[SOLVED] Login problem after upgrading to Kubuntu 10.04.1

[sandro54]

Hi Guys,
I have a problem after upgrading from Kubuntu 9.10 to 10.04.1 (LTS): after reboot I get the login panel but when I type login + password, the system begin to go ahead but immediately comes back to login panel, so I can't get the Desktop obviously .

I checked the following :
The kubuntu-desktop is already in place the kdm I think it works well (start & stop work) and the file xorg.conf has been rebuilded with the cmd "dpkg-reconfigure.......xserver-xorg".

please do you have any idea about the problem ?

thanks in advance.

Sandro

Re: Login problem after upgrading to Kubuntu 10.04.1

Hi

Some things to try

Please select recovery mode from the grub menu (if you are not dual booting after the BIOS post hold down escape to show this) and firstly pick the fix broken packages option. Then select resume normal boot. If the same thing happens reboot the machine and go into recovery mode again and pick the command line option. Then type

startx

One of 2 things will happen. If it starts then that suggests a permission issue whereby the administrator (root) can run KDE but you as the user can't. It can be fixed but the command to do so can be dangerous. When I used it by putting a space in the wrong place I wiped my entire home directory Alternatively (and hopefully) you will get the same problem which suggests a problem with the desktop instead. In that case get back to the command line prompt and type

sudo apt-get install plasma-desktop

Come back and let us know what happens.

Check your available drive space: df -h
a full system. home, or temp could prevent log in.

Check your home directory for files owned by root: cd ~ && ls -Rla |grep root

Check to see if an error is being produced after you attempt log in: dmesg

Re: Login problem after upgrading to Kubuntu 10.04.1

Hi,
I tried all your suggestions but the login doesn't work , I always getting again the login panel after typing the password.

The plasma-desktop is already in place.
About permissions I noted the files .Xauthority was root permissions and .ICEauthority was user permissions. so I removed both these files . After reboot I got the same problem, so I checked these files .Xauthority now it was the user permissions but the file .ICEauthority wasn't created . is it normal

I checked also the drive space is OK and I have only the following home dir. with root permissions:

drwxr-xr-x 5 root root 4096 2009-04-30 23:30 ..



please what can I do now ??

thanks

Re: Login problem after upgrading to Kubuntu 10.04.1

/home is always root. Do you have your directory in /home, such as /home/<your name here>? The directory should be identified to you as owner and group.

Re: Login problem after upgrading to Kubuntu 10.04.1

Firstly, can I assume you have done a backup of your data?

From what I have read elsewhere, there is a possible conflict between your new kubuntu installation and your existing kde settings. If you have a live cd one way you can do this is to load the live cd. If you cannot access your home directory you will need to create a new user within the live environment. The user ID number must be 1000.

Then logout (don't shut down) of that session and login as the user you have just created.
Copy any data you don't want to risk onto a different medium if you haven't already backed up. Then rename (don't delete) the following hidden folder:

/home/.kde/share/config (for ease give it a suffix)

Then close down the live session and try booting into the installed one. With a spot of luck you will now be able to login but it will be to a virgin desktop. Whilst your data will still be there you will have to reconfigure your KDE apps.

To the purists: Sorry I've gone down this route but I once was unable to log in and I attemtped to delete a file within the home directory. What happened was I put a space in the wrong place and in an instant wiped out the home directory so I'm very choosy about the commands I now use

Hi,
thanks for all your suggestions,
but I have a live CD with kubuntu 9.10; is it all right or must I use 10.04.

thanks and regards

Re: Login problem after upgrading to Kubuntu 10.04.1

Any should do - all you need it to do is enable you to access your home directory. However if you have adopted an encrypted filesystem or are using ext4 then you might need 10.04.

As you don't have a disk for 10.04 I imagine you upgraded over the net, in which case you should be okay.

Re: Login problem after upgrading to Kubuntu 10.04.1

Hi,
in the end I made a Kubuntu 10.04 live CD and I made the login from the live CD, then I renamed the dir "config" as follows :

cd /home/val
sudo -i (for enabling access to dir ".kde")
cd .kde
cd share
sudo mv config config_old

After I checked the rename has worked.
Then I closed down the live session and I tried booting from the installed 10.04 but the result is still the login loop. I don't go on kubuntu desktop but after inserting password I get again the login panel, as before.

I tried the recovery mode booting using "failsafex" and "dpkg" and "netroot" but nothing works: so I have no network connection.

In any case I have a backup copy of /home

please I really need support.

thanks very much.

Re: Login problem after upgrading to Kubuntu 10.04.1

Boot into your recovery kernel from the Grub menu. This will put you at a command line prompt operating 'as root.

At the prompt type:

chown -r username:username /home/username

where username is your username you log in with. This will recursively change the ownership to your user on all files and directories in your /home directory. I'm believing that some of your files in your /home directory have been changed to being owned by root - not a good thing.

After doing this, then type:

shutdown -r now

and try logging in again. My guess is that you will be successful.

Re: Login problem after upgrading to Kubuntu 10.04.1e a

Hi everybody,

I finally reinstalled kdm, kubuntu-desktop, kubuntu-plasma from the connection but the login problem is still in place. I didn't reinstall "KDE" because I don't know the name of the package.

do you know it ??

I tried the login "Failsafe" from the login menu panel and also this doesn't work, so I begin to suspect that problem could be related to video driver. below are my settings:

Screen: 15.4 WXGA (1280x800)
Card NVIDIA: GeForce 8400M GT GPU
NVIDIA Driver version: 195.36.24
GPU (Graphics processor): GeForce Go 7300u

I noted inside "Xorg.0.log" I found among the other things the following:

(ww)  Dectc ....etc.  .NVIDIA (0):ACPI:[b] Error:[/b] Unable to find the brightness file path under /proc/ocip/video. The NVIDIA Xdriver will not be ableto respond to ACPI brigtness change hotkey events.

can this be the cause of the problem

Inside "kdm.log" and "dmesg" I don't seem to have found anything suspicious

II suspect that the driver video vers. 15 may have some problems with the 10.04, perhaps because the former is quite old. What do you think?

please let me know with which command I can update the driver of the video card? I knew of EnvyNG (envyng-qt) but this doesn't download/install anything because it can't find "envyng-qt" so do you know of any other alternative to evyng to install the video driver?

please do you have any suggestion ??
