General :: Kill X Server Without Being Forced To Log Out?
Jun 9, 2010
I'm having trouble killing X server and keeping access to the console. I'm trying to install an Nvidia driver so that I can use OpenGL with Geant4. To install the driver, I need X server to be off.I Googled, and found a lot of things about runlevels that no longer apply in 10.04, since inittab has been removed, and that the runlevel now defaults to 2.
I tried CTRL + ALT + Backspace, but that just boots me to the GUI login prompt. In earlier versions of Ubuntu, I would set the default runlevel to 3, but since I'm already at 2, that seems to be as low as I need to go. I tried it in runlevel 1, but the installer warned me about the possibility of needing daemons that would otherwise be running. So in summary, I just need to be able to kill the X server and keep using the console on the current run level. If anyone knows how I can do that in 10.04,

Following Problem:I am only using Linux at university, so I'm basically beginner. Today for some reason after logging in the the power of the computer went off.After restarting and logging in again I couldn't start my firefox (which was running before).Now I don't know whether it is because I'm still "logged in" with the old account (since logging in on several computers/terminals is no problem), or anything eitherrivial or a real problem...Is there any way to find out if I'm logged in on another terminal, and if how can I close this one (external log out possible)

Ubuntu uninstalled OOo and installed LibreOffice. What a piece of ----! The first thing which showed up: bold, underline, etc don't highlight when selected; next- Open As, Save As don't show USB stick. I've messed with Linux enough--went downtown and purchased Windows 7--had enough of amateurville patting itself on the back and forcing non-refined software on

unclean shutdowns/reboots. Whenever I boot/restart, I notice the message "/dev/hdb1 (and hdb2) was not cleanly unmounted, check forced." Then fsck(?) scans them without errors, and everything continues normally. FWIW, hdb1 @ hdb2 are ext2, /boot & /tmp respectively, whereas all other partitions are ext3. Could that (ext2) be why? I checked halt, reboot, umountfs, umountnfs.sh, and umountroot in /etc/init.d, and nothing jumped out at me, though I'm not exactly sure what I'm looking at/for.

the process is mcelog. When I do as root kill -9 2323 which is pid of mcelog the process is not killed. I tried doing the same from top, press K and enter pid of mcelog. doing ps auwx | grep mcelog I see there are several results. I tried killing all of them like kill -9 2355 2341 3425 2345. But re-running the above commands still shows them as running. How else would I troubleshoot this to avoid restarting of the box.

### update ####
Sorry to waste the groups time on this one, after killing that and biting fingers, I re-examined the ps list and saw the tar and bzip running fine (so even though I killed the backup .sh, it was still going along, so I simply removed those and all was well again.
Feel free to reply though with #3, if I have 30G of mail, I know gzip is faster but bzip is more compression from reading, should;
a) tarring that mail actually drop to 3G total!
b) est (I know it's tough) but backing up 30G, is 10 hours longer than expected? (I will run some tests on a smaller folder)
############### end update
this is on an old RH9 box and backing up mail. I started the job last night in a shell script, it's around 30G of mail, and it was a tar using bzip as there was only 20 or so gig 'free space'. The old backup script was in perl and just a tar mail folder and the total was 3G so I figured I was safe.
Well it started last night and this am it was still running. I did a kill -9 on the pid and ps now shows it as;
root 9143 0.0 0.0 0 0 ? Z Feb23 0:00 [backup.sh <defunct>]
Disk space was down to 1.3G free (so somewhere all that space is being held temp somewhere), but I removed the old backup (3G which gave me a little breathing room of 4.5G), but the backup is still running somehow as the 4.5 is now 4.3. I tried the pkill, kill -9 pid, read someone said re-start the job which I did, then killed but nothing.
I really can't reboot this production box, so in RH9, I need to both;
1.kill that defunct backup
2.remove the temp storage it has made
3.figure out why it's taken 10+ hours and not done.
1 and 2 being 'critical'

We have an internal application which takes below 10% cpu usage normally. However sometimes it hit above 85% or more (and stays there) causing the server to become very slow. Currently we have to monitor this manually, kill the process and manually start it.
command / script that will kill the process (using pid will be the best option as i think) when it reaches 85% or higher
(I saw another question that suggested to use monit but I have to get this done using the standard commands available in the current installation - RHEL5)

Ever since I installed and started operating my FTP server, with a wired connection, my wireless connection to my computers has been going in and out a lot. My wireless connection is about a foot away from the router. Is it possible that the wired FTP server is pulling a lot of the internet signal away from my wireless setup?

I'm have some desktop computers sharing my Centos 5 server diskpace through NFS. From time to time, without any warning, lockd bugs and all the users that are using GTK applications like Firefox,Gnome.get stuck.
My first atempt is to restart the NFS, but locked files persist because I can kill the lockd pid process, even using root account , I suppose this is because it's a kernel process. Here is the message error I get when restarting NFS matrix kernel: lockd_down: lockd failed to exit, clearing pid

I'm running Ubuntu 10.10. I recently installed the open ssh server so that can sftp stuff. However, I do not want the server to always be on, only when I manually start So, I did an 'update-rc.d -f ssh remove'and now I don't see any startup scripts in the rcx.d directories any more.However, when I do a 'ps ax', there is always a '/usr/sbin/sshd' process running. I try to kill it but it keeps restarting under a different process ID.How do I disable sshd?

Ctrl-c doesn't always work to kill the current process (for instance, if that process is busy in certain network operations). In that case, you just see "^C" by your cursor, and can't do much else.What's the easiest way to force that process to die now without losing my terminal?
Summary of answers below:Usually, you can Ctrl-z to put the process to sleep, and then do "kill -9 process-pid", where you find the process's pid with 'ps' and other tools.On Bash (and possibly other shells) you can do "kill -9 %1" (or '%N' in general) which is easier. If Ctrl-z doesn't work, you'll have to open another terminal and kill from there.

This is a humbling experience for a long time MS admin/tech.I am wanting to build a file server fr my home network. So, I downloaded and installed FreeBSD 8.1 last night.Wanting a more familiar interface, I downloaded and tried to install KDE. It loads and asks for language. Then I select "Install kubuntu".
The kubuntu logo and a progress meter pop up for a while. Eventually the screen goes black and nothing else happens. I have to reboot. If I take the CD out it boots to FreeBSD.Am I missing something? Kubuntu never asks anything regarding partitioning. Is FreeBSD an os like DOS and kubuntu a GUI like Win 3.1 or is kubuntu more like XP with a GUI built in to the os? If it is the latter, how do I get it to kill the FreeBSD install?"Try kubuntu without installing" does the same thing.

I have a big problem with one of my processes named "mbusd" ;it is an opensource modbus RTU/TCP gateway when I plug USB to serial convertor to it my laptop without this process linux makes virtual ttyUSB very fine and when I unplug it it removes except some times (SOME TIMES not all the times) that I run mbusd process to work with, at that time during mbusd process work when I unplug USB/serial converter the virtual ttyUSB does not disappear and mbusd does not exit too and it turnes in something like this when I get ps -aux: mbusd [defunc] at this time I can not even kill it with -9 or -15 signals and pluging back the converter does not solve the problem too and mbusd does not exit or start to run again.
