Re: [xmonad] Trouble configuring xmonad on gentoo

29 Nov 2007

      Hi Andrea,

Thanks for your reply. When emerging xmonad on gentoo,  a default
configuration file is installed to be edited. I added the file in the
attachment.
I tried to edit it, so that the "HintedTile" extension is available.

Thanks!
Nathan

I hope some gentoo guy will drop by soon and make my request useless,
but in the meantime, since I'm not a gentoo user, I would need to have
a copy of the file you modified, and also a brief description of what
you were/are trying to achieve with your modifications. This way I can
contextualize the error messages you get and provide some directions.
Cheers,
Andrea
