It's even more aggressive than setting framedropping to hard on mplayer. I decided to use --framedrop=no to have it get more out of sync instead. Thank you for the suggestion though, I might decide to switch to mpv. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

That's secondary, but in case you are interested, mpv gives better playback: https://forum.qubes-os.org/t/improving-video-playback-speed/21906/8 -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

I also tried an untouched version of debian 12 minimal with updates and only mplayer added from apt. There was no mimeapps.list file in /usr/share/applications, /etc/xdg/, $HOME/.config or $HOME/.local/share/applications. I tried xdg-mime default mplayer.desktop video/x-matroska as the non-root user. Still didn't work. Maybe because there wasn't a mplayer.desktop file in /usr/share/applications like in fedora. I copy over mplayer.desktop without a MimeType field from the original debian 12 miminal media qube and move it to $HOME/.local/share/applications. This gives the same error as the original media qube. I add MimeType=video/x-matroska to the desktop file and re-run the xdg-mime command. I still get the same error. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

I added the lines to mimeapps.list directly, although I think xdg-mime default alone worked for me too. I added a [Added Associations] line with the same entries as [Default Applications]. Not really sure what this does though. The mimeapps.list file I use is in /etc/xdg/ (global), so I set it from the template. Sometimes I've had to add a MimeType field (something like MimeType=video/mp4;video/x-matroska;video/webm) to the .desktop file being used, before running xdg-mime, to get it to work. > And there it is: xdg-open wrongly detects gnome3 which is not > installed.

I downloaded Fedora 39 minimal, it didn't have mplayer, so I tried updating and installing only kmplayer. It seems to install a lot of plasma, Qt stuff, about 200MB in total. After installing kmplayer it qvm-open-in-dvm didn't work. With journalctl in the fedora based vm it shows the same failed to connect to bus error as debian started with. After that it seems to just give an mime error, like the one you showed earlier. cat /usr/share/applications/mimeapps.list shows org.gnome.Totem as the default application. XDG_CURRENT_DESKTOP was set to X-QUBES, as with you. I copied mimeapps.list to /etc/xdg/ in the template and replaced -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

It used to work for me in debian-12-minimal too. Here is what I get when I "Open in VM" a text file (VM is based on debian-12-minimal with thunar, xpdf and mpv installed).

Tested with an mp4 file - same result. I can open the files through thunar, where I can set default app for the type too. However, thunar does not use xdg-open but exo-open. Next, I looked at the code of xdg-open (it is a shell script) and I saw it used some form of desktop environment (DE) detection and acted based on that. So, to see what exactly happens: $ bash -x xdg-open TEST.pdf ... + DEBUG 2 'Selected DE gnome3' ... + open_gnome3 TEST.pdf + gio help open + gvfs-open --help + open_generic TEST.pdf ... And there it is: xdg-open wrongly detects gnome3 which is not installed. Then I checked: $ printenv | grep XDG_CURRENT_DESKTOP XDG_CURRENT_DESKTOP=X-QUBES ## NOT XFCE, which is the correct value After: $ export XDG_CURRENT_DESKTOP=XFCE xdg-open works as expected in the current session. To have "Open in VM" work as well, obviously the above must be set persistently. Speculation 1 (needs checking and confirmation): Since I see in a fedora-xfce-template-based qubes the XDG_CURRENT_DESKTOP=XFCE, I suppose it is somehow set when XFCE itself is installed (and not just thunar), so perhaps the fact of the Debian template being "-minimal" (and not "-xfce") is related to this
