On a fresh install of openSUSE 12.3 on my Dell Latitude D505, the machine crashes when I close the laptop lid. The strange thing is that all other power management functions work:
[ul]
[li]In the “System Settings / Power Management” dialog (opened using the confusingly named “Configure Desktop” entry in the Start Menu) I can:[/li][LIST]
[li] Configure “Suspend Session” to enter sleep mode after a fixed timeout, and this works fine. [/li][li]Configure the system to sleep when the power button is pressed, and it also works fine. [/li][li]Set it up to enter hibernation instead of sleep in the scenarios above, and it also works. [/li][/ul]
[li]I can regulate screen brightness using the Fn + Arrow Up/Down keys. [/li][/LIST]
Configuring it to “Do nothing” on laptop lid close does not solve the problem.
When the lid is closed, the screen blanks, but the backlight remains on, and the machine freezes (including SSH sessions from other machines). This state persists even if the lid is opened. The only remedy is to power down the machine (by holding the power button).
This is a regression - on 12.2 all laptop power management functionality worked beautifully.
I considered filing a bug report about this, but since I haven’t found any information that might be useful for pinpointing the problem (no log entries are written on the crash) I decided to try the forums instead.
Does anyone have an idea how to solve this?
