[Kubuntu 8.10] Cant login to X anymore


Hi

Im having Kubuntu 8.10 64-bit on a PC.
Now all of a sudden I cant seem to login.
After entering the username & password, it shows the loading KDE 4.1 splash page - after it shows the first icon, it sort of restarts X and goes back to the login screen back again !

I did try updating to KDE 4.2 yesterday but that doesnt seem to have happened fully I guess.

I can login using console but what am I supposed to edit to get back login using GUI ?
Tried startx - a blank screen shows up with te mouse cursor and then back to console.
Code:
anjanesh@be3:~$ startx

This may have something to do with libplasma.so.3 ?

Did this problem develop after an attempted update to KDE 4.2? I use Ubuntu, not Kubuntu, so I don't follow the KDE updates.

If this problem did develop after an upgrade of KDE, try booting to recovery mode, choose the option "drop to a root shell prompt" and try reinstalling the KDE desktop like this:
Code:
sudo apt-get install --reinstall kubuntu-desktop
Then reboot and try to start X.
If you are unable to reinstall the KDE desktop, then boot to recovery mode again and choose the option "dpkg Repair broken packages" and fix anything that is broken.
If that doesn't work then boot to recovery mode again and choose the option "xfix Try to fix X server" from the menu. Then reboot and try to start X.
If that doesn't work then post your /etc/X11/xorg.conf file.

Yes - this happened after trying to upgrade to KDE 4.2 which didnt happen fully. Its probably the libplasma.so.3 missing file.
"try booting to recovery mode" - how do I do that ?

I can login via console on starting the PC.
sudo apt-get install --reinstall kubuntu-desktop doesnt work
Says you have unmet dependencies
kate : Depends : libplasma3 but it is not going to be installed
kdebase-plasma : Depends : libplasma3 but it is not going to be installed
and a couple of other stuff like
ldeplasma-addons, ksysguard, plasmoid-quickacces

When you boot the computer there should be options in the grub menu to boot Kubuntu, or boot to Kubuntu recovery mode. Hit hit the Esc key on bootup if you do not see the grub menu on bootup and then you will see the grub menu.

sudo apt-get install -f

Excellent!! Glad we got KDE 4.2 working for you.

So how do you like the new KDE 4.2 on Kubuntu? Does it work well? Any problems that you have found? Would you recommend it?

I am running KDE 4.x on Mandriva 2009. It took some getting used to with those "widgets" and the new KDE menu. All things considered, I think Mandriva did a decent job with the new KDE. I have never used KDE or XFCE in Ubuntu. I have always used gnome in Ubuntu. Perhaps I should try the kde-desktop on Ubuntu one of these days.

Hi friends!

i am pretty new to linux an i've got a similar but far worse problem. i have kubuntu 8.10 installed on my hp 2510p. i have always done the updates.
today, something went wrong. first, after aptget downloaded the packages, and before it startet do install them, i was asked to enter a new passwort (which i skipped by not entering anything). second, it reinstalled something like kde-plasma by removing the older packages and installing newer ones. some error occured and i was asked to repair something manually. then the screen turned black and i pressed ctrl+alt+del to restart my machine.

now i m stuck in the same situation as anjanesh. the login screen (which i have had disabled) is coming again and again. i can start the console, but whenever i want to enter something i am asked to enter the passwort which is not accepted then !!! i have no idea why!

when i try to start kubuntu in the recovery mode as suggested i am not able to enter the grub menu because it does not respond to esc. apparently this is another bug (https://launchpad.net/ubuntu/+source/grub/+bug/63969)

i would appreciate any helpful comments and hints!!! thanks a lot!!

Grub must be working properly if you can boot your computer. Do you not see a menu like this:
http://users.bigpond.net.au/hermanzone/p15.htm#gui
when you boot Kubuntu? Your grub menu should look similar, but not identical, to the picture at the top of that page.

If you can at least get a terminal (i.e., console) prompt when you boot, try running these commands:
Code:
sudo dpkg --configure -a
sudo apt-get install -f
Then reboot and see if you can startx. To reboot from the console, just run:
Quote:
sudo reboot
and see if X will start.

If that is not successful, boot to the terminal again and run:
Code:
sudo apt-get install --reinstall kubuntu-desktop
