Will not recover from suspend or hibernate

> upgraded from 10.10 to 11.10.

If this is true report a bug, it's in developement status.

If Natty 11.04 was meant it's maybe a graphic card issue.
Suspend issues are tricky.

With no further info do a websearch with keywords ubuntu <graphic card> suspend.
Or have a look at Bug reports around 700000.

You are probably right about the graphics card. When I first downloaded natty I was unable to utilize unity so I downloaded nvidia173 that did the trick but that is when the recovery problem began. I hate to say that my skill level is so low that most of what is on those canonical sites is greek to me. Oh by the way, you're absolutely right it is 11.04. I just had a senior moment there. If necessary I can just let my computer run all day. Thanks for your help.

If it worked well with Maverick and not anymore with Natty consider to report a bug.

I've located a possible glitch in the Nvidia driver. It has Nvidia173 and a Nvidia accelorated driver. At the bottom it has Nvidia172 installed but not activated and a square to click to activate. It also has Nvidia accelorated driver not installed. I'm at the point on the learning curve where I'm hesitant to click anything I don't fully understand. What do you think? I've been trying for two days to figure out how to file a bug report.

correction: it says Nvidia173 installed but not activated. Sorry.

Is nvidia-current and nvidia-settings installed?

Usefulness of -173 depends which graphic card you have.
http://packages.ubuntu.com/natty/nvidia-173

Drivers can be activated in 'additional drivers' in system settings.

Please open a terminal and post outputs: ctrl+alt+t
sudo lshw -C video

dpkg -l nvidia* |grep ii

Lets say for example nvidia-173 causes trouble:

## Basically it's: ubuntu-bug <package_name>

I have the same problem: system is not recovering from suspend mode: "the screen is filled with disjointed pixels". 10.10 worked fine. System is a HP DV6

Does this help?

John, I downloaded NVIDIA 173 from their download site and activated it on the download site. I now have a screensaver when it returns from suspense but theutilities at the side and the toolbar are blurred and unreadable. Fortuately I know what the tools are but it is irritating. I did report a bug and have received no answer. Good luck.
