Next: which is better: mount an ext3 disk from windows, or write an NTFSdisk from Linux?

But other than 2-3 times where things freeze on me, and I rebooted once, it is working well. I think it is the external USB disk not acting well, and that causes the file system to hang or something, but I am not sure yet. I think the USB disk goes to sleep, and the connection is lost and will not wake up again. Need to look more into it. The kernel also did a couple of hickups or internal faults (even though the PC kept running), and I got a pop up window to send kernel reports to fedora, so I click, send, and the report went. May be that will help someone. This is also a new PC, 64 bit, intel i-7 930. And the OS is 64 bit fedora 13. I am having such a hard time installing vbox 64 bit on fedora, I posted the problem description here today as reply to an article on linux daily web site: http://www.thelinuxdaily.com/2010/05/how-to-install-virtualbox-3-2-on-fedora-13/ and Derek at the TheDailyLinux has been helpful in trying to find what is the problem. --Nasser

I don't believe this to be unfortunate. What is unfortunate is when people misconstrue Fedora's purpose, expect it to be as stable as RHEL when it is specifically meant as a testbed for RHEL, and blame Fedora for not being ''as good'' as RHEL. (That doesn't mean we shouldn't blame Fedora when it doesn't work; it just means that Fedora users need to manage their expectations, and redefine what it means to "not work". I wish that the Fedora Project would be more explicit about the niche that RedHat intends it to fill; I suspect that many new users look at their web site and think, "oh, free, open, stable, looks great, I'll try it!") --keith -- kkeller-usenet(a)wombat.san-francisco.ca.us (try just my userid to email me) AOLSFAQ=http://www.therockgarden.ca/aolsfaq.txt see X- headers for PGP signature information

There's also: top My gnome has System -> Administration -> System Monitor which might be the tool you are seeking? But I usually use the cli for such things. Rgds Denis McMahon

In KDE, press [Control+Escape] - unless you have assigned another function to that key combination - and it'll bring up the KDE System Guard. You can kill any process to which you have the privileges, but of course, as a regular user, you cannot kill other users' processes or a root process. It's been a while since I've dabbled with Gnome tools, but "xosview" and "gtop" used to be similar. Don't know whether those are still around, though. And lastly, you can use "top" in a terminal window, which is not a graphical or mouse-driven tool but offers the same functionality. > I also have another GUI application which is hanged.

A default "kill" sends a SIGTERM to the application, but if the application has gone off to lunch, then this won't work. You'll then need to use SIGKILL, like so... kill -9 <PID_of_the_application> > Is there such a thing on linux that new linux users could use?
