Dual external monitor
-
@Lakotaubp, so it looks like there is a stable channel already. Thanks for the link.
Does anyone know if the dual monitor dock works with the Fairphone 5 or any other device?

@MrClayPole said in Dual external monitor:
Are dual external monitors supported?
All I can say is FP5 under android support wired external display with display port over USB-C, which FP6 is not capable of.
And at least its device page says it supports one external wired display under Ubuntu Touch.

yes but it may not support all the good stuff, see for example:

@gpatel-fr
This issue is for Fairphone 4.
Also, not everyone is in urge having VoLTE working, specially concerning Fairphones devices as the VoLTE issue concerns mostly USA where Fairphones are not sold directly (only from murena and at slightly higher price thanks to the orange agent tariffs). -
You'll have to look up if the hardware of FP5 supports it. Honestly, I doubt any phone supports dual external display
-
@kugiigi thanks, I thought it was as long as you had DisplayLink, then it was down to the software. Looks like I was wrong, and it does look like it's hardware limit-based on my searches.
-
@MrClayPole At least for me, all three displays connected to my dock can show a cloned desktop. At least when I boot with already connected dock. But dedicated deskops on multiple monitors are not possible.
I got the best experience, with only one display connected to the dock.
-
@MrClayPole Oh DisplayLink? Yeah no, that definitely won't work in UT. That is a proprietary tech that needs a software or app or something. It's actually a nice tech because the device doesn't need to support display out but it needs the app on Android.
-
@MrClayPole no Lomiri does not like more then one monitor.
didn't stop me from trying, it made for a cursed mirror setup where on screen is having a stroke and the other was perfectly fine. -
@Keneda Btw, i have a fp4, and have found that installing over the Android 13 rom from fp works without issues, though it does seem that I need to disable ipv6 in the kernel tunables to get things like waydroid to work correctly, but I'm not sure if thats related.

Did any of you try touchscreen monitors, and if so, what model and was anything not working?
-
@GooglyBear I have a portable one. Touch works but not correctly because it maps to the built-in screen so it interacts with the touchpad. I believe this is something that Mir needs to support.
-
@kugiigi Thanks for posting your experience, did you post / find an issue on gitlab regarding it? I am interested in Ubuntu Touch development, so if I get the chance I'd like to work on that, because if something like that worked it would allow portable convergence, which is what I'm after.
-
@GooglyBear Sorry I can't remember if I did but you can check the Ubuntu Touch repo or Lomiri or Mir.
I did asked Mir developers about it and they said even the latest version at that time didn't support it.
Fun fact, even Gnome has this problem, it can't properly map multiple touchscreen displays. KDE however does. -
@kugiigi Good point, even having a single external display already creates a 'multiple display setup' doesn't it? I wonder if temporarily disabling the main internal one would help make the larger external one function correctly. Sure, it's not ideal, but usability first!
-
@kugiigi Maybe this should work reliably: https://docs.ubports.com/en/latest/userguide/advanceduse/screencasting.html
You'd need to make everything tiny on the phone, putting it into a sort of 'desktop mode' (similar to what I was saying before). That way you would be able to make full use of the large screen.
-
@GooglyBear I don't know the technical details enough to be able to come up with a workaround
I tried some things, even modifying Lomiri codes, but nothing worked.
