How to get rid of the Gallium 0.4 on llvmpipe (LLVM 0x300) driver? INTEL needed

Question

Ubuntu 12.04 LTS only runs 2D mode after changing MB and CPU. It appears using the wrong video driver: "Gallium 0.4 on llvmpipe (LLVM 0x300)" rather than the required "Intel" G43 version from the "xserver-xorg-video-intel" driver package. The new motherboard is a MSI Z87-G43 with a i7 CPU.

I tried lots of things and checked out about all I could find on the web. I removed the VMware drivers, nvidia en ATI divers and their configuration files without result. Creating an etc/X11/xorg.conf file with "intel" assigned to be used, the system became instable. I even did a fresh Ubuntu 12.04 install on an old HD, finding out that the meant "Intel" driver appeared to be used!

Now I'm stuck!

What should I do to get it right for my existing Ubuntu 12.04 LTS system?

Solution

The xserver-xorg-video-intel package provides the basic Xorg driver which is used for 2D drawing, etc. llvmpipe is the software renderer for 3D operations, if you install the libgl1-mesa-dri package, then you should have the Mesa DRI Intel(r) ... renderer.

Note that the original drivers shipped with 12.04 are quite old, you are suggested to install the LTS Enablement Stack to get more recent versions for the graphics subsystem and kernel.

I have checked out that the "libgl1-mesa-dri" package is installed. I also tried later versions of the xserver-xorg-video-intel package, without success. I looked in the file "/var/log/Xorg.0.log" to find that the intel module was unloaded, moving on with VESA... No idea!

@JGMS Perhaps you could paste your post your Xorg.0.log on paste.ubuntu.com? It may contain a hint. Please add the output of lsmod to your question as well, and if you want to post another log, run dmesg > dmesg.txt and post the contents of it.

That was truly a great hint! It solved the problem. Many thanks indeed!

@JGMS It would be nice if you could post the solution to your question here and mark it as accepted.

[ACCEPTED ANSWER. PROBLEM SOLVED] Getting "Intel Haswell" instead of the "Gallium 0.4 llvmpipe" video driver: I very much appreciate the support I got from an export user of Ask Ubuntu. The problem was indeed solved by loading the "LTS Enablement Stack" drivers. I Just followed the link offered by Lekensteyn and copied the commands in the terminal. Amazing how simple things can turn out to be in Ubuntu: I love it! JGMS
