Title:
Screen Flickering and display problems
Status in “xorg” package in Ubuntu:
Confirmed
Bug description:
On doing a fresh install of Ubuntu 13.10 on a system which previously
had 12.04, using a USB stick, I booted my HP ProBook 445 laptop (AMD
A6-5350 chip with Radeon HD Graphics) to find that some launcher icons
were flashing on and off, and the screen generally seemed to be
flickering, with the icons in the system tray and the launcher
blinking. The system itself was working fast, but there seemed to be
something wrong with the display. A couple of minutes after it booted
completely, the Update Manager started up, but its windows were
flickering, and it was difficult to read text written inside the
window. After it completed updating, i rebooted the laptop, and things
seemed to flickering less than earlier. So i thought i'd open a simple
application, like Files, and see if the display was still awry. It
still was. I could see occassional streaks and dark lines across the
screen, and the display seemed to have some serious internal error. A
long press of the Super Key opens the Unity help window, as we know,
and when i long-pressed the Super Key, the screen starting behaving
weird, with text and icons disappearing and reappearing randomly
across the screen. It definitely wasn't fun to see, and it definitely
didn't seem like everything was fine. It was just not what one would
expect off a fresh install of the latest Ubuntu OS.
I cannot attach screenshots, because whenever i try to take
screenshots of a weird looking screen, the screenshot is either never
taken, or if taken, everything looks perfect in the picture.
The result for apt-cache policy xorg is
