stephan-t ... yes, me ... though I use sys-fs/mdev-bb::foo-overlay and sys-fs/mdev-like-a-boss::foo-overlay and not sys-apps/busybox[mdev]. If you have any questions then you're probably best to start a seperate thread ...

Okay, tell me what a different between those package or busybox with mdev support and what the next step?
Your answer put this here |

I think I pretty much covered everything there is to know in that thread ... except perhaps removing evdev from INPUT_DEVICES= if you're going to remove {e,}udev entirely.

So, remove the evdev from input, unmerge the virtual/udev , libudev, libgudev sys-fs/eudev, udev-init-scipts , xf86-input-evdev and set the mouse , keyboard to INPUT_DEVICES.
After when i modified the virtual/dev-manager, never brake the system because i update whole packages?
What packages masked or put the provided list ?
Why xorg-server say set the udev flag ?

stephan-t ... it looks like we have two concurrent threads on this same subject (see: here) as user tw04l124 asked the same question just before JRG split this off from the eudev thread. Anyhow, NO! hehehe ... you need to work out some things first before you start removing packages, you probably have stuff that is built against libgudev and they will break if you do that. You sort of have some of the procedure, but remember removing udev-init-scripts will leave the services in the runlevel, and you will need to start up mdev in their place.
I can see I'm going to end up repeating myself, so I'm best to point you to the mdev wiki page (particularly the "sanity check" section) and mdev-like-a-boss. You should be able to work out a plan of action from those two pages, plus reading what I'd written in the above linked thread (and perhaps also other threads I've contributed to on this subject).
| stephan-t wrote: | | Why xorg-server say set the udev flag ? |
becuase xorg uses 'eudev' to configure the keyboard/mouse ... its not needed, as you can use the xorg-conf.d from mdev-like-a-boss, but you will need to re-merge it with -udev and with INPUT_DEVICES="keyboard mouse" (and 'synaptics' maybe).

Hello,
Can I hijack this thread too ?
I tried busybox[mdev] and mdev like a boss init script, but I have issues :
- the ethernet driver is not loaded, maybe because of firmware
- I use an initramfs to initiatlize a LUKS+LVM2 system, but the /dev/mapper/ entries are not present in the running system, so I cannot mount the remaining partitions (I could do it in the initramfs, but for now, I let the system mount them later) EDIT: http://www.gossamer-threads.com/lists/gentoo/user/270576
USB keyboard is well hot/cold plugged.

I can speak to the /dev/mapper problem.
Add the following line to /etc/init.d/mdev in the populate_mdev() method
Also, auto loading is not done with mdev. You need to add your modules manually, if I recall correctly.
I stopped using mdev because it wouldn't handle joysticks fluidly.

As the Doctor mentioned, no auto loading of modules, you can use /etc/conf.d/modules ... or via preup() in conf.d/net.

This has to be an issue with genkernel (or whatever initramfs you are using) as with better-initramfs I don't have this problem.
I saw that note on the wiki when first setting up my LUKS+LVM2+mdev ... didn't have any issues, so assumed there was nothing in it. Again, the user reporting this was probably using genkernel (or rather, its an issue with the initramfs rather than mdev).

Hmmm ... I think I got this working at one point, but I don't remember how exactly, and don't have a USB kbd handy to test.

stephan-t ... I haven't no, but as its configured via /etc/X11/xorg-conf.d/ it should simply be a matter of having a suitable 10-keyboard.conf

stephan-t,
xorg.conf still works.
I'm not sure if mdev supports evdev but if not the following works for xorg after the keyboard works in the console.
| Code: | Section "InputDevice"
Identifier "Keyboard1"
Driver "kbd"
Option "AutoRepeat" "500 30"
# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# Option "LeftAlt" "Meta"
# Option "RightAlt" "ModeShift"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc105"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# These are the default XKB settings for Xorg
# Option "XkbRules" "xorg"
# Option "XkbModel" "pc105"
# Option "XkbLayout" "us"
# Option "XkbVariant" ""
# Option "XkbDisable"
Option "xkblayout" "gb"
# comment out the next line if you don't have a dvorak keyboard
Option "xkbvariant" "dvorak"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
# why "pc102"
Option "XkbOptions" "ctrl:swapcaps"
EndSection |
If the keyboard won't work in the console, it will be some or all of your kernel USB modules not loading.

The Xorg driver is still work. Use keyboard.conf and mouse.conf from mdev-like-a-boss and add some modification.
I find the documents in Xorg archive : kbd, mouse
Thanks. |

stephan-t ... hwids is needed by pciutils, <usbutils-008 (though the package dependencies currently don't take that into account), and others ... udev-init-scripts isn't needed by mdev, but unless you've purged {e,}udev then you'll find them pulled in as a dependency.

Okay
because i want rebuild package with @preserved-rebuild i get this message
| Code: | [ebuild R ] sys-fs/lvm2-2.02.109 USE="-udev*"
[ebuild R ] app-misc/geoclue-2.1.10 USE="-modemmanager*"

[ebuild R ] dev-libs/libatasmart-0.19-r1
[ebuild R ] x11-drivers/xf86-video-nouveau-1.0.11
The following USE changes are necessary to proceed:
(see "package.use" in the portage(5) man page for more details)
# required by sys-fs/udev-216
# required by virtual/udev-215[-systemd]
# required by dev-libs/libatasmart-0.19-r1

Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages. |

Long time ago cannot see the bug, but some broken things about reinstall the system. Mdev is possibly not work as well with xorg drivers for me. No keyboard and mouse respond because i cannot remove evdev and udev packages. The steps is backwards.
Could I use the another method for my input devices Such like libinput ? |

stephan-t,
I actually have a static /dev - no auto anything.
No kernel devtmpfs or evdev and I still manage to have root in LVM on top of raid5.
Its just the way it was is 1999 when I started playing with Linux.

stephan-t ... well, I can assure you it does work, and that no {e,}udev is needed ... at least as far as those packages I have installed are concerned, and the useflags enabled, etc.
If you have x11-drivers/xf86-input-evdev then this suggests you have the udev useflag enabled on x11-base/xorg-server. If you get no kdb/mouse without udev then you probably don't have /etc/X11/xorg.conf.d/* configured for a kbd/mouse/trackpad.
It's possible that other packages are pulling in sys-fs/{e,}udev ... specifically virtual/dev-manager ... but without knowing what you're doing, or what you've done, it's difficult to debug the issue.

AFAIK, that is exclusively for wayland ... so no.

Can I find the Wiki?
Okay but this manage all things then I have: like keyboard, trackball or other devices?
@khayyam
I did same steps than some months earlier. But I'dont know what part not work. I have a xorg.conf.d and all settings file from mdev-like-a-boss. Set the right INPUT_DEVICES in make.conf and rebuild packages without udev. |
