Further experiments are: If I use my computer more than several hours (e.g.: I work on it) and I put it to sleep, it goes without problem into. Then I resume it, and use for a while again without any problems*. BUT: From this point, two possibility are there: 1. If I try to put it to sleep again, it cannot do that, and freezes. 2. If I switch it off, It doesn't do that: It reboots. (Of course switching off works fine, if earlier hadn't try the sleep-thing)
So as I noticed, this phenomenon doesn't come up so randomly (only if trying more than one time within minutes). Now I will reboot, and without leaving enabled the quiet kernel flag I will upload the dmesgs before and after suspend (waiting 10 minutes at least between suspend and resume) -- Laptop doesn't go sleep *always* https://launchpad.net/bugs/83079 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
