Onboard

Transparency issue with compiled version

Asked by Mammnon

Hello there,

onboard is amazing, i'm using it on my touchscreen everyday. Thanks a lot for everything you did and everything you'll do.

I'm trying to create a very small environnement on CentOS with the fewest possible packages. Therefore I have to compile onboard (I leave the snippets bellow for whoever needs it).

When I use onboard in a complete KDE on Gnome environnement everything is fine, but if I use it in the smallest environnement I could, using lightdm for instance with nothing else, then the onboard transparency doesn't work.

Of course the probleme might be a missing package, but I found no helpfull log.

Could you please advise? Maybe give few keybwords or libraries names you're using and I'll try to figure this out...

Thanks a lot for your help

More details:

The problem doesn't come from onboard itself as if I install gnome afterwards it will work perfectly fine (no need to recompile) but still not with lightdm....

I'm trying to understand why it doesn't work with lightdm ...

Problem was between keyborad and chair, sorry for the post.

The problem is obviously not lightDM nor onboard

i3 as many light window manager doesn't properly take care of the transparency, there is nothing anyone can do.

Again, thanks a lot for your amazing virtual keyboard

Actually I found out the exact same problem running onboard with startx without any window manager....
