I'm afraid I was not able to test the latest upstream kernel. I could
boot, but after that I could only see the desktop and the pointer, but
no launcher nor the upper panel. TTY1 was just a horrible screen with
green stripes.

Title:
  Monitor configuration changing every few minutes after standby/resume

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  On a Lenovo R61i with integrated graphics Intel GM965/GL960, Ubuntu 14.04 64bit, after a standby/resume cycle, every few minutes the monitor resolution changes, stretching (horizontally) the desktop and the windows. The laptop monitor, therefore, only displays half desktop (the left one) with the windows and the desktop stretched. The panel and the launcher are ok, whereas the pointer moves within my monitor, but controlling the new resolution display, hence not pointing exactely to where it is, but to somewhere at its right! As soon as this happens, an error window pops up, saying "unable to change monitor configuration, due to CRTC 64". As I exit this window, everything returns normal. Switching to TTY1 and back to desktop, instead, does not fix it.
  To be precise this doesn't happen as soon as I wake up the laptop, but it occurs after some time it has been waken and then repeats every few minutes. It may also happen that, instead of all this, I only see my desktop rearranging things very quickly (less than 1 second) or just flashing and then returning to normal view.
  This bug was not present in Ubuntu 12.04 Precise, with the same hardware.

  Looking at the system logs I have found that what happens is that Xorg
  resizes the framebuffer as if it had to split the desktop between the
  laptop monitor and an external monitor, due to a VGA external monitor
  being detected.

  Temporary: screeshots will be soon attached.
