#348 closed System Defect (fixed)

Power Management crashes my laptop.

Reported by: fitzlt Owned by:
Priority: major Milestone:
Component: System Tool Version: 8.1
Keywords: power management Cc: trac-bugs@…


Everytime Power Management automatically changes the status of my laptop( into standby, hibernate or powering down) my laptop becomes unusable.

When in standby or hibernate, my laptop will appear to wake up, but the screen remains black and will not turn back on. When it is shutdown automatically, I get an error saying that the host could not connect to the X server. If I restart the computer, I will get that error for all three situations. Once I get the error, I have to manually shutdown my computer with the "shutdown -p" command and WAIT 10-15 minutes before I turn it back on(any less than 10 minutes and I will only get the error again).

To avoid the problem to begin with, I have to start/shutdown the computer manually.

I also want to point out that manually putting my computer into hibernate(suspend to disk) results in the computer going to standby(complete with error). Selecting standby(suspend to ram) results in the screen saver turning on(error is 50:50).

I have a Sager NP2096 laptop and am running 8.1.

I was incorrect on the error message. Here is the exact message I am getting:

login: Sep 2 08:52:14 pcbsd-5612 kdm-bin[2330]: x server up timeout, terminating
Sep 2 08:52:19 pcbsd-5612 kdm-bin[2330]: x server for display :0 cannot be started, session disabled

Sorry for the error. Hope this helps.

New issue. All day today, I have manually shutdown and powered on my laptop. Tonight, I powered on my computer after a manually shutdown hours earlier today and I received the error from my previous post. I also was looking through my hidden files/folders and found a file called ".xsession-errors" in my "home" folder. I wanted to attach that file with this post, but it is 1.3 MB. If you like this emailed; just let me know. Thank you.

Is this still an issue in 9.0? If so, do any sysctl values fix the issue? Tips to get you started experimenting on your hardware are at the beginning of

Marking as fixed. Please reopen if still an issue on 9.0 after experimenting with ACPI sysctl values.
