An engineer's life around Kyoto

I have not paid a little effort on power-saving setting of my laptop machine, but I finally made it to some extent. After searching around the web pages, the article on the https://forums.bunsenlabs.org/viewtopic.php?id=1920 page reminded me of laptop-mode-tool package and tried it. At first, I installed laptop-mode-tool, rebooted and launched the powertop . The following screen capture is its screen: PowerTOP 2.6.1    Overview   Idle stats   Frequency stats   Device stats   Tunab >> Bad           Wireless Power Saving for interface wlan0                         Bad           Enable Audio codec power management    Bad           Enable SATA link powe...

I have been using MATE desktop environment on my laptop PC since my installation of Debian Jessie. Shortly, I noticed that Emacs M-< and M-> wouldn't work. Since then, I have managed to use the Emacs using ESC key instead of the Alt key as the Meta key. After one year of inconvenient use, I finally find what intercepts the Shift - Alt key. It is keyboard layout switching function of MATE. Here is the screenshot of its setting panel: My next question: Are MATE users happy with this default setting?

About two months ago, I installed Debian Jessie (8.1) to the another second-handed laptop PC.  During the install process, I made a non-root normal user account as the installer guided me. One day,  I wanted to add another normal user. Because the Debian system recommendation is to use adduser command, I reviewed its usage and functions. Then I found that the groups to which the initial account belonged were different from the adduser command default groups. I feel peculiar at first, and added the following line to /etc/adduser.conf EXTRA_GROUPS="dialout cdrom floppy audio dip video plugdev netdev lpadmin scanner bluetooth" Then the following command works as expected: adduser --add_extra_groups [new uid] I guess if the tasksel changes the extra-groups default parameters depending on the the purpose of the installation, it is more convenient to the users, at least, to me.

I recently upgraded my wheezy box to jessie. As always, upgrade ended in success. It's amazing for me that all the major upgrade have never made my Linux box ruined. I believe that both well-designed package management system and the Debian developer's effort have achieved this result. Thanks a lot, all the contributors!
