Display issues since KDE upgrade.

[theAdmiral]

Hello, Everyone. I am back again.

Running routine updates tonight (or so I thought), KDE was updated to 4.2. In the aftermath, it has rendered the title bar of any windows or dialog boxes that appear in the upper left corner of the screen unreadable. In other words, I cannot see them because they are off the screen. Also, Firefox opens up in Normal view by default. I have not changed it, although I would like to figure out how. However, before I do, I would like to know why my Firefox window, or any other usually sizable window cannot be resized with my mouse--and how can I fix it? Anybody's help with this matter would be greatly appreciated.

Best regards,
theAdmiral

Nice to know someone else is having the same issues as me. I had KDE problems, had to log into root mode with recovery console and ended up accidentally installing 4.2. I have many problems as well. Hope somone has some ideas.

Re: Display issues since KDE upgrade.

Yes, many have had issues with the upgrade (there are about a dozen threads on it)...the cause is likely one of these (or a combination of them)

1. Using 'apt-get upgrade' instead of 'apt-get dist-upgrade' to upgrade
2. A package that is not part of the default installation (possibly third party packages) cause hickups in the upgrade
3. A packaging glitch (incomplete or wrong dependencies/conflicts in package(s))

There are a lot of instructions scattered around in the threads on this forum, but I'll give a brief summary of things known to work here (in order of smallest hammer to the largest):

1. Reinstall kwin (kde's window manager...responsible for drawing window borders among other things)

sudo apt-get --reinstall install kde-window-manager

2. Install kubuntu-desktop (in case it has been removed)...this should make sure everything is installed (although you may get back things you have previously removed)

sudo apt-get install kubuntu-desktop

3. Remove and reinstall KDE4.2 (This may remove things that you have installed, and you may get back things you have previously removed)

sudo apt-get purge kdelibs5 && sudo apt-get install kubuntu-desktop

This is just a summary, there are other things to try in the other threads you may wish to browse through...but the above have worked for others (though depending on the cause all of them might not work for everyone)

I can confirm reinstalling kwin fixes the problems you are having, at least some of them. I did a kwin reinstall this evening and now 4.2 is working well.

Good luck
