Hi,
I have started to use OpenSUSE Leap 42.1 approximately one mount. I have been
supporting BOINC at least 1 years. 
I have installed BOINC unstable (7.6.32) from OpenSUSE software page ( 1 Click
Install page).

I gave these commands before running BOINC(I found these commands from:
https://forums.opensuse.org/showthread.php/518018-Running-BOINC) :

1. systemctl start boinc-client.service
2. /usr/sbin/usermod -G boinc -a username
3. chmod g+rw /var/lib/boinc
4. chmod g+rw /var/lib/boinc/*.*
5. ln -s /var/lib/boinc/gui_rpc_auth.cfg /home/username/gui_rpc_auth.cfg
Finally log out and log in and it takes effect

But When I check Event Log from boinc-manager ( Tools -> Event Log or simply
shift-ctrl-e )

It says " no usable gpus found ". I have installed Amd firepro drivers and also
AMD APP Opencl sdk. But Boinc gives this issue. I searched internet and found a
solution.

"xhost +si:localuser:boinc" after giving this command you need to restart
boinc:

"systemctl restart boinc-client.service" And BOINC founds my gpu and runs
opencl apps.

But I am giving every time this command (xhost +si:localuser:boinc) after log
in.

Where should I add this command to boot with. 
Also I want to enable boinc-client.service not starting by hand. So (xhost
+si:localuser:boinc) should call before starting boinc service (systemctl start
boinc-client.service)
