Testing upstream kernel, I can tell this situation is not a Ubuntu kernel specific issue. I can reproduce using upstream kernel.
This is where I'm at the moment: BAD kernel : v4.16.18 GOOD kernel : v4.17-rc1 Leaving us to the following 'vmwgfx' commits to bisect: ---------------- $ git log --oneline v4.16.18..v4.17-rc1 --grep="drm/vmwgfx:" ---------------- 320b164abb32 Merge tag 'drm-for-v4.17' of git://people.freedesktop.org/~airlied/linux 2a2553cc45c8 Merge branch 'vmwgfx-next' of git://people.freedesktop.org/~thomash/linux into drm-next 43bfefedd028 drm/vmwgfx: Bump version patchlevel and date 37efe80ce85f drm/vmwgfx: use monotonic event timestamps 20fb5a635a0c drm/vmwgfx: Unpin the screen object backup buffer when not used 89dc15b76fd3 drm/vmwgfx: Stricter count of legacy surface device resources 6073a09210e0 drm/vmwgfx: Use kasprintf 4e3e733b45df drm/vmwgfx: Get rid of the device-private suspended member c3b9b1657344 drm/vmwgfx: Improve on hibernation bf833fd36f9b drm/vmwgfx: Avoid pinning fbdev framebuffers dc366364c4ef drm/vmwgfx: Fix multiple command buffer context use ef86cfee7d74 drm/vmwgfx: Use the cpu blit utility for framebuffer to screen target blits 79273e1b7eb0 drm/vmwgfx: Add a cpu blit utility that can be used for page-backed bos 25db875401c8 drm/vmwgfx: Cursor update fixes 904efd9e3f4c drm/vmwgfx: Send the correct nonblock option for atomic_commit ac3069e67f56 drm/vmwgfx: Move the stdu vblank event to atomic function aa64b3f18aeb drm/vmwgfx: Move screen object page flip to atomic function 3cbe87fcf026 drm/vmwgfx: Remove drm_crtc_arm_vblank_event from atomic flush 4e2f9fa7ffb5 drm/vmwgfx: Move surface copy cmd to atomic function 91e9f352cd1b drm/vmwgfx: Avoid iterating over display unit if crtc is available 25a28906ebee drm/vmwgfx: replace drm_*_unreference with drm_*_put 4f4becef17d6 drm/vmwgfx: Use drm_mode_get_hv_timing() to populate plane clip rectangle ---------------- As I said, I'll start the bisection on Monday. My first feeling about the potential good candidate assumption was wrong but with recent testing, we now know the fix is amongst the commits listed above ^ - Eric -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1832138 Title: Login screen never appears on vmwgfx but setting WaylandEnable=false fixes it Status in linux package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Invalid Status in mutter source package in Bionic: Incomplete Status in mutter source package in Eoan: Invalid Bug description: I'm running Ubuntu 18.04.2 desktop in a virtual machine under VMWare Fusion Pro V11.1.0 on MacOS Mojave 10.14.5, all on a 15inch 2018 Macbook Pro. I've been running this Ubuntu 18.04.2 VM without problem for many months without problem. Yesterday, I did 'sudo apt update; sudo apt upgrade'. Upon rebooting, the system hangs immediately after displaying the splash screen. I never see a login screen. And I can't use Ctrl+Alt+F2 to navigate to a console/tty login. I can SSH into the system however. I've found that I can work around the hang/freeze if I uncomment the following line in /etc/gdm3/custom.conf; #WaylandEnable=false After uncommenting the WaylandEnable=false line and rebooting, then I see the login prompt as expected and I can then log in and use the system normally again. After the 'apt upgrade' my system is running linux kernel 4.15.0-51, as shown in this 'uname -a' output; Linux ubuntuvm1 4.15.0-51-generic #55-Ubuntu SMP Wed May 15 14:27:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux lsb_release -a output; No LSB modules are available.
