Public bug reported: Unsure what causes this, but noticed a couple of issues recently that cause temporary or persistent GUI lockups. I can usually get to a different TTY to look at whats going on and find log entries like below in the syslog. They often seem to occur in batches. So far most times the UI will return to a functional state eventually (sometimes moments, other times minutes).
Let me know if/what else is needed to diagnose etc. drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in dpll_hw_state.wrpll (expected 0xb0210614, found 0x00000000) ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: xorg 1:7.7+7ubuntu4 ProcVersionSignature: Ubuntu 4.2.0-36.42-generic 4.2.8-ckt8 Uname: Linux 4.2.0-36-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 BootLog: * Setting up X socket directories...
