I use x230 on dock station. I want to use laptop with external monitor and keyboard. On kubuntu power manager "when laptop lid is closed" is set to do nothing "Even when a externnal monitor is connected" is checked, but when i close laptop all monitors go to sleep. I want to use laptop with external monitor and keyboard. I use kubuntu 16.04 with 4.10 kernel
Multi-monitor support has been worked on a lot recently. Any chance you can upgrade to something more recent than 5.5.5 and re-test? Since you're using Kubuntu, you should be able to use the kubuntu-backports PPA to upgrade to 5.11.4: sudo add-apt-repository ppa:kubuntu-ppa/backports sudo apt-get update
Backports is already activated. I check "unsuported updates" on Update manager but may be this is relative for ubuntu backports so i add sudo add-apt-repository ppa:kubuntu-ppa/backports and make dist-upgrade now version is 5.8.8 And yes i test and now all work . When i close laptop monitor continue work and system make it primary withh start menu and etc. Also today i make attempts to fix microphone mute button work on my lenovo x230 without success , but now all is ok, even led indicator work. Also when search in discovery it works, before when search result always be o founds. I'm very surprised. Only problem for moments is fingrprint login not work. I install fingerprint-gui and yes it works with console and apps. But not work with login screen. But this is not problem for me. I wrote this only for info :)
Excellent, happy to hear it! FWIW, Discover is even better in 5.10 and beyond. I'm using Kubuntu 17.10 with the backports PPA as my home machine and it's a magnificent system.
