How stable is Alpha 3?

Re: How stable is Alpha 3?

The one is the high cpu use from xorg and the system have much lag.

Do you see that with no browser running, or does it only start when you launch your browser? Which browser are you using? With or without flash?

The other strange problem is that sometimes my net connection hangs. I dont know if this is knetworkmanager problem.

Wired or wireless? It sounds more like a driver or link quality issue than a KDE or software issue. I don't think knetwork manager has any direct effect on the quality of the link --- that is done with firmware and the ethernet or wireless chip driver.

Re: How stable is Alpha 3?

Usually i work with chrome and flashblock but i have the problem with all the broswer. I use and compiz and i dont know if this done the xorg problem.
The network problem is a very strange. Before the upgrade the network works fine. Now when i login to the system for about 5 minutes i have very slow network and sometimes not at all. When i try to access one site from broswer the page do ages to appear and the lights on router dont flash.
After a while the net become normal. Ofcourse i dont havet this problem in windows.

Re: How stable is Alpha 3?

I would advise to turn off compiz, for the moment. With no desktop effects, and no compiz, let's see how your browser and xorg performs.

Re: How stable is Alpha 3?

Do you have any idea fro the internet problem?

Not really, but here are the questions that I would ask, to start troubleshooting:

1. Wired or wireless? Is the problem only one, or both?

2. What is the ethernet or wireless chip (whichever is the problem)? Discover it with

lspci

3. What driver is in use? Discover it with

lsmod

4. Check the ethernet setup with

ifconfig

the wireless with

iwconfig

and the quality of the link for each case with

ping [url]www.google.com[/url]

5. Does this problem exist in Live CD mode? Boot a Live CD to find out (Ubuntu or Kubuntu).

6. Does this problem exist with Live CD of another distro? Boot a sidux Live CD, a FC Live CD, a mepis Live CD, an ELive Live CD, or some other one, and check the connectivity. If you find a Live CD that really works great, check what driver is being used, and how well does it work (do #3 and #4 above).

I think you will learn a lot about the problem if you do these things, and maybe it will become clear how to solve it.

Re: How stable is Alpha 3?

I tried the latest LiveCD for nearly 5 hours one day. It ran beautifully. As mentioned here I had plasma crash once but it did pick right back up. I was impressed. As soon as beta is out, I will be upgrading all my systems then.

I cant check the problem with live cd because it happens for about 5 minutes and after is everything ok and then will appear again after hour. I try the dns solution but is not this. When the problem exist i try to go to router page and i see tha is up and running.

Re: How stable is Alpha 3?

That's odd -- I see no onboard ethernet controller in your lspci output.

EDIT: OK, it is the nVidia MCP55 "bridge". I recommend you google that -- for example, I found this:

https://bugs.launchpad.net/ubuntu/+s...ux/+bug/136836



How, exactly, are you connecting that computer to wired ethernet? OK, I see it now.

But, I also see:

in your loaded modules.

I think we need some more information -- this is not exactly a default Kubuntu user's desktop, is it?

Re: How stable is Alpha 3?

Nope.
It looks like he's used something like "GuideDog" to create IP forwarding and masquerading. That's an easy way to mess up your Internet connection if you don't know what you are doing.

Re: How stable is Alpha 3?

The only think i have done is to enable samba to access my files from internal network. I dont do anything else. And i have this distro almost 9 months with two upgrades with not other problems until the lucid upgrade.
I have done port forwarding only to my router and not to the distro.
Any solution for the problem?

[dibl]

Re: How stable is Alpha 3?

I can only think of 2 things that might be useful to do.

1. Open a Konsole window and run top or htop, then watch it when the network connections starts getting slow. See what process is rising to #1 position -- maybe this will give a clue on what is taking the resources.

2. When you have some time that's not too busy, boot a Kubuntu 10.04 Live CD (make it from the "daily build" site). Run it for 1+ hour, and see if the problem happens with the Live CD. If there's no slowdown, then you will know it is something about the port forwarding/masquerading setup on your existing installation. If that is the case, then I don't know what to tell you except make a new installation without the special network tweaks.

Re: How stable is Alpha 3?

thanks i will search it more . But i dont remember to edit or change something with the net connections. If it helps this the iptable list i take

I played with the daily LiveCD on 2/27 and was impressed... so I installed it!

Working great!

Re: How stable is Alpha 3?

I have found that iptable rules was from firestarter. I use this programme 4 years now. I try to unistall firestarter and i try to clean iptables with iptables -F. Nothing happens and the problem still exist.
I will try and the live cd to see if i have a problem and there

Re: How stable is Alpha 3?

In this picture you will understand the problem better. Is the network activity when i was download the kubuntu .iso

edit: ok the problem seems most difficult than i thought. I just use live cd and i find that works fine. I dont know what happen and what is break through the upgrade and i have this problem. I think is very difficult now to found a solution
