Can't login via KDE

[alaren]

So, I just ran the auto-updater to try the 10.04 RC.

Everything appeared to work fine, and I rebooted and got to the login screen with no problem.

However, when I type my password, I see a white window appear briefly, then a black screen, then I get dumped back to the login screen. Removing home/.kde does not solve the problem. Creating new users and logging in with them results in the same symptom.

The only solution I've found is to log in via console, then run "startx." It brings me into KDE and all is well.

I don't even know where to begin fixing this.

kdm has it's own logfile in /var/log/kdm - try having a look what's going on in there

[alaren]

This is what appears in that log file:

It's all Greek to me, any help would be appreciated. d^_^b

$ sudo apt-get install ibus
$ibus-daemon -d

Check your log. Ibus daemon is not running. I think it is bug. I have got problem also with dragon and kaffeine players. I reported that bug.

Best.

I have been getting the same problem. Installing and running ibus doesn't seem to have helped at all. I've tried logging in with a brand new user account in case some of my configuration files were wrong, but no luck. My kdm.log looks much like the one posted above.

At the moment I have more-or-less unusable system, so any help would be appreciated.

Edit: I should mention that I'm using the full release, not the RC as above.

Exact same problem here. Kubuntu is totally unusable for me now.

[Mr. Wishes]

More information:
I can't login with startx either - though there are no errors reported, it just gets killed at the same point.

According to apt-get, there is one package that is held back - kdegraphics-strigi-plugins.

I've tried installing gdm so that I can use my computer, but that's been a failure too, I can't choose a gnome session from the login manager, and choosing the kde session results in a black screen.

So has anyone filed a bug on this? Judging from a few searches, no one has actually found a solution to this problem.

[gasdia73]

Same problem here, I think people who upgraded are all stuck with this problem...

[Zorael]

And all packages look okay otherwise?

$ sudo dpkg --configure -a
$ sudo aptitude update
$ sudo aptitude full-upgrade
The logs to check are /var/log/kdm (as mentioned above) as well as /var/log/Xorg.0.log. That Xorg.0.log file refers to the currently running session, so if you have X at the login screen you'll have to look at the last log instead; Xorg.0.log.old in the same directory.

Hi, all. I have the same problem after upgrading to Kubuntu 10.04
On login (often but not always), I type my password and after some time login windows disappear and reappears again. I often have to restart X to be able to login.

Once I'm logged in, I have the same problem on screen unlocking. I can unlock only by typing passwd and clicking return button more than once.

The only error present in kdm.log is:

I have this same problem as this post and haven't found any solutions, do the others in this post still have this problem or has a fix been found?

[stigman13]

I got by my kde problem. I orginally loaded kubuntu 10.04 with an ATI radeon X1600 pro, had install issues with the video freezing even though my PC sounded like it was still doing something. I removed this video card and re-installed 10.04 with the on board crappy video and everything installed and displayed correctly. I then had a login looping issue which I tried several suggestions from this forum which just ended up with the problem in this post, but didnt see any logs with video errors. Without any other suggestions and seeing posts how video cards can cause this problem, I decided to put a nvidia geforce video card I had laying around and everything started working.

I've found a solution. In my case, mysql-server-5.1 was obliterating kdebase-workspace-bin

Try sudo apt-get install kdebase-workspace-bin and there are chances that it'd work.
Spread it if it works.

The same problem after fresh install of Kubuntu 10.04, can't find solution

[metrofun]

I've tried to install Kubuntu 10.10 and Kubuntu 10.04 the same thing - can't login...it may be hardware specific.I have old integrated intel graphic card.

[metrofun]

I tried to use descret video card and everything is ok.Seems it's a problem with my integrated card
VGA compatible controller: VIA Technologies, Inc. CN700/P4M800 Pro/P4M800 CE/VN800 [S3 UniChrome Pro] (rev 01)

I found a solution on russian forum (http://www.linux.org.ru/forum/general/5060498)
Add to the .kde4/share/config/kwinrc (.kde/share/config/kwinrc)
