Ubuntu :: PC Won't Boot After Disastrous Event
Jan 19, 2011
I was turning off my pc and my brother pulled out his sd card while the pc was shutting down. Now when I try to boot up I can't boot into my ubuntu partook it just hangs and then comes up with inittramfs. I can boot into my windows partition just fine. I also tried rebooting with the sd card in the slot but same thing. I managed to load up a live disc but have no idea what to do next if I want to save my old partition (if it can be saved) otherwise as a last resort ill have to overwrite the partition.

I have a program running on my server which I want to restart in the event that it ever crashes. Someone suggested "Watchdog" to me, but it appears to me that watchdog restarts the whole system, not the program. I couldn't find much documentation for it. Another suggestion I was given was crontab, except that I don't want to relaunch the program every 60 seconds, as it doesn't run on screen or anything, it forks itself into the background after launching it. Perhaps a bash script that would check to see if the program were running or not, and if it weren't, relaunch it? Not sure how to do that, I've never written bash. In any case, I just want to keep this program running full time.

Ever since 9.04 or thereabouts, I have noticed that it's impossible to change individual system event sounds in System -> Preferences -> Sounds. It only gives me a few lame choices of "themes". While it used to be possible to define my own sounds for startup, shutdown, new e-mail, etc, I can't find ANY dialog to facilitate this in newer versions of Ubuntu.
A question: HOW do I do this without having to hack apart my stock system sounds? There should be a way, but google and forum searching turns up nothing.
A comment: Ubuntu continuing to "nerf" their dialogs like this is infuriating, especially when the underlying system works so well. I actually don't know if Ubuntu or Gnome is responsible, but either way taking away rock-bottom basic functionality like this only hurts the OS and Linux's cause.

I use network-manager-pptp to connect to my VPN server. However, occasionally my VPN drops out (although my Internet stays up). I was just wondering how I could make the VPN drop-out trigger a bash script, for example playing a sound to alert me that the VPN has dropped?

I have posted this somewhere here before and solved it but can't seem to find it. Just waisted 50 minutes googling and checking man pages for upstart. By the way; are man pages written by someone using their tows to type and getting beaten by a stick for every character they type? It seems missing a lot of info. Anyway, I know smbd is started with /etc/init/smbd.conf and there is a line like:
Code: start on local-filesystems Now it needs to be started on? (manually) I can't seem to find any useful information but did seem to find the upstart man pages a hundred times or so (same info same missing parts). I would love to get involved writing documentation for these things if only I know what I was doing.

How to do so? For starters, I'm not sure there is such an event. Maybe it has something to do with the OS moving through certain run-levels

With /usr/bin/canberra-gtk-play set to --id='desktop-login' in the startup Applications dialog one expects a sound to play at login. This is not the case with fedora 12. I set the variable to --file=/home/me/sounds/myloginsound and I got sound.
I'm curious as to why the event id failed. I suspect that id was not linked/associated with any sound before fedora 12 was released. How does one troubleshoot sound event ids and their associated sounds in f12.
I'd like to get audio when I log out as well. I recall seeing a dialog box with events and associated sounds in f11 (or was it f10?) .... I don't see it in f12
1. Does anyone know which package adds that functionality?
2. In the absence of a GUI approach, how can this be achieved (with the terminal)?

I am on debian lenny and I am trying to make a script that will run in the background and checks the ethernet connection. If the ethernet connection goes down it will connect to wlan. I have found 2 ways of checking ethernet connection, via proc/net/dev and via ifconfig eth0. But if possible I want to avoid polling. So is there any event that is triggered when the table gets disconnect or at least the connection goes down and up?

I have a Logitech Media Play mouse with many buttons. I'm using xbindkeys to create some shortcuts to programs e.g. firefox, gnome-terminal--these work wonderful. What I cannot figure out is how to get the buttons to work for the media player(Ubuntu>System>Keyboard Shortcuts>Sound). I set shortcuts using my win key and letters, hoping to use xbindkeys to send out a keystroke. I have tried to use xmacro but to no avail. xdotool was not helpful, I think it may be outdated(desktop/workspace functions did not work).
My preferred option would be to get mouse events to keystrokes working with xbindkeys and program x(x being whatever works); however, just getting my media buttons to interact with the media play is my ultimate goal.

I know in windows xp there is a registry key and an entry in the Plug and Play log file as well as maybe an event id, that is produced when a device (say usb) is plugged in. My question is, besides /var/log/ (messages?) Is there any other location that that information is stored in?

My OS is F12 with Gnome desktop, after many alternatives I installed ns-allinone-2.34 so ns-2.34 run very well:
[dreams@localhost ~]$ ns
% exit
When I try nam, I got this error:
[dreams@localhost ~]$ nam
nam:
[code omitted because of length]
: no event type or button # or keysym
while executing
"bind Listbox <MouseWheel> {
%W yview scroll [expr {- (%D / 120) * 4}] units }"
invoked from within
"if {[tk windowingsystem] eq "classic" || [tk windowingsystem] eq "aqua"} {
bind Listbox <MouseWheel> {
%W yview scroll [expr {- (%D)}] units }
bind Li..."
I m not familiar with Linux so I don't understand what it means. I want to tell you that I can run nam when I access to the folder with this command ./nam and I can see the samples so I run simulation. I visit some pages when they speak about gcc and their compatibilities with F12. When I use Makefile I got access dined.

