qubes-desktop-file-install is called by qubes-triggers-desktop-file-install. It's
arguments are based on the Gnome desktop-install-file utility to allow it to be replaced
by same. Currently the Gnome utility can not be used since it automatically validates
the .desktop entry files with no option to skip validation and will fail on some third
party .desktop files that are not formed properly.
A single trigger script is shared between Fedora, Debian. This script is used by the
package managers triggers and will copy original .desktop files from `/etc/xdg/autostart`
to `/usr/share/qubes/xdg/autostart` and modify the OnlyShownIn / NotShownIn, etc. The
original .desktop files are left untouched and left in place.
Qubes modifies the XDG_CONFIG_DIRS to first include the `/usr/share/qubes/xdg`
directory (XDG_CONFIG_DIRS=/usr/share/qubes/xdg:/etc/xdg).
If a package gets removed, it's desktop entry is also removed from the /usr/share/qubes/xdg
directory.
'qubes-desktop-file-install' options:
--dir DIR Install desktop files to the DIR directory (default: <FILE>)
--force Force overwrite of existing desktop files (default: False)
--remove-show-in Remove the "OnlyShowIn" and "NotShowIn" entries from the desktop file (default: False)
--remove-key KEY Remove the KEY key from the desktop files, if present
--set-key (KEY VALUE) Set the KEY key to VALUE
--remove-only-show-in ENVIRONMENT Remove ENVIRONMENT from the list of desktop environment where the desktop files should be displayed
--add-only-show-in ENVIRONMENT Add ENVIRONMENT to the list of desktop environment where the desktop files should be displayed
--remove-not-show-in ENVIRONMENT Remove ENVIRONMENT from the list of desktop environment where the desktop files should not be displayed
--add-not-show-in ENVIRONMENT Add ENVIRONMENT to the list of desktop environment where the desktop files should not be displayed
Restore support for older yum: no --downloadonly option, so use
yumdownloader.
Also add some a code to handle some Debian quirks - especially default
rpmdb location in user home...
Apparently it doesn't help much with DispVM startup time, but causes a
lot of problems when such app do not close in time (either can be killed
forcibly and will complain about it at next run, or will spontaneously
show itself when DispVM is started).
Instead of directly using Exec= line, parse the file (at the launch
time) with Gio library. The main reason for this change is to handle
Terminal= option, but generally this approach should be more
bulletproof, especially when some fancy options are present in desktop
files.
It looks to be related to this report:

Workaround idea was from comment 37.
The hanging process in Qubes VM is most likely dconf-service, but there
is a lot of possible causes. To start with a non-standard method of
accessing the X session (no real login manager, processes started by
qrexec-agent). So instead of wasting a lot of time on digging through
gnome services, simply shorten the stop timeout - the processes would be
killed anyway.
This better handles dependencies (especially of "Obsolete:" type).
Unfortunately yum install/upgrade checks if running as root. Because we
are only downloading packages, using local "system root" (--installroot
option) no real root access is requires, so use fakeroot to mute yum
error.
