Thanks for the bug report. It seems unlikely the flicker is caused by the new CPU. To prove that you could maybe reinstall the old one?
I think more likely this is a connection problem with the analog VGA cable. Try unplugging and replugging both ends of the VGA cable. And if you can then please try a different VGA cable. If that doesn't resolve the problem then please attach a photo or video of the problem. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- 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/1960410 Title: desktop always flicking after i update processor to i7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1960410/+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
