It might be a separate issue, but since this one was reopened and not yet closed, I just decided to follow up. My laptop decided to reboot this night and I booted into a barely usable desktop -- besides changed behaviors I have massive slowdowns: since every glitch (2 second switching between virtual screens or even tabs within urxvt) is accompanied by those logs in the journal, I think it is related. I would really appreciate if Debian Gnome gurus drilled down this one. Meanwhile I might just give a shot to that not yet merged https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/4
a complete journal dump for this boot is available from http://www.onerussian.com/tmp/journal.20180320.txt I have $> acpolicy gnome-shell gjs gnome-shell: Installed: 3.28.0-1 Candidate: 3.28.0-1 Version table: *** 3.28.0-1 600 600 http://http.debian.net/debian sid/main amd64 Packages 100 /var/lib/dpkg/status 3.22.3-3 100 100 http://http.debian.net/debian stretch/main amd64 Packages gjs: Installed: 1.52.0-1 Candidate: 1.52.0-1 Version table: *** 1.52.0-1 600 600 http://http.debian.net/debian sid/main amd64 Packages 100 /var/lib/dpkg/status 1.46.0-1+b2 100 100 http://http.debian.net/debian stretch/main amd64 Packages thank you in advance -- Yaroslav O.
