Details

Description:
Under the tab Startup Applications it is not possible to add a new application.

Additional info:
* Version : 3.12.0-1
* Clicking the "+" button produces this output:

Traceback (most recent call last):
File "/usr/lib/python2.7/site-packages/gtweak/tweaks/tweak_group_startup.py", line 194, in _on_add_clicked
set(self._get_running_executables()))
File "/usr/lib/python2.7/site-packages/gtweak/tweaks/tweak_group_startup.py", line 210, in _get_running_executables
os.getlogin(),'-o','cmd'],
OSError: [Errno 2] No such file or directory

* This appears to fix the problem: https://bbs.archlinux.org/viewtopic.php?pid=1414443#p1414443 (I haven't tried it though)


Steps to reproduce:
* Open gnome-tweak-tool
* Go to "Startup Applications"
* Try adding an application by clicking the "+" button on the bottom.
This task depends upon

This is a problem coming from either python2 (and python) or the kernel.

os.getlogin() first tries to read /proc/self/loginuid (requiring CONFIG_AUDIT=y, which we don't have) and if that doesn't exist, try to determine the user logged in on the process' controlling terminal by reading utmp. Since processes started from X sessions typically don't have a logged-in controlling terminal (unless started from xterm), the call fails.

Personally, I'd like to have AUDIT back, since I was making use of loginuid myself.

See http://bugs.python.org/issue584566

So it was a wontfix upstream since more than 10 years ago. I'd suggest to report to the gnome-tweak-tool upstream, according to the BUGS section of getlogin(3), use getpwuid(geteuid()) instead.

In Python, it would be something like this:

>>> pwd.getpwuid(os.getuid())
pwd.struct_passwd(pw_name='felix', pw_passwd='x', pw_uid=1000, pw_gid=100, pw_gecos='Felix Yan', pw_dir='/home/felix', pw_shell='/bin/bash')

fixed now 3.24 (and also upstream)

so we can close it
