I am experiencing the exact same problem on my Lenovo Thinkpad W500. My video card is the ATI Mobility Radeon HD 3650 hardware, however. I am also getting white (frequent but not constant) horizontal lines appearing and disappearing randomly all over the display.
I'm guessing this could be a Linux Kernel (KMS) problem, or an X-org problem, or a video driver problem. I will hold off on attaching a massive amount of log data and hardware info someone with a little more knowledge in these areas can tell me what would be most useful. :) I can provide a video of this problem if it would help troubleshoot. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Confirmed -- Problem with X in Lucid on Lenovo T500 https://bugs.launchpad.net/bugs/538648 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
