[Bug 1411300] [NEW] Radeon flickering line after sleep
You have been subscribed to a public bug: Since Ubuntu 14.10, no matter what DE or version of Ubuntu (Xubuntu, Kubuntu), after sleep there is a flickering line at the bottom of my screen. For Kubuntu, it can be prevented by simply requiring a password after resume. For Unity, running "unity --replace" works as a workaround, and for Xubuntu, it's random as to whatever fixes it or not. It has been an annoyance, but I don't want to go back to an earlier version of Ubuntu, as the Radeon driver in 14.10, actually now allows me to use WebGL in Chrome, and things like Google Maps.. (it was a big problem as the previous radeon driver had a lot of bugs on this GPU, most of which were in fact fixed). I also can't use FGLRX, because for whatever reason, it is actually slower than Ubuntu 14.10's included open source driver (weird, I know, right?) The driver is generally perfect, except this problem with the flickering line. I am using the VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series]. Please assist, because this is a laptop, and can't just change graphics cards (I would if it was the solution though), and well, hitting hard times, so switching laptops isn't a choice. Besides, it's only 3 years old and still does everything I need done. I made a video demonstrating the flickering line at the bottom of the screen on resume from sleep. Sometimes videos explain things better than words: https://www.youtube.com/watch?v=V-t3K95g898 I would also like to add that I have completely reformatted the hard drive and reinstalled many other versions of Ubuntu, to find that 14.10 literally is the only one having this issue.
