Chakra 安裝在 Thinkpad X220之調整事項

這是我最近心血來潮想要試試看Chakra這個完全將KDE整合的Arch Linux分支，以下是我的在Thiknpad X220上的調整方法，感謝夢哥和KDE悍將千杯不醉馬克思。

1.Chakra設定小紅點中鍵滾動

sudo kate /etc/X11/xorg.conf.d/20-thinkpad.conf
複製貼上

Section "InputClass"
    Identifier    "Trackpoint Wheel Emulation"
    MatchProduct    "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|USB Trackpoint pointing device|Composite TouchPad / TrackPoint"
    MatchDevicePath    "/dev/input/event*"
    Option        "EmulateWheel"        "true"
    Option        "EmulateWheelButton"    "2"
    Option        "Emulate3Buttons"    "false"
    Option        "XAxisMapping"        "6 7"
    Option        "YAxisMapping"        "4 5"
EndSection

2.Chakra設定小紅點速度和敏感度

sudo kate /etc/udev/rules.d/10-trackpoint.rules

SUBSYSTEM=="serio", DRIVERS=="psmouse", WAIT_FOR="/sys/devices/platform/i8042/serio1/sensitivity", ATTR{sensitivity}="200", WAIT_FOR="/sys/devices/platform/i8042/serio1/speed", ATTR{speed}="200"

並且把/etc/rc.local 寫入

echo -n 200 > /sys/devices/platform/i8042/serio1/sensitivity
echo -n 200 > /sys/devices/platform/i8042/serio1/speed

3.Chakra設定中文環境建置
sudo pacman -S kde-l10n-zh_TW

4.安裝軟體中心
sudo pacman -S appset-qt

5.Chakra 安裝 Dropbox
ccr -S dropbox

6.在chakra中安裝hime輸入法

7.下核心參數來控制省電

輸入 sudo kate /etc/default/grub，然後將原本的GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" 改成

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force i915.i915_enable_rc6=1 i915.lvds_downclock=1 i915.i915_enable_fbc=1 drm.vblankoffdelay=1"

存檔離開。最後輸入sudo update-grub
