How to switch from NVIDIA to Nouveau / no OpenGL

Hi,

I am very new with this.
My issue: I wanted to switch from NVIDIA to Nouveau. I have laptop Dell XPS M1530 with GeForce 8600M GT, using linux-lts.
I uninstalled nvidia drivers, installed nouveau with mesa, glu, lib32-mesa-, mesa-demos, mesa-vdpau. And I have no OpenGL.
Xorg starts normally (startx) without issues...

glxinfo gives such feedback:

name of display: :0
X Error of failed request:  BadValue (integer parameter out of range for operation)
Major opcode of failed request:  154 (GLX)
Minor opcode of failed request:  24 (X_GLXCreateNewContext)
Value in failed request:  0x0
Serial number of failed request:  37
Current serial number in output stream:  38

I don't know what the problem is. Please, help.

There is nothing to install to switch to nouveau other than uninstalling NVIDIA blobs. If you happened to install xf86-video-nouveau, then this could be your problem and you should remove any xf86-video-*. Nouveau works best with modesetting driver. Legacy DDX drivers are mostly obsolete.

Nouveau works great with Wayland, too.

How did you uninstall nvidia? pacman -R nvidia is not guaranteed to also pick up the nvidia-utils packages which you need to remove as well (since the kernel driver package is not necessarily tied to the userspace libs)
