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?

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
