[FIXED] Blank, Black Screen After Login

[pablo173]

I'd been happily running Kubuntu Karmic 9.10 for several months, when yesterday I got a popup notice that an upgrade to Lucid had just become available. I eagerly started the update process, not realizing that I was getting Ubuntu 10.04, not Kubuntu 10.04.

Now, although at bootup the login screen appears and works, my desktop does not appear, only a black screen. I see the cursor, but nothing else. I can login from a terminal, but of course, no GUI.

How can I fix this? Trying to reinstall Karmic involves setting up the partition table. I'm not exactly ignorant about this, but I get an error from the install GUI saying I haven't designated a root partition. Unable to figure out how to do this.

My system is a 64-bit Win 7/Kubuntu dual boot, and I don't want to mess up the Win 7 part, cause that's my backup system.

Thanks for any help.

Did you interrupt the update process?

I suggest you first try logging in to the CLI, and running these:

sudo service kdm stop

sudo dpkg --configure -a

sudo apt-get update

sudo apt-get dist-upgrade

sudo service kdm start

If that doesn't run X, then you might want to try

sudo apt-get install kubuntu-desktop

and then reboot the system and see what you have.

None of the suggested commands should interfere with booting Windows -- that would only happen if you choose to install Grub (again).

Although, I can think of other recommendations for a backup OS ....

I had a similar issue, the plasma desktop was not working. I could still use Alt-F2 to get to my apps.
