[Solved] KDE not starting

[kln]

Hello, coming for help/advice again ...

I did a mistake (running a GUIapp with sudo or sth like this), had this classical problem (can't write to /home/user/.ICEauthority), tried to solve it, but it still didn't work, and after login, KDE starts to load but even before the 1st icon appears, black screen and back to login screen.

More detailed : I was running out of diskspace (100% full on home partition - ok, now I'm aware it builds up), I cleaned some old packages (apt-get autoremove/autoclean/clean as well as .thumbnails/large &/normal folder), but I did this with sudo dolphin. On next boot, "can't write access to */.ICEauthority".
I found out I could login in console and do startx with sudo (how bad is it to do this ?), then I thought stuff would come back to normal. I also did a $sudo aptitude update, and may have upgraded some packages, but I don't remember (I was unaware I was logged as root!).
Next boot, same problem. In console login, I tried several times (having stopped kdm first) to remove or chown to user .ICEauthority and .Xauthority. It then shows the right owner (user), but still no login possible (I tried stopping kdm and doing startx from the Konsole, and also rebooting and login from the login screen -- in order to have only one active login session as two maybe be impossible - is it the case ?).

NB: in /home, the folder /user is owned by user.

In this post http://kubuntuforums.net/forums/inde...pic=3113764.15, there is sth about var/tmp/kdecache-user. I deleted it, but it doesn't solve the problem.

Here is the /xsession-errors file, after unsuccessful login into KDE (I then made a copy of the file in console login).

Xsession: X session started for user at Wed Dec 15 01:53:32 CST 2010
QMetaObject::invokeMethod: No such method Konsole::Application::loadCommandLineOptionsForNewInstance()
x-terminal-emulator: Fatal IO error: client killed
konsole(1744) Konsole::SessionManager::~SessionManager: Konsole SessionManager destroyed with sessions still alive

Side question : is every file/folder visited when running as root turned to being owned by root ?
Still so much to learn, it seems ...

NB II: there are four security packages available to update. is it better to wait the problem to be solved rather than upgrading when logged as root ?

Thanks

Re: KDE not starting

I found out I could login in console and do startx with sudo (how bad is it to do this ?)

Yep, that's another bad one. :P

You are obviously the same personality type as me -- I always find the path through the woods by bouncing my head off every tree in the forest!

So, first you figured out that "sudo" can do anything he wants with the Kubuntu system, and you launched him to arrange things just as you wanted, eh? And now it's messed up.

Assuming you have fixed the "running low on space" problem, so you've got no more than about 90% of the OS filesystem full, and given the apparent state of desktop customization (not a lot, since you can't log in), I would say the quickest fix is to log in to Recovery Console, change directory "cd" to /home/kln, and then carefully remove the entire .kde setup with

rm -rf .kde

also remove the two hidden files that you already know about:

rm .ICEauthority .Xauthority

If you get a "permission denied" error on either of the above "rm"s, then that's the proof that there's root permissions on a file. Go ahead and use a "sudo" prefix to do the command, in that case.

then

sudo shutdown now -r

and let's see if you can get a KDM login that works. If you're still locked out, then the next step would be to remove all the hidden "." files in your /user/klm folder, which will nuke every setting you ever had. But it might let you initiate a new X login.

Good luck -- you're definitely going to master that system in the near future!

Re: KDE not starting

Yes, trying to figure out things as I go ... before asking for help also ...
but it can do more damage in Linux than in Windows !

Ok, so I log in to the console from the login splashscreen (that's not the recovery console, right ? getting to GRUB menu, I could only start in recovery mode, then DOS-like menu, but nothing was looking like a recovery console).
From this console login, I tried

$rm -rf .kde

but some stuff in it were still root-owned and I couldn't log in to KDE. So I had to

$sudo rm -rf .kde

and it worked. .ICE/Xauthority weren't a problem.
Reboot, but then I wasn't able to login to KDE.

Though BIG change now : if I do a console login, $startx works (without sudo). My KDE settings are gone, but that's not much of a problem. I tried to reboot again, but same pattern : I can only startx from the console login.

It's already a serious improvement !

Re: KDE not starting

getting to GRUB menu, I could only start in recovery mode, then DOS-like menu

OK, I suspect we're still struggling with some fundamentals here.

When you choose "Recovery Mode" from the Grub menu, you are logging in as root. On the "DOS-like" menu, if you choose "Drop to root prompt" you will get a command line prompt that looks like "#". Is that what you see? If so, you are root, and when you deleted the .kde folder, you only deleted it from root's home directory.

But, you said you had to use "sudo" to remove .kde, so perhaps you figured out how to log in and get the "$" prompt, which is your user's prompt.

Upon logging in, Kubuntu attempts to run the K Display Manager (KDM) service, which provides your X login screen. Try logging in to the command line, and instead of running startx, run

sudo service kdm start

and let's see what the error message says, or perhaps it will run and let you log in.

If it says KDM is already running, then try

sudo service kdm stop

sudo service kdm start

[kln]

Re: KDE not starting

I didn't choose the "Drop to root prompt" (you're completely right, I just noticed yesterday the '$' vs '#' command line prompt).

