XFCE hibernation & WICD network restart (solved)

Hello,

I'm using XFCE on my laptop (lenovo t61) & am having some issues with hibernation.
Using the XFCE power manager suspend & hibernate both work beautifully (although hibernate only actually resumes if using tuxonice sources).
My only issue is when I resume I have to manually tell WICD to connect to the network.

This seems like it's probably a WICD problem, but networkmanager simply doesn't seem to work for me. Which is a shame as it looks pretty good.

What i'd like to do is run a script after resume - but I don't seem to get any relevent acpi events (despite acpid running) and I think xfce powermanager uses upower and so doesn't use any of the options or scripts in /etc/hiberate/

Any ideas?

Thanks

Robin Marlow

Hello,

You need to add a line with the kernel module name of your wifi adapter in the black-list config file.

In my case, I added ath5k and it worked as expected.

Thanks Xavier,

I've got my wifi (iwlagn 4965AGN) compiled into the kernel - so I didn't think I needed to whitelist it.
The wifi works fine once I've resumed - it's just the manually having to reassociate that is getting a bit tiresome & seems begging to be automated!

I think overall the problem is that I don't understand all this dbus/upower voodoo that is going on behind the scenes & can't find it explained well anywhere.

I think Xavier really does mean blacklist, not whitelist -- this will force the module to be unloaded on hibernate and reloaded on resume. Since the wireless device will be reinitialized, wicd will then connect it to a network.

You do this by creating a file in /etc/pm/config.d called something like "50modules", with the contents:

Recompiled my kernel with wifi card as a module and your advice worked a charm.

Thanks!

FWIW, on my Thinkpad X301 with an Intel 5350 AGN chipset, I don't have to blacklist the module in order to reconnect after hibernation (or suspend-to-RAM) -- it "just works".

My kernel is tuxonice-sources-2.6.38-r1 , and I am using wicd-1.7.1_beta2-r4 .
