How to switch Xorg to llvmpipe
Hello! I have a very old PC with intel i915 graphics, which doesn't correctly display KDE and shows a lot of bugs. I know it is possible to switch to software acceleration in X server. On NVdia I can pass nouveau.noaccel=1 to kernel. So how can I disable hardware acceleration here? Maybe this is possible via Xorg config?
Here. Option GLX.
Llvmpipe is enabled in mesa at compilation time and actually modifies the swrast_*.so the last time I checked. Not runtime configurable. Also, I know at one point it had issues running on 32 bit machines. Not sure if that's still the case.
maybe this can help you
I think this is for applications not for graphical server
idk, but i would try switching of DRM/DRI (Direct Rendering Manager/Direct Rendering Interface). it's X hardware rendering.
