Hello.
Reconfiguring the keyboard and mouse to evdev.
Code:
egrep evdev /etc/make.conf
INPUT_DEVICES="evdev"

Code:
cat /etc/X11/xorg.conf.d/10-keyboard.conf
Section "InputClass"
    Identifier     "Keyboard0"
    Driver         "evdev"
    Option         "AutoRepeat" "500 30"
    Option         "XkbRules" "xorg"
    Option         "XkbModel" "pc104"
    Option         "XkbLayout" "us,ru(winkeys)"
    Option         "XkbVariant" "nodeadkeys"
    Option         "XkbOptions" "grp:ctrl_shift_toggle,grp_led:caps,ctrl:nocaps"
EndSection


Added support in the core.

Code:
Device Drivers  --->
    Input device support  --->
        <*>   Event interface
        [*]   Mice  --->
              <*>   PS/2 mouse
        -*-   Keyboards  --->
              <*>   AT keyboard


Code:
Device Drivers  --->
    HID support  --->
        <*> HID bus support
        <*> Generic HID driver
            USB HID support  --->
                <*> USB HID transport layer


Code:
Device Drivers  --->
    [*] USB support  --->
        [*]   Improved Transaction Translator scheduling

Code:
emerge xorg-server xorg-drivers -pv

These are the packages that would be merged, in order:

I reboot the computer, there is no support for evdev.
Eempty.
grep evdev /var/log/Xorg.0.log
What to do, what else to rebuild?

Here's my evdev conf
Code:
/etc/X11/xorg.conf.d/97-evdev.conf
Section "InputClass"
   Identifier "mouse-all"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "AutoServerLayout" "on"
EndSection

Section "InputClass"
        Identifier "keyboard-all"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "XkbLayout" "fr"
        Option "XkbRules"  "xorg"
        Option "XkbModel"  "pc105"
        Option "AutoServerLayout" "on"
EndSection

try, the main difference is the MatchDevicePath entry

Did you see this news article (eselect news list to find it):
Code:
2020-04-03-deprecation-of-legacy-x11-input-drivers
  Title                     Deprecation of legacy X11 input drivers
  Author                    Piotr Karbowski <slashbeast@gentoo.org>
  Posted                    2020-04-03
  Revision                  2

The Gentoo X11 Team is announcing the deprecation and future removal of
the legacy X11 input drivers x11-drivers/xf86-input-mouse and
x11-drivers/xf86-input-keyboard. As of 2020-05-01 those input drivers
will be masked for removal.

These drivers have been deprecated for many years, first by
xf86-input-evdev and then by xf86-input-libinput.
 etc...

I think it show in the wiki the keyword xkb_layout
I can tell you my xorg is running azerty and as such that the keyword XkbLayout is working fine
My conclusion is the wiki is bad saying that, without checking the validity of xkb_layout, all keywords used by xorg have for years been in the form of XkbSomething (like XkbModel, XkbVariant...)
oh i see, it use that keyword inside xorg.log
Code:
[   131.389] (**) Option "xkb_rules" "evdev"
[   131.389] (**) Option "xkb_model" "pc105"
[   131.389] (**) Option "xkb_layout" "fr"

Code:
[     9.002] (II) LoadModule: "kbd"
[     9.002] (II) Loading /usr/lib64/xorg/modules/input/kbd_drv.so
This indicates that you have the keyboard driver built. Since you do not explicitly load evdev, I think that the X server is loading kbd, and finding a match. I'm not sure why your choice does not override that, but it would be worth getting rid of the keyboard driver.

On my system, I have use entries in /etc/portage/package.use/10-system as follows:
Code:
*/* INPUT_DEVICES: libinput joystick
*/* INPUT_DEVICES: -keyboard -mouse


I'd suggest creating an entry (in make.conf, or a file in /etc/portage/package.use) that explicitly excludes keyboard. You can check with
Code:
emerge --info
before doing that to show that keyboard is being built (or not).

You could try explicitly loading evdev and see if that works before rebuilding.

Also, try adding this to your evdev config entry:
Code:
MatchIsKeyboard "on"

Code:
[    10.195] (**) Option "XkbRules" "base"
[    10.195] (**) Option "XkbModel" "pc105"
[    10.195] (**) Option "XkbLayout" "us"

This is from your log. (**) indicates this is the setting from config file.

I saw this, I don’t understand why the config does not want to be applied /etc/X11/xorg.conf.d/10-keyboard.conf
I decided to postpone the configuration for now, leave the kbd driver.
A computer in another city, after I’m in place, I’ll start setting up and bring up this topic.
Thank you all for your help.

Possibly it is overridden by another config file file which is sourced after 10-keyboard.conf. You can increase Xorg verbosity for further troubleshooting.
