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.
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 Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1044885 Title: blinking blanking monitor Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: lsb_release -rd on AMD 64bit PC with apt-cache policy pkgname N: Unable to locate package pkgname My display sometimes comes up as Dell 17" 1289 x 1024 and sometimes, after an update, as Unknown 1200 x 800. In the Dell Case there are lower resolution options that also display the blanking behaviour. In the Unknown case, there is no other option. When the Display comes up as Dell, it randomly blanks outfor usually short (< 1 min) random periods. When the display comes up as Unknown, it dos never blanks out, except to sleep.
