Hi there, I'm using a gentoo-guest inside a virtual box on a Win10 host. The last somewhat working combination was kernel 4.4.39/virtualbox-5.1.24.
When I update to kernel 4.12.12, the X-Server does not work anymore (I've also tried with 4.9.xx, same result -- no X) I used genkernel to compile the kernel, copied the previous 4.4.39-config from /proc/config.gz to /usr/src/linux-4.12.12-gentoo via zcat, and did no further changes; so nothing relevant should be changed, at least to my knowledge. After compilation of the kernel, required packages have been re-emerged: - app-emulation/virtualbox-guest-additions - x11-drivers/xf86-video-virtualbox Booting with 4.12.12: - sddm crashes with segfaults - Starting X from the command line: X complains missing EGL_MESA_drm EGL_MESA_drm_image required. : CommandLine Error: Option 'asan-instrument-assembly' registered more than once! LLVM ERROR: inconsistency in registered CommandLine options [???

The only thing that changed is a kernel upgrade and a rebuild of the virtual box modules. Any ideas? Thanks in advance, Alex
