All of a sudden: System coming apart at the seams...

[oshunluvr]

Just as I was beginning to lament having no problems to troubleshoot: The oddest things began occurring this morning.

I am using 12.04, xorg-edgers PPS kernel 3.5.10-10 and nvidia 304.37 - and have been on that kernel/driver set for three days.

I was running Vbox with a win98 machine playing internet spades, cruising the internet using chrome (SR Iron version 19) and that's it.

List of issues:

1. First thing I noticed was chrome no longer had flash. Really weird because chrome includes flash. Indeed, the plugin appears gone.

I started searching the internet for a solution.

2. Then I went to my menu via Lancelot and noticed the menu background had changed to a dark-transparent rather than light-transparent which I had set.

I opened System settings and attempted to re-set the background.

3. After trying two or three themes to get back to where I was, the theme loader crashed and closed System Settings.

I went back to Lancelot to re-open System Settings

4. Lancelot crashed, and launched the backtracer.

I decided to log out and re-log in to see if this would help and noticed...

5. My system tray icons had reverted from the colored set I installed and prefer back to the ugly grey standard set.

6. The "Leave" dialog was totally different than before - It now shows a really huge power button icon where before was a small one.

Logging In/Out and rebooting did nothing to change all of the above back to previous settings. The boot went totally normal - no file system errors or logged problems. I haven't done any real trouble-shooting since I now have to go to work. My first thoughts are my user settings have become corrupted somehow but I certainly wasn't doing anything that would have caused that.

NOTE: This all happened within a couple of minutes. At about the pace you can read it...

Wow. Cosmic rays or sumthin?

Possibly related? I don't follow Chrome's development. Has there been an update recently? An update that perhaps broke Flashiness?

[GreyGeek]

It *might* have something to do with the fact that Adobe stopped supporting Flash on mobile yesterday.

It appears at least some of all this was coincidental or self-induced.

#5 (Tray icons): happened because I put the colored icon set into the default theme directory in my home. When I attempted to correct the menu background, the icons were changed back to the black and white set - FIXED

#1 (Flash): I am using SRware Ironbrowser based now based on chromium, not chrome. I needed to enable flash manually and all seems OK in that department - FIXED

Lancelot is still crashing immediately so I've had to revert back to Kicker. Theme changing seems OK. I'm really unsure if the log-out icon actually changed or if it's theme dependant. Also, since Lancelot has been crashing I'm logging out via right-click on desktop or cairo-dock logout which could be different than Lancelots log out - I just don't know and have no way to tell at the mo'. I've re-installed Lancelot after clearing my home settings for Lancelot with no change.

[vinnywright]

I'll try Lancelot @hear and see if it's logout is any different than cairo or right click on desktop (what I always use) or if it's crashing hear.

[vinnywright]

well hear Lancelot is displaying the same icons for log out, shut down , switch user,ect,ect as the system or rite click the desktop.

cairo on the other hand dose not display a thing when I click the logout icon .......LOL so go figure

I have Lancelot 4:4.9.0-0ubuntu2~precise1~ppa1 on KDE-4.9.00 as a widget on desktop-3 and so far so good (just installed for this)

Same versions here, but lancelot still crashing....

[vinnywright]

try purging it then reinstalling ??

VINNY

[oshunluvr]

Nope - still crashing. Weird

Here's what I get if I try and run Lancelot from the konsole:

stuart@office:~$ lancelot

[vinnywright]

this is all I get

vinny@Vinnys-HP-G62:~$ lancelot

load main catalog ###

and although I have a ~/.kde/share/apps/kabc it is empty (owned by vinny group vinny)

the rest

~/.qalculate/eurofxref-daily.xml

don't exist @hear

Like KRunner, Lancelot can load plugins. Some of those errors hint that Lancelot is having trouble with that. Purging the Lancelot package won't erase the user-specific config files it creates in ~/.kde.

Now here is something curiously coincidental. Over on the KDE forum, I found a post very similar to yours, Oshun...

http://forum.kde.org/viewtopic.php?f=67&t=97397

...except that it documents a person having trouble with KRunner, not Lancelot. Even the error messages are similar. Except the home directory in those messages is /home/stewart/, while yours show /home/stuart/. (......) The thread contains a bit of troubleshooting, perhaps something will be useful.

[oshunluvr]

Thanks Steve, yeah I saw that earlier too. Funny though krunner is fine. I logged in as my wife and Lancelot worked fine so it's clearly a config issue somewhere. I'll try and fix it on the 'morrow.

I have almost the same output, but lancelot is not crashing:

...

Try enabling kdebugdialog, and see if there's any interesting output
