I see many graphical artifacts in using Ubuntu 14.04 on Macbook Air 2013-mid. Doing CTRL-Super-[key] causes often a time-lag and sluttering of the graphics (bad sign of the drivers). There are also other complications of the drivers such as much loading (3-7 seconds) of some basic movements such as moving the window by the former keybinding. Loading does not affect all the time but often (about 1/7).

  • 4th generation Intel Core i5 processor with Intel HD graphics 5000
  • I just have the defaults in my system: 3rd party packages allowed.

Ubuntu 14.04

I tried Mark's proposed thread and its code found here about Intel graphic drivers for Ubuntu 14.04

sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libqt5gui5 libgles1-mesa-lts-utopic libgles2-mesa-lts-utopic libgl1-mesa-glx-lts-utopic libgl1-mesa-glx-lts-utopic:i386 libglapi-mesa-lts-utopic:i386 libegl1-mesa-drivers-lts-utopic

Output: many things broke: keyboard-layout changed to Qwerty, gpointing-device-settings stopped working, ... I would like to understand why. Why those drivers cause such complications? Are they just temporary? Should I continue with those drivers?

I do sudo apt-get update, sudo apt-get upgrade and sudo apt-get autoremove but the problems are not resolved back to default configurations.

To recover from the damage

How can you uninstall those packages and return to the earlier state? I do not understand what the system did so I want to the earlier configuration.

  • many reinstall cycles and fixing packages individually until better state reached

How can you have better GPU drivers in Ubuntu 14.04 and/or 16.04 on Macbook?

    On intels website are installers but 14.04 seems not to be supported 01.org/linuxgraphics/downloads I don't know why because both 14.10 and 15.04 are, I don't know what else to suggest. In additional drivers, can you activate the microcode driver? It is for Intel CPU but may help a little with this kind of GPU. – Mark Kirby May 30 '16 at 16:23

    sudo apt-get purge linux-generic-lts-utopic xserver-xorg-lts-utopic libqt5gui5 libgles1-mesa-lts-utopic libgles2-mesa-lts-utopic libgl1-mesa-glx-lts-utopic libgl1-mesa-glx-lts-utopic:i386 libglapi-mesa-lts-utopic:i386 libegl1-mesa-drivers-lts-utopic I guess but not sure – Mark Kirby May 30 '16 at 16:42

    Using the 15.10 installer from the intel link 01.org/linuxgraphics/downloads combined with this allanbogh.com/2016/01/05/… should let you install it with the installer. I have not tried it but it seems sound to me. – Mark Kirby Jun 6 '16 at 12:45

MarkKirby's proposal in Ubuntu 14.04

sudo apt-get purge linux-generic-lts-utopic xserver-xorg-lts-utopic libqt5gui5 libgles1-mesa-lts-utopic libgles2-mesa-lts-utopic libgl1-mesa-glx-lts-utopic libgl1-mesa-glx-lts-utopic:i386 libglapi-mesa-lts-utopic:i386 libegl1-mesa-drivers-lts-utopic

Attempt in Ubuntu 16.04 where I did not manage to get anything else work

sudo apt-get purge linux-generic-lts-utopic 

His proposal about 15.10 drivers in 16.04 described here.
