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.
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?
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?
