startlxqt: Consider LXQT_DEFAULT_OPENBOX_CONFIG

[palinek]

Use the LXQT_DEFAULT_OPENBOX_CONFIG as the predefined configuration for
openbox in case it is defined -> allow downstream to easily change the
default configuration.

[palinek]

Looking at the diff now... should we check the existence of $LXQT_DEFAULT_OPENBOX_CONFIG file?

[paulolieuthier]

I think so.

[luis-pereira]

IMO we should

[tsimonq2]

This would be especially useful for Lubuntu's switch to LXQt so we can use a custom Openbox file. :)

For what it's worth, even though my Bash is rusty, 👍

(this came from a discussion I had on IRC)

And on your question, although again, my opinion doesn't carry much weight (as I'm not an LXQt developer) I think that would be good to check for that.

[palinek]

The checking done...

[luis-pereira]

Ship it

[paulolieuthier]

GTM.
