 Posted: Fri Feb 01, 2008 2:09 pm Post subject: XFCE4 flakey on AMD64 |
 |
|
Hi all,
I'm having those general intermittent untraceable problems we all know and love when using XFCE4 on AMD64, AMD X2 dual core. I'm running the same basic setup on my laptop, which is i686, and it's stable as a rock...
On the AMD64 machine, however, XFCE4 crashes frequently, read daily. Most often, it's the panel, or one of the panels plugins. Sometimes (about once a week) it's the whole of X. My girlfriend has installed a whole bunch 'o plugins, and she has the most issues, but I haven't managed to single out a specific plugin that's causing the problems.
So, has anyone else had similar issues, and has anyone figured out which plugins are stable/unstable?
Cheers,
James

Might it be caused by some "optimization", i.e. insane CFLAGS etc.? Maybe a hardware problem because of broken RAM, a CPU getting to hot or something like this?

lm_sensors reports sub 30 degree Celcius temperatures at all times ...
What's the best way to test the memory?
CFLAGS="-march=k8 -O2" (iirc, not at the machne right now, but they are generally resonable)

ok, if you can trust those values, it's ok.

The easiest way is to download a bootable ISO file from http://www.memtest.org/#downiso, burn it, boot with the cd and let it run at least several full passes (at least some hours). In many cases, a memory error will be recognized within some minutes - however, even it reports no error after some hours, it's no proof that there indeed is no error. I know several cases where a hardware failure was not recognized by memtest.

The easiest for me is to emerge sys-apps/memtest86. Then you can put it in your grub.conf and use it without a livecd. |

I prefer the live cd way - however, if you suggest to do it in this, you maybe should explain sirlark how "putting it in grub.conf" works in detail.

After emerging the package you get instructions with the concrete codes for lilo and grub. |

It's all good guys, I've a fair handle on grub etc... I just didn't know where to get a hold of memory testing software. I'll do the mem test thing tonight.
Is there a reason I shouldn't trust those sensor values?

It highly depends on your hardware. If the temperature of the CPU is measured by a sensor on the mainboard, then the actual CPU temperature might be up to 10 or 15 degrees over the temperature given by the sensor on the mainboard.
