LENOVO TAB M10 HD GEN2 - GPU drivers not present

OOKAMI

hello

first of all, i would like to say thaniks about this solution and have now a tablet wokring with Linux

installation has been easy and fully working but i noticed gpu are not fully working on this model

indeed, after some researchs, i found way to install INXI by using terminal command line

sudo mount -o remount,rw /
sudo apt install inxi

when used command line

inxi -b

result show gpu using X11 generic and LLVMPIPE
also tested with firefox and confirmed no hardware acceleration

i tried to find where i can download GPU drivers and perform installation without success

maybe someone have a solution to share and make tablet more powerfull ?

many thanks for your help and support

Hi @OOKAMI

This kind of tinkering is not really supported on Ubuntu Touch.
But if you have enough knowledge to know what you're doing (it seems like it), I would advise to have a look at the porting documentation.

Because, as you well realized, Ubuntu Touch is not a regular Debian based distribution on a PC.
We use an immutable image and not every tool that you're used to are available.
Supporting hardware acceleration is something made possible during the making of a port, so if you're interested, I suggest you familiarize yourself with the porting documentation which will give you pointers and ways to get some help.

Here is the main gate to knowledge https://docs.ubports.com/en/latest/porting/introduction/Intro.html

@OOKAMI Actually hardware acceleration works. You can confirm that by checking if the default media player can play videos.

Inxi shows wrong output because the libraries it uses cannot use the intefaces exposed by Halium. It shows X11 while it is Mir, and opengl doesn't use the right driver by default. Try glxgears with different driver. I remember es2 to work.
