No RC update channel on this device? I only get the development channel, and last few updates won't work, it just reboots to recovery.

I noticed ubuntu-restricted-extras is not present in the system image. Would installing it help in this regard (though I'm aware it's not recommended)?

I'm trying to install the latest updates on the development channel (for the Lenovo M10 Wifi tablet), but the process gets stuck at recovery after the restart prompt, and won't install any updates. It happened last week with version 308, and currently with 314 as well.

@Lakotaubp The Lenovo M10 tablet. I've noticed that this particular device only has the development channel listed on the official page, so I guess there's nothing wrong there, although it is unclear to me why that is.

Although I'm having trouble with the last couple of updates, but I'll open a new thread about that.

@Lakotaubp AFAIK there isn't an official release of 24.04 for my device, so my issue is related to 20.04.
I only get a '20.04 Development' channel on the settings, and I haven't found a reference to such an issue anywhere else on this forum, hence my previous comment.

I don't if it's just me, but I don't get any 'RC' channel on my System Settings, only 'Development'.

A cool feature would be to highlight selected text, or ideally a tool that would bind the highlight to the closest text in the document.

Anyone using this tablet has been able to get decent stylus behavior/functionality?

@AppLee Is there a way, though, to just check the media playback capabilities of the device? e.g. from the GPU model?

@arubislander yeah, the couple of apps I was trying to install did provide arm64 binaries.

Note that installing gnome-software works well, and AFAIK it uses flatpak to manage its applications. Apps on the Gnome repos usually don't work all that well, but it's perfectly capable to update the and install applications without any issue.

I've installed flatpak in a Libertine container, but I'm having trouble setting up the Flathub repository (following the official instructions on a libertine fakeroot shell):

$ flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
$ flatpak update --apstream
No such ref 'appstream2/aarch64' in remote flathub
No such ref 'appstream/aarch64' in remote flathub

And any call to flatpak install flathub <package> returns

error: No remote refs found similar to '<package>'

Is there something specific to the Libertine container that needs to be configured in UT, or am I missing something?

@arubislander I've looked at the logs per your suggestion, but strangely enough the app does not list any log pertaining to Sublime Text (which I would expect to find under focal_sublime_*), and I don't find any reference to it in any of the lomiri-* logs.

As an update to the initial question, lomiri-app-launch focal_sublime_0.0 reports Started: focal_sublime_0.0 with no error, but like with the desktop shortcut, nothing is launched.

Also, occasionally just clicking the app shortcut will fully kill/power off the OS.

I've installed Sublime Text with Libertine, and while it works well enough when launched from the terminal i.e. libertine-container-manager exec -c subl, the desktop/menu launcher in Lomiri is broken.

By default, sublime_text.desktop launches the executable directly:

...
Exec=/opt/sublime_text/sublime_text %F
...

instead of the launcher bash script /usr/bin/subl, but both work when launched from the terminal (both with libertine-container-manager exec ... and from a libertine shell) without any major issue. I've tried editing sublime_text.desktop to call subl, but to no avail.

Any insight as to what could be causing this and how to workaround it?

@arubislander the comment I replied was discussing the merits of the feature itself and not (just) the feasibility of its implementation, which, as you say, is dependent on interest and time from able developers. +1 from UT users can, at the very least, marginally influence the 'interest' part of it.

(and even if UT does not seek 'feature parity with Android', it's a fact that Android is the industry standard on the devices that UT is targeted to/developed on, and that UT aims to be an alternative)

@AppLee said in Ubuntu Touch Night Light Feature:

I don't have my sources available, but I read that there was no solid proof of it having any effect.

I don't think it's consensual, but a quick search led me to a recent scientific study linking blue light exposure to decreased sleep quality and cognitive function (DOI: 10.3389/fphys.2022.943108).
May be subjective, where some people benefit from it, some don't; in my own (admittedly anecdotal case) it has a noticeable effect in eye strain when working late, and particularly when using multiple displays with/without blue light filtering.

I'm just sharing so you can choose what is best for you.

Even if it's just a placebo, ultimately, for people to choose, the feature itself would need to be implemented, just as light/dark themes.
Not a priority by any means, but it would be cool to have this on UT, particularly when Android supports it.

Currently the upstream desktop version of Firefox is perfectly usable in Ubuntu Touch (at least in tablets), all that's missing is clipboard support and some extra gesture support.

@arubislander that did it, thanks.

Noting that, as of Feb. 2025, the methodology in the official documentation doesn't work.

@arubislander the Lenovo tab (X306F); admittedly, I had only tried with a couple of .mkv files, which don't work. MP4 videos seem to be working fine. But can't one install codecs for MKV?
I can play them with mpv and vlc through Libertine, but playback is choppy.

@kugiigi I do have a 'X11 support' running anytime I load up firefox, not sure if that's a staple of xwayland or xmir.

Unsure if I there is something missing on my end, but I can't play any video on the default UT media player.
