Hi, I have a fedora21 box and periodically the display stops responding. The display on the monitor is blank, and trying to wake it again with the mouse or keyboard is not successful. I can VNC into the system, and while the screensaver is on with the clock in the center, the clock does continue to update. It's like my keystrokes aren't being acknowledged, I'd say. I can access the system remotely via ssh. I've tried killing Xorg, but nothing changes. It just comes back in this screensaver mode and the monitor is still unresponsive. I'm using the default driver that's chosen at install time for an ATI Radeon chipset. I've looked through the Xorg.9.log file and there is nothing indicating any type of helpful error message. How can I troubleshoot this further? Perhaps it's a known problem?
Uhm, are you certain it's just the screensaver or could it be the machine is going into suspend or sleep state? In some cases, sleep or suspend also powers down the USB ports. If you're using USB keyboards or mice, that could prevent the items being seen. This can be disabled. The shotgun approach is, as root: for i in /sys/bus/usb/devices/*/power/autosuspend; do echo 2 > $i; done This would turn off autosuspend for all USB devices. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - Give me ambiguity or give me something else! - ---------------------------------------------------------------------- -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
