Re: [Xmonad] MATLAB and Xmonad

Does SetWMName hack work when you are starting the MATLAB on local machine? Are you pressing the keys which set the WM name before the start the MATLAB? Once the JVM inside which the MATLAB is running has been started, changing the name of the WM does not affect this particular JVM (it only checks which WM is used once on startup). If this still does not work, can you please try adding AWT_TOOLKIT=MToolkit line to the ~/.ssh/environment and make sure that it gets into the environment of the remote machine at startup of your ssh session.

Hi Ivan,

I still have some trouble with MATLAB. As I reported earlier, the AWT_TOOLKIT=MToolkit hack worked for me, but - as I discovered later - only if I run MATLAB from the local machine. If I want to spawn it remotely on one of our computing machines (via ssh -X) nothing will show up at all.

Today I tried it with your SetWMName extension (for which I needed to change from 0.3 to darcs), but it doesn't work :-(

As in the module docs, I use setWMName "LG3D" (I tried to put it in my logHook first, and also triggering manually via a keypress), but the error is still the same (just blank grey screen with menus popping up properly but no widgets at all).

I am thankful for any suggestions.

Best regards, Christian

I'm the author of SetWMName and I can summarise the issue, however I already tried to do this in the comment in the beginning of the SetWMName.hs. If it is not enough, please advice on how to improve the summary.

If it is possible, you should use the SetWMName instead of setting AWT_TOOLKIT=MToolkit, because MToolkit (Motif, actually) is an old engine for AWT and it doesn't support all the features needed to make the Java GUI programs work (some programs work, some do not). Setting WM name is quite a dirty hack, but it is the only way to work around the problem till, maybe, JDK7 (and there are no guarantees we'd have anything fixed there).

could someone summarise this issue generically, with the fix
