Is that still supported? Doesn't work on 18.10 for me.

I updated it according to the instructions but doesn't work neither from the gnome extension or from the terminal.

Here is what trying to save a session outputs:

lwsm save test1 sudo: unable to resolve host user: Invalid argument 0x2000097 has no wmClassName.

Thanks for reporting. This should hopefully be fixed now.

[NinjaTurtle007]

Yes indeed, it does work now but still throws out errors for widely useds apps like, telegram, keepassxc, calc, toggl, etc

Not sure why it struggles to find the desktop file for so many of them.

Here is an example of the error for one of the apps:

`indDesktopFile cant find file; searched patterns []
util: Generic Error findDesktopFile cant find file; searched patterns undefined
util: [Arguments] { '0': 'findDesktopFile cant find file; searched patterns' }
Input Handler Error: No input for desktop file path for window "telegram-desktop.TelegramDesktop". Please fix this manually in config file for this session in ~/.lwsm/{currentSessionName}.json

LWSM was unable to guess the location of your executable/desktop file.

Sorry for the very late reply. If notice any missing apps, it would be really cool if you could provide a PR to this file:
