I strongly recommend Settle GPU driver first if you are using dual GPU and one of them is Nvidia. Because one of my systems can’t be open again after following a set of processes for installing an Nvidia driver. As it said by Linus Torvalds: F**K YOU, NVIDIA! After you switched to the Nvidia driver, your OBS could work fluently.
This post from linuxconfig could help you install driver appropriately.
The trick is you need to switch into an old kernel (exp: 5.4.116). I even failed to install it on kernel 5.4.106_rt54-1.

The problem of building fail for opencv is the SDK tool was changes. But we could settle our own sdk too by setting android.sdk_path= in buildozer file.
