I think I have the same issue. Difference is that everything worked as charm until I've updated some non-nvidia packages. Since then I'm stuck to uning nouveau as none of the workarounds worked.
HW: ROG STRIX GL503VM-FY022 nVIDIA GeForce GTX 1060 6GB What worked fine before update: kernel 4.15.x-x with nvidia 390 (ubuntu repository) kernel 4.17.x with nvidia 396 (ppa) After the update it worked one more time with 4.15.x with options nvidia_390_drm modeset=1 in /etc/modprobe.d/xxxx.conf Since after next reboot nothing has worked except purge-ing nvidia and switching to nouveau... Attaching apt log for that update. mono was updated as well adding a lot of noise, but the relevant part seems to be grub: Kibontás előkészítése: .../14-grub-efi-amd64_2.02-2ubuntu8.2_amd64.deb ... Kibontás: grub-efi-amd64 (2.02-2ubuntu8.2) e helyett: 2.02-2ubuntu8.1 ... Kibontás előkészítése: .../15-grub2-common_2.02-2ubuntu8.2_amd64.deb ...

Kibontás: grub-common (2.02-2ubuntu8.2) e helyett: 2.02-2ubuntu8.1 ... i.e. grub was updated from 2.02-2ubuntu8.1 to 2.02-2ubuntu8.2. Not sure if any of these can help, but for me nvidia has been completely broken since this update. Since then I'm constantly getting the following lines in kern.log (egrep -i '(nvidia|nvrm)'): kernel: [ 1.675561] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 396.24.10 Tue Jul 10 10:00:18 PDT 2018 (using threaded interrupts) kernel: [ 1.682807] nvidia-modeset: Loading NVIDIA Kernel Mode Setting Driver for UNIX platforms 396.24.10 Tue Jul 10 08:53:56 PDT 2018 kernel: [ 1.685191] [drm] [nvidia-drm] [GPU ID 0x00000100] Loading driver kernel: [ 2.543799] nvidia-modeset: Allocated GPU:0 (GPU-ca4d2121-189c-752b-9cba-302ed81038d4) @ PCI:0000:01:00.0 kernel: [ 2.595623] [drm] Initialized nvidia-drm 0.0.0 20160202 for 0000:01:00.0 on minor 0 kernel: [ 3.244611] nvidia-uvm: Loaded the UVM driver in 8 mode, major device number 236 kernel: [ 5.310256] NVRM: GPU at PCI:0000:01:00: GPU-ca4d2121-189c-752b-9cba-302ed81038d4 kernel: [ 5.310259] NVRM: Xid (PCI:0000:01:00): 61, 0ac0(2f10) 00000000 00000000 kernel: [ 12.366052] nvidia-modeset: WARNING: GPU:0: Lost display notification (0:0x00000000); continuing. kernel: [ 15.124364] nvidia-modeset: ERROR: GPU:0: Idling display engine timed out: 0x0000987d:0:0 ** Attachment added: "apt-2018-07-28-filtered.log" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1752053/+attachment/5169445/+files/apt-2018-07-28-filtered.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1752053 Title: nvidia-390 fails to boot graphical display Status in mesa package in Ubuntu: Fix Released Status in nvidia-graphics-drivers-390 package in Ubuntu: Fix Released Status in xserver-xorg-video-nouveau package in Ubuntu: Invalid Bug description: I'm using Bionic with the new 4.15 kernel.
