Bug Description

Binary package hint: kdebase-workspace

I upgrade one-user Kubuntu from Lucid to Maverick. After that I try to add second user. KDM always ask for password when this new user try to login to the system first time. But this time KDM ask password, but not allow to enter them - text fields of new password windows does not react to keyboard and mouse. Buttons Ok and Cancel still works.

On a 2 bit install, I can't replicate this exact problem, but something close. I was able to set the password, but the actual login failed and then I couldn't seem to get focus to type in the user ID or password. After restarting X I could log on.

As anyone having this problem on 32bit or is everyone 64bit?

Nevermind. I've replicated it.

BTW, it looks like if you don't set a password at all, then you can at least enter the password. I gather those of you who've had this problem set an initial password in userconfig and then the user has to change it on first login?

Additionally, if I restart the system then it works fine.

Does this match what others see?

Proposed release note:

After a new user is created in Kubuntu systemsettings, they will be prompted to change their password when they log in for the first time. There is an issue in 10.10 that prevents the new password from being entered. In order to avoid this problem, the X server needs to be restarted before the new user logs in. After logout, click on the red logout button on the KDM screen and then click on "Restart X Server". Once the KDM login screen returns, the new user should be able to log in normally.

This bug still occurs in KDE 4.5.4 (Kubuntu PPA, so maybe it was fixed in the official repos with KDE 4.5.1 meanwhile ?)

It was reported upstream here but there are only Kubuntu users so it might not be relevant : https://bugs.kde.org/show_bug.cgi?id=260758

It's not fixed, but the work around in the release notes will make it possible.

OK, I've propagated this from the 10.10 release notes. Please edit on the wiki if it's no longer accurate.

I found another workaround to this.

When the password prompt comes up, press OKAY (leaving it blank), it will then give an error that the password is blank and you will now be able to fill in the boxes. At this point the password MUST be different than the original. Occassionally, I have found while typing in the new password a second time, my laptop will lock up, but a hard reboot will allow you to try again and proceed to logging in.

Similar symptoms here on Kubuntu 11.04, 32bit.
(This has only showed up when trying to demonstrate Linux to a Windows user, rather embarrassing.)

The restart X server workaround didn't work for me, but the click ok on empty fields did on one occasion. Sometimes, the change token dialog is completely unresponsive, can't enter text in fields or click buttons. The login dialog is also disabled and greyed out, so it virtually locks up the machine.

This issue is super scary. As is KDM Code. I was running around in it all afternoon but could not find the cause.

It seems jolly obvious that there is a focus issue (or key grab) but it is not exactly clear what causes it :S

I'm experiencing the same bug on KDM 4.6.5. I created a new user and when tried to login with it, I'm asked to change the user's password but I'm unable to type anything at all.

I should mention, that I start a new session through KDE's KMenu after being logged in as another user.

Cheers!

I'm having the same problem with Kubuntu 11.10. This seems like a long running bug that nobody is paying attention to.

Reproduced on Kubuntu 11.10 32 bits and 64 bits
The only way to change the password is to connect in console mode.
This bus is 1 year old

If you change /etc/kde4/kdm/kdmrc by setting these values, you can avoid this bug:

# Whether to grab keyboard and mouse while the greeter is visible. Grabs
# may improve security, but make on-screen keyboards, etc. unusable.
# "Never" - never grab
# "IfNoAuth" - grab if the display requires no X authorization
# "Always" - always grab
# Default is IfNoAuth
GrabInput=Always
# Hold the X-server grabbed the whole time the greeter is visible. This
# may be more secure, but it will disable any background and other
# X-clients started from the Setup script.
# Default is false
GrabServer=true
# How many seconds to wait for grab to succeed.
# Default is 3
GrabTimeout=3
