium-no-2$"] move workspace number 2

You'll need to start 2 browser instances with specific class values:

$ chromium-browser --class=chromium-no-1
$ chromium-browser --class=chromium-no-2

Centos – Multiple monitors on linux

I have found a solution here https://askubuntu.com/a/419614/217214. There is one thing to be careful of. xrandr reports HDMI-1, HDMI-2 and eDP-1 outputs on my graphics adapter. However, I had to use HDMI1, HDMI2 and eDP1 in xorg.conf file.

I did not use /etc/X11/xorg.conf file. I added a file 20-screens.conf to /etc/X11/xorg.conf.d/ directory. The file is very similar to the one provided in the solution https://askubuntu.com/a/419614/217214. So I don't see the point of repeating it here.
