Thanks Petter! So the problem came up again after i last wrote (i had to go do some chores, and when i came back keyboarding and mousing did not bring back the display). So i tried your suggestion of restarting lightdm. And it worked, so thanks! I did lose my X state, but i don't think any other state. This seems to indicate that lightdm is going into too deep a sleep, or perhaps taking something to sleep with it that should stay awake. If anybody has any advice about how to approach this kind of lightdm problem, i'm all ears --- although i know next-to-nothing about lightdm. Thanks again everybody for all the suggestions. They were all helpful. dan -- xubuntu-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/xubuntu-users
