Ubuntu :: Some Processes Not Started On Reboot
Jul 18, 2010
I've a laptop running 10.04 LTS 64 bit. (Upgraded from 9.04 64bit). Some times (1 over 3) certain processes are not started at boot time : bluetooth, vboxdrv, hddtemp, cups.... (I may miss some other ones). If I use sudo and the service command I can start them by hand and if I reboot they usually start automatically. I've tried to start the laptop without the "quiet splash" options to the kernel command line but I did not see any error messages nor anything more explaining this behavior. So I wonder where I can find where the glitch is, how I can fix it, and what is the startup sequence of an Ubuntu machine (there is no /etc/inittab, and the /etc/rcN behavior does not seem to be standard)

I've run into what is apparently an age-old SSH problem, which is that killing an ssh client process does not kill the remote process (unlike e.g. rsh). There seem to be lots of patches and a couple of open bugs on this topic that have been there for about 10 years or so... Having convinced myself by googling that there is no easy solution, I'm now looking for a workaround of some sort. I'm writing a testing framework so the processes I'm running remotely could be anything at all, i.e. I only have control of the client side. Also the remote processes are of course highly unstable and I need to be able to terminate them if they hang. ssh -t won't work for me as I don't necessarily have a terminal. Finding the remote process ID would be enough so I can do ssh <machine> kill <pid>, but I don't see any way to do that either. Just using ps, pgrep etc seems to suffer from not being able to uniquely identify the correct process, and killing the wrong process is of course very bad.

I have two script under /etc/init.d/ 'jboss' and 'client'. By machine-reboot these two scripts will be run. But what I want now is: The 'client' can only be run after the 'jboss' is successfully up.

I've installed the Apache Httpd Server on RH Linux. In order to start the httpd after the machine rebooted. But it failed.
I also check the /var/log/message but couldn't find any message about httpd. I have start the httpd manually. Now I can find in /var/log/message a message that "httpd started successfully"
My /etc/rc.d/init.d/httpd looks as follow. Can someone help?
Code:
#!/bin/bash
#
# Startup script for the Apache Web Server
#
# chkconfig: 345 85 15

Recently my GNOME (bottom) panel started reshuffling items after reboot.
I tried removing the panel, recreating it and placing new items on the panel. After rebooting the PC everything is undone. The panel reshuffles the items (even when the "Lock To Panel" is used). Also the items that are moved to the top panel, after rebooting return to the bottom panel.
Does anyone have a solution for this issue?

I have a startup script placed in /etc/init.d wherein I make the following call:
nohup sudo -u myuser $CATALINA_HOME/bin/startup.sh 2>&1
This causes Tomcat to be run as myuser, which is expected. However after issuing the reboot command the system starts up and root is now the owner of this process. How can I force the process to be started off as myuser on reboot?

I recently installed KDE in my ubuntu 10.10. To access KDE, I want to use
startx /usr/bin/startkdeBut using it disables sound in KDE (Sound is working fine in GNOME). It doesn't sound for anything like login sound, totem, mplayer or any other playerBut when I press Alt+Ctrl+F1 to change to virtual console, the playback resumes from where it was in time and when coming back Alt+Ctrl+F7 and the time in totem (or any other player) doesn't move. While log out also it doesn't play logout sound and doesn't logout, so I have to press Ctrl+Alt+F1 so that logout sound play then it exits.When starting KDE by kdm or gdm, the sound works normally. But I don't want to login again using kdm or gdm and not to use root user to start kdm or gdm.I don't know what is the difference between when KDE is started by startx or by kdm/gdm where the same user login in kdm/gdm as that for startx

I am using sda1 as /, which is a bootable drive. I do not know if my problem is that I did not create a /boot drive. After removing the iso dvd, I tried to reboot and I get this back: -bash: /sbin/reboot: input/output error Then it returns me to the terminal prompt.

I recently installed Ubuntu and I came across Conky.I was fascinated with this software and installed it using terminal codes. At first it rand with the default config file loaded. then i PC shutdown due to a power failure. now conky does not start and after searching over the net i found out that my conky config file is missing. I pasted the conky config fiel yet to no avail.
It gives me this error while running it in Terminal
Code:
Conky: /home/shazzy/.conkyrc: 30: no such configuration: 'on_bottom'
Conky: /home/shazzy/.conkyrc: 63: no such configuration: 'border_margin'
Conky: use_spacer should have an argument of left, right, or none. 'no' seems to be some form of 'false', so defaulting to none.
[Code]....
Here's the link to the site. I'm not sure how do i set this up as my conky config.

I've got a Macbook Air and a verified 9.10 liveCD in the external superdrive. I can successfully boot to the CD, but when I choose "try ubuntu without installing", all I get is a blinking cursor in the upper-left of the screen forever. Any idea why it won't start? CD works fine on my Dell, that's why I say it's verified.

