I have this same problem. I have a ATI Mobility Radeon 9600 M10 (RV350) and an AMD Athlon64 3000+ cpu. I've tried both the radeon and fglrx drivers and neither seem to work - it's the same scenario as above: when I hit "hibernate", the machine seems to shut down fine, starts back up, but when it gets to X it hangs, with a garbled screen similar to this: http://beework.isgreat.org/var/log/screenshot.JPG (from bug #72417, which may be a duplicate).
Also, if I hibernate from the console, it resumes fine, but once I switch back to X, i get a screen like above and the system is hung. I'm not sure what further steps to take to debug this. Thanks. -- 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
