So I’ve been tearing my hair out for quite a while now after Debian changed from sysv to systemd as the init system.<\/p>\n
After some update or other, my laptop’s internal mouse and keyboard would not work under X. In a terminal they worked fine, as did external USB devices. This breakage took a while to track down to Debian having installed systemd automatically. I “fixed” this by reverting to sysv.<\/p>\n
However, under sysv init, KDE’s Dolphin could no longer mount devices; permission errors. I tried many solutions to fix this all to no avail (*). Using udiskctrl I could mount devices manually, but that’s a bit of a pain. Clearly I needed to move to systemd, where the permission problems did not exist.<\/p>\n
After various online searches I finally hit on the real culprit: I had mounted \/var\/run and \/var\/lock as tmpfs to save the SSD on my new laptop, many moons ago. At some point, Debian changed these directories to be symlinks to locations which are already tmpfs-mounts, and hence my local manual configuration overrode those mounts, breaking systemd in various interesting ways.<\/p>\n
The following bug-report finally got me on the right tracK:
\nhttps:\/\/bugs.debian.org\/cgi-bin\/bugreport.cgi?bug=761076<\/p>\n
So I removed the offending lines in \/etc\/fstab, rebooted, and systemd is happy.<\/p>\n
Search Terms:
\n“Failed to get D-Bus connection”
\n“Failed to get D-Bus connection: No such file or directory”
\n“systemd laptop keyboard not working”
\n“systemd-journald: Received SIGTERM from PID 1 (systemd)”<\/p>\n
(*)UPDATE: this is a separate issue; yet to be resolved. I thought this worked when I booted under systemd, but it doesn’t.<\/p>\n","protected":false},"excerpt":{"rendered":"
