Cannot save session

Open curiousercreative opened this issue 3 years ago • 10 comments

:ghost: Brief Description

Saving session with som applications fails

:pancakes: Action version

lwsm save SESSION_NAME

Steps To Reproduce

Steps to reproduce the behavior:

  1. Open lots of apps (Tilix, Nautilus, Gedit perhaps the culprits)
  2. lwsm save SESSION_NAME

:police_car: Expected behavior

Session should be saved and later restored by lwsm restore SESSON_NAME

:heavy_plus_sign: Additional context

Pop!_OS 20.04, 20.10 Kernel 5.8, 5.11

Here's the stdout from a save after I removed the re-throw of the exception (so that it would proceed with save and throw all exceptions):

lwsm save common-energy

Thanks for opening this up. Did you try going through the troubleshooting section for the apps that are not working?

johannesjo avatar Jul 07 '21 10:07 johannesjo

@johannesjo it's been a little while since I worked around this, so I can't recall if any of the troubleshooting was effective. FWIW, all of my apps open with my workaround...

curiousercreative avatar Jul 07 '21 13:07 curiousercreative

@johannesjo it would be a separate PR, but I have added this mapping to my config file for user installed flatpak Chromium: "chromium-browser.Chromium-browser": "org.chromium.Chromium.desktop"

curiousercreative avatar Jul 07 '21 13:07 curiousercreative

Looking at the logs I wonder why there are not desktop files found with the standard method. Maybe they are stored in a different location on your system? Would be good to know, so we can add it to the searched locations.

johannesjo avatar Jul 08 '21 10:07 johannesjo

@johannesjo it seems to find them as they are all restored. Or does alternative guessing approach mean looking for something other than desktop files? I believe the desktop locations including Chromium are standard search locations already. I only need that rule because the desktop file name doesn't seem to match the window name. Would it be helpful for me to send you a session file? I haven't looked at it very closely, but it doesn't seem to have any sensitive info in it...

curiousercreative avatar Jul 08 '21 15:07 curiousercreative

Or does alternative guessing approach mean looking for something other than desktop files?

Yes. It's a bit complicated. The first method uses the commands from the apps desktop files, which could contain additional startup params. The alternative approach checks /proc/${win.wmPid}/cmdline. Not really sure what all the implications are tbh, but I vaguely remember that the alternative approach didn't work for every app as expected.

Yes please. A session file would be helpful. If you don't want to post it here, you can also send it to [email protected] (though I would prefer to have it here ;)).

@johannesjo here it is. I notice multiple entries for apps for different display sizes/arrangements, but I was receiving the errors with clean sessions with a singly display size.

Thank you!

Would you mind posting also the output of locate gedit.desktop (from root)?

@johannesjo just now seeing this, sorry! I had to install locate (sudo apt install mlocate on debian/ubuntu/pop-os) but here's the output:

$ sudo locate gedit.desktop
/usr/share/app-install/desktop/gedit:gedit.desktop
/usr/share/applications/org.gnome.gedit.desktop

Thanks. How you can work around this is to manually provide a mapping for gedit in the main config file under ~/.config/lwsm/config.json. There under the key WM_CLASS_AND_EXECUTABLE_FILE_MAP you should add "gedit.Gedit": "org.gnome.gedit.desktop",.
