GeForce RTX 2060 Mobile vs. Gentoo 5.1.15

Hello

I would like to ask you for help getting X to work on my Gentoo system. After a fresh install I cannot get X to work. “startx” produces the error:

I’m new here and I could not figure out how to attach the nvidia-bug-report.log.gz (the message above is an extract).
I’m not sure it is a problem with the nvidia drivers. “modprobe nvidia” works. Adding the “-- -logverbose 6” argument to startx does not produce extra information, at least not onto the console.

Any hint will be very helpful to me. Thank you very much in advance!

Kind regards.

Rather looks like a malformed xorg.conf than a driver problem.
Please run nvidia-bug-report.sh as root and attach the resulting .gz file to your post. Hovering the mouse over an existing post of yours will reveal a paperclip icon.

Hello

I also think that the driver does not play a role here (it does not get even mentioned in the error message).
I read the chaper 6 of the docs, regarding xorg.conf, and even experimented with a “Module” section, but nothing changed. I installed the drivers as explained in https://wiki.gentoo.org/wiki/NVIDIA/nvidia-drivers .
I attached the .gz file with the log, in my previous post. I’ll be grateful if you can pay a look at it.

Thanks a lot.
Kind regards.

Please delete
/etc/X11/xorg.conf.d/nvidia.conf
it contains

SecStion "Device"

typo.
You can also delete your xorg.conf since you only have one gpu and no special settings.

Hi

that was sharp. And it worked (I needed the xorg.con file to avoid the “no screens found” error, though).

Thank you very much for the help, particularly because the problem was something not related to your product.

Kind regards.
