Hello.
I would like to run a shell script automatically every time my ubuntu 18.04 installation has landed and I see the desktop manager fully loaded. The script should be executed regarless of the desktop manager that I'm using. To do this I created these scripts :
Created executable file
/opt/rasp/setup-rasp.sh:
Code:
#!/bin/bash
echo "Setting up rasp ...mounting I9"
touch /tmp/rasp-activated
echo mounting I9...wait 20s
sleep 20s
sudo mount -t nfs -o nolock,local_lock=all 192.168.1.6:/home/ziomario/Scrivania/Dati/Data/Nano/I9 /home/zi/Desktop/Work/I9
sleep 20s
qemu-system-aarch64 -M virt -m 2048 -smp 2 -cpu host,aarch64=off -enable-kvm \
-kernel /home/zi/Desktop/Work/I9/arm32/debian11-bullseye/vmlinuz-5.10.0-5-armmp-lpae \
-initrd /home/zi/Desktop/Work/I9/arm32/debian11-bullseye/initrd.img-5.10.0-5-armmp-lpae \
-append 'root=/dev/vda2' \
-device usb-ehci -device usb-kbd -device usb-mouse -usb -serial stdio \
-device virtio-gpu-pci,virgl=on,xres=1920,yres=1080 -display sdl,gl=on \
-drive if=none,file=/home/zi/Desktop/Work/I9/arm32/hda-bullseye2.qcow2,format=qcow2,id=hd \
-device virtio-blk-device,drive=hd -netdev user,id=mynet \
-device virtio-net-device,netdev=mynet \
-bios edk2-arm-code.fd \
-no-reboot
Created executable file
/opt/rasp/teardown-rasp.sh:
Code:
#!/bin/bash
echo "Tearing down rasp ..."
if [ -f /tmp/rasp-activated ]; then
rm /tmp/rasp-activated
else
echo "Doesnt seem to be up: Skipping ..."
fi
Created systemd unit file :
/etc/systemd/system/rasp.service
Code:
[Unit]
Description=Setup rasp
#After=network.target
[Service]
Type=oneshot
ExecStart=/opt/rasp/setup-rasp.sh
RemainAfterExit=true
ExecStop=/opt/foo/teardown-rasp.sh
StandardOutput=journal
[Install]
WantedBy=multi-user.target
and I have activated the service with :
sudo systemctl enable rasp.service
I have rebooted ubuntu and I saw that the nfs folder I9 has been mounted,but the raspberry qemu-system-aarch64 virtual machine didn't start because this error :
Code:
zi@zi-desktop:~$ sudo systemctl status raspberry.service

the vm starts correctly when I open a terminal and I run the qemu vm from there.
I have also tried this script :
/opt/rasp/setup-rasp.sh:
Code:
#!/bin/bash
gnome-terminal
this time error is :
Unable to init server: could not connect : connection refused failed to parse arguments: cannot open display:
