Hi after enabling Ubuntu default repos I have apt-get installed latest Catalyst Drivers.

Everything installed correctly with no problems.

However... Until I suspended... Then I try to resume and all I get is a black screen with light. So Suspension is not working anymore.

Any solutions to this problem for ATI Radeon 6250 would be appreciated thanks.

If you are using Unity, test suspend/resume under a different DE (Gnome, LXDE, etc.). I had the same issue on a laptop with RadeonHD 6650M, but was able to successfully suspend/resume as long as I was not using Unity. –  blasmat Aug 29 '12 at 18:57

This problem comes from flgrx driver. I had the same problem on my AO722 because I initially installed the flgrx graphic driver. As I did not know how to get rid of flgrx driver, I reinstalled Ubuntu 12.04 64 bit. This time I did not install the flgrx driver and kept the standard driver installed automatically by Ubuntu. Now suspend works perfectly.

This driver,while for embedded devices, fixed my hibernation issues with my AO722. Good Luck. http://www.phoronix.com/scan.php?page=news_item&px=MTE4NDk

I have the same netbook.

This is a known issue with Catalyst drivers. See this long discussion http://ubuntuforums.org/showthread.php?t=1811178 as well as this help page (it says AO522 but covers AO722 as well) https://help.ubuntu.com/community/AspireOne522#Suspend_and_Hibernate for more information.

Update:

This issue has been solved with Ubuntu 12.10 and later versions of Catalyst drivers. Ubuntu suspends and resumes without any problem with newer version flgrx drivers.
