in [Setup]

Prev: Try this again: is Linux Linpus any good?
Next: which is better: mount an ext3 disk from windows, or write an NTFSdisk from Linux?
From: Nasser M. Abbasi on 1 Jun 2010 16:33 coming from windows to linux, I find that I miss the task-manager tool on windows. I am running fedora 13, and I like the linux tools below the desktop (shell commands) and all the other command line development tools, and that is the main reason I am moving to linux. But I am finding that sometimes some desktop applications hangs and something goes wrong. On windows, when this happens, I start the task-manager, find the process or the application, and kill it. For example, now I have firefox froze on me on fedora, I was in the middle of saving a page as web page. I know I can use ps -a, find the process id, and use kill, but sometimes that does not kill the process, and now when I did ps -a, it did not even list firefox ps -a | grep -i firefox even thought I started it, and I can see it there froze on the desktop. The point is, it would be much easier for new users if a task-manager like GUI tool is there (ofcourse, one must be root to run it?). I also have another GUI application which is hanged. Also xsane hangs up when coming up searching for devices, and kill does not seem to work on it. Is there such a thing on linux that new linux users could use? thanks --Nasser

Please note that a task-manager-like tool won't solve this or the other problems you describe. > The point is, it would be much easier for new users if a task-manager > like GUI tool is there (ofcourse, one must be root to run it?). If you have KDE, you can try ksysguard. From playing with it for about five minutes it looks like a very fancy version of top (plus what seem like some gkrellm-like features). You don't need to be actively running KDE in order to use ksysguard. > I also have another GUI application which is hanged.

This should be considered a last resort, but if you've already tried kill (which by defaults sends SIGTERM, or kill -15) then you basically have no other real options anyway. --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

In KDE, press Ctrl+Esc, in Gnome, you can add your own shortcut via settings->Shortcuts to open gnome-monitor. -- Gruß | Greetings | Qapla' Lieber BILD-Zeitung als gar kein Klopapier.

Real men don't reboot! ;-) Killing X may end up simply orphaning the rogue process, making it a child of init. It's worth a shot, of course, but the inevitable question will be "what happens when the process doesn't die after I kill X?" At that point you consider kill -9, or if frustrated enough a reboot. --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 |
