Uh... I had forgotten I had reported the problem here... just discovered it again.
I have both suspend&hibernate working with 2.6.15-27-k7 (not perfectly for hibernate : I have to switch back&forth from console before getting my screen back -- and it's not locked). Disabling DRI made it work. More recent kernels just don't work. -- No more X on resume after hibernate https://launchpad.net/bugs/23545 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
