After I used the /etc/X11/default-display manager to change the default Login Manager from GDM to KDM, it doesn't properly.

I have installed KDM from the Debian CDs. (I have all 14.)
I only use stable software (from the Debian CDs) on this machine.

Now, KDM starts just fine.
But the keyboard doesn't work on KDM!!
This is ridiculous. It is just a simple Logitech Keyboard and I have never had any problems with this one.
Now, using the mouse, when I restart X, then they keyboard works fine.
But KDM doesn't let me in.
After I enter the username and the password, the screen goes on Black for a while and comes back to the login screen again.
Then I have to select console login and then I can only use startx to go to GNOME.


Please help me as this is getting strange.

I had a similar problem and simply use GDM. In my opinion there's no reason to run XDM at all anyway. It doesn't look good, it's not significantly lighter weight nor is it particularly configurable. I'd suggest switching back.

Hi,

Try running as root or via sudo:

dpkg-reconfigure kdm

Sorry I thought you were talking about XDM. I have to say that my advice still stands as I've alsways experienced less trouble with GDM than anything else.

Hmm..good idea.

I will try that.

There is a known bug with the older kdm which I struggled with for ages. Normally you can go back to the command line and then wait for kdm to start again and everything is normal. The cure for me was to apt-get --purge remove kdm and then re-install with apt-get off the net.

Hmm...But will the new version of KDM work with this pretty old KDE of Debian Sarge?

Otherwise, not to worry much. GNOME Login manager is working fine.

if you're running 3.1 which you say you are then yes it does work. I started off with Woody and upgraded to Sarge (then testing) and had this problem about 6 months ago because for some reason the kdm was not upgraded. purging it from the system worked.

Ok. I haven't upgraded from Woody in this case.

It is a clean install. Ok I will try that purging and reinstalling.

Will post back in a few minutes now.

Done that as root.

Try apt-get remove kdm --purge.

That would be: apt-get --purge remove kdm

EDIT: Arrr, beaten to it

Oh yeah. now I remember.

(Done with apt-get remove)


But now I remember after this reinstallation, that the last timei installed KDM, it was downloaded over security.debian.org.

So I don't have a reason to complain. maybe the package wasn't downloaded properly. I will retry and post back.
