觸摸板無法在 Debian 9 上執行
我剛剛在聯想 S130-14IGM 上安裝了 Debian 9,但觸摸板根本無法使用。
使用 Ubuntu 沒有問題。
以下是兩個作業系統的結果:
Ubuntu
# egrep -i 'syna|alps|etps|elan' /proc/bus/input/devices N: Name="SYNA3388:00 06CB:8459 Touchpad" P: Phys=i2c-SYNA3388:00 S: Sysfs=/devices/pci0000:00/0000:00:17.0/i2c_designware.0/i2c-4/i2c-SYNA3388:00/0018:06CB:8459.0001/input/input17 # apt list xserver-xorg-input-synaptics Listing... xserver-xorg-input-synaptics/bionic 1.9.0-1ubuntu1 amd64 # dpkg -l | grep -i syna ii xserver-xorg-input-synaptics-hwe-18.04 1.9.1-1ubuntu1~18.04.1 amd64 Synaptics TouchPad driver for X.Org server # xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ SYNA3388:00 06CB:8459 Touchpad id=9 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Video Bus id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ EasyCamera: EasyCamera id=8 [slave keyboard (3)] ↳ Ideapad extra buttons id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

我該怎麼辦?
# egrep -i 'syna|alps|etps|elan' /proc/bus/input/devices N: Name="SYNA3388:00 06CB:8459 Touchpad" P: Phys=i2c-SYNA3388:00 S: Sysfs=/devices/pci0000:00/0000:00:17.0/i2c_designware.0/i2c-4/i2c-SYNA3388:00/0018:06CB:8459.0001/input/input17
您的觸摸板不是通過內部 PS/2 或 USB 接線連接到系統,而是使用 I2C 匯流排。這是一個相當新的發展,Debian 9 的標準核心可能太舊而無法很好地支持這樣的觸摸板。您可以嘗試使用反向移植核心。
有關啟用 Debian Backports 儲存庫的說明,請參見此處
/etc/apt/sources.list
- 基本上,將此行添加到文件中:deb http://deb.debian.org/debian stretch-backports main
然後你應該能夠安裝一個反向移植核心:
apt-get update apt-get -t stretch-backports install linux-image-4.19.0-0.bpo.2-amd64 linux-image-amd64
重新啟動後,您的觸摸板可能會更好。
