The fix I posted in #34 above, did not work consistently. I have installed the ati and radeon drive from Jaunty. I can now suspend perfectly. So this bug really applied to a version of the ATI driver that is above the one released in Jaunty. -- screen backlight off after resume-from-suspend when using ATI KMS https://bugs.launchpad.net/bugs/434956 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

It seems I can now successfully suspend, at least 5 times so far and resume properly, using the following parameters: Kernel from mainline - 2.6.32-rc7, using parameter modeset=0 and The ATI driver only from the following PPA https://launchpad.net/~xorg-edgers/+...e/drivers-only While this has worked for my HP DV8040, with ATI 200m Video card RS480 5955, I do not know if this works for you. -- screen backlight off after resume-from-suspend when using ATI KMS https://bugs.launchpad.net/bugs/434956 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
