[LightDM] No Keyboard Touchpad with lightdm Mate / Dell Latitude E6420
Hello, I installed last week a Dell laptop E6420 in centos 7 with Mate desktop. Installation looked good, I used a remote connexion through ssh and xrdp session to configure the laptop ( I installed first "X Window system" then "MATE Desktop" and switch to graphical.target) When I finished it, I wanted to login locally on the laptop ; but I faced a strange issue : I cannot use the inputs keyboard and touchpad... I tried to plug a external usb keyboard and mouse : same issue, cannot input. I noticed that the problem seems to be with lightdm service. Because when I stop the service # systemctl stop lightdm and I can logon through tty with using the laptop keyboard. With the lightdm logon screen, the keyboard and touchpad are not working... I am not used to configure keyboard/mouse on linux. Usually It was working good on all my centos 7 or fedora xx installations with Mate Desktop. First time I get this issue. Physically, everything seems to be good : # cat /proc/bus/input/devices I: Bus=0019 Vendor=0000 Product=0005 Version=0000 N: Name="Lid Switch" P: Phys=PNP0C0D/button/input0 S: Sysfs=/devices/LNXSYSTM:00/device:00/PNP0C0D:00/input/input0 U: UniqH: Handlers=event0 B: PROP=0 B: EV=21 B: SW=1 I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button" P: Phys=PNP0C0C/button/input0 S: Sysfs=/devices/LNXSYSTM:00/device:00/PNP0C0C:00/input/input1 U: UniqH: Handlers=kbd event1 B: PROP=0 B: EV=3 B: KEY=10000000000000 0 I: Bus=0019 Vendor=0000 Product=0003 Version=0000 N: Name="Sleep Button" P: Phys=PNP0C0E/button/input0 S: Sysfs=/devices/LNXSYSTM:00/device:00/PNP0C0E:00/input/input2 U: UniqH: Handlers=kbd event2 B: PROP=0 B: EV=3 B: KEY=4000 0 0 I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button" P: Phys=LNXPWRBN/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXPWRBN:00/input/input3 U: UniqH: Handlers=kbd event3 B: PROP=0 B: EV=3 B: KEY=10000000000000 0 I: Bus=0011 Vendor=0001 Product=0001 Version=ab41 N: Name="AT Translated Set 2 keyboard" P: Phys=isa0060/serio0/input0 S: Sysfs=/devices/platform/i8042/serio0/input/input4 U: UniqH: Handlers=sysrq kbd event4 B: PROP=0 B: EV=120013 B: KEY=1100f02902000 8380307cf910f001 feffffdfffefffff fffffffffffffffe B: MSC=10 B: LED=7 I: Bus=0019 Vendor=0000 Product=0006 Version=0000 N: Name="Video Bus" P: Phys=LNXVIDEO/video/input0 S: Sysfs=/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:13/LNXVIDEO:00/input/input5 U: UniqH: Handlers=kbd event5 B: PROP=0 B: EV=3 B: KEY=3e000b00000000 0 0 0 I: Bus=0003 Vendor=045e Product=00cb Version=0111 N: Name="Microsoft Microsoft Basic Optical Mouse v2.0 " P: Phys=usb-0000:00:1d.0-1.2/input0 S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/input/input6 U: UniqH: Handlers=mouse0 event6 B: PROP=0 B: EV=17 B: KEY=70000 0 0 0 0 B: REL=103 B: MSC=10 I: Bus=0011 Vendor=0002 Product=0008 Version=0000 N: Name="DualPoint Stick" P: Phys=isa0060/serio1/input1 S: Sysfs=/devices/platform/i8042/serio1/input/input7 U: UniqH: Handlers=mouse1 event7 B: PROP=21 B: EV=7 B: KEY=70000 0 0 0 0 B: REL=3 I: Bus=0011 Vendor=0002 Product=0008 Version=0300 N: Name="AlpsPS/2 ALPS DualPoint TouchPad" P: Phys=isa0060/serio1/input0 S: Sysfs=/devices/platform/i8042/serio1/input/input8 U: UniqH: Handlers=mouse2 event8 B: PROP=9 B: EV=b B: KEY=e420 70000 0 0 0 0 B: ABS=260800001000003 I: Bus=0010 Vendor=001f Product=0001 Version=0100 N: Name="PC Speaker" P: Phys=isa0061/input0 S: Sysfs=/devices/platform/pcspkr/input/input9 U: UniqH: Handlers=kbd event9 B: PROP=0 B: EV=40001 B: SND=6 I: Bus=0019 Vendor=0000 Product=0000 Version=0000 N: Name="Dell WMI hotkeys" P: Phys=wmi/input0 S: Sysfs=/devices/virtual/input/input10 U: UniqH: Handlers=kbd event10 B: PROP=0 B: EV=13 B: KEY=1000b00000400 0 e000000000000 0 B: MSC=10 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HDA Intel PCH Dock Mic" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:1b.0/sound/card0/input11 U: UniqH: Handlers=event11 B: PROP=0 B: EV=21 B: SW=10 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HDA Intel PCH Mic" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:1b.0/sound/card0/input12 U: UniqH: Handlers=event12 B: PROP=0 B: EV=21 B: SW=10 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HDA Intel PCH Dock Line Out" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:1b.0/sound/card0/input13 U: UniqH: Handlers=event13 B: PROP=0 B: EV=21 B: SW=40 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HDA Intel PCH Headphone" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:1b.0/sound/card0/input14 U: UniqH: Handlers=event14 B: PROP=0 B: EV=21 B: SW=4 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HDA NVidia HDMI/DP,pcm=3" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input15 U: UniqH: Handlers=event15 B: PROP=0 B: EV=21 B: SW=140 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HDA NVidia HDMI/DP,pcm=7" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input16 U: UniqH: Handlers=event16 B: PROP=0 B: EV=21 B: SW=140 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HDA NVidia HDMI/DP,pcm=8" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input17 U: UniqH: Handlers=event17 B: PROP=0 B: EV=21 B: SW=140 Thank for your help. -- Edouard Guigné LMS - Ecole Polytechnique PALAISEAU 01.69.33.57.77

[LightDM] No Keyboard Touchpad with lightdm Mate / Dell Latitude E6420
Hi Edouard, LightDM itself doesn't actually control the keyboard, you should look in the greeter you are using (lightdm-gtk-greeter) or the session (MATE) to see why it's not logging in. You may also want to check that the keyboard is being assigned correctly by running "loginctl seat-status" after starting LightDM. --Robert On Mon, 22 Feb 2016 at 22:12 Edouard Guigné <guigne at lms.polytechnique.fr> wrote:> Hello, > > I installed last week a Dell laptop E6420 in centos 7 with Mate desktop. > Installation looked good, I used a remote connexion through ssh and xrdp > session to configure the laptop ( I installed first "X Window system" > then "MATE Desktop" and switch to graphical.target) > When I finished it, I wanted to login locally on the laptop ; but I > faced a strange issue : I cannot use the inputs keyboard and touchpad... > I tried to plug a external usb keyboard and mouse : same issue, cannot > input. > > I noticed that the problem seems to be with lightdm service. > Because when I stop the service # systemctl stop lightdm and I can logon > through tty with using the laptop keyboard. > > With the lightdm logon screen, the keyboard and touchpad are not working... > > I am not used to configure keyboard/mouse on linux.
