  • Hello everybody,

      I'm posting for the first time so sorry for anything I could miss.

    I'm running Ubuntu 14.04 on a Lenovo R61i with integrated graphics GM965/GL960. After a suspend/resume cycle my screen is trying to resize to double width, letting me see only half screen, every few minutes, causing a CRTC 64 Error window to show up. Closing that window I get back to normal view. Looking around in the kernel log I discovered this line:

    May 19 21:41:16 ThinkPad-R61i kernel: [  713.736427] [drm] HPD interrupt storm detected on connector VGA-1: switching from hotplug detection to polling

     

    And after that a sequence of:

    May 19 21:41:16 ThinkPad-R61i colord: Device added: xrandr-VGA1
    May 19 21:41:16 ThinkPad-R61i colord: device removed: xrandr-VGA1

     

    So I'm guessing there must be a problem with the VGA connector kind of detecting something which is not actually plugged, but I really cannot understand anything more than this.

    Is this problem anyhow solvable? It is actually very annoying, since I suspend the laptop very often, so any help will be appreciated. Obviously I can give you any information you need if I'm able to gather it. Thank you!
