Vlad, Based on your various replies, my guess is that this is a kernel problem (esp. since it failed with GDM as well).
According to uname -a, you are running a generic kernel, but your chip is an Athlon 64. Have you tried installing and running an-AMD specific kernel? -- Uniwill 258KA doesn't resume after suspend/hibernation https://launchpad.net/bugs/72417 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
