Both DEs tested now in a virtual world, both working ok; esp. speeds up KDE (otherwise uncredibly slow compared to Xfce). I figure desktop-autoloader to work with other DEs (like LXQt, Cinnamon) as well. On my TODO list: (1) disable desktop-autoloader cron job for thin clients (easy). (2) document how to enable and actually use autoloading (some work). Wolfgang signature.asc Description: PGP signature

Tests follow over the weekend. how did those tests go? I didn't get to testing. In fact, I only got to talking with people over the miniDebConf weekend mainly. However, Wolfgang did integration work. @Wolfgang: did you get a chance to test desktop-autoloader with GNOME and KDE? With XFCE it works. The best test is to enable the X11VNC debugging code and observe the session with a vncviewer.

Right. Noted for upstream, too. this should also be filed as a bug and fixed before enabling by default. Fixed in 0.0.4-1. > - has this been tested with other desktops than MATE? Yes. XFCE. We can do more tests, of course. The more consumptive the desktop env the more worth a test case. Noted. yes, please test at least KDE and Gnome as well. (third bug, untested on KDE+Gnome.)

And they appear even later on campus, at least here in Kiel. And it is, of course, localtime. And: cron.d files are editable. everything is editable. We *need* sensible default.

To pre-load heavy-load-regular-used applications (e.g. firefox, libreoffice) so without those .desktop files it would still to part of its job?

There will be a patch upstream for that, too. no, this is not what I ment: it must be described in our Debian Edu manual ( and upstream as well, I agree.) The desktop-autoloader now come in disabled state by default. It needs to be enabled in /etc/defaults/desktop-autoloader. Thanks for thinking about this, well, you are welcome, but I also expect more thoughts before suggesting enabling some new feature by default... :-) Mike -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby mobile: +49 (1520) 1976 148 landline: +49 (4354) 8390 139 GnuPG Fingerprint: 9BFB AEE8 6C0A A5FF BF22 0782 9AF4 6B30 2577 1B31 mail: mike.gabr...@das-netzwerkteam.de, http://das-netzwerkteam.de pgpbjlr6B0ifc.pgp Description: Digitale PGP-Signatur
