7/13/2018 - comet2 machine arrives in bldg 48 rm 248. Kerberos authentication (temporary). Initial pass at identifying and installing needed software packages (above table) 8/28/2018 - comet2 rebuilt, lose login ability 9/28/2018 - regain ability to login via local account. Re-install needed packages. Also move offending file which causes polkitd to consume too much CPU, "A workaround that I've been using is to remove /etc/xdg/autostart/org.gnome.SettingsDaemon.Account.desktop until the above mentioned bug is fixed." (but this does not clear up the issue - polkitd still consumes 7-6% of the CPU continuously) 11/13/2018 - chef client installed (by Karl). Unexpectedly (to TG), this also activated unix kerberos authentication, thus I begin to use the 'dragon' (SLAC) account in favor of the dragon1 (local) account on comet2. 12/17/2018 - Karl adds 'dragon1' and 'dragon' accounts to /etc/group 'wheel' group. This allows a user to run, for example, the software installation tool GUI launched from the Applications -> System Tools menu in the WM. 12/19/2018 - Karl adds 'dragon' to sudo list. |
Tips and Tricks
Code Block The GUI Gnomes settings app does not provide full flexibility to access and set its parameters. For example, the "Power" section allows one to select a idle time before the screen blanks, but is limited to choices between 1 and 15 minutes. To set this value to 1 hour, the following command works: gsettings set org.gnome.desktop.session idle-delay 3600
