Thank you for your responses, and I apologize if I sounded rude - I didn't meant to.
I rebooted in the hybrid mode and added the abovementioned lines into /etc/environment, unfortunately the /tmp/mutterlogs file is not created. There are other files though: $ ls -la /tmp/mutter* -rw------- 1 gdm gdm 468 okt 19 12:12 /tmp/mutter-1444-debug-log-BN1E8Y -rw------- 1 gdm gdm 77041 okt 19 12:12 /tmp/mutter-1521-debug-log-XFRL8Y -rw------- 1 mavi mavi 493891 okt 19 12:15 /tmp/mutter-1931-debug-log-POR97Y I'm not sure if they would be helpful to you. I have verified that the env variables are indeed set: $ echo $WAYLAND_DEBUG 1 I wondered that the file might be deleted by the auto-cleanup of /tmp, so I created world-writable /foo directory and set MUTTER_USE_LOGFILE=/foo/mutterlogs but nothing got created in /foo. Please let me know if you'd need the contents of those files. Yet they contain nothing wayland-specific: $ sudo cat /tmp/mutter* |grep -i wayl VERBOSE: Using _NET_WM_NAME for new title of 0x3a00001 (Bug #17245): "Bug #1724583 “gdm3 in Ubuntu 17.10 doesn't list wayland sessions...” : Bugs : gdm3 package : Ubuntu - Chromium" VERBOSE: Ignoring WM_NAME "Bug #1724583 “gdm3 in Ubuntu 17.10 doesn't list wayland sessions...” : Bugs : gdm3 package : Ubuntu - Chromium" as _NET_WM_NAME is set cat of the first file: $ sudo cat /tmp/mutter-1444-debug-log-BN1E8Y VERBOSE: Mutter version 3.26.1 running on 19.10.2017 VERBOSE: Running in locale "LC_CTYPE=en_US.UTF-8;LC_NUMERIC=sk_SK.UTF-8;LC_TIME=sk_SK.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=sk_SK.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=sk_SK.UTF-8;LC_NAME=sk_SK.UTF-8;LC_ADDRESS=sk_SK.UTF-8;LC_TELEPHONE=sk_SK.UTF-8;LC_MEASUREMENT=sk_SK.UTF-8;LC_IDENTIFICATION=sk_SK.UTF-8" with encoding "UTF-8" VERBOSE: Compiled with randr extension VERBOSE: Compiled with startup notification Perhaps it is as you say - GDM3 sees two graphic cards, assumes hybrid mode and simply disables Wayland right off the bat; perhaps we will need to wait until Mutter 3.27.1 is released. I was probably wrong: those two cards are not completely separate but need to cooperate somehow (since Intel's connected to the panel while Nvidia's connected to HDMI), and perhaps Mutter needs to do some magic to support that?
