Bug Description

Binary package hint: gnome-power-manager

With the option to turn black the screen when I close the lid of the laptop a error is created, because after opening it the screen remains black, and I have to suspend the machine with the fn+stand by combination of buttons to get the screen back.

I'm using Karmic.

I recall having this problem with my old (now dead) Inspiron 8100 back with Hardy Heron. The screen would just blank when I'd close the lid, but when I'd open it again, the screen would not kick back on, it would just remain black.

I too am having this problem with clean installations of 9.10 Karmic on two dell laptops. Both are running integrated Intel graphic cards. Power settings have been set to "Blank Screen" on lid close. The system is still running in the background, CTRL+ALT+F1 and F7 are working in the background, but do not turn the screen back on. The screen's power is just off and won'y come back on.

I'm sure some of the many previous workarounds might have some success, such as using a script that calls the command "vbetool dpms on".

e.g. https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/49521/comments/22

If you have an SSH server running on this machine, you can probably just remote in from another computer and run that command.

I've had this issue before but not since version 7.10 or so. Something has changed obviously.

Just to add to this thread, I ended up creating a Gnome keyboard shortcut (Ctrl+Super+P) which executes "vbetool dpms on". When the screen in non-responsive, I use the key combination and it turns the power back on.

vbetool needs root privileges, so I just used the setuid attribute so normal users can run it.

sudo chmod +s /usr/sbin/vbetool

Hey guys, is there any chance you could test this with the live environment of the Desktop CD of the development release - Lucid Lynx. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/. Thanks again and we appreciate your help.

Hello Teej I tried to test it but after I did the upgrade to Lucid all my network interfaces were shutdown and I was not able to brig it up, cause the kernel does not seem to recognize it. I'm using an older kernel now, will still the info be valuable with an older kernel???...

This was what I could get from the New Version of the Kernel and the debug of the gnome-power-manager offline and not using the Internet, Thi8s one is for the right version of kernel 2.6.32-10 in Lucid...I hope this works.

Although this pertains to gnnome-power, I fixed wake-after-sleep issue by changing my display driver for AMD A8-GPU from recommended selection "xserver-xorg-video-ati" to "fglrx". In one of the forums someone suggested to look up log and look for "fail". I found it in KSystemLog's X-org log, a fail message upon calling "fglrx". So I changed the driver as I mentione before. And now the display wakes up with the computer when it wakes from the sleep. Hope this layman's explanation helps.
