X.org Lockups

[fotisaueb]

Let me inform you for my latest observations

1)SSH HAS NOT relation to the problem

2)When kde crashes I run from an ssh session ps -aux where I see that X :0 uses only a small amount of cpu BUT as time goes by the cpu usage increases. I mean that the cpu usage increases 0,5 % every 3 seconds.(This is what hapenning to my system) It needs about 10 minutes to completly use the 99% of cpu.

3)PLEASE answer this. In my cases I notice that kde crashes only when I interact with it (mouse or keyboard clicks)
That means that NEVER has the kde froze without my interaction. For example watching video or other heavy processes will not freeze kde until I interact with it(a mouse click). Those cases can be when you click an application button ton launch firefox or when you select fastly files on file manager etc.
Some users can reproduce those lockups by pressing Ctrl and many times a mouse button.

What is happening on your system just before the lockup happens.Do you interact with it or a lockup can happen when you are away?

Way to reproduce the problem:On amarok collection options I have more than 50 directories of music when I click them one be one I always have a crash sometimes sooner (5th directory) sometimes later

I also have never had a freeze I have not triggered with a mouse or a keyboard.

- Writing in Konqueror's address bar. (the most common)
- Switching between browser windows, particularly but not necessarily while a page loads.
- Clicking refresh on a complex page, especially(?) combined with scrolling while it loads.
- Scrolling in JuK with the mouse wheel. (happened once, right after desktop change)

I'm not quite sure, but it may be that my freezes are never triggered by just one click. In most cases I have the time to write two letters in the address bar before it freezes, sometimes more.

It may be that I just don't use the kind of programs, like certain OpenGL screensavers, that are reported to cause lockups on their own. Indeed, I had GLX disabled for quite a while...

I don't know about ssh effects as I have nowhere to ssh from.

Also redhat has published a patch that disables the RendAccel option that means no 3d accelation at all.

More about the subject

A by the way a lot of users found a solution by setting AGP from 4x to 2x
Via chipsets are known to have problems with AGP 4x disable AGP 4x from bios

Well, I have been running 34 hours now without an xorg lockup/crash/etc. There hasn't been the slightest indication of one going to happen either.

It seems switching back to 2.6.10-gentoo-r7 "fixed" my problem. I looked over the links posted by fotisaueb, and it seems they all suggest turning this or that off, or using a non-nvidia driver (the proprietary version) ... but if a 2.6.10 kernel would make your xorg stable, it seems downgrading the kernel would be the better solution to me.

I went through jdgill0's diff and compared it to my two known-freezing configs for 2.6.10-r4 and 2.6.11-r4. I found nothing that was shared by my two kernels and jdgill0's second but not the first. So if jdgill0's system stays up I think we'll have to dig deeper than configs.

In that case I'd like to know everything. Your hardware, full kernel config, and xorg.conf come to mind, as well as any special options in BIOS or elsewhere. I'd like to duplicate your situation as far as possible.

But first I think I'll try your specific kernel release to see if that's the solution. Here are snippets from the changelog. Perhaps something in one of those three releases fixed the problem but for some reason didn't get into 2.6.11.

[trappix]

now that is odd, i did the same switch with no luck .. ive tried 2.6.10-r6(and r7) and neither have alleviated any degree of the problem, the hangs are still easily produceable and occur every time i start kde, my workaround right now is simply to use fluxbox.. somehow i have the gut feeling this is related to the new Xorg extensions, like the transparancy/fancy gui effects module, i didnt have any issues whatsoever until i started fiddling with that stuff.. can anyone with these crashes tell me about composite extension on their own setups?

[Nerdanel]

There are reproduceable hangs and random hangs. I and jdgill0 are having/had the latter form. It is unknown how much the problems have to do with each other.

[Gergan Penkov]

jdgill0 have you compiled inotify in the good configuration or it is in the bad one? Probably this is the only option which makes some sense in the diff.

Nerdanel,

You asked for some info like hardware list, .config, xorg.conf ... here is what I have .. if you need more let me know.

My hardware list -- don't think I missed anything:
-----------------------------------------------
SOYO SY-K7VTA Pro V1.0 motherboard ... I have done nothing to the bios -- it's in default config.
Athlon XP 1800+ cpu
768M of PC100/133 Ram.
Sound Blaster Live! sound card ... 3-4 yrs old, can't remember the exact model
Radeon 9000 Pro 128meg video card
Two ethernet cards running Tulip driver
5 hard drives -- all Western Digital
A generic cdrom
An I/O magic DVD burner

Here is my xorg.conf

[jdgill0]

Nerdanel,

If you just sent me a PM in reply to the one I sent you earlier, it seems the Forums automatically deleted it, i.e. even though I got the email for a PM, the PM does not exists

jgdill0, one more question, have you ever used framebuffer, because I see that you don't have it in this particular configuration.

[jdgill0]

[Nerdanel]

jdgill0, I didn't notice you had sent a PM for me before you told me. I am planning to wait a few days to see if my system is stable now.

[ctford0]

just a trend ive noticed looking back through the past couple of pages.....

Is anyone having this random lockup problem that isn't using xorg 6.8.2 or greater?

[jdgill0]

Well, here goes ... shoot me if you want ... I just experienced another crash

I made some changes to my system -- switched to using tmpfs for /tmp and /var/tmp. Anyways I rebooted all was OK, except I needed to move some KDE stuff out of /tmp, I was in konsole setting up the appropriate env variables in .bashrc ... saved that, switched to another virt desktop and BOOM CRASH ... logged in via ssh --> xorg at +96% cpu usage.

I explain the /tmp business just to be clear that I was doing something "semi-major" to my system ... but the crash had all the systems of the previous crashes -- I made it 60 hours without a crash.

Sorry people ... looks like I am back to square one again

Ok I've installed the new xorg, and there seems to be more debug info, but this didn't help me in starting kde. Gnome starts fine, I must try to freeze it now, but I suppose this will be an easy task:)
