Upgraded xorg-server and the Mouse and Keyboard Stopped Working?

[Amit Yaron]

I upgraded xorg-server to version 1.20.8_2,1 today not from an active X 
session. and the keyboard and mouse stopped working.
(Dealing with the monitor was easier: just upgrade xf86-video-vesa or 
xf86-video-scfb).
Even after upgrading xf86-input-mouse and xf86-input-keyboard, they 
didn't work.
So, I checked the log file '/var/log/Xorg.0.log', and found there the 
following text:

[  4546.466] (EE) config/devd: error 1 adding device /dev/uhid0
[  4546.466] (II) config/devd: EVDEV_SUPPORT is enabled, ignoring device 
ukbd0
[  4546.466] (II) config/devd: EVDEV_SUPPORT is enabled, ignoring device 
ums0

Ducked the message about "ums0" from my Lynx browser, and found that 
there is an "evdev" (event device) driver, and it was not installed on 
my machine. Searched it with 'pkg search evdev", and found that the 
relevant package/port name is 'xf86-input-evdev' (path to port: 
'/usr/ports/x11-drivers/xf86-input-evdev').
Installed it. Now, the keyboard and mouse work.
  I think that installing the driver should be a part of 
installing/upgrading 'xorg', or at least a line about the driver should 
be added to the handbook.
