Problem using Intel integrated graphics GPU (Xorg)

I am trying to get the Intel integrated GPU working with my Parabola (Arch variant) desktop PC. According to lspci, the GPU is: 00:02.0 Display controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09) I have reconfigured my xorg.conf files to point to it; however, when I run startx, I get the following error in the Xorg log file: [ 1611.090] (II) Initializing extension GLX [ 1611.101] (EE) AIGLX error: dlopen of /usr/lib/dri/i965_dri.so failed (/usr/lib/dri/i965_dri.so: cannot open shared object file: No such file or directory) [ 1611.101] (EE) AIGLX error: unable to load driver i965 So, it seems to not be able to find the i965 driver for the GPU. Looking in /usr/lib/dri verifies that the driver file is not there: # ls /usr/lib/dri crocus_dri.so iris_dri.so nouveau_dri.so r600_dri.so swrast_dri.so vmwgfx_dri.so d3d12_dri.so kms_swrast_dri.so r300_dri.so radeonsi_dri.so virtio_gpu_dri.so zink_dri.so *However*, if I check the file list for the mesa package I have installed, it says the file should be installed: # pacman -Fl mesa | grep dri mesa usr/include/GL/internal/dri_interface.h mesa usr/lib/dri/ mesa usr/lib/dri/i915_dri.so mesa usr/lib/dri/i965_dri.so mesa usr/lib/dri/iris_dri.so mesa usr/lib/dri/kms_swrast_dri.so mesa usr/lib/dri/nouveau_dri.so mesa usr/lib/dri/nouveau_vieux_dri.so mesa usr/lib/dri/r200_dri.so mesa usr/lib/dri/r300_dri.so mesa usr/lib/dri/r600_dri.so mesa usr/lib/dri/radeon_dri.so mesa usr/lib/dri/radeonsi_dri.so mesa usr/lib/dri/swrast_dri.so mesa usr/lib/dri/virtio_gpu_dri.so mesa usr/lib/dri/vmwgfx_dri.so mesa usr/lib/pkgconfig/dri.pc mesa usr/share/drirc.d/ mesa usr/share/drirc.d/00-mesa-defaults.conf **However**, if I check the mesa package tar archive, that driver file is clearly not present: # tar -tf mesa-22.2.1-1-x86_64.pkg.tar.zst | grep dri usr/include/GL/internal/dri_interface.h usr/lib/dri/ usr/lib/dri/crocus_dri.so usr/lib/dri/d3d12_dri.so usr/lib/dri/iris_dri.so usr/lib/dri/kms_swrast_dri.so usr/lib/dri/nouveau_dri.so usr/lib/dri/r300_dri.so usr/lib/dri/r600_dri.so usr/lib/dri/radeonsi_dri.so usr/lib/dri/swrast_dri.so usr/lib/dri/virtio_gpu_dri.so usr/lib/dri/vmwgfx_dri.so usr/lib/dri/zink_dri.so usr/lib/pkgconfig/dri.pc usr/share/drirc.d/ usr/share/drirc.d/00-mesa-defaults.conf So, what's going on here then? Is 'i965_dri.so' supposed to be provided with mesa, or am I supposed to get it from somewhere else? If it is supposed to be there, I should probably file an issue report?
