[neonix]

I tried two options. One with fbdev-Xorg.conf.tcz and another with Xorg -reconfigure.

Hi neonix
I clicked on your YouTube link expecting to see a video
relating to the problem you are experiencing. Instead, I
was greeted with a video promoting xlibre.

Did you accidentally post the wrong link?

[Rich]

Hi neonix

I tried two options. One with fbdev-Xorg.conf.tcz and another with Xorg -reconfigure. ...

Where did you get that from?

It should be:

Code: [Select]

sudo su
Xorg -configure
mv /root/xorg.conf.new /home/tc/xorg.conf
chmod 666 /home/tc/xorg.conf
chown tc:staff /home/tc/xorg.conf
exitThen you need to copy the  xorg.conf  file where Xorg can find it.

[Rich]

Hi neonix
According to this:

...

Code: [Select]

----- Snip -----
[  1212.334] (EE) Device(s) detected, but none match those in the config file.
 ----- Snip ----- ...

Xorg thinks you have a config file specifying devices it can't use.

I also noticed this, which may or may not be an issue:

Code: [Select]

X.Org X Server 1.21.1.16
 ----- Snip -----
[  1212.316] (II) Module fbdev: vendor="X.Org Foundation"
[  1212.316] compiled for 1.21.1.3, module version = 0.5.0
 ----- Snip -----

The  "compiled for"  version number does not match the
"X.Org X Server"  version number. The versions for the
other modules do match.

Hi neonix

No, I just realized that quality of code in Xorg is bad, since maybe 2018. Xorg could go in autoconfiguration path or manual configuration path. New users don't know how to configure it properly, It should be easy to configure.

[Juanito]

..and to add to the fun I just read they’re having to revert a bunch of xorg-server commits after they released a developer.

[Juanito]

The  "compiled for"  version number does not match the
"X.Org X Server"  version number. The versions for the
other modules do match.

I think that as long as the major version matches, i.e. 1.21 in this case, then it's OK.
