I just updated my system which broke the tuxedo-control-center (and probably more, see below).
Trying to start the application results in the error message:
Communication with tccd service is unavailable, please restart service and try again.
Indeed the tccd.service is not running and trying to (re)-start it via the systemctl does not work, journalctl -u tccd gives:
Jul 18 18:54:50 infinitybook systemd: Started TUXEDO Control Center Service.
Jul 18 18:54:51 infinitybook tccd: Pkg: Error reading from file.
Jul 18 18:54:51 infinitybook systemd: tccd.service: Main process exited, code=exited, status=1/FAILURE
Jul 18 18:54:51 infinitybook systemd: tccd.service: Failed with result 'exit-code'.
This persists even after reinstalling the related packages, in particular i followed the steps described in a recently posted Tutorial.
As a probably related side note, trying to restart the service breaks some major parts of the system, e.g. running pamac update afterwards gives:
** (pamac:3342): WARNING **: 19:06:37.538: transaction_interface_daemon.vala:52: failed to connect to dbus daemon: GDBus.Error:org.freedesktop.DBus.Error.LimitsExceeded: The maximum number of active connections for UID 1000 has been reached
Authorization not available. Check if polkit service is running or see debug message for more information.
** (pamac:3342): CRITICAL **: 19:06:37.750: pamac_daemon_start_get_authorization: assertion 'self != NULL' failed
Additional Info: I run the plasma version of Manjaro on kernel 5.15.
I would really appreciate any ideas that might fix this problem.
I have the same problem as OOP after the latest updates (tccd crashes with Pkg: Error reading from file.), but without the other problems (pamac and the rest of the system is running ok before and after I try to restart tccd).
(KDE Plasma, Kernel 5.18.12-3, everything up-to-date)
I guess it is a problem with the tuxedo-control-center-bin package , it got an update 4 days ago.
@Op: can you confirm that you are also on 1.1.5 for the tuxedo-control-center-bin package?
There is also an (old) issue in their github  with a similar problem, unfortunately without resolution
All in all kinda annoying because it seems without tccd my fan is running on full power all the time -.-
if you bought a tuxedo-hardware i would recommend that you ask for support also at tuxedo. they sell their hardware with this software and they should be reliable for it. if tuxedo want’s to get a popular linux-brand then it’s a must that they’ll help and assist if their software troubles.
I have the same issue as @TheCissue using the package from extra, on a Tuxedo Pulse 14. Opening the GUI failed and the fan would not stop. I have tried the same steps without luck. I ended up using Timeshift to restore a previous point.
@Olli I totally agree with your expectations from Tuxedo, but from experience Tuxedo is not interested in providing software support. I had an issue with the tuxedo-touchpad-switch package, I submitted a ticket with them and their reply was the following:
We only give hardware support for our Manjaro Notebooks. The Tuxedo packages for Manjaro are managed by Manjaro or the community.
