I am new to Ubuntu, so not sure of anything yet.
But after upgrading to 15.10 I get this error 'intel pipe config compare i915 error mismatch in ips_enabled' after I the grub screen when I load Ubuntu.
Any help would appreciated.

I have the same problem. Really annoyed and quite unhappy with myself for upgrading.– HarelOct 29, 2015 at 8:25

I ran into the same error. There are a couple of bug threads related to the errors I'm seeing and they claim to have fixed it in the nightly kernels.
dmesg shows "drm:gen8_irq_handler i915 ERROR The master control interrupt lied (SDE)!"
The key to solve this issue (at least for me) was to remove the usage of nomodeset from /etc/default/grub (requires to manually execute sudo update-grub afterwards to actually apply the change). Rebooting the Intel i915 driver load normally.
