i have gotten it to work previously but then i had issues with sddm only when the ddriver was installed, but had the gpu working when it was. Currently i am using plasma-login-manager and thought it finaly worked when i got a login screen even after installing the driver but no its using the igpu still.

glxinfo outputs this :

[sam@yourhostname ~]$ glxinfo | grep NVIDIA
[sam@yourhostname ~]$ glxinfo | grep INTEL
    GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_INTEL_swap_event, 
    GL_INTEL_blackhole_render, GL_INTEL_conservative_rasterization, 
    GL_INTEL_performance_query, GL_INTEL_shader_atomic_float_minmax, 
    GL_INTEL_shader_integer_functions2, GL_KHR_blend_equation_advanced, 
    GL_INTEL_blackhole_render, GL_INTEL_performance_query, 
    GL_INTEL_shader_atomic_float_minmax, GL_INTEL_shader_integer_functions2, 
    GL_EXT_texture_view, GL_EXT_unpack_subimage, GL_INTEL_blackhole_render, 
    GL_INTEL_conservative_rasterization, GL_INTEL_performance_query,

modeset is y too
Since i am using wayland, the NVIDIA_Optimus page isnt very rtfm compatible

glxinfo doesn't help much for wayland,

$ eglinfo -B
$ DRI_PRIME=1 eglinfo -B

may be useful .

Are you running KDE plasma 6 or another wayland compositor/DE ?

To use nvidia with blender you'll need to install & configure cuda, see https://wiki.archlinux.org/title/Genera … units#CUDA .
