I am using Ubuntu 14.04 (previously linux kernel 4.2).Today I got a security update message and allowed it and now my linux kernel version is 4.4 and when I opened Details option from settings,it shows graphics device to be "Gallium 0.4 on llvmpipe (LLVM 3.8, 128 bits)".I read about it and saw many bad reviews.Then I played a movie using VLC and performance seemed a lot laggy.

What should I do now?

  • I fixed it by booting with kernel 4.2 from grub and then followed http://askubuntu.com/questions/595359/fglrx-wont-install-unable-to-correct-problems-you-have-held-broken-packages and then removed linux-image-lts-xenial and reinstalled linux-image-lts-wily – Hasanur Rashid Aug 25 '16 at 20:17

After I got the message of the eol of the hardware enablement, I updated via software updater and ended up with Linux 4.4 and a non-working graphics system. To boot, I had to go via recovery and got the software driver without acceleration (llvmpipe). There seems to be no driver available that can work with this kernel. I solved it by installing a 4.5.3 kernel from "http://kernel.ubuntu.com/~kernel-ppa/mainline/". I now am using the open-source drivers, graphics is shown as "Gallium 0.4 on AMD ARUBA (DRM 2.43.0, LLVM 3.8.0)"
