USE flags for net-im/skypeforlinux Instant messaging client, with support for audio and video
||Triggers a paxmarking of the main skype binary|
emerge --ask net-im/skypeforlinux
Additional USE flags
The following settings will need to be in /etc/portage/package.accept_keywords/skypeforlinux or some equivalent.
echo "=net-im/skypeforlinux-18.104.22.168 ~amd64" >> /etc/portage/package.accept_keywords/skypeforlinux
Edit your pinentry usage in this way.
echo ">=app-crypt/pinentry-1.0.0-r2 gnome-keyring" >> /etc/portage/package.use/pinentry
and then just install the package.
Auto-launching at KDE login
For some reason, KDE cannot remember Skype in the session it saves upon log out. This workaround will fool it into saving Skype in the session.
To make the Skype main window (but not chat windows) go to a desktop or any other features of Window Rules with KDE, use this regular expression under Window Title in the settings window:
No video (despite video drivers being installed/loaded)
It is possible, that your user does not have privileges to access video device. Example privileges:
ls -al /dev/video0
crw-rw----+ 1 root video 81, 0 Nov 25 22:03 /dev/video0
Add each Skype user to the video group:
gpasswd -a larry video
Where larry is substituted for the appropriate username.
