When I found that Synology no longer supported LMS I decided to revert to Plan A: use a desktop computer. My chosen computer is an Acer Revo, but my model has a poorly specced Intel Atom. It claims to be X64, but chokes on a 64bit Linux distribution. I installed lubuntu 18.04 (the most recent 32bit distribution I could find). Lubuntu requires very little of the computer resources and still manages a useful performance.
I wanted to have the choice of running it as a full desktop system with a monitor mouse and keyboard or running it 'headless' just to have LMS running. Full desktop mode is important for adding new music files, LMS modules and general system updates. Even the Synology NAS, consumes about 8 Watts at idle. The tiny Revo consumes about 28 Watts at idle. For this reason, I only wanted it running when it was in use, I wanted to be able to push the Power button and go straight into running the LMS. When I had finished, I wanted to push the Power button and have it shut down. Problem No. 1 is that Lubuntu 18.04 requires a password to boot. Problem No. 2 is that it still brings up a login requester even when set to passwordless login. SETTING LUBUNTU 18.04 TO PASSWORDLESS, AUTO-LOGIN. Change /etc/lightdm/lightdm.conf so that it looks like this, > [SeatDefaults] > autologin-user=<your-user-name> > autologin-user-timeout=0 > user-session=Lubuntu > greeter-session=lightdm-gtk-greeter > <blank line> If there is no lightdm.conf file, create one (sudo leafpad - because you need root permissions). If there is no last blank line, your system might freeze. STARTING UP LMS WITHOUT A PASSWORD. This requires a change to the sudo system. You should consider using visudo to do the text editing as this will check the syntax. > visudo -f /etc/sudoers.d/logitech If you are careful, you can still use sudo leafpad. Make sure there is a blank line at the end of the file. File Name: /etc/sudoers.d/logitech > <your-user-name> ALL=(ALL) NOPASSWD: /usr/sbin/service > logitechmediaserver * > <blank line> This file uses the * character to match all of the LMS commands such as start, stop and restart. Leaving the /etc/sudoers file alone and putting the entries in /etc/sudoers.d should mean that updates will not delete the configuration. Try, > sudo service logitechmediaserver start It should run without a password being necessary. You shouldn't need to reboot. RUN LMS AT STARTUP If you do your own research, you may find solutions based on rc.d. During a lubuntu update I saw the line, > update-rc.d: warning: start and stop actions are no longer supported; > falling back to defaults When I tried one of these methods, LMS started passwordless, but with user=Root. Nothing I could find would make it revert to user =. I reinstalled lubuntu and LMS. The official Ubuntu method is very easy (and safe). You could just create a file with leafpad (/home/roy/.config/autostart/logitechmediaserver), but I suggest, > sudo apt install gnome-startup-applications > > gnome-session-properties Click Add and enter the command to be executed at login (name and comment are optional). For example, to make Firefox start automatically, it's sufficient to type 'firefox' in the Command field and confirm with Add. In our case, type 'sh ' (you need the space as the third character) and browse to the startup file. I created the file ~/home/<your user name>/Startup/logitechmediaserver.sh > sudo service logitechmediaserver start > sleep 3s > <blank line> Change the file permissions to make it executable. The line 'sleep 3s' allows time for any text that may be sent to stdio. It works without, but best to be safe. If you reboot, you should be able to type the URL 127.0.0.1:9000 into Firefox or another browser and it should load up the LMS user interface. I also use this method to get the screen resolution higher to make the menus in apps like Libreoffice-writer larger: 'xrandr --dpi 130' in file, xrandr.sh. XFCE POWER MANAGER Lubuntu defaults to 'Ask' when the power button is pressed: it brings up the logout menu. Change 'When Power Button Is Pressed' from 'ask' to 'Shutdown' Reboot. Oh dear, does it still bring up the logout menu? There appears to be a bug in Xfce Power Manager. > ~/.config/xfce4/xfconf/xfce-perchannel-xml /xfce4-power-manager.xml has the correct line, > <property name="power-button-action" type="uint" value="4"/> but it is ineffective. There is a possible work around. If you do not have an /etc/acpi folder, > sudo apt-get install acpid Check /etc/acpi/powerbtn.sh delete all but the last line, > /sbin/shutdown -h now "Power button pressed" > <blank line> If the file does not exist, create it. Reboot If you still get the logout menu, try pushing the Power button for a moment and then pressing 'Enter' on the keyboard. If this closes the system, then this is your only way of doing it in 'headless' mode. Restore powerbin.sh to its previous contents, or delete it altogether if you added it. If you installed acpid, then uninstall it. ------------------------------------------------------------------------ Roy Leith's Profile: http://forums.slimdevices.com/member.php?userid=35534 View this thread: http://forums.slimdevices.com/showthread.php?t=117134 _______________________________________________ Squeezecenter mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/squeezecenter
