I was upgrading my system from 13.10 into 14.04 beta 1, but an error message caused the upgrade to be aborted and I was unable to do anything. After restart there was a message like: "kernel panic". I was even not able to reboot the PC using the power button. I removed the battery to shut it down.

In grub, I chose "dpkg" and it fixed the problems. However, now I don't have any window decorations & effects. How can I fix this problem? Thank you.

It sounds like KWin isn't running. Please try pressing Alt + F2, and entering "kwin --replace" and running that command. If you don't have the command runner enabled, start Konsole instead and enter "kwin --replace" there.

It activates for a short time then closes (i guess) immediately. I had Krunner enabled, by the way.

Well, your pictures look to me like you are using the upcoming Frameworks 5/Plasma Next (i.e. "KDE 5").
And that may be the reason why you have no desktop effects and window decorations settings.

Try to switch to KDE4 (on the login screen). Maybe you have to install it first.

And I guess you should better ask on a Kubuntu forum, since your problems apparently are caused by the fact that you are using a Kubuntu beta version.

KWin is running (see screenshot), but eg. the style isn't found etc. (actually using Win95 instead of oxygen is the only issue i can see)
/usr/lib/kde4/plugins/styles/oxygen.so is broken or dated (linking an incompatible version of /usr/lib/liboxygenstyle.so or something)

From the explanation of what caused this, I could only suggest to force re-install every package of the last update.

I checked LightDM, but there is only KDE Plasma Workspace is available. And it seems I have KDE 4.12.3 installed.

How can I force installation of every package again?

Someone familiar with Ubuntu will have to answer this (apt/dpkg certainly will have some switch and eventually the GUI tools also expose it - but I don't know)

I see. Can I check if /usr/lib/kde4/plugins/styles/oxygen.so is broken or not somehow?

it's not only about "broken" but "resolving an ABI incompatible library" - you could start by

strace dolphin 2>&1 | grep -i oxygen
(should tell you whether oxygen libs are accessed and opened)

Here is the output after executing the command you said:

http://paste.kde.org/pbqfavfxr

/usr/lib/kde4/plugins/styles/oxygen.so does not exist - at least it's not opened (only stat'ed) as it's supposed to be.

The oxygen.so-file is in Package kde-style-oxygen

Have you tried

Code: Select all

sudo apt-get install -f

If that doesn't works for you, try to reinstall some of the mainpackages, which will include kde-style-oxygen as dependency.
-> kde-workspace
or
-> kubuntu-desktop
Last one is a metapackage which contains the whole desktop with all programs and utilities as dependencies.

Why do you upgrade to a beta release?

Yes, this did not do anything.

I ran

Code: Select all

sudo apt-get install kubuntu-desktop kde-workspace --reinstall

and this solved the problem. Thank you

I've had a similar kernal panic on "restart" & "Shutdown" .
