You have been subscribed to a public bug: I noticed this problem after I corrected the system clock from another OS (fixing the time on any of my OSs causes the others to display an incorrect time...). Ordinarily Ubuntu 16.04 starts in about 30 seconds on my system and displays the splash screen during early initialization. When the system clock is wrong, the splash screen is not displayed and the system takes about 5 minutes to start.
Additionally, when the screen saver is on, it takes about 5 minutes from moving the mouse for the screens to turn on (there are two, if that matters) I think this is related to libdrm-amdgpu1 because dmesg gives me hundreds of messages looking like: [ 308.832210] Failed to send Message. [ 309.230389] Failed to send Previous Message. These messages originate from a drm source file: https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/amd/powerplay/smumgr/tonga_smumgr.c (There's another amdgpu file with the same messages but my GPU is tonga architecture) I'm not entirely sure that the system clock is responsible but this seems to be an intermittent problem and I haven't noticed any other contributing factors. $ lsb_release -rd Description: Ubuntu Xenial Xerus (development branch) Release: 16.04 $ apt-cache policy libdrm-amdgpu1 libdrm-amdgpu1: Installed: 2.4.67-1 Candidate: 2.4.67-1 Version table: *** 2.4.67-1 500 500 http://ca.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: libdrm-amdgpu1 2.4.67-1 ProcVersionSignature: Ubuntu 4.4.0-18.34-generic 4.4.6 Uname: Linux 4.4.0-18-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.20.1-0ubuntu1 Architecture: amd64 BootLog: CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Tue Apr 12 11:33:56 2016 Dependencies: gcc-6-base 6-20160405-0ubuntu2 libc6 2.23-0ubuntu2 libdrm2 2.4.67-1 libgcc1 1:6-20160405-0ubuntu2 DistUpgraded: Fresh install DistroCodename: xenial DistroVariant: ubuntu GraphicsCard: Advanced Micro Devices, Inc.
