With this patch Sawfish honors aspect ratios when resizing a window interactively.
Patch testing Edit
I've only tested it with MPlayer, xprop can reveal if a window requests a specific aspect ratio. Without the patch, one can modify the height or width of an MPlayer output window independently, with the patch applied modifying the height of the window should change the width too and vice versa.
P.S. in the MPlayer case, content scaling depends on video output used. (^__^)
- Copy/paste the patch listed below into some file, eg.
- If you don't have sawfish sources yet, have one, as described get it from GIT repo.
- Go into the directory where sawfish sources reside, eg.
- Test if the patch applies cleanly with this command:
patch -p1 --ignore-whitespace --dry-run < TEST.diffin case of problems try also:
- If it applies cleanly, then remove the
--dry-runfrom above command and run it again, otherwise ask on the mailing list.
- Compile sawfish:
./autogen.sh && make
- Install it for testing, but it depends on your linux distribution.
- It is always better to install sawfish as your distribution package, but it is different for each distribution.
- So you may try
make install, which will install sawifish in
/usr/local/share/sawfish/(if you have write access). But then make sure that you run the correct version and delete it from that directory afterwards, to avoid any conflicts.

- vote: yes. As the author I'm biased, anyway I would like to hear comments on how to improve it; Metacity seems to change gravity according to the edge used to resize a window, for example setting north gravity when using the bottom edge. --Aav 13:47, 8 October 2008 (UTC)
