Bryce, Thanks for the rapid response.
No, the system is about 4 years old now. I've installed many distro's on it in the past (#buntu's, openSUSE, Mandriva, PCLinuxOS, Fedora, Mint, Debian etc. etc.) and have never had this screen flicker before. It's the first time have tried Natty. Hope that helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/727979 Title: Screen flicker approx. every 30 seconds -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
