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?
It would be best if you submit a bug report to the Ubuntu project or the Intel Kernel Graphics driver project for help with this issue. Please see https://01.org/linuxgraphics/forum/graphics-power-users/found-bug-do-not-report-it-here for more details.
