Sure, but I would prefer to speed up the resume stage as I use it more often. Currently it spends ~15s (not sure, as I don't have my 701 here). Do you know how can I debug it? I've activated the pm-utils logging and it runs in less than one second. I've used bootchartd to record what is running, but it is resumed too late to debug it. > >>> How much of this work can be applied easily to Debian? > > Thinking about the things that Arjan & Auke have done in turn: > > They have made some kernel changes to increase concurrency between > subsystem initialisations.

Yes, but for now is there a way to generate a xorg.conf automatically the first time and use it afterwards? Thanks Santi P.D.: Just say Hello, as it is my first post in the list (apart from a bug report). _______________________________________________ Debian-eeepc-devel mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/debian-eeepc-devel
