Compiz in xnest? Or other "safe" way to start comp

[RYX]

Hi! Does anyone know if it is possible to run compiz within an xnest? Or is there another safe way of coding compiz-plugins (especially wrapping handleEvent) without facing the risk of entirely locking up the desktop? I wrote a small script which should kill compiz after 30 seconds but it doesn't always work - I am still forced to reset from time to time.

I am open for any ideas ... :)

This might help, personally I just set up a script to start kwin after 10 seconds if I am debugging. Otherwise you can switch to another VT and restart compiz.

Thanks, I forgot the forum-search :oops:

I tried most of all methods described there (except gdb over ssh). I also tried using Xephyr instead of Xnest which supports a lot of the "modern" extensions. But with Xephyr I get "compiz: Root visual is not a GL visual" ... Would it work to launch Xgl within xephyr and then launch compiz on Xgl within the Xepyhr-nest? Obviously a lot of overhead, but I don't want to do this the whole day, it is only for testing critical parts like actions in handleEvent (I rebooted about 50 times within the last 24 hours).

You can launch Xgl without the --fullscreen option, it'll work just as Xnest...

I have a script which runs XGL in a window with Gnome (though you can substitute it with whatever you like).
#!/bin/sh
Xgl :1 -ac -accel glx:pbuffer -accel xv:pbuffer -screen 1024x720 &
# you can adjust the resolution. I use 1024x720 to see FVWM-Crystal panels while running XGL in a window
DISPLAY=:1
exec gnome-session

If you use Gnome, KDE or Xfce then you will have to run this script from Fluxbox or Fvwm (which don't check for other DEs) because Gnome/KDE/Xfce won't allow you to run 2 instances of it nor will they allow you to run another desktop enviroment.
I read somewhere that this other desktop enviroment detection can be bypassed but I forgot what it was and where I read about it.
Running this script from fvwm-crystal was enough for my needs.
