NanoPi M1 + Xorg

Postby bamboo » Wed Apr 24, 2024 9:35 pm

Hello,

I am aware that I am totally on the unsupported side and that the device is old, so I kindly ask for help.

I tried to follow this guide [url]https://wiki.archlinux.org/title/User:Lafleur/NanoPi_M1[/url] and I got working Arch instalation ... until I tried to run GUI.

Can somebody point me a direction how to debug Xorg log:

[code]
# startx

(EE)
(EE) Backtrace:
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error
[/code]

That's not a mistake - the log looks literally like this. No X.conf present. It should use Lima driver (checked lsmod and it is loaded). Well but all I know is that an exception occured. No message, no backtrace. It producers the same log when I try to start LightDM.

[code]
# dmesg | grep lima

To isolate the driver as the source of your problem, first try launching X without the Mali GPU. That is, uninstall the driver and see if X works with xf86-video-fbdev[1] or KMS[2].
