No Keyboard/Mouse in X

maruru · n00b Joined: 22 Sep 2015 Posts: 13

I am working on a more or less fresh installation of Gentoo 4.0.5 (and never used Linux on this computer before).
I use a USB keyboard (Razer Deathstalker Ultimate) and a USB mouse (Razer Naga 2012).
Until now I have been using the terminal to play around, but now I want to install KDE 5 Plasma. So I followed the Wiki on how to install X.
At the moment, I have X installed and a xconfig file generated by nvidia programs.
When I `startx`, I can see the basic GUI, but neither my keyboard nor my mouse work.
I can use CTRL+ALT+F1 to go back to the terminal.
How can I fix this problem?

You have INPUT_DEVICES="evdev", this means no keyboard or mouse driver will be built. However, in xorg.conf you want to load these drivers. Try without InputDevice sections first, then add the configuration options you need. If it still doesn't work make sure you have evdev enabled in kernel.

I seem to get away with not using xorg.conf at all nowadays in my desktop box, but then again I stopped fighting systemd on there.

In your case however, I agree with others suggesting to add keyboard and mouse in make.conf INPUT_DEVICES, and possibly also add AutoAddDevices" "false" in xorg.conf ServerLayout section.

Thank you a lot for your quick answers!
- evdev is enabled in the kernel
- I am using eudev, hence I have `udev` in my USE flags (I rebuilt everything after configuring my USE flags)
- How do I disable hotplugging? Why should it be disabled (does eudev manage hotplugging for xorg)? Why is it enabled even though I use eudev (If I understand you corrctly, hotplugging should be disabled for me)?
I will test all other suggestions tonight (I am at work right now)

I removed the InputDevice sections -> still no keyboard/mouse.
INPUT_DEVICES="keyboard mouse" didn't change anything (so I put back evdev
emerge -pv virtual/udev

Code:

[ebuild R ] virtual/udev-215::gentoo USE="-systemd" 0 KiB
emerge -pv xorg-x11

Code:

[ebuild R ] x11-base/xorg-x11-7.4-r2::gentoo 0 KiB

emerge -pv xorg-server

Code:

[ebuild R ] x11-base/xorg-server-1.16.4:0/1.16.1::gentoo USE="glamor ipv6 nptl static-libs suid udev wayland xorg -dmx -doc -kdrive -minimal (-selinux) -systemd -tslib -unwind -xnest -xvfb" 0 KiB

`AutoAddDevices "false"` results in a `(EE) no screens found(EE)` error.
udev is scheduled by openrc and running.

Once again, x11-base/xorg-x11 is a useless metapackage, so that part proves nothing.

Yet, going by useflags on xorg-server, even with eudev things should work.

So, check if input devices are correctly marked by udev, xf86-input-evdev is installed and the content of xorg log once it is.

well.. just found out something very interesting!
I have 2 monitors connected at the moment (the second one being an Apple Cinematic; this one has already caused me some BIOS trouble a few years ago).
When I disconnect the second one, keyboard and mouse work!

btw, cat /dev/input/mice` and then CTRL+C kinda breaks the terminal by replacing all sorts of characters with (random?) ascii chars. Is that normal?

sounds like you are making progress, but I'm not sure if it was clear, after changing INPUT_DEVICES, you should:
