Posted: Sun Dec 25, 2022 11:21 pm Post subject: No keyboard with Xorg IdeaPad L340 [SOLVED]

Some time ago, the keyboard stopped working along with the touchpad and mouse but it was only while using X

On TTY everything always worked.

I was able to solve the mouse and touchpad failure by adding a driver to the kernel. However, no luck with the keyboard yet.
I suspect something changed during some update and I have not been able to find it. It is probably something very minor. Any suggestions?

Would you be able to tell me where in the description of the problem, I may have given the impression that I am using an xorg.conf ?

Also, I can use an external wireless or wired keyboard connected to the laptop as well as a keyboard though vnc.

Somewhere, some driver is not doing what is suppose to do and something changed somewhere in the updates.
For the mouse, I was able to find the driver that somehow, was on the kernel but one day, out of nothing, stopped being.
The mouse works well.

I think it was this part:

HeXiLeD wrote:

# ls /etc/X11/xorg.conf.d/

Code:

20-keyboard.conf 20opengl.conf 40-libinput.conf

Those fragments are not overwritten by Portage, and are parsed as parts of an Xorg configuration file.

So I decied to re-install gentoo since I also wanted to do some new hard drive partitioning.

Surprise to find out that these issues remain on a fresh install.

I have nothing inside /etc/X11/xorg.conf.d/

# ls /usr/share/X11/xorg.conf.d/

Code:

10-quirks.conf 40-libinput.conf nvidia-drm-outputclass.conf

On tty, the keyboard works.
Drivers are loaded/active. This is with Xorg only

6.1.46-gentoo-x86_64 #1 SMP PREEMPT_DYNAMIC

Edit:

I just found out that it is trying to use evdev

$ setxkbmap -print -verbose 10

Code:

Setting verbose level to 10
locale is C
Trying to load rules file ./rules/evdev...
Trying to load rules file /usr/share/X11/xkb/rules/evdev...
Success.
Applied rules from evdev:
rules: evdev
model: pc105
layout: us
Trying to build keymap using the following components:
keycodes: evdev+aliases(qwerty)
types: complete
compat: complete
symbols: pc+us+inet(evdev)
geometry: pc(pc105)
xkb_keymap {
xkb_keycodes { include "evdev+aliases(qwerty)" };
xkb_types { include "complete" };
xkb_compat { include "complete" };
xkb_symbols { include "pc+us+inet(evdev)" };
xkb_geometry { include "pc(pc105)" };
};

However the whole system is compiled with -evdev and +libinput

The problem is a kernel driver. Somehow while playing with kernel driver and adding some while removing some and vice-versa i was able to get the touch pad to work. I am unsure which driver is because I also loaded a kernel with all the usb, acpi and pci support compiled as modules and only a wireless mouse worked. _________________ Do you hear the sound of inevitability?

So far no progress with this issue. Everything suggests that maybe some driver dependency is not being loaded or perhaps a very specific xorg configuration is needed.

The keyboard, touchpad and mouse, work on tty but once X is started they do not work anymore.

At some point in the kernel recompilations, the touch pad worked but right after was gone.

Using an external keyboard and mouse, works, both on TTY and X.

I have tried with configs both on the following paths. Not using any configuration to see if Xorg detects the hardware, currently is a fail as it will not even detect the external keyboard and mouse.

Code:

# ls /etc/X11/
chooser.sh Sessions startDM.sh xinit xorg.conf.d
# ls /etc/X11/xorg.conf.d/

Code:

# ls /usr/share/X11/xorg.conf.d/
10-evdev.conf 10-quirks.conf 20-keyboard.conf 40-libinput.conf 70-synaptics.conf nvidia-drm-outputclass.conf

cat /usr/share/X11/xorg.conf.d/20-keyboard.conf

Code:

The gentoo live CD with graphical interface, does work. Somehow the live cd detects and gets the laptop keyboard, touchpad and mouse to work but I have no idea how or what is the difference.

On every kernel changes this is executed:

Code:

mount /boot
genkernel --luks --no-lvm --no-zfs all
grub-mkconfig -o /boot/grub/grub.cfg
emerge $(qlist -CI x11-drivers)

A few more details about this issue:

Since the gentoo GUI Live CD works without this keyboard problem, I decided to copy that kernel config and use it to recompile the kernel.
After that I was able to get the touchpad to work. However the touch pad also sometimes worked with the default install and genkernel.

Oddly enough, if I do an manually changes on the kernel and recompile, I lose the touchpad functionality.
This is seems to be something that affects genkernel from picking up whatever driver is needed. (assuming that this problem is a kernel driver issue)

NOTE: external usb keyboards and mice always work with X as well the tuochpad and laptop keyboard on TTY

I installed:

Code:

[I] app-misc/evtest
Available versions: 1.33 1.34 1.35
Installed versions: 1.35(12:10:49 AM 12/24/2023)

The Keyboard info:

So the keyboard does work, but just partially?!

Quote:

PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp

PS/2 AUX Port: This usually refers to the PS/2 port used for connecting a mouse.
• Disabled: The system's PNP mechanism did not detect an active device on this port.
• i8042.nopnp: This is a kernel boot parameter that you can use to override the automatic detection and force the system to recognize the PS/2 port.

Code:

GRUB_CMDLINE_LINUX="…...i8042.nopnp"

Did not resolve the issue. I lost the touchpad. External keyboad and mouse, still worked.

There are several other i8042 parameters that can be used to troubleshoot or configure keyboard and mouse issues, such as i8042.nomux, i8042.reset, etc. Use these if you encounter specific issues related to PS/2 devices.

