Thanks a million for your tests and comment, R.Ruback. This is one the most annoying bugs for me currently. Looking for differences between your and my setup. I found in /etc/default/acpi-support
USE_DPMS=true HIBERNATE_MODE=shutdown and RADEON_LIGHT=true (commented out on my machine) I believe I have never touched this file, so that should be what is shipped. AFAIK, xorg.conf is not needed anymore for recent xorg. Can you try with an empty xorg.conf or move it out of the way? I will also try and do some tests with your changes and report back. -- [M6 LY] System lockup when switching VT's or Resume from Suspend https://bugs.launchpad.net/bugs/148408 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
