Archlinux on Raspberry Pi 3 GPU driver?

[mrchow19910319]

I have been trying to install a gnu driver on my raspberry pi.

In the Xorg wiki (https://wiki.archlinux.org/index.php/xorg#Driver_installation), it says to identify your card you need to type in 

$ lspci | grep -e VGA -e 3D

I did and my terminal tells me that 

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

Is there any fix to this? 

Or just install another driver? 

 

@noahdvs You were right when you asked me before, I did not install proper driver for my arch linux system.

Here's a screenshot too: 

I think I did installed a driver for it, but , the display is still stuck at 640x480.

Try changing video related settings in /boot/config.txt such as disable_overscan.

I've added these line to my config.txt file: 

 

• hdmi_mode=16    #this made my screen resolution 1080p.
• disable_overscan=1  #this made the black bars went away

However, the screen still flickers when scrolling in the browser. I think I installed the wrong driver. And I don't know which one I should install.

Hmm... this Arch Wiki page says:

X.org driver

The X.org driver for Raspberry Pi can be installed with the xf86-video-fbdev or xf86-video-fbturbo-git package.

You seem to already have the xf86-video-fbdev package installed, so perhaps you should install the xf86-video-fbturbo-git package. It's probably a package on the AUR. If it's not available in the AUR or the official repositories, you can build it from source.

GitHub page: https://github.com/ssvb/xf86-video-fbturbo

Installation: https://github.com/ssvb/xf86-video-fbturbo/wiki/Installation

Those installation instructions are Debian/Raspbian oriented, but adapting them for Arch should just be a matter of finding the equivalent Arch blackages to install.
