Shortly after my original post, I reinstalled Ubuntu because I could not figure out how to remove the proprietary video driver that may have contributed to the problem. Indeed, I was then able to get my video display to work again.
But, about 3 or 4 months ago I ran into a blink blank problem and posted a new bug that may be related to this one: Bug #1044885. I posted this comment on Bug #1044885: 1. My PC's mother board has an ATI Radeon graphics chip. It blinked and blanked only when it recognized the monitor as a Dell 17". It did not blank when it recognized the monitor as Unknown. This happened occasionally after an update/upgrade. When that happened, I resisted updates. But, Ubuntu was smarter and would "upgrade" spontaneously. 2. In the belief that I might have a h/w problem, I added a new grapcs card: Zotac Nvidia GeForce GTX. The blinky blank problem became more pronounced and my on-board graphics ceased to provide VGA output. 3. I have replaced my Dell 17" monitor by my wife's LG monitor which is recognized by Linux as a Goldstar Company Ltd 23", 1920 x 1080 dispaly (VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2)). The blinky blank problem is as bad as with the Dell 17" monitor. The problem is: - not the monitor - not the graphics hardware - not Ubuntu, as it seems I am the only person with this problem I am at a loss. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/922733 Title: Inappropriate response to GFX card problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/922733/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
