How stable is Alpha 3?

[chris062689]

I've been away from Kubuntu for quite a while, and haven't been keeping up with it.
I've been using Chakra Project Distro, but it's just not getting stable enough for me.
I don't mind a few hiccups here and there, but I just don't want a distro that crashes all over the place. [not saying this happens in Chakra, but still....]

I know all about "Use at your own Risk", I've been using pre-releases of Ubuntu / Kubuntu for years now, I was just curious how "it really is."

Thanks!

ive been using since the start of dev cycle, with updates current my 2 laptops and 1 desktop are all running very stable. I've not had a serious system on either of the laptops. the desktop is a little more shaky with old nvidia graphics card but that is the only minor irritation. both laptops have been rock solid. kde is quite lovely now and can only get better. I highly recommend you at least try it.

I had been downloading and trying Lucid Lynx daily LiveCDs since the first of the year. I noticed a steady improvement in all categories as time progressed. After playing with the 2/27/10 Daily LiveCD for a couple hours I decided it was time to replace Karmic on all of my PCs.

It was a decision that I have not regretted. As I write this EVERY APP I have regularly used is installed on this Sony VAIO laptop and is running almost perfectly. That includes GoogleEarth, Stellarium, SAGE, QtCreator, bzr KDenlive, VLC, Audacity, Skype 2.1, FireFox K3b, Thunderbird, Kate, Kwrite, KMymoney, yawp (a weather plasmoid), KNetworkManager, PostgreSQL 8.4, PGAdmin3, Maxima, Step, gl-117, lincity-NG, and a host of games, Blender, DigiKam, GIMP, Inkscape, OpenShot (a new one I just tried), and many, many more.

The problems I've encountered:
Occasionally a plasmoid will crash, but they always seem to start right back up without intervention.
The detection of my HDA Intel audio chip was better in Jaunty and Karmic. They presented selectable inputs as two dropdown combo boxes, "Source 1" and "Source 2", to which I could attach "mic", "Line in", "Aux" or "CDROM". Lucid Lynx offers NO selectable inputs automatically binds the mic and the cdrom to a single capture control. I haven't plugged an external audio input device in yet, so I don't know if it would be automatically bound to that capture slider as well.

On my 5 year old Gateway m675prr laptop Lucid Lynx installed like a silk glove, with one exception: no sound. The ICH5 sound chip appears to be recognized, KMixer and AlsaMixer are populated with controls which slide up and down, mute on and off, etc..., but NO SOUND.

I just installed the daily build "Alternate", 5 MARCH version, 64-bit, this morning. Although I'm going to have to fiddle further to get an Nvidia driver installed on it, everything seems quite solid after several hours of beating on it here. Grub2 found my other OS and picked it up properly on the boot menu. No plasma crashes so far, Dolphin works as advertised, strigi did not take over my computer, boot time is nice and fast -- my first impression is that it's as least as solid as 9.10 was yesterday.

[ubersoft]

I'd say that for an alpha it's extremely stable... but it's still an alpha.

I have just replaced karmic on my desktop with lucid today and no major issues so far. Immediately after the install i went to nvidia site and downloaded the latest drivers for my 8800 card but could not install it. On a whim I navigated to system settings/hardware drivers and asked to activate the latest nvidia drivers and after rebooting the PC I was pleasantly surprised that it had installed the latest nvidia-linux x86 -64 195.36.08. Now need to activate coolbits, crank it up and go annihilate the baddies in alien arena.

;D

You go, assettt, and may the best man win!


p.s. If you really want the latest 195.36.08 Nvidia driver, I just posted how to do it here (http://kubuntuforums.net/forums/index.php?topic=3110389.msg221229;topicseen#msg221 229). Or maybe after you've used the Hardware Drivers deal it will not be blocked by the nouveau driver.

Dolphin works as advertised,


Does it EVER! The more I use it the more I love it.

I noticed that as well. When I started up LL on this Sony VAIO the first msg I got was strigi "indexing ....", but it finished faster than I could uninstall it ... but I uninstalled it anyway, and that database that Canonical is stuffing down our throats, "vurtuoso".

Hi,

being using Lucid since the first day.

It's going very stable except kontact. I spent 90% of my working day reading and writing emails and i use 3 imap servers. I guess i still have to wait until SC 4.2 ::)

Either than that, it's working really great ( except maybe some nepomuk weirdness once in a while ) and running very stable.

keep the Good work, kubuntu team

[assettt]

As others have said, lucid seems to be pretty stable with fast loading and indexing really fast. The only thing I've noticed in the last 24 hours is sometimes after restart, compositing takes too long to be enabled and will get suspended, but only really affects desktop effects.. Usually will be fine after a reboot.

