Hi and thanks for the reply
I certainly know what these devices are like and thank goodness I found Endless before my 9 year-old daughter stopped talking to me! The ‘fun’ I have had…
Endless has proved to be a dream for her and this laptop - so far it has been the only distro that detects the WiFi, Bluetooth and sound hardware and works perfectly well with them out of the box. My usual daily driver is Linux Mint 19 and my secondary machine runs an Arch based distro.
Booting up from a live USB in this machine with Mint (kernel version 4.15.x) detects the HDMI output and will display on the TV. Additionally, booting from a SwagARCH live USB (kernel 4.17.11) detects the HDMI output and also displays on the TV screen.
So I’m not sure that this is a kernel issue as such but may be either firmware not loading or loading incorrectly or the HDMI output giving out a signal that is somehow ‘out-of-range’ of the TV I am trying to use (it is a fairly modern Samsung 4K TV).
As I say, it’s not the end of the world - my daughter just wanted to show some friends some photos she had taken on the big screen so we just used my laptop instead.
I have done more testing today, as it happens.
If I plug the laptop into an older TV (that just about makes 1080i) the display is detected by Endless and appears to work OK.
That leaves us with the following:
Endless - working on older TV
Endless - not working on newer 4K TV
Mint - working on both TVs
ARCH - working on both TVs
Could possibly be to do with ‘detection’ of the TV by Endless or that Endless is giving a signal that is somehow out-of-range of the Samsung 4K TV.
