Thanks, that's a nicely detailed bug report. The first issue you identified is just that your Intel GPU is too new for Linux kernel 4.13 so you need to set alpha_support=1. This will be fixed in Linux kernel 4.15 (coming in Ubuntu 18.04).
The second issue you describe is bug 1724732. So let's keep this bug just about the first issue. ** Summary changed: - integrated intel GPU doesn't work with wayland on ubuntu 17.10 + Intel Coffee Lake GPU isn't supported by default (yet) ** Package changed: weston (Ubuntu) => linux (Ubuntu) ** No longer affects: wayland (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to wayland in Ubuntu. https://bugs.launchpad.net/bugs/1728313 Title: Intel Coffee Lake GPU isn't supported by default (yet) Status in linux package in Ubuntu: New Bug description: I've got a CPU with integrated GPU, it's the intel i5-8400; I've also installed an old asus [Radeon HD 6670/7670] GPU. OS: ubuntu 17.10 The first problem is that the integrated GPU doesn't work unless you edit grub enabling the i915 driver support. I had to modify GRUB to load the intel driver: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.alpha_support=1" This GPU works perfectly with wayland (gnome and ubuntu session): Turks XT [Radeon HD 6670/7670] But when I enable the integrated GPU (by disabling the Radeon pci GPU from the bios), I can't use wayland, which disappears from the login screen. My question is why the integrated intel GPU doesn't work with wayland: I can only use X. If I switch from gdm3 to lightdm, I can see the wayland gnome and ubuntu sessions in the list of the available sessions, but I can't login. To be precise, using lightdm I can't login at all. When logging, there are some errors, for example: [OK] Starting session manager for UID 121 Stopping session manager for UID 121 ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: weston (not installed) ProcVersionSignature: Ubuntu 4.13.0-16.19-generic 4.13.4 Uname: Linux 4.13.0-16-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.1 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: GNOME Date: Sun Oct 29 00:22:36 2017 DistUpgraded: Fresh install DistroCodename: artful DistroVariant: ubuntu GraphicsCard: Intel Corporation Device [8086:3e92] (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
