@floem7 said in Has video/media playback improved?: mkv plays without problems in default app a .mkv file is a container format, so the ability of UT mediaplayer to play these files depends on what is exactly the format of media tracks in the file. If the video track is "standard" mp4 or theora or h264 and sound track is mp3 or ogg/vorbis, there will be no problem. If for example the sound is amr or video is 'microsoft' mp4, it will probably not work. It's not obvious to check on the format of a .mkv file under Ubuntu Touch, it's much easier under a PC running Linux where you can easily install mkvinfo (ffplay or gst-discoverer-1.0 will also be able to interpret the files to some extent).

@hlbkv gnome software can handle debs and flatpaks (and on Ubuntu also snaps I think). The app itself is a deb, so it is not surprising that it can be installed. The apps that end up being able to be installed with it are probably also debs.

@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.

@hlbkv said in How to uninstall/remove packages in a Libertine container?: as of Feb. 2025, the methodology in the official documentation doesn't work. I think it hasn't worked since the move to focal. But there is no one yet who has taken it upon themselves to update the documentation on that point.

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