[gentoo-user] mdev: Has anybody managed to get the keyboard and mouse to work under X?

[gentoo-user] mdev: Has anybody managed to get the keyboard and mouse to work under X?

[Alan Mackenzie]

Hi, Gentoo.

As I've said a few times in the current threads, the only thing
preventing me from moving fully onto mdev is not having a working
keyboard and mouse (evdev??) under X.

Has anybody else tried this, and if so, what results have you had?

I have not tried it since they removed the HAL dependency, but I believe you
just need to compile xorg with USE=-udev and put the correct device
information into the xorg.conf file. 

What X uses udev for is to enumeration your devices when it starts, and
associate those devices automatically with the right drivers. From what
Pandu has said, X cannot be made to poll mdev for the information it needs
because the conversion is "backwards" from mdev's perspective: instead of
mdev sending new-device events out to listening userspace applications, X is
expecting to initiate a query into the device manager, which mdev cannot do.

However, if you configure that all manually then X has no more need of a
device manager, udev or otherwise.

Alan, could you post your "init" script here?

I just happened upon this:

http://blackfin.uclinux.org/gf/project/uclinux-dist/scmsvn/?action=browse&path=%2F%2Acheckout%2A%2Ftrunk%2Fuser%2Fbusybox%2Fbusybox-1.18.4%2Fdocs%2Fmdev.txt

and I think the script might need an "mdev -s" line.

Still a conjecture, no guarantees it will work, but if such line does not
exist in your "init" script, won't hurt to try...

Rgds,

  I begin my USE variable with "-*" and add only the necessary stuff.
If you want to run X without udev, then compile xorg-server with
"USE=-udev".  I don't have evdev installed at all.  I've run X without
an xorg.conf.  The only reason I have an xorg.conf now is to allow
xrandr to force a weird 1536x864 video mode on my 1920x1080 monitor when
watching one specific website.

Of course, needless to say (but I'll say it anyway), when you re-emerge X,
you should re-emerge X drivers.
