I recently switched from Mate-Desktop (Ubuntu Mate) to KDE Plasma including Bismuth as tiling Window Manager. Tiling is really a new concept to me and I really have to get used to it. But I do like it so far. But... from time to time my KDE Taskbar is disappearing after coming back from hibernate mode. Long story short:
* Open a terminal (CTRL+ALT+T)
* call 'screen' to keep the command alive even you close the terminal
* plasmashell --replace
* close the terminalBlupp

Server update
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.
