Public bug reported:
Hi
I'm using Ubuntu Karmic 9.10 64 bits on a dell latitude e6500 (fresh
install + updates) (+ compiz enabled)
* uname -a : Linux mydell 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:02:15
UTC 2009 x86_64 GNU/Linux
* /pvoc/version_signature : Ubuntu 2.6.31-16.53-generic
When I close the lid with the DC power plugged in, the laptop suspends
just fine.
If I reopen the lid, it will exit suspend mode and ask for my password
(locked session) as expected.
However if I unplug the power cord while in suspend mode and then reopen
the lid, it will exit suspend mode and ask for my password *and*, after
about 1 second (not long enough to type my password :-p), it will re-
enter suspend mode. Then I can resume simply by pressing the power
button (it then go back to the password-locked screen and I can unlock)
If the laptop is already on battery when closing the lid, the
suspend/resume works fine.
This only happen if I do "on DC + close lid + unplug DC cord + open lid"
combination
If I use any other mean (hold power button and select "suspend" option
in menu, use suspend button on the keyboard, use top-right corner menu
of Gnome --> suspend) to enter suspend mode, this doesn't happen (even
if I then add the "close the lid, unplug DC cord and open the lid" after
entering suspend mode, it will resume properly)
Reproductible : always
Power manager configuration : I use the default config
Package : ???
In the attachment (dmesg.log), the laptop enters sleep mode at
[59884.207720] (=close lid) and at [59894.240039] (=open lid+wake
up+sleep again)
PS: except for this bug, suspend/resume/hibernate work perfectly well
:-)
