I am not be able to find the correct video driver for my raspberry pi 3B.
I am using archlinux.
I was able to make the video output 1080p by adding these lines to my config.txt file.

Code: Select all

hdml_mode=16
disable_overscan=1

However my screen still glitches/lags when browsing the internet via chromium.

I have tried to use this https://wiki.archlinux.org/index.php/xo ... ay_manager to install driver manually.
However this error message keeps popping up:

Code: Select all

pcilib:Cannot open /proc/bus/pci
lspci: Cannot find any working access method

What am I gonna do now?

The graphics issue is true, I can confirm that. When I tried Arch Linux ARM, the instructions were to install xf86-video-fbdev or xf86-video-fbturbo for Xorg graphics driver. But still after installing the drivers, the graphics output is poor, as he said, full of glitches. It can be encountered when dragging a terminal or file manager window.
One thing also to mention that without this driver, you can't even start an Xorg session. I've already tried my best but still no hope finding a solution.

You will need to approach the Developrs if their software has issues !!
