Why is compositor not enabled by default?

Sat Oct 19, 2019 6:24 pm

Guake terminal, some on-screen keyboards, Sonic Pi v3.2, Chromium, Conky (I think), wbar, plank, and other applications use transparency.

And transparency requires a compositor. But Raspbian does not auto-start a compositor by default. Does anyone know why not?

BTW: I use xcompmgr. After installing, run this to make it run on boot:

Code: Select all

echo "@xcompmgr -C -c -o 0.5 -l -19 -t -10 -r 14 -f -O 0.05 -I 0.05" >> /home/pi/.config/lxsession/LXDE-pi/autostart
Edit: Turns out xcompmgr ships with Raspbian, but is disabled by default. Title now makes that clear.

My doctor told me my brain is as useful as a Raspberry Pi. Is that a compliment?

Not sure what you are using, but on latest Raspbian it IS installed by default and can be enabled via the "Advanced Options" menu in raspi-config.

I would guess it's not enabled by default because because either
most people don't need it
the same job is done by something else in the GPU.
