 ===== Problems =====
+==== Linux Mint 19 (Ubuntu 18.04) ====
+After the upgrade from Mint 18.3 to 19, the monitor isn't working any more. The screen stays black after the ASUS logo appeared. An the Cinnamon desktop doesn't respond any more. The mouse cursor works, but nothing is clickable any more. No solutions found so far.
+=== Workaround 2 hilft: Use older intel driver as a fallback ===
+Der beschriebene Workaround Nr. 2 in (( [[https://support.displaylink.com/knowledgebase/articles/1181623-displaylink-ubuntu-driver-after-recent-x-upgrades]] )) hilft, yey!
+<code>
+Another workaround that has been proven to help on most Ubuntu 17.04
+systems and some late 16.04 updates is to use the "intel" driver for
+the integrated GPU instead of "modesetting", which is now the default.
+To do this, as a root user create a file 20-displaylink.conf under:
+/usr/share/X11/xorg.conf.d/
+with following content:
+Section "Device"
+  Identifier "Intel Graphics"
+  Driver "intel"
+EndSection
+Again, a reboot is required for the setting to be effective.

 The only thing how to fix this, is a reboot, which you can only trigger from another terminal (Ctrl+Alt+F1) by typing
   reboot
+EDIT: killing cinnamon helps also
+  sudo pkill cinnamon
 ==== Mouse Traces ====
 It is mentioned on displaylink.com, but it also happens on the native monitor, when the USB monitor is connected. This is somehow annoying, but not critical.
+==== Using ARandR helps ====
+The most recent problem was, that I couldn't get the USB monitor running on the left side of the notebook. The Cinnamon Display Manager failed to apply the config.
+With [[https://christian.amsuess.com/tools/arandr/|ARandR]] I can switch the config and apply it as needed.
+  sudo apt install arandr
+With ARandR you can save several configurations in
+  ~/.screenlayout
+. The configs are shell scripts which can be run with a double click from the file manager or started from a terminal, which could be handy, if cinnamon "crashes".
 ===== Unsing on Windows =====
 Using the monitor on Windows 7 is without any problems - even the rotation of the monitor to portrait mode is detected on the fly.
