I created a my-app.desktop
file for a program I wrote. When I double-click it, I get the error message "There was an error launching the application". How can I get more detailed information about what the problem is?
I saw a reference to a "details" section of the dialog box, but there is nothing like that present in the one I see. If I were on my Mac, I'd open the Console app to see if any errors were logged, but I haven't learned of anything similar on Ubuntu.
(Note that unlike other similarly-titled questions, I am not asking what's wrong with this particular .desktop file; I want to know how to find out in general.)

Here's a trick you can use. Create a wrapper script for your application that will launch it and capture the error output:
Save that as
~/foo.sh
and make it executable withchmod +x ~/foo.sh
. Now, point your desktop launcher to it instead. Something like:That will redirect any error messages to
~/myapp.log
and you can examine them at your leisure. You can use2>>~/myapp.log
if you want successive error messages to be appended to the file instead of overwriting it.As an aside, the reason that the
$PATH
is different is because you are probably setting your$PATH
in~/.bahsrc
which is not read by the graphical environment. It is also a bad idea since the$PATH
will be set every time you open a new terminal and that is needless overhead. Use~/.profile
for this instead. For more details on which files are read when see here and for more on which file should be used for what, see here.