Quote from Dible

Dolphin works as advertised


kdesudo dolphin
works as well?

See:
http://kubuntuforums.net/forums/index.php?topic=3110102.new;topicseen#new

Only:

kdesudo 'dbus-launch dolphin --nofork'
works for now.

Otherwise LL is very cool :)

[dibl]

Ooops, you are correct -- the kdesudo dolphin command does not work correctly. I had not tried that one. All of the file and network browsing functions seem to work right for the user, however.

[dibl]

Ooops, you are correct -- the kdesudo dolphin command does not work correctly.



Well, that was yesterday. Today, after running updates, (and noting my system has 17 hours uptime), I did Alt-F2 "kdesudo dolphin" and here is what I see:

I guess they fixed it! :D

[Snowhog]

Hopefully that means the fix will be coming down for Karmic as well. Just tried again, Alt+F2 kdesudo dolphin and nope, the file protocol death is still present.

[vista killer]

I have two problem. The one is the high cpu use from xorg and the system have much lag. The other strange problem is that sometimes my net connection hangs. I dont know if this is knetworkmanager problem.

[dibl]

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.

[vista killer]

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.

[dibl]

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.

[vista killer]

Do you have any idea fro the internet problem?

[dibl]

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 www.google.com

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. :)

[MoonRise]

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.

[dibl]

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/+source/linux/+bug/136836

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

[GreyGeek]

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.

[vista killer]

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]

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.

[vista killer]

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! ;D

Working great!

[vista killer]

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

[vista killer]

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

http://img33.imageshack.us/img33/4100/netconnection.png

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 :(

[GreyGeek]

It looks like your download speed is capping out at around 750 Kb/s.

When you do an identical download using the LiveCD is your download speed also capped out at 750Kb/s ??

Nice graph! How did you do that?


Yes, I think you are going to do a new installation of 10.04. Whatever you did with Firestarter and port forwarding and Masquerading, over the past 4 years, has caused some problem and I don't know how we would ever figure out which tweak was the bad tweak at this point.

He installed the network plasmoid on his desktop and set it to show only the eth0 port. When only a single setting is used the graph of activity looks like that.

Cool! I might try that just to see what it looks like on my end.

[GreyGeek]

Here's what it looks like on my notebook:

[vista killer]

you can see the problem in the left area when the network hangs for a while. I notice that when the network hangs i cant go and to router ip. I think i am one step before new installation and this is the last time after this years for alpha upgrade.

[MoonRise]

Have the Daily Build Downloading now @ work. Once I get in I'll burn it and try it on my laptop. If all seems even better, then Woo Hoo I will install. My laptop did SOOOOOO much better under Lucid Alpha 3. I hope it doesn't change.

[vista killer]

Ok maybe i have found a solution for my problem. The problem finally seems to be from ipv6 and this bug

https://bugs.launchpad.net/ubuntu/lucid/+source/eglibc/+bug/417757

i have disable the ipv6 with this command


echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6


and i have edit the /etc/rc.local file and write there the command.
This seems to be work for me and the net connections is ok now. Questions..

Is there a better way or command to disable ipv6?
Do i have to report to launchpad this bug?

[vista killer]

Ok this was the problem. Half hour now with broswing and i dont have the problem anymore :D. Thanks all for the support

This one is among the plasmoids by default >systemservices > System - network

http://bayimg.com/image/halfaaacc.jpghttp://bayimg.com/image/halfjaacc.jpg

As for alpha3 I haven't had any major trouble since the xorg (was it?) trouble in late alpha1, any other trouble more then minor has been self inflicted for educational purpose ;) Hardly any desktop crashes anymore either ( I keep the karmic install as a safety line tho, not as bold as GG ;) )

[Fintan]

So it is not network plasmoid ;)

Thank you for that. :)

[PJJ]

Same experience here.
Almost all issues or troubles were created by my tinkering, though there are a few Lucid made things that need fixing.
I am using LL as working OS with an up-to-date backup of Karmic and data on a separate drive that can be accessed from both operating systems - just in case.

[maestrobwh1]

Flawless... I mean, seriously the best Kubuntu yet. Running mine on on an older ibm thinkpad t43. 1.6 GHz Celeron with 2 GB ram. Januty was "ok" Karmic as a bit faster.

Lucid: I feel like I got a new PC. Even with desktop effects enabled (minus a few animations), it still is snappy and crisp. Boot time? Poof... up and running in well under a minute.

Occasionally an app will crash. Occasionally.

And GTK apps look like they belong on the desktop. That always bugged me. I like banshee for ipod support, but never liked how it looked. Now one would never know it is a "non native" app.
