[HD 4870] Power-off and power-on of monitors in multiheaded fglrx xorg configuration causes X freeze

Turned on screensaver and power management. Monitors go to sleep at the specified time, but do not come back up when activating mouse or keyboard. I assume because the input is not being passed to X. Pressing Caps Lock or Num Lock do not change the led indicators on the keyboard.

Thanks for the thorough report and helping make Ubuntu better!

Would you be able to attach the following files (after a hang-up):

 /var/log/Xorg.0.log

~/.xsession-errors

Sure. I am including my Xorg.0.log file. I'll also attach my xorg.conf file. However, I have discovered that when the GDM Login display is present, and I cycle the monitors, X does not freeze up. This leads me to believe that there is something running in my session that is causing this problem. I will also include a screen capture of the startup applications defined in gnome.

Ok, I disabled the power management app in the startup applications, rebooted the system, and tried again. Still having the same problem. I then rebooted, ran a ps -welf > pre-session-processes.list to output all the processes running during the GDM session before logging in. Then I logged in, and waited for all the default applications to start up that are included in the startup application list, and reran the ps command like so: ps -welf > post-session-processes.list.
I am attaching a diff of the two files: diff pre-session-processes.list post-session-processes.list
I hope this will help to narrow down the problem.

I've posted a new version of the -fglrx driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

Get fglrx 8.620 here:

  https://edge.launchpad.net/~xorg-edgers/+archive/ppa

Bryce, 8.620 does not resolve this particular issue. I see the same problem with the new driver. It does fix other problems, such as restarting X cleanly without power cycling the computer and xinerama. Please let me know if I can provide further assistance.
Thanks.

Thanks for testing, perhaps it will be fixed in a future -fglrx. Or on the off chance it's a kernel issue, it might be useful to test with a newer kernel, however from what you've described this sounds a lot like a GPU lockup, which is going to be a driver issue so we'd need to wait for a new driver.

no need to keep open for the xserver.

This issue is solved with the 8.632 build from ati. I ran the ati-driver-installer-9-4-x86.x86_64.run --buildpkg Ubuntu/jaunty
Build went fine, and I then installed the deb packages the installer generated.

I should also note that I am no longer using ndependent screens. I am using xinerama, and everything seems to be working ok with this configuration (not xgl which xinerama does not support). Thanks to everyone that has looked into this issue. My system is now usable again, and I have not noticed any issues with the new drivers for about a week now.

Ok, good to know. Karmic still has 8.620 though, so I won't close this just yet.

This bug was fixed in the package fglrx-installer - 2:8.632-0ubuntu1~bwh~1
