Re: complete system lock-up #2

First, and please, don't interpret non-responses as silence on the part of forum members. There are many times, when the situation described, and for which help is sought, simply isn't understood, or has not been experienced by those looking at the post, or the viewer doesn't have experience enough to provide an answer.

I seriously doubt that Kubuntu is giving you your problems. I would strongly suggest, that as a test, you use Konqueror as your web browser for awhile. Visit the same sights that you did with FF when the freeze took place. If you do not experience this same problem with Konqueror, then the culprit is most likely FF, or how it is interacting with certain web sites. That might point to missing plugins in FF.

Kubuntu is a fun distro, and stable as far as developmental systems can be. Most issues that people report tend to be with hardware that doesn't yet have fully functional drivers for use in the *buntu distros.

You will find help here. Don't give up just yet!

Ugh ... you may try to (re-) boot with the (additional) parameter acpi=off - or "revert" to Debian 4.0 ...

Hi there,
I did try Konq but it doesn't display a lot of stuff correctly. I use a lot of features on google.com and they just don't work in it.

Regardless, I don't see how any browser issue should freeze the entire box (or KDE or X, as the case could be)...that indicates a certain instability.

I'm hoping someone knows of a parameter to set with KDE/X/Kubuntu that would yield some debug info or let me break out of the lock-up when this happens again.

I saw the suggestion about acpi, but I need to know the logic behind that suggestion...is it just a wild guess or has it been known to cause these types of problems? What will happen if I turn it off?

Reverting to Debian is not an option...I didn't care much for straight Debian, which is why I decided to try Kubuntu.

Thanks for your help.

Re: complete system lock-up #2

ACPI causes a lot of things.

Here's a tip about getting support: ask why if you need to know, but don't refuse to do if you don't know why.

Re: complete system lock-up #2

I use a lot of features on google.com and they just don't work in it.

Could you tell us what those features are? Maybe we can reproduce them and find a solution that way.

As far ACPI is concerned. Well I shut it off, albight for different reasons, and it didn't harm anything. If you want to read more about acpi there a lot of posts here and on google.

Cheers

Sure, on the first occasion I was using Gmail, and on the second occasion I was using Calendar.

I know that ACPI is for power management...but I'd like to understand why disabling it could help. The system was not sitting idle when the lock-up occurred, it was actively being used. I do leave the system running 24x7, so power management would be a nice-to-have. I will go ahead and disable it, but I need to know why.

**SheeEttin** · Jul 06, 2007, 11:45 AM

Re: complete system lock-up #2

Because it might be causing the problem, that's why. ACPI does much more than power management.

If you need power-saving features, ACPI isn't going to do that much for you. It's things like turning off CRTs (or letting them go to sleep) that will save the most power. (Also putting the computer to sleep can help.)

OK, can you elaborate? Is there a known bug? Is there a documented history of acpi crashing or locking up ubuntu/X/kde ?

I am always skeptical when given instructions for no apparent reason. Please don't take offense. But it feels like the question is being avoided.

I have in fact rebooted with acpi=off. If the lock-up happens again, what are the next steps to try?

Re: complete system lock-up #2

I can only look at gmail with "Standard HTML" on Konqueror. Ive never used linux before, so I didn't know I could get like FireFox, or anything. Is there an IE6 for Linux?

**SheeEttin** · Jul 06, 2007, 02:10 PM

Re: complete system lock-up #2

It has been known to cause problems. This problem, I don't know. We're trying it to see if it fixes it.
Being skeptical is fine, but please, don't question every last thing. Nothing gets done that way.

firey, you can run Internet Explorer in Linux, but it's not exactly supported. (Not to mention difficult to get running and there are no guarantees about anything.) Firefox is in the repositories, if you don't like Konqueror, you can use that. If you like Konqueror, it's possible to get GMail to give you full AJAX; see this post on how to do that.

**firey** · Jul 06, 2007, 02:17 PM

Re: complete system lock-up #2

ok, thanks. Ive not tried any other browser on linux yet, as I have been having some trouble with Java, so I have been focussing on getting that up and going. Peopel are talkign about "Swiftfox" is it any good?

**SheeEttin** · Jul 06, 2007, 04:42 PM

Re: complete system lock-up #2

Swiftfox is nearly identical to Firefox. The only differences are that it's a bit faster, a bit smaller, and not all extensions work perfectly. (Most do, though.)

I highly suggest it.

Re: complete system lock-up #2

FF & Gmail / google calander work fine with me out of the box. I am running on a feisty with kde 3.5.6 desktop, my video card is a ati 9250 pro running the "ati" driver.

I know that FF has issues with some Flash heavy sites, but that is a adobe/flash player issue.

The only FF Plugin that is relevant is the gmail manager. The rest is stuff like addblock, tab mix plus, forecast, etc.

Yes I have acpi disabled, but that was for shutdown issues. It has worked up until now, and when I get the time I may read up a bit more on it.

So, either you have a different FF setup than out of the box or there is something else which I cannot define.

Sorry I cannot be of more help.

Btw if FF has issues, so will swiftfox.

Uh no, no it won't. I thought the same thing, but swiftfox does not crash when viewing flash on my machine. FF does every time. I am sure there are plenty of reasons why, but for those of us who are not programmers or advanced Linux users, swiftfox in lieu of FF may sort out some issues.
