Change brightness #36

Closed Rootinator closed 2 years ago

Rootinator commented 5 years ago

Hello,

how can I change the brightness without SSH?

viktorgino commented 5 years ago

There isn't really a way yet. What screen are you using?

Rootinator commented 5 years ago

I use the official touchscreen for Raspberry Pi

gregd72002 commented 5 years ago

@Rootinator , we are working to have it implemented in the next release. Meantime it is already working in this fork: https://github.com/gregd72002/headunit-desktop

Rootinator commented 5 years ago

How can I add the new feature to an existing system without having to reinstall the whole system?

gregd72002 commented 5 years ago

The brightness plugin requires some extra functionality that was not present in previous version on headunit-desktop. As such update to headunit-desktop is needed. @viktorgino might have more information on the build process

viktorgino commented 5 years ago

@gregd72002 it is built by pi-ge, headunit is built here : https://github.com/viktorgino/pi-gen/blob/master/stage4/01-install-headunit/00-run.sh

Rootinator commented 5 years ago

How should I proceed?

I open an SSH session and call the file or do I need to install a fresh Debian and create the file?

viktorgino commented 5 years ago

@Rootinator no need to reinstall, if you cd to /opt/headunit-desktop then pull the latest from the git remote : git pull --recurse-submodules and run qmake CONFIG+=rpi -config release then make -j2 this should rebuild it, then restart the pi and you should have the latest headunit installed

Rootinator commented 5 years ago

When I execute these commands and then restart the Raspberry (sudo reboot now), the headunit window will not boot.

He shows the picture with the speedometer with "Viktorgino's Headunit Desktop". After that comes nothing after many minutes.

@Rootinator what's the output of journalctl -u headunit -b?

Rootinator commented 5 years ago

This is the result of "journalctl -u headunit -b":

@Rootinator can you try to find the libdefault-theme.so file? Need to know if its missing or just located elsewhere.

Rootinator commented 5 years ago

The file "libdefault-theme.so" was not found.

find: 'libdefault-theme.so': No such file or directory

Rootinator commented 5 years ago

Is there anything new about this topic?

gregd72002 commented 5 years ago

You can try using the image. Not promising it is going to resolve all your problems but the brightness should work. It is experimental though!

Rootinator commented 5 years ago

Thanks a lot for this!

But I really do not want to use a completely new image because I have personalized my current system (equalizer, external soundcard as standard, ...)

Otherwise there is no way to update the headunit without having to reconfigure everything?

viktorgino commented 5 years ago

@Rootinator I can build headunit and send it to you, my plan is to build have it built automatically when a new tag is added in this repo and shared to my apt repository. Will get around to do that eventually, but been tied down with navit and other stuff
