Arch headless Boinc server [Solved]

Clean fresh default install (pactrap /mnt base grub)
Then intalled
xorg-server xorg-xinit xorg-server-utils
nvidia
openssh
boinc-nox and openclnvidia

and add remote_hosts.cfg to get remotly gui connection work.

But boinc, no usable Gpus found.

Ssh remotly login root, startx and restart boinc
Cuda gpu capatilies work

Proplem is.

How auto star xserver, without login, no DE, no windows manager, no display manager.

Wait...boinc-nox?  Don't you want just regular boinc if you are using X?
You could ... run boinc in a

DISPLAY=:xx boinc

maybe or by using xpra-winswitch in the AUR?  Then you could remotely connect to the active process that way.  Using xpra-winswitch is kinda silly isn't it?  All that intense graphics over the network, when all you need to do to check process can be done just like it is done in boinc-nox.

Re: Arch headless Boinc server [Solved]

Do you have cuda installed?
What does your /var/lib/boinc/std*.txt show in regards to cuda?

Re: Arch headless Boinc server [Solved]

I'm thinking it's the xorg-server-xephyr, xorg-server-xnest or xorg-server-xvfb server that can run without being displayed.

Working
It not necessary start X

And new problems, how start shell scripts in systemd.

#!/bin/bash
 
/sbin/modprobe nvidia
 
if [ "$?" -eq 0 ]; then
 
# Count the number of NVIDIA controllers found.
 
N3D=`lspci | grep -i NVIDIA | grep "3D controller" | wc -l`
 
NVGA=`lspci | grep -i NVIDIA | grep "VGA compatible controller" | wc -l`
 
N=`expr $N3D + $NVGA - 1`
 
for i in `seq 0 $N`; do
mknod -m 666 /dev/nvidia$i c 195 $i
done
 
mknod -m 666 /dev/nvidiactl c 195 255
else
exit 1
fi

Your modprobe that the kernel should activate automatically should make the devices for you.
This is a sysvinit script, not a systemd script.  Although all it takes is for the systemd script to call your script.

Re: Arch headless Boinc server [Solved]

Shell scripts directly run (sh /usr/bin/boinc-cuda) works.

But systemd not

[Unit]
Description=My script

[Service]
ExecStart=/usr/bin/boinc-cuda

[Install]
WantedBy=multi-user.target

Failed to issue method call: Unit boinc-cuda.service failed to load: No such file or directory. See system logs and 'systemctl status boinc-cuda.service' for details.

Re: Arch headless Boinc server [Solved]

Solved

I renamed boinc-cuda to boinc-cuda.service
and working systemd scripts is

[Unit]
Description=boinc-cuda
Before=boinc.service

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/boinc-cuda

[Install]
WantedBy=boinc.service

Now i have  "Arch headless Boinc server"
