If it's software at all then this would be a kernel bug. But I suspect the issue is more likely hardware since 1920x1080 @60Hz is pushing the limits of analog VGA. Anything less than a perfect cable with perfect connections and I'd expect display glitches like this.
Personally I'd recommend adding a graphics card to the machine so you can use HDMI on both monitors. But you might also want to try 30Hz to see if it makes the display more stable. We can also keep this open as a kernel bug just in case it is. ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Summary changed: - multiscreen one display goes black on resume + Analog VGA goes black on resume -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2049976 Title: Analog VGA goes black on resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2049976/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
