Today evening I just notice about Teamviewer 8 Beta version problem on Fedora 18. First time I try to open the teamviewer It was working normally then when I tried to open second time on my PC again. It completely not working. Error was : " teamviewerd service not started. Please start service then try again."
The problem was on teamviewer , teamviewer already have this "service" file on "teamviwer" folder under "/opt" but It must be copied to here "/lib/systemd/system"
So simple solution on terminal
cp -r /opt/teamviewer8/tv_bin/script/team/teamviewerd.service /lib/systemd/system/
service teamviewerd start
and Teamviewer will be work. Also for make it permanent (add as a daemon)
systemctl enable teamviewerd.service
And have good teamviewer also Fedora using :)
