Description jsabater 2002-07-19 12:03:13 UTC
(*** This bug was imported into bugs.kde.org ***)

Package:           kdm
Version:           KDE 3.0.2 
Severity:          normal
Installed from:    Debian testing/unstable Packages
Compiler:          2.95 I guess
OS:                Linux
OS/Compiler notes: Cheeney's packages which are not yet in Debian unstable

When starting my computer kdm loads successfully but I cannot input any data from my keyboard. The server seems not to be receiving keypresses but if I choose "Console login" then everything seems ok.

The same problem happens with xdm which in fact happened to me when installing XFree86 4.1. I could override it by deleting my Option XkbRules "xfree86" line in /etc/XF86Config-4. A few days after I tried to add that Option again and it worked!

So I believe the X server is not receiving input from keyboard at kdm login but it's very strange since it does if I go to console log in and then start it using startx script.

I have tried with two keyboards an Acer 6312-TA (ext 4S) and an old one (using an adapter to PS/2): both are behaving the same way.

My motherboard is a Gigabyte 7VRX using VIA KT333 chipset. I am using X-Free86 4.1 with kernel 2.4.19-rc1 with XFS and preemptive patches. I have got a Nvidia GeForce2 Ti 200 and I am using Nvidia drivers which seem to work fine ("nvidia" driver in /etc/X11/XF86Config-4).

Thanks in advance.

there could be multiple reasons:
- the xserver is started while the gettys are not up yet. that causes a
  race for the vt which leaves you with a wedged keyboard. the solution
  is to make sure the display manager is started late enough or adding
  "vt7" at the end of the server line in Xservers.
- the nvidia driver is plainly broken.
- another (possibly debian-specific) x(-server) problem occured. in this
  case you should report this to debian (chris says "do it") and/or
  xfree.

in any case this is not a kdm problem by itself; it's only triggered by
kdm and i can't do much about it.

I am having the problem described here on SuSE 9.1 and KDE 3.2.1. It began only after recent online updates. My video is Tseng. How do I do what is described in comment 1 "start late enough"? Which Xservers is the correct file to examine? My system has 4 of these. /etc/X11/xdm/Xservers does refer to vt7, but I can find no "server line".
