Program not running after installation #36

Closed mattiasJohnson closed 2 years ago

mattiasJohnson commented 2 years ago

I am running ubuntu 20.04 with i3wm and my computer is Lenovo Legion 7 and after following through the installation (that I've done on other computers before so believe I've done my part correctly) there is no touchcursor.service. Sorry for the wall of text wasn't sure what data was relevant so included most of it.

Installation :heavy_check_mark:

From what I've understood I have successfully installed touchcursor. I cloned it directly and in touchcursor-linux/src/key.c comment out the four lines mentioned in https://github.com/donniebreve/touchcursor-linux/issues/35 and then preceded with

$ make
gcc -g -Wall -c src/keys.c -o obj/keys.o
gcc -g -Wall -c src/queue.c -o obj/queue.o
gcc -g -Wall -c src/emit.c -o obj/emit.o
gcc -g -Wall -c src/config.c -o obj/config.o
gcc -g -Wall -c src/binding.c -o obj/binding.o

$ make install
# Stopping the service
systemctl --user stop touchcursor.service

# Copying application to /usr/bin
# This action requires sudo.
sudo cp ./out/touchcursor /usr/bin
sudo chmod u+s /usr/bin/touchcursor

# Copying default configuration file to /home/mattias/.config/touchcursor/touchcursor.conf
mkdir -p /home/mattias/.config/touchcursor
cp -n touchcursor.conf /home/mattias/.config/touchcursor

# Copying service file to /home/mattias/.config/systemd/user
mkdir -p /home/mattias/.config/systemd/user
cp -f touchcursor.service /home/mattias/.config/systemd/user

# Enabling and starting the service
systemctl --user daemon-reload
systemctl --user enable touchcursor.service
systemctl --user start touchcursor.service

Updating config :heavy_check_mark:

I'm changing config Name line to Name="AT Translated Set 2 keyboard" since I get the following output:

$ cat /proc/bus/input/devices | less

No touchcursor.service :x:

systemctl list-units --type=service --allboth before and after touchcursor.service restart does not include touchcursor.service.

Testing running the binary :x:

Running binary in touchcursor-linux/out/touchcursor :x:

My guess is that trying this binary is unnecessary since it's not the one being run by the service but anyhow:

$ ./touchcursor

I'm not enlightened enough about how systemctl works, I believe the service is running. I saw a similar issue https://github.com/donniebreve/touchcursor-linux/issues/33 and here's the output of the two commands the guy in that thread was asked to run

$ systemctl --user start touchcursor.service
$ systemctl --user status touchcursor.service

And here are the lines follwing Started Touch Cursor Service from the systemctl --user restart touchcursor.service; sleep 5; journalctl -e command

Hey @mattiasJohnson

No service

Make sure you run systemctl --user list-units --type=service --all

Systemctl has two spaces, system services and user services. Most services run in the system wide group (systemctl ...) but touchcursor-linux runs in the user group (systemctl --user ...)

Running binary in touchcursor-linux/out/touchcursor

touchcursor-linux requires elevated access, so when it installs the application to /usr/bin, the file owner is root and the install script sets the sticky bit.

These errors tell the story:

error: cannot open the input device, is this file set to the 'input' group or equivalent?: Permission denied. error: could not capture the keyboard device

Looks like I need to update that error message though, I moved away from using the input group.

If you want to run the touchcursor-linx/out/touchcursor application, you have to run it with sudo. Unfortunately running it with sudo will have the application think it is running as root, and it will look for the configuration file at /etc/touchcursor/touchcursor.conf

See https://www.redhat.com/sysadmin/suid-sgid-sticky-bit (user + s (pecial)) for more information.

Running binary in /usr/bin/touchcursor

This error is telling you the device has already been captured by something:

error: EVIOCGRAB: Device or resource busy.

Try first running systemctl --user stop touchcursor, then run /usr/bin/touchcursor to see the output from the application.
