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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
