I succeeded to run SDR Transceiver : Raspberry Pi 2(Linux/Jessie)/Soft rock
(Ensemble RXTX) with quisk(4.1.1).
Startup quisk.py is as follows..
1. Start RPi by power on
2. RPi GUI appears initially
3. Open “LXTerminal”
4. Run quisk on LXTerminal
I’d like to startup automatically for above sequence.
I tried as follows…
-change to CUI mode by the command
systemctl set-default multi-user.target
-“autologin” symbolic link
ln –fs /etc/system/system/autologin@.service /etc/system/system/getty.target.
#add to start “quisk” automatically
sudo python /xxx/quisk.py &
(here “/xxx” is the directory which “quisk.py” exists)
result: cause error
message is “unable to access the x display, is $DISPLAY set properly?”
Please let me know how to solve the problem.
