I'm trying to get a clean installation of Raspian Stretch with hardware acceleration.
Starting from latest release of Raspbian LITE, I updated everything (apt-get update, dist-upgrade etc.).
I installed Xorg Display Server and Xinit
Code: Select all
sudo apt-get install --no-install-recommends xserver-xorg xinit...then Raspbian Desktop (RPD)
Code: Select all
sudo apt-get install raspberrypi-ui-mods... the experimental OpenGL driver
Code: Select all
sudo apt-get install xcompmgr libgl1-mesa-dri...but when I activate OpenGL driver in raspi-config, I get very low performance on glxgears, as if driver it's not activated (or however as if it's much much slower than default Raspbian image available for download).
So it's seems that something is missing... any help?
THANKS
MORE DETAILS:
- memory split is set to 128Mb
- firmware is updated via rpi-update
- I launched apt-get update / upgrade also after the OpenGL driver activation
- color (or "shading") of glxgears is strangely different than that in the default Raspbian (non-Lite) ISO publicly available
- after compiling chocolate-doom (V3 with SDL2-dev etc.) in both contexts, I get 60fps on default Raspbian (non-Lite) ISO and 1 (one!) FPS on custom Raspbian Lite + RPD + OpenGL driver.
