Ubuntu 10.10 crahes while activating standby mode

[Ettore Atalan]

Hi

Standby mode was working properly on my notebook (Lenovo SL500) running Ubuntu Lucid, but after upgrading to Maverick it doesn't work any longer. After activating standby mode, only the screen gets dark (LCD background light still on) and that's it. Ubuntu is frozen and doesn't react on any key pressed or mouse moved.

I have no idea what's going wrong with Maverick.

Can you take a look at the settings in System- preference - screensaver - power manager

[Ettore Atalan (atalanttore)]

Yes, of course.

Had the same issue with my SL500 as well. Resolved itself today after updating my OS. I don't know what caused it, but... actually I'm okay with it gone. :-)

Well, on my SL500, none of the maverick kernels 2.6.35-22-generic to 2.6.35-28-generic resolved the problem. When it fails, it locks up and eventually the fan starts going full throttle. After sitting like that for a while (possibly overnight), it often has to be hard powered off before turning back on. I assume the system is overheating at that point.

About a week ago I installed the lucid-updates kernel 2.6.32-30-generic , and I've not seen the issue since.

Ettore Atalan, thank you for reporting this bug to Ubuntu. Maverick reached EOL on April 10, 2012.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases

Is this an issue in a supported release? If so, could you please execute the following command, as it will automatically gather debugging information, in a terminal:
apport-collect 670092

[Ettore Atalan (atalanttore)]

Nice to get a response after 4 years.

In the meanwhile I have bought a Samsung notebook. I don't know if this bug is still present in a supported release, because my old notebook is broken since 2012.
