[gm45] Closing laptop lid causes screen to freeze

Hmm, offhand it sounds like a bad lid status bug in the kernel.
https://wiki.ubuntu.com/X/Quirks#Intel No Display After Lid Close Quirks: i915/intel_lvds.c

I can confirm this is happening to me as well on Asus U35F-X1, core i3. I start the music player, close the lid, and 10 minutes later when I open it back up the desktop is frozen but I can still move the mouse cursor. I cannot switch between applications that are already open. I can switch to console mode with Ctrl+Alt+F1 and issue sudo restart gdm. In power settings I have the screen set to blank when the lid is closed. I am running the Ubuntu Classic desktop 64 bit.

I forgot to add (in comment #3) that this was never an issue in 10.10 on the same laptop.

Running HP 550 laptop on 11.04 (32.bit) using Intel graphics

Having the same issue.

Screen is frozen but mouse still moves..

Same issue here. Ubuntu 11.04 amd64, kernel 2.6.39-0-generic.
Hardware: Clevo W150HN, Intel (Sandy Bridge) graphics.

Dell Inspiron 15xx with integrated Intel Graphics, same issue here: closing lid or letting screen blank causes unresponsive UI: mouse moves smoothly but cannot click on any windows or window decorations, nor any unity features. Keyboard unresponsive.

This looks like a pretty bad regression. Confirming and setting up to High importance.

Same is occurring on my HP Compaq 6730s. Did not have this problem in 10.10. And the problem doesn't occur every time, but most of the time it will.

The same problem is occurring on my Acer Aspire One 1410 (Intel GMA 4500HD) and on a Dell Inspiron 14. The two machines didn't have that issue in 10.10.

Happens to me on a Dell XPS M1330 with an integrated Intel GM965 that worked fine in 10.10.

Same problem with Inspiron 1525 and 11.04 with Unity.

If I switch to Ubuntu-Classic (with compiz) the sleep mode and closed lid work well.

Happens to me too on a Dell Studio 1555 in Ubuntu-Classic and 11.04

I also have this problem on my Acer Aspire 1410.

Sometimes (less frequently) the screen will also flicker rapidly between black, my background picture, and the expected display (open applications etc).

Does this happen to anyone else?

Inspiron 1525 with Unity, Also will freeze if lid closed for more than 5 seconds, but can move the mouse, and switch to console.
Also important to note, doesn't seem to freeze with I am on an empty desktop. I can have my mail and/or browser open, but as long as I am on a blank desktop, it does not seem to freeze up.
I have not extensively tested this, but seems to be a fact for me.

Same for me, also with an Inspiron 1525. I am midway through composing a document late in the evening. I flip down the laptop's lid, intending to finish the document in bed. I carry the laptop upstairs and flip the lid back up. Everything *appears* as it did before, and I can move my mouse pointer as normal across my screen. But mouse clicks and keyboard events no longer have any effect: the only key that does anything is the power button, which, if held down, shuts down the laptop. With no autosaving set, that means an hour's lost work.

I have the problem on a Lenovo SL500 (Intel GMA X4500) after upgrading to 11.04
Mouse moevable, but can't click anything.

Same problem on Dell Latitude E4200. Seems to work with Metacity, but with Compiz, X output (except the cursor; also input seems to work) freezes on lid close. Exiting early from /etc/acpi/lid.sh does not help. Killing and letting compiz restart helps (seems to need -9), no need to restart the whole X session. Does not reliably freeze, but rather often.

Same problem happens in Dell Inspiron 1525 with Intel Graphics chipset. In power settings, the lid is set to blank on close

Same problem on HP 6730b. Intel Graphics Media Accelerator (GMA) 4500MHD as integrated graphic card. Closing lid and opening causes display freeze. Only mouse is movable.

After few tests I see that when I disable gnome-power-manager (by killing process or disabling it in Startup Programs and restarting) screen is not freezing. Unfortunately gnome-power-manager is turning off screen when lid is closed and this will not happen when it's disabled.

Same problem on Asus K50ij.

Same problem on an HP Probook 5310m.

I hope this get resolved very soon, because it's certainly a bummer not being able to close the laptop lid on my computer. It's a potential deal breaker for me.

Same problem on Dell Inspiron 1440. Only the mouse is movable. I have to ctrl + alt + shift + backspace and log back in. Of course, doing that makes me lose my previous session.

Same problem on a Lenovo Thinkpad T420.

Same problem on Asus K52JC. Everything black, mouse is movable.

For the time being, I go to another tty and do a sudo service gdm restart. However, it's get restarted so everything that was unsaved or unseen won't be able to be recovered.

Killing gnome-power-manager completely has mostly fixed it for me on my HP 6710b, but it's still done the same thing upon two occasions in the past ten days (once about six days ago, once earlier today). I've probably closed the lid for the required length of time 10-15 times in that period. So I don't think that gnome-power-manager is the issue, but is rather just pretty good at triggering it.

And the "sudo gdm restart" technique takes it to the logon screen and says that I'm logged in, but the session dies as soon as it tries to log in to it. (It does the same thing after hibernate the two times I've tried it, too. But I should test it more thoroughly and create another bug report about that; wonder how long it'll take before I get round to it.) Normal "switch user" works, however.

I guess this is a duplicate of bug #762918 isn't it?

The same problem on my Dell Vostro 3300
