Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.16 kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

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.
