Linux is not supported

[divanshu-go]

@louis030195 I tried it on Ubuntu, Fedora, Arch linux

even tested it on X11 and Wayland

it used to work 2 weeks ago

I saw that
the linux integration test is failing from past 2 weeks

this PR bumped the version of xcap and thus broke compatibilty with linux

#1272

the last it worked was this e6c9d04
