    Hello

     

    I face a problem that when I use ubuntu 1404 Kernel 3.19 in my tablet which is  Bay trail platform, the panel can't display when  suspend resume.

     

    I try to contact an external panel and it can show up, only the tablet panel can't display until I reboot the system.

     

    And I also found this issue cause the BIOS video setting is Legacy  mode, it will be OK when I change to UEFI mode.

     

    But this problem would not happened in Windows OS no matter Legacy or UEFI mode, so I think must something wrong in the driver.

     

    As my driver is i915, could you please help me to check where is the problem?

    thank you~!!