Adding i8042.nomux or i8042.reset got the touchpad back to functionality on X but not the native laptop keyboard

Quote:

PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp

Enabling the PS/2 AUX port (typically used for a PS/2 mouse) on a Linux kernel usually involves ensuring the correct kernel module is loaded and potentially adjusting kernel boot parameters if automatic detection isn't working.

Next I tried to compile the issue (possibly) related drivers as modules:

<M> Mouse interface
<M> PS/2 mouse
<M> AT keyboard
<M> PCI PS/2 keyboard and PS/2 mouse controller
{M} PS/2 driver library
{M} i8042 PC Keyboard controller

and added

Code:

[*] eGalax TouchKit PS/2 protocol extension

Compiling everything as modules, the touchpad functionality is lost on X
External usb kbd and mouse works. Native laptop kbd and mouse also work on TTY.

Evtest still reports the same as before.

Psmouse & i8042 driver were module as not automatically loaded

According to this link. They claim a firmware bug. However, the laptop native keyboard and touchpad, worked for a long time before this issue and still works with the gentoo graphical live cd. https://bbs.archlinux.org/viewtopic.php?id=277260

After updating the Bios and try the kernel, neither native kbd or touchpad worked.

Decided to do a new genkernel kernel from make defconfig
Both native kbd and touchpad/mouse are not recognized or work

I am out of ideas.

I am gravitating towards this problem being a udev problem.

Why is the video bus being tagged as keyboard?

Keyboard:

udevadm info /dev/input/event2

Code:

P: /devices/platform/i8042/serio0/input/input2/event2
M: event2
R: 2
U: input
D: c 13:66
N: input/event2
L: 0
E: DEVPATH=/devices/platform/i8042/serio0/input/input2/event2
E: DEVNAME=/dev/input/event2
E: MAJOR=13
E: MINOR=66
E: SUBSYSTEM=input

Touchpad:

devadm info /dev/input/event19

Code:

P: /devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-2/i2c-ELAN0626:00/input/input20/event19
M: event19
R: 19
U: input
D: c 13:83
N: input/event19
L: 0
E: DEVPATH=/devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-2/i2c-ELAN0626:00/input/input20/event19
E: DEVNAME=/dev/input/event19
E: MAJOR=13
E: MINOR=83
E: SUBSYSTEM=input

If I do:

evtest -–grab /dev/input/event2
I get feedback from the native keyboard. All keys work

evtest –-grab /dev/input/event19
I get feedback from the native touchpad.

Why is the keyboard being tagged as the video bus?

If udev is incorrectly identifying a camera device as a keyboard, it could be due to a misconfiguration in the udev rules or an issue with the device itself.

udevadm info -a -n /dev/video0

Code:

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

udevadm info -a -n /dev/input/event2

Code:

dmesg | grep -i udev
and no output

udevadm control –reload

Code:

Failed to send reload request: No such file or directory

What am I missing here? I am not running systemd. I am with openrc.

Code:

ls: cannot access '/run/udev/control': No such file or directory

If the socket file is missing, it could indicate a problem with the udev installation or system configuration. So I reinstalled all the packages named udev.

Code:

emerge virtual/libudev virtual/udev sys-fs/udev-init-scripts sys-block/io-scheduler-udev-rules sys-apps/udevil dev-libs/libgudev

Recreating the Missing Control Socket

Code:

mkdir -p /run/udev
mknod -m 0666 /run/udev/control c 10 62

udevadm control --reload

Code:

Failed to send reload request: Connection refused

rc-service udev start
and
udevadm control –reload worked

Created an udev rule for the camera:
nano /etc/udev/rules.d/99-custom-camera.rules

Code:

SUBSYSTEM=="usb", ATTRS{idVendor}=="04f2", ATTRS{idProduct}=="b604", TAG+="uaccess", TAG+="udev-acl", SYMLINK+="video%n"

udevadm control –reload
rc-service udev restart

However, the videobus is still being tagged as keyboard
https://bbs.archlinux.org/viewtopic.php?id=231640

The camera does work
The native keyboard and touchpad do not.

lsusb -t

Code:

Create a udev rule to blacklist this conflict:

Code:

echo ‘ SUBSYSTEM=="usb", DRIVER=="libinput", ATTRS{idVendor}=="04f2", ATTRS{idProduct}=="b604", ATTR{authorized}="0"’ >> /etc/udev/rules.d/90-blacklist-webcam-keyboard.rules

udevadm control –reload
rc-service udev restart
reboot

Camera works. Keyboard does not.

Conclusions so far:

I am not sure if my custom udev rules are proper and the only thing I can think of is to create a udev rule for the keyboard but without ATTRS{idVendor}, ATTRS{idProduct} I am not sure how to do it.

Can anyone help with this?

nano /etc/udev/rules.d/20-keyboard.rules

Code:

SUBSYSTEM="input", KERNEL=="event2", ATTRS{name}=="AT Translated Set 2 keyboard", ACTION=="add", ENV{XKBMODEL}="pc105", ENV{XKBLAYOUT}="us_intl", ENV{XKBVARIANT}="altgr-intl,abnt2,qwerty,euro"

Code:

SUBSYSTEM=="input", KERNEL=="event2", ATTRS{name}=="AT Translated Set 2 keyboard", ACTION=="add"

The root cause of this problem was a change somewhere some time ago with some updated. Someone removed important configurations from some package that got updated
The Gentoo live dvd (with the GUI) does work and recognizes the native keyboard and touchpad.
This is a fresh clean gentoo install
