Ubuntu – Graphics driver being reported as Gallium 0.4 on llvmpipe (LLVM 0x300) instead of intel

intel graphics

I have an integrated Intel 945GM in a Toshiba laptop. Previously the graphics driver was reported correctly, but at some point it has changed. I've noticed general poor performance and though it should meet minimum requirements for unity 3d is using unity 2d. Under the details panel in system settings it is now reporting Gallium 0.4 on llvmpipe (LLVM 0x300). any help would be appreciated. I have searched google for hours trying to find an answer.

  • I had to edit xorg.conf in order to get this to work. I had tried the instructions to create a xorg.conf file for 12.04 with no luck, giving me a "could not create lock file in /tmp/.tXO -lock" error. Running man xorg.conf it gave me several alternate locations to find it. Hidden among the depths of the system in /etc/X11/ was xorg.conf. I had to change the driver to "intel" and the description in my case "Intel 945gm". I then ran sudo -i gedit to edit the file to my needs. After a restart the correct driver is now in use. Hope this can help someone else. :)
