try linux-oem -1035 from bionic-proposed, it has ~50 commits backported from 5.0 to i915 driver which should help with these issues
** Description changed: I have two connected external monitors. They are connected through a Dell Dock W15. One is connected with VGA, the other with DP. Sometimes the VGA monitor complains about the resolution and will not work after the screen saver has been active (and putting the monitors to sleep). When shutting down the system, it then hangs and I have to force a shutdown with the power button. There seems to be a kernel crash before as seen in the dmesg log. + + + ProblemType: Bug + DistroRelease: Ubuntu 18.04 + Package: xorg 1:7.7+19ubuntu7.1 + ProcVersionSignature: Ubuntu 4.15.0-1034.39-oem 4.15.18 + Uname: Linux 4.15.0-1034-oem x86_64 + ApportVersion: 2.20.9-0ubuntu7.6 + Architecture: amd64 + BootLog: Error: [Errno 13] Åtkomst nekas: '/var/log/boot.log' + CompositorRunning: None + CurrentDesktop: ubuntu:GNOME + Date: Thu Mar 28 12:04:07 2019 + DistUpgraded: Fresh install + DistributionChannelDescriptor: + # This is the distribution channel descriptor for the OEM CDs + # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor + canonical-oem-somerville-bionic-amd64-20180608-47+italia-whl+X31 + DistroCodename: bionic + DistroVariant: ubuntu + DkmsStatus: virtualbox, 5.2.18, 4.15.0-1034-oem, x86_64: installed + ExtraDebuggingInterest: Yes + GraphicsCard: + Intel Corporation Device [8086:3ea0] (prog-if 00 [VGA controller]) + Subsystem: Dell Device [1028:08af] + InstallationDate: Installed on 2019-02-12 (44 days ago) + InstallationMedia: Ubuntu 18.04 "Bionic" - Build amd64 LIVE Binary 20180608-09:38 + MachineType: Dell Inc.
