No GUI after install xf86-video-nouveau

samidon · Aug 18, 2020

Hello there again!
I played a little with KaOS since last weeks. Everything worked perfectly until today. I wanted to finally take a closer look to graphic driver because "glxinfo | grep OpenGL" always showed "render: llvmpipe". I used nvidia-390xx driver (latest version). So i read: https://kaosx.us/docs/nvidia/ and i decided to try "xf86-video-nouveau". I uninstalled nvidia and install nouveau. When i reboot system ... nothing happened. No GUI - only some letters and flashing "| ". The only thing i could do is to get access to root - when i did - i uninstalled nouveau (hoped it bring back GUI) - but it didnt help.
The only thing that could work - for sure - is install nvidia-390xx again but in terminal i dont have access to Wi-Fi.
Any ideas if there is rescue of that? I know @demm that u said once (cause 1 persion here also have trouble with rendering graphic using no GPU) - that this is issue with not driver but it is some kind of bug?

Pacman log needed to see what you did.
If you already installed 390xx before, re-installing does not need internet, the packages are in your /var/cache/pacman/pkg directory, you can just pacman -U from there.

demm Uf.. Thank you!! That worked. I just didn't know where drivers are stored. So i know that nouveau is not for me. I returned to nvidia and it worked fine and smooth. However as You see below - OpenGL renders from llvmpipe instead of GeForce Gt630. This cause problem on Steam - I've succesfully installed CS:GO, but because of that it's unplayable - fps is about 5-10. Now the qeustion is - is there something i can do with that? I mean - is there a way to change llvmpipe into GeForce Gt630?

Again, post the pacman log, the free drivers will of course result in a usable desktop (even nouveau isn't needed, kernel included modesetting works very good).

So many entries for removing and installing nvidia packages....
So what do you actually have installed for nvidia now?
pacman -Qs nvidia

Also, tons of entries for things completely foreign to KaOS, looks like your install is no longer actually KaOS (supported). One last warning, using packages/repos not from KaOS will break your install, and will result in posts automatically removed from this forum.
So what is the output of pacman -Qm ?

And regarding free/nouveau, are you runnning an X session or using Wayland, latter will not work with free.

pacman -Qs nvidia

pacman -Qm - nothing showed up

"things completely foreign to KaOS" - for the future - can U give me an example? I do want to be part of this community so i don't want to make some troubles. As for my "defense" - sometimes i was looking for some programs i used to had either on Windows or in previous Linux which had KDE (thats why i'm having some bad habits because no-one never told me i'm doing something wrong - using bad repositories/ packages - before). I'm sorry for that.

"And regarding free/nouveau, are you runnning an X session or using Wayland, latter will not work with free." - I do not know if in things foreign to KaOS are commands so to be more carefull i will write only, that terminal showed me "X11".
/Thank You for Your help and time and again Im sorry for doing bad thins to KaOS (not intentionally)

samidon "things completely foreign to KaOS" - for the future - can U give me an example?

From the pacman log (just a few from the very many), trying to install/installing packages not part of KaOS:

[2020-08-16T08:33:31+0200] [PACMAN] Running 'pacman -Sy rtl88x2bu-dkms'

There are many ways to search what is in the KaOS repositories, search function in Octopi, using pacman -Ss, or use the online package viewer.
Good to see pacman -Qm comes up empty, that means you were not successful in installing packages not from KaOS.

But this all leaves no answer why free does not boot in this system, nor does it explain why llvmpipe is used instead of opengl.
Would it be possible to use the July KaOS ISO and boot into live mode one more time, this time making sure to select non-free in the live bootloader? Then in live mode get the output of inxi -Gx and post that result here.
