This bug is still present in Ubuntu 13.10. I perceive the flicker to include a beating effect which moves as waves from bottom to top of the screen.
The screen flicker can also be seen in BIOS and in any operating system with a generic graphics driver loaded. However, when the Intel 4500MHD driver for Windows is started, it sets some parameters which makes the flicker effect disappear. Under Linux, the flicker effect remains even with the proper Intel graphics driver. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/581076 Title: [gm45] HP Compaq 2230s laptop: Screen flickers when screen brightness dimmed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/581076/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
