Success, part II: When attempting a Wayland session, the relevant syslog section grew from 107 lines to 396 lines. 'gnome-shell' messages are gone, it looks like a session gets actually started. And then there are now a lot of messages like this one:
Oct 31 18:08:01 piccard gnome-screensav[2194]: Anzeige kann nicht geöffnet werden: Oct 31 18:08:01 piccard org.gnome.SettingsDaemon.Power.desktop[2208]: Anzeige kann nicht geöffnet werden: Oct 31 18:08:01 piccard org.gnome.SettingsDaemon.Clipboard.desktop[2242]: Anzeige kann nicht geöffnet werden: "Anzeige kann nicht geöffnet werden" = "can't open display". So far no idea how this display should be set/activated/opened. ** Attachment added: "GDM-debug-shader-code-removed" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1727356/+attachment/5001320/+files/GDM-debug-shader-code-removed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1727356 Title: Wayland does not start up on "Integrated Graphics Chipset: Intel(R) G33": Shader compilation failed To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1727356/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
