Hi,
I cannot have suspend and hibernate working on a Samsung NC10
(netbook) running CentOS 5.4 i386.
When I try suspending/hibernating the screen becomes black (with a few
logs, like "shrinking memory" for hibernate) and then the computer
hangs and I have to force a shutdown with the power button.
This wiki page seems to say that it should work out of the box:
http://wiki.centos.org/HowTos/Laptops/Samsung/NC10
I tried to add the kernel arguments described here, to no avail:
http://lists.centos.org/pipermail/centos/2007-June/040633.html
Anyhow the problems doesn't seem to be the resume but rather getting
into the suspended/hibernated state.
When I log after a failed attempt, GNOME shows a popup saying that
apparently we failed to recover from a suspend/hibernate state and
that this may be a driver problem.
A few more information about my settings which may be useful:
- the root filesystem is installed on an LVM
- I use the NetworkManager and not the network service
- I disabled bluetooth (in order to remove all unused devices that may
impact this problem)
- [mbaudier@localhost ~]$ lshal | grep suspen
org.freedesktop.Hal.Device.SystemPowerManagement.method_execpaths =
{'hal-system-power-suspend', 'hal-system-power-suspend-clear-error',
'hal-system-power-hibernate',
'hal-system-power-hibernate-clear-error', 'hal-system-power-shutdown',
'hal-system-power-reboot', 'hal-system-power-set-power-save'} (string
list)
power_management.can_suspend_to_disk = true (bool)
power_management.can_suspend_to_ram = true (bool)
power_management.can_suspend = true (bool)
Thanks in advance if somebody can tell me how I can analyse further /
solve this.
Cheers,
Mathieu
