Failing to copy to clipboard with version 0.5.2 on X11 about normcap

[dynobo]

Thanks for reporting this, @rwese ! You actually scored a Hattrick here, pointing to three issues 🙈 :

1. xclip is used to copy to clipboard on Xorg, instead of the default Qt-method (like in NormCap 0.4.x)
2. The warning text doesn't fit, as your Linux does not run Wayland
3. xclip should be bundled in the NormCap flatpak (no need to install it on the system), but it seems like it isn't detected correctly.

1.) and 2.) should be fixed in v0.5.3, which I'm preparing right now. 3.) might take longer, but that shouldn't bother you, as on Xorg xclip should not be used anyway.
