Archlinux video driver issue.

Fri Sep 15, 2017 3:37 pm

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?

Arch Linux Arm have a Raspberry Pi dedicated web page:

Glitches and slow downs are nothing to do with the video output size- that's just Chromium being a bit slow. If the display is 1080p, the display is 1080p.

I suspect that the instructions you are following are not for the Pi.

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 !!

Indeed. We (RPF(T)) don't support Arch here, we support Raspbian. Does that work OK?
