Ubuntu on 2510p: closing lid causes freeze

[FND]

Hello all,

I am running Ubuntu 7.10 (Gutsy) on my HP Compaq 2510p, and I'm very happy with this setup*.

However, there is one persistent issue:
When closing the lid, all inputs are disabled (indicated by the orange touchpad button) and the system seems frozen.
Sometimes pressing the touchpad button reactivates the machine, but usually I have to shut it down hard.

This happens although I have disabled any such behavior (System > Preferences > Power Management > On AC/Battery Power > When laptop lid is closed: Blank screen).
I have also tried the following, without success: "sudo echo 1 > /proc/acpi/video/C099/DOS".

This is a very annoying issue, so I would be immensely grateful for any help!

Shalom,

Its unlikely that Ubuntu was tested on this hardware.

This problem comes from a lack of support and drivers for the hardware function that controls sleep for the OS.

I found this functionality was working ans present with my Toshiba Satellite laptop. I've found their support and driver structure, especially for Ubuntu is better than most.

As the laptop gets old and more widely known, support generally improves. I also found Ubuntu's hardware support, especially wireless to be the best among distros.

try to upgrade to hardy heron (ubuntu 8.04), it has much improved support for laptop things like hibernation/sleep as mine (a dell) works now too and didn't before with gutsy.

Thanks, I'll try the upgrade.
Will report back here once I have results (might take a while, as I'll need to create a disk image first, among other things).

FND,

Why are you creating disk images???
Gusty to hardy upgrade is simple and safe, you can do it by using software updater. When you check for updates it will show that a new release is available and you can click the upgrade button to go to hardy, with almost no downtime(you will need a reboot when the upgrade is done).

> Why are you creating disk images???

Simple paranoia - better safe than sorry.
Also, since I didn't know what I was doing when I first started with Linux a few months ago, I'll take this opportunity to start from scratch (re-importing only the essential bits of my current home folder).

I've finally gotten around upgrading to Hardy - and indeed, that seems to have fixed this issue!

Thanks everyone!

I get this same problem with OpenSuse 11.0 on this same laptop. Regardless of power setting, if the lid is closed, the laptop is totally frozen when it opens back up. Is there a known update for OpenSuse that will provide power management?

Quick update: I've noticed that hibernate doesn't work ("ACPI set timing mode failed") - suspend works fine though.
