◎ PCケースのLEDを接続する際に毎回悩む。 :

◎ 作業メモ。 :

sudo aptitude install xrdp -y
sudo reboot
sudo sed -e 's/^new_cursors=true/new_cursors=false/g' -i /etc/xrdp/xrdp.ini
sudo systemctl enable xrdp
sudo systemctl restart xrdp

echo "xfce4-session" > ~/.xsession

vi ~/.xsessionrc

内容は以下。

export XDG_SESSION_DESKTOP=xubuntu
export XDG_DATA_DIRS=/usr/share/xfce4:/usr/share/xubuntu:/usr/local/share:/usr/share:/var/lib/snapd/desktop:/usr/share
export XDG_CONFIG_DIRS=/etc/xdg/xdg-xubuntu:/etc/xdg:/etc/xdg

sudo systemctl status xrdp

sudo aptitude remove xrdp

◎ xubuntu-desktopはNumlockが有効になる模様。 :

$ cat /usr/share/lightdm/lightdm.conf.d/50-xubuntu-numlock.conf
[Seat:*]
greeter-setup-script=xubuntu-numlockx

◎ 手順。 :

sudo apt install git build-essential
sudo apt install xfce4-dev-tools libxfce4util-dev libxfce4ui-1-dev xfce4-panel-dev

git clone https://github.com/xfce-mirror/xfce4-kbdleds-plugin.git
cd xfce4-kbdleds-plugin
./autogen.sh
./configure --prefix=/usr
make
sudo make install

◎ 使い方。 :

◎ インストール手順。 :

sudo apt install gerbera

sudo cp /etc/gerbera/config.xml /etc/gerbera/config.xml.bak
