LXDE: PCManFM freezes all the time

It's now gotten worse: impossible to use PCManFM as it constantly hangs and I have to restart it by clicking its pinned taskbar icon. Occasionally even Leafpad and terminal application crash.
I'm trying Openbox and it works okay, so whatever LXDE puts on top breaks it. Maybe LXSession, PCManFM or libfm etc.
Maybe someone have various LXDE modules I could try please, newer or older versions?

Hmmm... That's odd. I've never seem LXDE crashing, but I have to admit that I haven't been using it that much. The build used was this one:
http://ponce.cc/slackware/slackware64-current/lxde/
After the crash do you see anything in the terminal (ctrl + alt + f1)?

@fulalas, Any upgrades since then, do you know? Or should I maybe downgrade to an older version?
No additional reports on the terminal (ctrl + alt + f1). A wild guess is LXDE might not like my disks: the host disk is NVMe SSD and I use two USB sticks.

AFAIK, LXDE isn't updated anymore. So it's unlikely that we'll see any bug fix
You can try to open PCManFM from a terminal, so when it crashes you may see something.

PCManFM (and libfm) still appear to be updated. Perhaps my issue is also reported here
https://bugs.launchpad.net/ubuntu/+sour ... ug/1782984
However their current solution to downgrade the menu-cache to 1.0.1 doesn't apply because it is already:
Code: Select all
/mnt/live/memory/images/003-lxde.xzm/var/log/packages/menu-cache-1.0.1-x86_64-1ponce
Starting pcmanfm from a terminal launches it and returns; after a crash no errors are sent to the terminal anyway. Various logs don't show anything either.
Have tried on a different USB: after a while, and after some innocent customization, PCManFM started crashing again. One possible correlation I think I'm seeing is that it happens more often when I run wine64 apps.

You're totally right! They decided to continue developing it! That's cool! Do you know how to build it? Maybe you should try (both libfm and PCManFM):
https://sourceforge.net/projects/pcmanf ... elease%29/
Together with menu-cache provided by ponce.
I'm wondering if they fixed that annoying PCManFM issue where you can't navigate back/forward with mouse buttons when in List View mode.
But, yes, Wine is totally messy. I don't trust my system when I activate it, especially if I also activate lib32 compatible.

OK, PCManFM now started crashing as frequently as before. I no longer suspect Wine or anything else as a direct cause.
I'm going to try your new module now (after it actually finishes with "Upload still in progress…"). Thanks. Previously, an updated module provided by @ncmprhnsbl in
File Manager for LXDE (Post by ncmprhnsbl #66681) didn't fix the issue -- made it worse even.

Your new module works fine so far: no freezes yet today. I hope this will hold. If not, I'll let you know. Thank you so much! The only feedback is that it (currently?) comes with a quite basic appearance and I can't really change the theme as I used to in the old LXDE. But if that's the price to pay for the stability, it's totally worth it.
UPDATE: It's just crashed for the first time. If it starts crashing more often than once a day, I'll post another update.

OK, so it crashes often now. There is a log file I haven't looked at before, '/root/.cache/lxsession/LXDE/run.log' and it has these lines at the time of a crash:
Code: Select all
pcmanfm

[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.

It does indeed feel like a multi-threading bug.

This is really odd. I don't know what to do. Maybe you should report this bug to them.
BTW, I've just updated the module, same link -- it's still a working in progress, but at least now you have a decent theme

Thank you for an update. Still crashes of course. I've submitted a bug to them. By the way, the About dialog still shows: PCManFM 1.3.0 (and LibFM ver. 1.3.1), notice that you said you used pcmanfm-1.3.1 -- did they forget to update the About screen?

That's weird! For me it shows PCManFM 1.3.1
Have you tried booting in Always Fresh mode?

Yes, sorry, I've had an old pcmanfm module. Now, it's PCManFM 1.3.1. Actually, I now have to retest it to confirm the problem still present. Let us put this on hold for a while: let me see if/when it starts crashing again and i'll post then. By the way, thanks again for buidling a next LXDE for me to test and for the future releases of porteus. Do you happen to have a newer openbox module for me to test, or someone else is taking care of Openbox DE?

Well, the new version PCManFM 1.3.1 still crashes with the same error message as above, although less frequently now. Thanks for your help and I hope my bug report will draw attention from the maintainers. I'll stay with it for now, until it becomes too much and then I think switching to OpenBox is an option -- no crashes there in my tests so far.

Or you can try Xfce. Thunar (file manager) is faster than PCManFM
