Hum, not sure if I understand that command. When I try to run it it
just gives me
cat: /proc//environ: no such file or directory
(Not sure if this is the right message in english, my shell is in portuguese)

The old trick of turning off and on again ;) I rebooted anyway just to be sure.

Yes, it works if I run it from st. I just wrote it from memory because
since it is a one liner it was easier for me to do that

That's it! Yes, I'm unfotunately still runing a display manager:
lightdm. I'm slowly getting rid of the bloat but I tried to remove the
package yesterday (I'm running Arch linux) but for some reason startx
didn't work. But, anyway, it turns out you do have an idea on how to
solve the problem! From the Arch Linux wiki:

"If you are migrating from xinit, you will notice that the display is
not launched by your shell. This is because, as opposed to your shell
starting the display (and the display inheriting the environment of
your shell), LightDM starts your display and does not source your
shell. LightDM launches the display by running a wrapper script and
that finally exec's your graphic environment. By default,
/etc/lightdm/Xsessions.conf is run."

LightDM does check ~/.xprofile, though. So I added the path (together
with other programs I want to launch at starrtup, such as slstatus),
and it now works.

Thank you very much!
