Hello,
I encountered this problem several times now: After installing the panfrost GPU drivers
sudo add-apt-repository ppa:liujianfeng1994/panfork-mesa
sudo add-apt-repository ppa:liujianfeng1994/rockchip-multimedia
After reboot there is a black screen with a blinking cursor. This happened with the Debian image, the RebornOS image and the Armbian image. Android doesn’t work at all.
Has anybody experienced similar problems and knows how to fix it?
