http://askubuntu.com – I can move my mouse around, see wall paper and top panel or switch to ctrl-alt-F1. But I cannot click anything nor do any key combination work. What should I do beside restart lightdm? I chose to suspend because I don't want to lose my data. If I have to restart lightdm every time resume from suspend, I'd rather shutdown my computer. how can i get normal suspend functionality back? (HowTos)

Stories similar to when resume from suspend, my desktop went frozen

I am more or less a complete Linux noob, and using 12.04 for the first time. Everything works great, and I am very happy, but there is one exception: suspend won't resume. Every time I suspend my computer, (whether by clicking suspend or by closing the lid) it goes to a black screen (with the backlight on) but there is no way to wake it up.

Can't Resume After Suspend 48 weeks 6 days ago

After a kernel update from 3.3.7-1 to 3.4.0-1, my AMD64 F17 desktop system will no longer resume from suspend. The keyboard has no effect. When I hit the power button, I can hear the disk spin up, but the system is still unresponsive. /var/log/pm-suspend.log shows a normal suspend, but nothing else ( a successful resume will start with an "Awake" entry after the last suspend entry).

Well, resume on USB works really well with all forms of suspend/hibernate and also (my favorite) suspend-hybrid.

However, I have 2 issues. I've searched around, but I can't seem to find anything posted that works for me.

1) I don't seem to be able to wake my frontend using my MCE usb ir remote. It worked the first time I tried (but maybe I just bumped the mouse?).

My system is able to resume from suspend only after I've let it hibernate:scratch:.

When I do a fresh boot and suspend the system just after the desktop started, resuming will result in a black screen and I had to power off the computer (see pm-suspend-kde-fail.log).

Hello, new user to Ubuntu Netbook Remix and had a question about resuming from suspend. I have a Toshiba NB205 netbook and I have the classic issues that come with it being installed with Ubuntu, no bluetooth and no speaker output. I was able to get my bluetooth to work with the omnibook-source code, but only when I boot it up.

I've got a Thinkpad T400 with Gentoo Linux installed. Suspend-to-RAM works like a charm.

However, Susped-to-Disk doesn't work: if I suspend, the Laptop powers down and accesses the HD for around 30s.

Hi,

Tangerine doesn't play well with suspend/resume. It is unavailable on resume - I have to use killall tangerine and then restart it.

Is there a way to do this via a script for suspend/resume?

Where would I put the script?

Thanks, CH

Black screen after pm-suspend 39 weeks 4 days ago

I was able to get the pm-hibernate (suspend-to-disk) functionality working by following the wiki . . . .

This is not 100% reproducible, but occurs at least half the time.

I am using Fedora 18 on my laptop (HP EliteBook 2540p) with the MATE window manager. After installing lightdm to replace gdm, I can set my laptop to suspend when the lid is closed. However, when I resume by opening it and pressing the power button, it often wakes only briefly (a few seconds) and then suspends again.
