[Solved] How can I make sure (in the config files) that pcmanfm does not attempt to mount anything

[Moon-Moon]

Situation

I updated to LXDE 0.99.2 (pcmanfm 1.3.2) today, which broke my LXDE for my main non-root user (the account I usually use). I have always started LXDE with startx, where ~/.xinitrc specifies

Code: Select all

exec startlxde

Actual outcome

pcmanfm now attempts to mount all devices defined in /etc/fstab, including the ones with option noauto, when I start LXDE (with startlxde). This includes cifs devices that are not even reachable. But more importantly, it attempts to read passwords (which ís absurd and not possible in this setting) and for this blocks all input devices.

Expected/Desired outcome

I just want it to stop trying to mount anything. There is no reason in hell why LXDE or pcmanfm should interfere with my volumes.
I want to accomplish this directly in the config files. Hopefully, I can then be sure that it never happens again.

Attempts at solving this

Here is where things start to get very weird.

I tried:

• Another user. Works fine.
• A new user. Works fine.
• Removing the files relating to LXDE and pcmanfm in ~/.config and ~/.cache. Changes nothing, does not work for my main user.
• Additionally setting

  Code: Select all

  mount_on_startup=0
  mount_removable=0 
  autorun=0

  in /etc/xdg/pcmanfm/default/pcmanfm.conf. Changes nothing, does not work for my main user.
• Hiding all config files for all applications for my main user, hoping that LXDE and pcmanfm will start with system defaults again. Changes nothing, does not work for my main user.
• Copying the (automatically generated and working) config of the newly created user to my main user (and chmoding to set ownership correctly). Changes nothing, does not work for my main user.
• Renaming the hostname (I thought my main user having the same name as the host name may be the reason). Changes nothing, does not work for my main user.
• Starting openbox instead and running startlxde from a terminal in openbox. This time I get the password prompts and LXDE works again.
• Restarting (Windows magic, should not be necessary on Linux); Indeed, changes nothing, does not work for my main user.

I don't understand how this can possibly happen. If it works for other users, it should work for my main user when I remove the config (or when I remove all configs for everything; actually all files). Since it does not, there has to be some other record that marks out my user so pcmanfm can annoy this user specifically. It's not the username being identical with the hostname or so, so it has to be saved in some file.

In the end, I'm not sure I care if any how pcmanfm can mark out my main user. I just want it to stop messing up my LXDE startup with attempting to mount volumes that are not there (or any volumes at all for that matter).

What it looks like:

/etc/xdg/pcmanfm/default/pcmanfm.conf

Code: Select all

bm_open_method=0

Note that none of this is out of the ordinary. I have all these messages also for other users and I believe I had them before the update.

Hi Moon,

Have you got gvfs installed? More important - have you got udisks2 installed with polkitd
https://www.freedesktop.org/wiki/Software/udisks/

also see https://wiki.archlinux.org/title/PCManFM

With Synaptic PM you could mark pcmanfm for reinstallation which should restore config files to standard...?

I have LXDE + Openbox on antiX-22 Full and antiX-23 Base where it handles mounting of camera NX-mini, Pixel GrapheneOS phone, Motorola g6, 1TB External Drive and multi USB pen drives without trouble.

Good Luck

[Moon-Moon]

Hi Ziggi,

thank you.

Yes, I have gvfs 1.52.2-2, udisks2 2.10.1-2, and polkit 124-2.

I do not know Synaptics PM. However, I have never changed the pcmanfm config files manually before this week (when I edited /etc/xdg/pcmanfm/default/pcmanfm.conf in my attempts to prevent it from attempting to mount all the cifs filesystems from the fstab, i.e. after the problem occured). As a result, I would not expect restoring the config files to standard should change anything. In addition, as I explained, LXDE works for other, including newly created users. Further, reinstalling with

Code: Select all

pacman -Sv pcmanfm

does take care of overwriting all the config files, including restoring my changes to the volume section of /etc/xdg/pcmanfm/default/pcmanfm.conf (setting everything to 1 again). This does not solve the issue.

Additional piece of information:

Code: Select all

ps auf

does indeed show

Code: Select all

pcmanfm --desktop --profile LXDE

as the parent process of the mount.cifs processes.

It turns out that for my version of LXDE at least,

Code: Select all

...
[volume]
mount_on_startup=0
mount_removable=0
autorun=0
...

needs to be given explicitly in the local pcmanfm config in ~/.config/pcmanfm/LXDE/pcmanfm.conf. It appears that the global config in
/etc/xdg/pcmanfm/default/pcmanfm.conf is ignored even if no local config file exists. It is conceivable that this behavior has changed from the previous version (hence the problem appeared after the update) or possibly even that my local config file somehow got deleted with the update (I did not pay much attention to it before).

If the issue persists, make sure to review any system-wide startup scripts or configurations that might be affecting your user specifically. Files to check include: Pizza Tower
/etc/xdg/lxsession/LXDE/autostart
/etc/xdg/autostart/
Ensure there are no unintended commands that could trigger automatic mounting.

Sometimes hidden files (starting with a dot) in your home directory can cause issues. Run the following command to check for any pcmanfm or lxsession configurations:
ls -la ~/.config/
ls -la ~/.cache/
You can temporarily move or rename the relevant configuration directories for your user to see if this resolves the issue: Sprunki Game
mv ~/.config/lxsession ~/.config/lxsession.bak
mv ~/.config/pcmanfm ~/.config/pcmanfm.bak
