After upgrade to KDE 4.9.3, no network and black screen after login

[veroslav]

Hi,

I am running Kubuntu 12.04 64-bit and yesterday I updated KDE to 4.9.3 through the Kubuntu Backports PPA. After the installation and a reboot, I tried to login, but instead of the loading screen (the one with the icons being displayed) I was met with a black screen and a cursor, which I could move. I was able to fallback to tty console (Ctrl+Alt+F1) and tried to see whether I could fix anything by updating/upgrading.

Unfortunately it appears that the upgrade left me without any network, as I am unable to sudo apt-get update nor to ping anything.

Could anyone shed some light on what might have happened and how I should proceed in order to debug?

Thanks in advance!

Kind Regards,
Veroslav

Anything else upgraded?

What does Ctrl+Alt+F7 (or F8) give you at that black screen?

[veroslav]

Thanks for the reply. You mean when I am already at the black screen or after I've switched to tty console? I tried switching backward and forward between the two (Ctrl+Alt+F1 and Ctrl+Alt+F7) and after Ctrl+Alt+F7 it always displays the black screen.

I don't recall there were other upgrades than KDE 4.9.3 itself, although I do remember I needed to perform the upgrade twice. The first time around updating from within update manager left me with some packages that could not be installed at that time. After installing what was possible, I tried updating again and then everything seem to install, as I could not see anything left to update in the update manager.

After this I rebooted and was greeted with the black screen as described.

I am suspecting that the kdenetwork package was somehow damaged but I can't figure it out.

[luckyone]

Ctrl+Alt+F7 or Ctrl+Alt+F8 should give you a logon that's not in X.
You might try xdrvr=vesa at the GRUB boot screen. Beyond that I'm probably lost.
What video card/chipset do you have?

[veroslav]

Will have a try, need to refresh my knowledge about GRUB boot parameters, so it will take me a while. I understand, I am really lost myself, upgrading to the previous two KDE versions (4.9.1 and 4.9.2) went without a hitch. It is an optimus laptop (intel/nVidia) and I am running with Bumblebee in order to disable the nVidia card.

Thanks for the tips so far, I appreciate it.

Try turning off your effects by pressing alt+shift+F12.

If you can get it back up you might want to try and revert back to the last KDE.

[james147]

Try:

sudo apt-get update 
sudo apt-get dist-upgrade
sudo apt-get install -f
sudo apt-get install kubuntu-desktop

[veroslav]

Thank you for the replies. Unfortunately, I am off to work in a minute but I will have a go tonight when I am at home.

james147, I've tried update, dist-upgrade and install kubuntu-desktop yesterday, the first two did nothing ( no packages to update/upgrade) and the last one couldn't install kubuntu-desktop because it didn't get any hits with the repository it tried to download from (I seem to be missing the network connection which prevents me from installing anything it seems).

I will try sudo apt-get install -f tonight, thanks.

Kind Regards,
Veroslav

Do any of your interfaces have IP addresses?

ifconfig -a

If the connected interface does not have an IP address, have you run dhclient on the connected interface?

Examples:

dhclient wlan0
dhclient eth0

[veroslav]

Hi again,

now I had a chance to perform some of the commands I was given in the previous replies and here are the results:

I've tried turning off the effects by pressing alt+shift+F12 at the login screen (can't reach the desktop) without anything happening.

dhclient wlan0 didn't result in anything and after I waited for a few minutes and restarted the computer afterwards, the situation was the same as before.

However, below are the last few lines of syslog after a system start and after dropping in and logging in from tty console:

For some reason it fails to connect to my wireless connection (my_con), it should connect to it automatically normally.
Can anybody see anything weird?

Thanks!

I should also mention that I tried logging in to the fail-safe mode from within GUI login. What happened is that I could briefly see an empty konsole window on the desktop and very quickly it went back to the login screen again.

[james147]

Wireless connection are made by network manager after you login... if you can I suggest pluggin in a network cable and running the commands I mentioned before.

If you cannot then you will need to configure the wireless network on command line.

[veroslav]

Hi james147,

I do have access to the wired network connection, will plug it in tonight and run the commands you suggested previously. I will keep you posted of the results, thank you.

Regards,
Veroslav

[james147]

Also, if you don't get an IP address when you plug in the network cable try running

sudo dhclient eth0

to request one from your router (though this should happen automatically).

Unfortunately it looks like the update didn't finish. In the code box above where you typed "sudo apt-get install kubuntu-desktop" there's a whole list of files to be updated/upgraded, then the messages start showing up about not being able to reach the repos. Apt does this when something doesn't get completed, it keeps the list, actually has some of the programs already downloaded, but doesn't install them until the whole list is filled. Now without the network access it can't finish. And a lot of the packages I see in the list have to do with the desktop, kde-workspace and kde-workspace-bin for instance. I don't know what the update manager did, but what I'm seeing in that code box shows me the update didn't complete. Apt-get would have nothing listed there if it did.

The wifi errors seem to indicate you connect through a secure connection, with user authentication and a password. It seems - I'm not real familiar with wifi - like your authentication isn't being provided to Network Manager. This line seems to point to that:

Nov 14 20:49:56 laptop NetworkManager[924]: <info> (wlan0): device state change: need-auth -> failed (reason 'no-secrets') [60 120 7]

If you have this at home, and have a wireless router, try connecting the computer directly to the ethernet port and see if that gives you a network again. If it does, try finishing the update through the terminal with apt-get.