Instead of, I went to the login screen, clicked on the red 'shutdown' icon > console login, logged in, and deleted .kde & .ICE/Xauthority in /home/kalshyre (part of the .kde folder was owned by root).
I checked, .kde & .ICE/Xauthority are now all user-owned.

Now what you told me to try :
After having logged to the command line, I tried to stop KDM, but it was already running (the login screen). I stopped KDM, then started it again and it took me back to the login screen, but I still can't login (I enter password, hit enter, there's a flicker and then black screen and back to login screen).

Upon logging in, Kubuntu attempts to run the K Display Manager (KDM) service, which provides your X login screen.

Well, when I turn on my laptop, it goes as far as the login screen. So X is running, right ? And after logging into the console, I can only stop KDM -- so KDM was running too (and that was before logging in).

From the console, startx works, so the problem must lies with the login process when X and KDM are both running.

Re: KDE not starting

OK, boot your computer, attempt to log in on the KDM greeter, and then (without starting X) if you can navigate to /var/log/ there's a file there named Xorg.0.log. It would be good to see that, if you can manage to copy it out and paste it here. For example, you could shut it down with

sudo shutdown now -h

and then boot a Live CD, and copy that /var/log/Xorg.0.log file off the installed system on the hard drive (not the running Live CD session) and paste it from the Live CD session.

[kln]

Re: KDE not starting

I rebooted, tried to login from screen, then logged into the console and copied the file onto my desktop using

$cp Xorg.0.log /home/user/Desktop

Tell me if it is enough.

Re: KDE not starting

Good job!

Well, I don't see any problems, unfortunately. So you have an Nvidia GPU? What driver are you using?

[kln]

Re: KDE not starting

I have a GeForce 9600M GT, and the driver version is 260.19.06. It seems to auto-update (or to be included within the Kubuntu upgrade), because the last one I installed manually was 185.XX.

There's a new 260.19.29 driver just released on Nvidia's website, I'll install it and run aptitude update as well.

[kln]

Re: KDE not starting

Updating the packages was ok (but it didn't solve the problem). Then installing the new Nvidia driver was a bad idea ...
Now I have the 'Ubuntu is going to run in low graphics mode' and KDE cannot start in either way (login or console>startx)
From the low graphics dialogue box, I have access to a menu>fix the graphics settings (back to default configuration), I can then access the login screen, log in to console and startx, and KDE graphics are all messed up. I don't have access to Xconfig settings in NVIDIA X Server Settings and in Xlog.0.log, I it says 'failed to initiate Nvidia Kernel module'.
In fact this module is still at the old version (260.19.06) and the driver is now 260.19.29, and it says they should match.

So I'll try to go back to the older version -- it will take me some time to find this.
[Edit] found this, I'm on it. http://kubuntuforums.net/forums/inde...opic=3109491.0

Dibl, on the main problem, I haven't try the last fix you said, i.e. to delete all the hidden files in /home/username/ folder. Could it be possible to only chown the whole lot ? or to perform an advanced search to which one are root-owned ? Could the problem come from still having some root-owned files/folders in it ?

[kln]

Re: KDE not starting

Graphics back to normal
[couldn't install EnvyNG - though my system is in English, it gets packages through the French repositories, and EnvyNG doesn't seem to be on it.
Through K>System>Additional Drivers, I removed - by accident - the current version of Nvidia driver, then re-activated it. It took some time to download, but driver version is back to the ubuntu-supported 260.19.06]

Screen login still doesn't work - I'll keep looking a few days for what could be wrong before trying to delete all the hidden files in /home/kalshyre.

[kln]

Re: KDE not starting

I looked in /home/username/ for all the files with root as owner or group

$find /home/username/ -user root
$find /home/username/ -group root

and dealt with them (either delete or chown).

Deleted again .X/ICEauthority and rebooted, but I still cannot login from the login screen ...

The folder /home/username is itself user-owned.
/home and /home/.directory are root-owned (the only ones) -- should they not ?
Also my whole data partition is root-owned, but that seems normal.

Any other idea ? Is it still worth to delete all hidden folders in /home/username/ ?

[Snowhog]

Re: KDE not starting

Nothing - absolutely nothing - in your /home/username folder should be owned by root. So, open a console and ensure that your user is the one who owns everthing there. MAKE SURE THAT YOU ARE NOT OPERATING AS ROOT - VERIFY THAT YOU HAVE A NON-ROOT PROMPT ($) BEFORE ISSUING THE FOLLOWING:

sudo chown -R yourusername:yourusername ~

(replacing yourusername with you actual username)

[kln]

Re: KDE not starting

thank you Snowhog for help !
I did in this order (after console login - so not as root)

$sudo service kdm stop
$sudo chown -R username:username ~  (I was in /home/username/)
$rm .ICEauthority .Xauthority     (to be sure)
$sudo shutdown -r now

But I still cannot login from the login screen.

Outside of /home/username/ :
/home and /home/.directory are root-owned (the only ones) -- should they not ?

[Snowhog]

Re: KDE not starting

Outside of /home/username/ :
/home and /home/.directory are root-owned (the only ones) -- should they not ?

Yes. Those are properly owned by root.

Can you do a console login - boot into the recovery mode kernel option from the Grub menu? I'll assume you can. From the prompt type:

df -h

Look at the amount of available space on the / partition. You said you did some cleanup, but what is reported above as to how much space is available?