I switched to Linux but I was, and still am a gamer, and I have been trying to get some of my favorites to run on Linux as well as find Linux native games. While this hasn't been hard, I have run into a sort of Brick wall. I'll get games to start, but there will be no sound at all. The game runs fine though. When I try to close the game, it crashes/freezes.
This has puzzled me because some games that display this bug now did not previously, and at first this only occurred on one game. Now it occurs on all games. I've checked around, found a few similar bugs, but the closest people seem to get to fixing it is "just uninstall pulseaudio and use something else". It only happens in games, music and other sound works fine.
As for specs, I must say I'm fairly ignorant of some things, but getting better, here is what I do know.
Mint 8
Nvidia graphics card (can't recall what model)
Gnome Desktop

Like the subject says, I was at my server and logged in directly and started screen. I then started a command and detached the screen.I then logged in remotely through ssh thinking I could resume the screen but when I try "screen -r", it says not screens to resume. I see the screen process still running and when I do go back to the server directly (no ssh) I can resume the screen and things are running just fine.Anyone know how to resume a screen remotely that wasn't started remotely?

Is the Server or Desktop version of Ubuntu a better choice for a home file (and possibly a media) server?
To explain a little, I currently have a WinXP Pro pc that provides file storage for the users in our home (spouse, kids, self). On this pc I have a windows program ACRONIS running to perform automatic backup of every ones stuff. This has saved me many hours of headaches when someone has a HDD or PC failure. Everyone in the household directs all of their downloading activities to a download partition where I have an anti-virus & anti-malware program monitoring all new entries. This too seems to have been a good decision over the years. I'm trying to sort out which version of Ubuntu will be the most logical entry point.
I expect the questions I am seeking insight for are the normal getting started stuff. Using several different search criteria, I did not hit upon existing threads for the topic If there is a more appropriate forum / sub-forum, please let me know and I will take this question (thread) there.

When I start Tomboy the applet comes up on the task bar and then it crashes.
I have tried re-installing Tomboy and Mono but it still happens.
I ran Tomboy --debug in the terminal and this is the output:

I have never touched Linux. Always been intrigued, but never toyed around with it until now. So please bear with me. I normally run Windows 7 Pro but would like to dual boot Ubuntu. I have installed Ubuntu 11.4 with Wubi 4-5 times, and it starts out fine, and then stops working on me. I tried recreating it to see what was causing the problem, but with no avail. The problem it has is as soon as I pick Ubuntu from the GRUB it boots to some sort of bootup (non GUI) and gets to a point where it says something about a system audit, and never loads from there. The only way to fix it is to uninstall Ubuntu (through Add/Remove Programs) and reinstall.
I am not in a place where I can partition drives or anything like that. I do not care so much about using Wubi, but either that, or help booting from a USB would work fine for my needs.

First said is the fact that I used Ubuntu 8.04 for over a year, alone on my PC, and there were no problems.
Few days ago I formated my PC, installed Win xp and immediately after I installed Ubuntu 8.04 from CD side by side with Win xp.
For few days everything worked more or less fine, but after few updates Ubuntu started crashing. The only way that I can work with Ubuntu is by choosing in the login menu something that is called Failsafe Gnome startup. If I choose this option everything works fine. I must add that I made no changes to my hardware except the fact that now I have Win xp installed with my Ubuntu.

I started a 'dd copy�ng' of one disk drive to another. Both disks are hooked to a remote machine and I initiated the dd command by ssh_ing into it.I have to shut down the box from which i initiated the ssh session.Is there any way I can keep monitoring the status (shell script)of the copy process, ie know when the dd command terminates and whether it terminated successfully .I could then ssh into the macine from another box and still know the status.

I've been using UNR since the 9.04 release on my Eee 1000HE and have been generally happy with it as a solution since then. Tonight I've upgraded to 10.04 using the package manager and everything starts correctly but when I start any application it minimises itself straight away making the system unusable. If I click on the application to bring it to focus, I get about 1/2 a second of typing before it minimises itself again. Using that method I've been able to get around the problem with a sudo apt-get remove netbook-launcher - but I like the netbook launcher and I'd like to keep using it.

I came home, having left Evolution running all day, to find it frozen and unresponsive. I killed it, opened it back up... and same thing. It opens, checks through my folders (I have one imap account, and one MH folder that Evolution dumps my pop mail into.) and freezes.
In the status bar, when it freezes, this is what it's doing:
Opening folder mh:///home/katia/mail;command=ssh%20-C%20-l%20%25u%20%25h%20exec%20/usr/sbin/imapd#inbox(...)
And then it just hangs.
If I disable my MH folder real quick, it doesn't hang and I can use my imap account fine. Re-enabling my MH folder quickly causes the hang again.
I tried opening the MH folder in clawsmail, but it hung also. Mutt was able to open it fine.

I have problem regarding when a application is started from the menu-line. If I for example start wxmaxima though Menu -> Science -> Wxmaxima, then the menu-bar is gone. I can access the menu-bar by pressing F10, but the menubar never shows up!
I have the same experience with emacs 23, where the menu-bar starts as it should, but whenever I change major (or minor) mode, the new menu-item appears, but I cannot access the menu-item (it is just blank). As before, whenever I go though F10 the menuitem shows up as it should.
Same goes for eclipse.
Instead of starting the applications though the Menu -> ..., I tried to start them in the terminal instead. Then the applications do not suffer from this menubar behaviour.

when I try to do admin tasks - e.g. setting my wireless connection to "available to all users" or updating a group's settings - it asks for "password for root" rather than asking for my password so it can sudo.I was forced to enable the root password, so I could do anything on my system ( sudo su; passwd; ) but I'd rather keep my root password locked and use sudo if possible.
