In September 2017, I posted a question asking if instant plug-n-play capability for external monitors could be developed in LL (see
https://www.linuxliteos.com/forums/suggestions-and-feedback/pclos-instant-plug-and-playexternal-monitor!!!-can-we-have-this-with-ll/msg35043/#msg35043).
My own experiments showed that Manjaro and PCLinuxOS could instantly plug-n-play with either our Samsung TV monitor or with two other displays (Dell & Hanns G). However, LL and all the Ubuntu-based distros that I've tried, did not instantly plug-n-play; instead you need to fiddle around with settings, e.g. which one is required as the primary display and whether mirror displays are required or not, etc, which is time consuming and a bit complicated.
Jerry suggested that the issue might be kernel related as, at the time, Manjaro & PCLinuxOS were using kernel 4.6, while LL still had 4.4. To test this idea, I did the following two things:
(1) Upgraded kernel from 4.4 to 4.6 then 4.9 for LL: still no plug-n-play with external monitor
(2) Downgraded kernel from 4.9 or 4.6 to 4.4 with Manjaro & PCLinuxOS: plug-n-play capability maintained
Therefore, I concluded that the lack of instant-plug-n-play capability of LL (or other Ubuntu-based distros) with external displays was not due to the kernel.
My question therefore, thinking about LL's future, is as follows ...
Would it be possible to develop external display plug-n-play capability in LL, even though this feature appears to be absent in its Ubuntu 'parent' ? Such a feature would be really useful.
Many thanks for any feedback.
