using compositing managers in lubuntu 15.10

역시 가벼운 리눅스 데스크탑으로는 LXDE 가 딱 내 취향이다. 적당한 compositing manager로 보기에도 그럴듯 하게 꾸밀만 하고...

몇가지 compositing manager를 lubuntu 15.10 virtualbox guest (vbox 4.3.12 + 5.0.3 guestadditions) 에서 테스트 해 본 결과를 정리해 본다.

install compositing managers

    xcompmgr: sudo apt-get install xcompmgr

    compton: sudo apt-get install compton

    compiz: sudo apt-get install compiz compizconfig-settings-manager compiz-plugins

            or sudo apt-get install compiz compizconfig-settings-manager compiz-plugins-extra compiz-plugins-main compiz-plugins 

location of config files (autostart, desktop.conf)

    /etc/xdg/lxsession/Lubuntu/

    or

    ~/.config/lxsession/Lubuntu/

to use xcompmgr

    in autostart, put the following

    xcompmgr -cCfF -r9 -o.75 -t-9 -l-10 -D5 &

    * xcompmgr doesn't show shadow around the terminal emulator windows & panel, while compton does well

to use compton

    in autostart, put the following

    @compton -c -r7 -o1 -l-9 -t-9 -G -b

    ** compton makes shadow very well, but not make transparent lxterminal, why??? - solved by editing compton.conf

    put the following in .config/compton.conf

        # Opacity

        menu-opacity = 0.8;

        inactive-opacity = 0.8;

        frame-opacity = 0.7;

        inactive-opacity-override = false;

        # WORKS

        opacity-rule = [ "85:name *= 'Chrome'"];

to use compiz

    in desktop.conf 

        windows_manager/command=openbox ; change openbox -> compiz

    in autostart,

        @compiz --replace

    run ccsm (to show window border)

        desktop decoration enable

    cannot move windows, why ???
