After upgrading Mesa to 20.0.4, the driver for my Intel GPU (Sandy Bridge, i3-2310, HD 3000) is gone, and I only get software rendering. Reproducible: Always Steps to Reproduce: 1. Start an OpenGL application, such as glxgears Actual Results: Application shows the following error messages libGL error: MESA-LOADER: failed to open i965 (search paths /usr/lib64/dri) libGL error: failed to load driver: i965 and runs slowly with software rendering. Expected Results: Fast, hardware OpenGL rendering I notice that the file /usr/lib64/dri/i965_dri.so is missing, instead I have /usr/lib64/dri/i915_dri.so. Mesa has worked mostly as expected up to and including version 20.0.3. I have also tested both xf86-video-intel and the Xorg modesetting driver, with no change to Mesa behaviour.
Please include 'emerge --info media-libs/mesa'
Did you also update to libdrm-2.4.101 at the same time you updated to mesa-20.0.4? Can you give a build log of Mesa? Also the output of `qlist mesa`.
Well, this is interesting. I reinstalled mesa-20.0.4 for more debugging and now it works fine, the i965 driver is there. I suspect that the i915 version came from a different machine. I use a shared /usr/portage for multiple machines and the xpak format for saving binary packages with different USE flags. Still, Portage should not install binaries with the wrong USE. I share most of my binary packages between machines, but Portage usually compiles them again if I need a different USE set (mostly due to different hardware). So I apologise for any trouble, this one can be closed. Though I guess another one is in order about Portage...
