Well, thats very similar to my approach, when i got problems with gnome (usually minor ones): $ killall nautilus If your gnome is setup correctly nautilus should be restarted afterwars atomatically - and hopefully work again.

Re: [gentoo-user] unkillable processes
"kill -9 -1" should just kill all her processes, even the Xsession that she owns, and restart X. I would restart your manager (xdm, gdm) just to be sure. While you have your gnome locked, you could check what is running and if any process is defunct at console, so you would know wich app and/or gnome process caused the problem. I would bet in hardware issues like anyone before, but only if that happened to all accounts randomly (bad memory, processor overheated, faulty disk, etc), but as it only happens to her account, you must check software, and I bet (of course) Gnome. Try switching manager for her (KDE, Fluxbox, any) and see if it happens there too. -- Daniel da Veiga Computer Operator - RS - Brazil -BEGIN GEEK CODE BLOCK- Version: 3.1 GCM/IT/P/O d-? s:- a?

Re: [gentoo-user] unkillable processes
Do you and your wife have separate logons and if so, does this only happen when she is logged into her account using Gnome? In the past I've seen problems on my sisters' computer that sound similiar to what you've described and I've blown way the files that are created with Gnome is setup (this is on a box running Mandrake 9.2) the next time one of them logs in the files get recreated and this usually resolves the issue, and in times when it didn't work (because I just didn't seem to be hitting the nail on the head), I backed up their "stuff" (docs and so forth) created a new login for them, put their "stuff" into their new home and let them use it and if the problem went away, I'd just let them use this new login, or blow away their home dir and recover it with the copy. While it's certainly not elegant, it usually resolves their issues pretty quickly.

I think this is only true if you don't have any filesystems mounted on the disk, or at least no files in use. I've seen problems that required a reboot when I accidentally shutoff a USB disk that was in use. So it's not really the whole system that locks up, just anything trying to access that disk. Of course, if we are talking about the one and only system disk, well, the whole system locks up. -Richard -- gentoo-user@gentoo.org mailing list

Computer got crazy for ~20 seconds, spilled out a couple of screens with errors, but then resumed normal opperation and even finished copying files without any "hard-lock". Just marked that one disk as "failed" and went on. Maybe it was just a luck...

If it's hardware related only she can trigger it. 3) There were absolutely no messages in /var/log/messages or dmesg. The way this gets triggered is a bit unclear. She's working along and then does something that causes he desktop, but not Gnome pannel, to disappear. The machine is still alive. She can run Firefox but she cannot lot out. To get out of X we do Alt-Ctrl-Backspace. We then go to the console and see that there are about 7 processes left owned by her avccount even though she is logged out. We have found that for her to log back in successfully we have to kill all of these processes. If processes cannot be killed then when she tries logging back in she gets no desktop again. This only happens with her account. We have deleted he home directory and rebuilt it twoce. Eventually the same thing occurs. I suspect it's a bug in Gnome, or Gnome pannel, triggered by all the strangle little setups she likes to do to it with drawers and transparent things. Possibly it's a video driver issue?

Re: [gentoo-user] unkillable processes
Hi, As far as I know, this happens, when a process waiting for a hardware resource. Maybe something happened, which blocks the hardware, that means, the kernel process never returns to the userspace. This can be caused by bad/buggy hardware or buggy driver. So, Richard is right, check your hardware, does everything work fine or not.
