things that kill KDE

[PattiMichelle]

So far I've identified 3 things that kill KDE - and I am back at the login screen after loosing everything: System Settings - both the Desktop Effects applet and the Application Appearance applet; and (of all things) the Cantor software. Did I somehow get a weird version of KDE installed? Is Compiz doing this?

Here's my sources.list - I don't know how to tell what version of KDE I have installed.
Thank You!!!!!!!!!!!!!!!!!!

Re: things that kill KDE

Not sure what your question is, but the way to identify your version of KDE, open system settings, click "HELP" at the top, then "About KDE". Should be 4.5.1

[PattiMichelle]

Re: things that kill KDE

Thank you - it says "Platform Version 4.5.5" - would that cause these problems? I just don't want KDE dying unexpectedly all the time and don't know how to troubleshoot.

Re: things that kill KDE

KDE v. 4.5.5 shouldn't cause these types of problems.

We need to know something about your history with Kubuntu:

1) did you upgrade to 10.10 or do a clean install?
2) what's your hardware like? especially video card if you're running compiz
3) how long after starting to use 10.10 did you start experiencing these problems?

[PattiMichelle]

Re: things that kill KDE

Thank you again very much for your time! I'm running on an HP dv7t-4000 laptop (1.6GHz, i7 quad core x 2, 8GB memory) with a dedicated ATI video card. I'm running the repo driver (Radeon Mobility 5000 series from "Additional Drivers"). It was a fresh install of 10.10 as this is my first foray into K/Ubuntu (x64). It is installed alongside Win7x64 and OpenSuSEx64I am also running Compiz, I think (should I disable that and go back to the default)?

It was not too long after starting using 10.10. I think my first problem was trouble installing the Singular backend for Cantor - then I started getting these problems with KDE and someone suggested upgrading to 4.5.5 and running Compiz. I think the problems went away then, but now are back. It seems odd because everything else seems to be running fine. I use this computer heavily for data analysis. It runs Amarok, Mozilla/Firefox, truecrypt, VirtualBox, IDL (ITT's Interactive Data Language) flawlessly.

I'm not against doing a reinstall/rollback type "fix" - but I would like to keep my layout and installed apps if possible. OTOH, if there are some commands I can run to locate errors in the KDE setup, that might be a good way to go. I'm at a loss at how startting apps can kill KDE.

Re: things that kill KDE

with xorg crashing, I definitely would try going back from compiz to Kwin to see if that helps things. In System Settings the desktop effects section is specifically for Kwin, compiz is not a KDE thing and has its own configuration tool, so attempting to adjust the kwin settings may be problematic if kwin isn't running maybe? Same goes for Application Appearance perhaps. Though it really should not be crashing. I have not used compiz in a long while, so I cannot verify this.

I wonder why someone would suggest compiz over KDE's native Kwin, unless you want many extra effects and their inherent propensity for instability :/, but imo kde 4.6 is quite a bit better all around from kde 4.5 and may be worth the upgrade (though natty 11.04 and 4.6 by default is just around the corner)

Not familiar with cantor or singular, but singular package is rather old version-wise (2008) and (assuming you are getting this from Ubuntu's repos) are not-well-supported automatic conversions from Debian packages. The software itself is from 2008, with minor packaging-related updates since then. it is entirely possible that something is missing or not working properly in *buntu for some reason for that package, though killing xorg is quite serious

Re: things that kill KDE

I use Cantor as a front end to SAGE, which includes Singular and MUCH more, with no problems. But, if I start SAGE from a console and then issue the "notebook()" command, a browser interface similar to Mathematica is started. Very Nice!! Very flexible. One can open multiple notebooks (tabs) at the same time.

Re: things that kill KDE

both the Desktop Effects applet and the Application Appearance applet .....

Is Compiz doing this?

You need to be careful trying to mix 'n match kwin and compiz. If you're using fusion-icon to switch cleanly between them, I think it can work, but I have not done that since 10.04 or earlier. AFAIK, if you want to use compiz, then you need to install the emerald window decorator to use with it.

Personally I have found the KDE 4.4+ desktop effects to be perfectly acceptable for cube switching between desktops, and the like, and have dropped compiz. Compiz does indeed have some fancier eye candy than KDE, but the added complexity and potential conflicts do not seem to be worth it, IMHO.

Re: things that kill KDE

Although I don't have first hand experience with ATI cards they do have the reputation of not so good Linux drivers.
Compiz (or any 3D type desktop) will likely make instability worse so switching it off should give better results.

You might want to upgrade to the 4.6 desktop, although older versions of software are sometimes more reliable a newer version is likely to have the more recent bug fixes.
http://www.kubuntu.org/news/kde-sc-4.6.1

I don't think it's the ATI card - I've had several that I've used with a few different distros of Linux, and they never had the habit of killing KDE when certain "vanilla" apps (and not others) start up. Usually it's much more devastating behavior.

Re: things that kill KDE

I guess the way to do this is simply to uninstall Compiz? Also, it was Cantor (from the repo) that is the other app killing KDE...

EXTREMELY cool to hear!!! I found a Singular back-end to Cantor and wanted to use that since I have read that Singular is pretty specifically the best Groebner Basis algorithm. I have a 356-equation Groebner Basis that I need to Solve(), but it crashes Maple (although maple is able to obtain the Groebner basis - it's the equation-solver that fails). Actually it doesn't crash maple, it just uses up all my 8GB of RAM and 8GB of swapfile. So I'm looking for a more robust equation solver...

That's why I'm frustrated with Cantor killing KDE...

OK, I found an app called Compiz Fusion Icon and fired it up. I chose "Use KWin decorator." Hope that fixes...

EDIT: That didn't help, neither did completely removing Compiz from my system.
Any more suggestions anyone?

Re: things that kill KDE

Still waiting to see the output of

lspci -vv

and

lsmod

so we know something about your hardware and drivers.

[PattiMichelle]

Re: things that kill KDE

Sorry, dibl - I missed that request! Wow, what a lot of stuff here. It amazes me that (almost) everything works.

So, it's an ATI HD5600, using the fglrx driver. I had such a lousy experience with an ATI card when I first started with Linux that I've been sticking with Nvidia ever since. But, you have your Google resource, and there are previous posts on this forum on this topic, and there is Ubuntu official guidance, and with luck one of our ATI users on this forum can even jump in and advise you.

One idea, the value of which I have no idea about, would be to rmmod your fglrx module, and modprobe the radeon module, and see if you get a better result with that driver. But, first check around and see if you can find something on Ubuntu forums about the HD5600.