EDIT: I am now just looking for a way to multi-task in PAM, if at all possible.
Basically I would like to supplement replace my password based logon with and RFID scanner. The output of the RFID scanner looks like this:
Tag Read: 0a006f4757
Tag Lost: 0a006f4757
Tag Read: 2800c48994
Tag Lost: 2800c48994
As you can see I scanned some different RFIDs.
Basically I would like for my logon screen to wait until my script gives the message "Tag Read XXXXX where xxx is the RFID unique ID.
In case I lose my RFID, I would like to also allow me to type my password in.

I'm running Ubuntu 9.10. I'd really like to make an image of my entire system in the event of a mishap. I've found from experience that anything can happen with Linux and then you're into another reinstall. Anyone know of a good program or process?

I recently gave XFCE a try, after using Openbox for a long time and I really like it, so that I think I will switch totally to XFCE. All is working fine, except one thing: I really would like to have event sounds.
So I launched the Appearance-Module and checked under the Settings-tab both Enable event sounds and Enable input feedback sounds. Following the tooltip for the event sounds I also installed libcanberra, but I get absolutely no event sound.
[Code]...
I thought, maybe there is a lack of a sound theme, so I also installed freedesktop-sound-theme, but that didn't help. I did already searched with Google and in this forum, but have found nothing that would help me. I would be very happy if anyone can give me an advice what to check or has a link to a tutorial for this sounds.

$ cat /etc/redhat-release
CentOS release 5.4 (Final)
I've tried two copies of a: Microsoft Natural ergonomic Keyboard 4000 v1.0 Both fail. The result is my screen fills up with whatever key was missed. Re-pressing the key does no good. I have to unplug the keyboard and then plug it back in. So, I'm interested to know if this is a general problem or just my system. Meanwhile, I'm turning down the key repetition rate so it doesn't immediately fill my screen when it happens.....

I know that this not a Slackware question, but since Slackware 13.1 has XFCE 4.6.2 in its standard installation I just ask here. I have a problem with the event sounds in XFCE 4.6.2 on Debian Sid. I already have a thread about this problem here, and couldn't solve it till now. I need to know if this issue is related to Debian or to XFCE, before I ask at the XFCE mailing list. So just one simple question: Has any one of you that is using XFCE got the event sounds to work?

Before karmic while I was using Jaunty, I used to do it all the time, play my favorite sounds wherever I was them, startup, error, login, logout, etc etc... I found it in System>Preferences>Sound...
But when I do the same in Karmic, the opening dialogue box doesn't give me an option to change every sound specifically, instead, although it gives me option to choose a sound theme of my own. But for that I must first compile a theme and then install it / place it in sound themes directory etc etc.
How would I change sounds for particular events without having to compile a whole new theme (customizing the current Ubuntu sound theme)...
how do I create sound themes for Ubuntu and them install them in my Ubuntu?

Currently using a USB mouse, keyboard and the USB touch input from an Elo touchscreen connected to a Raspberry Pi (using the Raspbian flavor of Debian) through a USB hub and when I query the content of the directory /dev/input/ I get 4 "events" with each event designation associated with one of the input devices (the 4th one never seems to be active??).
pi@raspberrypi /dev/input $ ls -la
total 0
drwxr-xr-x 4 root root 240 Jul 29 02:20 .
drwxr-xr-x 12 root root 3300 Jul 29 02:23 ..
drwxr-xr-x 2 root root 160 Jul 29 02:20 by-id
drwxr-xr-x 2 root root 160 Jul 29 02:20 by-path
crw-rw---T 1 root input 13, 64 Jan 1 1970 event0
[Code] ....
If I examine an "event" characteristics using the linux utility "evtest" - example "event0" , I "might" get:
pi@raspberrypi /dev/input $ evtest event0
Input driver version is 1.0.1
Input device ID: bus 0x3 vendor 0x4e7 product 0x20 version 0x100
Input device name: "Elo TouchSystems, Inc. Elo TouchSystems 2700 IntelliTouch(r) USB Touchmonitor Interface"
[Code] ....
which is the Elo touchscreen.
But if I reboot the Raspberry Pi - I can also get for an evtest of "event0":
pi@raspberrypi /dev/input $ evtest event0
Input driver version is 1.0.1
Input device ID: bus 0x3 vendor 0x413c product 0x3010 version 0x100
Input device name: "HID 413c:3010"
[Code] ....
which is the USB mouse.....
It appears as if the assignment of the "eventX" identifiers (i.e. the "X") is arbitrary and it can vary with each reboot... which is problematic as I need to identify which "device" will provide the touch events for openframeworks. Is there a way to assign a specific device to a specific "eventX" designation ???
