What means "need-amd64-retrace "? It is quite annoying for kde users to have plasma completely dead. Someway to help???

[clickwir (clickwir)]

I'd like to help with testing or info gathering if I can. I upgraded from Jaunty on a production box and now have no KDE desktop. Had to install ubuntu-desktop to get something. It's clunky, but it's a workaround. I really need to get back into KDE though.

[Chai (isaiasmy)]

I solve the problem removing .kde directory, however it does not help to debug
the problem.

Isaías

Yes, renaming .kde does get me back to a stock KDE desktop. Somehow I feel that's the least graceful way this could be handled though.

I use Yakuake and have it start up automatically. Before removing the .kde, when I would get to a black screen I could still hit F12 and get Yakuake. It looked fine, window decorations and all. Same if I pressed Alt+F2 and ran Firefox. Worked fine, even composting, with the fading in and out, was working just fine.

When I try to start plasma-desktop manually (after it must've crashed in the background), I get these outputs:

QGraphicsGridLayout::itemAt: invalid index 0
QGraphicsGridLayout::itemAt: invalid index 2
QGraphicsGridLayout::itemAt: invalid index 6
QGraphicsGridLayout::itemAt: invalid index 2
QGraphicsGridLayout::itemAt: invalid index 2
QGraphicsGridLayout::itemAt: invalid index 1
QGraphicsGridLayout::itemAt: invalid index 2
...

which continue until it stops / crashes.

[Oliver Kastler (1730-gmx)]

Instead of removing the whole ~/.kde directory, I had to delete these lines in the ~/.kde/share/config/kdeglobals file:

[General]
BrowserApplication[$e]=firefox.desktop
XftHintStyle=hintmedium
widgetStyle=qtcurve

After that, all worked as expected.

[clickwir (clickwir)]

Oliver, thanks for that info. I rebooted today and KDE didn't show up again. Though, like before, everything started up fine and ALT+F2 would let me run apps and all. But your info saved me from having to delete .kde again and redoing all my settings.

From the same file, here's what mine said and that I had removed:

[General]
XftAntialias=true
XftHintStyle=hintfull
XftSubPixel=rgb

After removing that and rebooting, it works ok.

[Randal Barlow (email-tehk)]

The problem is qtcurve, on my machine at least. When ever I use that engine I crash instantly on login. Switching my theme fixes the crashing.

Repost from duplicate bug #433028

The problem is with the microblogging plasmoid that kubuntu ships as default. It has a little "configure" nag button which breaks with any non oxygen style. In fact any plasmoid that uses a QT widget, like OpenSocial, will have the same result. If you remove those plasmoids you can switch to other styles without a problem.

I can confirm - it is the default BLOG plasmoid that ships with Kubuntu by default.. Usually its the first thing I remove, but I had gone ahead and started messing with my font and theme settings before I did, and came across this error.. I removed the entires in the config file mentioned above under [General] - that got me able to get back in with plasma-desktop not crashing, then I removed the blog plasmoid, and re-enabled all my settings again.. and no crash, works fine ;)

[joseconsuervo (caseyshart)]

I agree with this as well. I wasn't really trying different things like
this, but this time around, I just removed all of the widgets, including the
microblogging widget, and have been able to add different widgets, change
settings, etc. without any issues. Every previous time, each time that I had
the crash, I had tried to configure the microblogging widget.

Fixed upstream for KDE 4.4. We should really provide the patch as a stable release update for the karmic packages, though: http://websvn.kde.org/?view=rev&revision=1062764

[Jonathan Thomas (echidnaman)]

Apparently the fix won't apply to the KDE 4.3 sources, so there's not much we can do. :(
It'll be fixed in 10.04 and in the KDE 4.4 packages for Kubuntu 9.10, though.

[bturrie (bturrie-yahoo)]

I'm having the issue in Kubuntu Lucid (10.04) . I'm looping in the login screen. I enter my username and password, see a white rectangle flash, and then bounce back to the login screen.

If I do a console login and then:

startx

all is well, so its more of an annoyance than anything critical.

In syslog I see

kdm_greet[1796] Cannot load /usr/share/kde4/apps/kdm/faces/.default.face: No such file or directory
