Title:
  can't use system with kernels newer than 1.13.x due to monitor
  resolution misfunction

Status in The Linux Lowlatency Kernel:
  Unknown
Status in “linux-lowlatency” package in Ubuntu:
  New

Bug description:
  i can use Linux 3.13.x kernel (im currently running 1.3.0-32 from
  Trusty while writing this). Once i upgraded to 1.14.x, and i couldnt
  use my PC. same symphtoms.

  it seems that kernel does not get monitor resolution properly, but im
  not good at coding, so i cant say what the reason is...

  Now, i have recently upgraded to Utopic, and i cant use 1.16.x kernels
  too.

  I have 2 laptops, and this desktop PC

  My laptops have an AMD Radeon HD 5143 and an AMD Radeon HD 8400
  (integrated into an AMD A6-5200 CPU). Both are working correctly.

  My desktop PC (the one that fails) uses an AMD Radeon HD6570 PCI-
  express, with an Intel Core i3-530

  Each computer uses the new 7.4.0 ati driver, so open source driver is not the problem.
