Hi, thank you for checking logs.
Chrome and X display server come from Chromium plugin:
I’m not aware of installing MESA drivers. It may come with other package.
There shouldn’t be any other automount deamon. I’ve added USB disk to fstab to make it available at boot time:
osmc@osmc:~$ cat /etc/fstab
/dev/mmcblk0p1 /boot vfat defaults,noatime,noauto,x-systemd.automount 0 0
UUID=“95e13a90-40c4-4f8a-b19c-efc20f1f2f51” /mnt/data ext4 defaults,nofail,noatime 0 0
There is no PulseAudio right now. I’ve removed it few minutes after installing it. (Trying to make bluetooth keybord connection persistent. It didn’t help. I managed it later without PulseAudio lib.)
I would rather not reinstall OSMC. 
I’ve put to much work into system.
