Lately I experienced problems using alt+tab for switching between applications in manjaro-linux using mate-desktop. The problem seems to be the little thumbsnails showing a current preview of the specific application.
To get rid of the problem:
Pererences > WindowsUncheck 'Enable software compositing window manager'

Having problems starting ubuntu-linux looking like this? To make the long story short: * Grub > Advanced Options > Pick the latest kernel in rescue mode * In the rescue-menu: * 1) network * 2) root > login to your root account apt remove --purge nvidia-* ubuntu-drivers autoinstall That solved it for me.
