Ubuntu Multimedia :: VLC HTTP Interface: No Sound When No User Is Logged In
Dec 20, 2010
I have a pc where I run ubuntu 10.10 and on this pc i have installed vlc and on boot i start the vlc http interface. Therefor I created the file /etc/init.d/vlc. The file seems like this:
[URL]
and I also updated rc.d. Vlc starts on boot as desired I also can send commands like in_play the file (a playlist) is loaded and reguarding the status.xml the file is played. But when no user is logged in I hear no sound. When I perform a login on the machine there is first still no sound but when I send e.g. the pl_next command or call in_play again then there is sound. Sadly the pc shouldn't be attached to a monitor and therefor I can't perform a login everytime so I need sound, when noone is logged in. Why is there no sound?
when I log in, I can move the mouse, but nothing else. The whole user interface is unresponsive and absolutely no keystroke works. It is probably not because of my hardware (hp 2710p) because logging in as root (with only slightly different Gnome configuration) does work well. I assume it is because of some error inside the Gconf. There is always an error when starting Gnome that an entry could not be read, including some bunches of ~30 question marks. If it is useful, I can give you the whole message literally.
I haven't changed data inside Gconf, but I did have it open when I was installing a program, and then the console did show the message with the question marks for the first time (while processing some "trigger" post-install). I think the program I was installing was drapes (for changing desktop wallpapers in Gnome). Strangely Gnome did startup correctly afterwards for a couple of times (always showing the above-mentioned error). I have no idea what change made it suddenly stop working yesterday.
The differences in Gnome configuration between the working root and the unresponsive user account are, as far as I can tell from memory: changed theme (elegant-brit), wallpaper, fonts, globalmenu in the panel, installed - added to panel - uninstalled drapes.The rest is the same for the root account. I can still log in to the shell as the normal user, but "startx" leads to the disabled graphical interface. As I said, the graphical interface works well when I use the root shell. I can't access the internet from the user shell unfortunately (if I need to, I will figure out how to set up wlan in the shell).
this never seems to happen on my main admin account, but on the second user account sometime after i log in sound stops working. ive checked the Comprehensive Sound Problem Solutions Guide and my sound chip shows(onboard). what should i do to try and solve this? also i was wondering if there's and ubuntu equivalent of silverlight?
I have a ELRO C903ip.2 camera. I want to use it on zoneminder but am having trouble connecting. I have set a basic account of visitor with username and password both set as visitor.
The question is what is the syntax to the cameras ipaddress via http passing the u/n and p/w at the same time as part of the http string? I have tried the web page: [URL] .... to no avail, i must be missing something pretty obvious but just can't see it for looking.
I recently got a new audio interface, which is working perfectly on ubuntu 10.04 i just plugged it in and it worked without any tinkering! the interface is a lexicon omega which is fully supported under alsa. The problem is that for some reason it's not working on ubuntu 9.04 (which is where were most of my work currently is so occasionally i still have to use 9.04 as i don't have all of the same software installed on 10.04).
Jack seems to detect it properly in both 9.04 and 10.04 as it is listed in "interfaces". But it does not show up in "Volume Control Alsa Mixer" so I cannot select it from the drop down list.
So currently I have no sound (just in case you weren't able to decipher that from my primitive ubuntu-speak above )
I've got a custom compiled kernel, just built on Lucid 10.04 from the kernel sources.System works fine, except for sound.When I log in as normal user and try to play a wav file using.The sound file is being played, but I hear no sound.However, when I do "sudo -s" and become root, execute the same mplayer command then I can hear the sound.My Sound preferences shows no input device and only "Dummy Output" as output device.On the generic kernel as came with the Lucid 10.04 CD, sound preferences shows different devices.The strange thing is: when I compiled my custom kernel, I changed nothing to the sound options in the kernel config file.
I updated Lucid yesterday, and when I restarted the user interface was changed to a more simple feeling display. This makes me think I'm stuck in a "basic" mode or something. I attached a screen shot, but to give you an idea ill describe some issues. For one thing the minimize buttons are now on the right. The volume control, which used to appear on the top right of the screen, is gone and my multimedia volume control buttons on my Inspiron 1420 no longer work. Furthermore, the command terminal is now white and the keyboard shortcuts for copy and past don't work.
Immediately after updating I also got an error message at login (which also appears different and gives options on bottom of screen like gnome Failsafe) which said something like "gnome default power management installed incorrectly...". I followed the advice of a forum thread that involved the purge command and that seemed to remedy that message.
I can connect to the HTTP cups interface (localhost:631) but if I need admin priviledges, giving my id/pwd doesn't work. I don't see any "cups" group defined.
Otherwise, how do I enable a printer? I could disable it using the KDE printer management interface, but I can't re-enable it using same... Answer: /usr/sbin/cupsenable
I have an external audio interface that is supported by alsa and works really well with ubuntu 10.04. The only problem is that on my studio monitors I can clearly hear that the sound from ubuntu is distorted, like there is too much gain somwhere. Since my audio interface (Lexicon Omega) has an output level knob on the interface, ALSA does not have a level slider (software) through any mixer (eg GNOME ALSA mixer).
In order to stop the distorting sound problem, ie the signal input to my external audio interface is too "hot" first install PulseAudio Volume Control (referred to as pavucontrol in repos) in PulseAudio Volume Control configuration tab, set "profile" of your external sound interface to "off" log out, and when you log in again your problem should be solved.
How come you can shut down or reboot from the gui w/o needing root privelages, but if I enter "shutdown -h now" on the command line I am met with "shutdown: Need to be root".
Also- somewhat unrelated to my first question- I recall when I first started Ubuntu-ing, if I wanted to shut down or reboot while another user was logged in, I'd need to enter my password- but it doesn't do that anymore. Two users can be logged in with multiple applications open, and if I reboot or shutdown, it just goes for it? (using 9.04, for now...)
I have a very annoying problem with my Lucid (installed with ubuntustudio's alternate dvd). Two out of four times when I log in my account has some restrictions. I can't mount devices on nautilus and the shutdown button won't be displayed. If I log out and log in I see the restrictions again. Only restarting (with "sudo shutdown -r now" or so) may give me a normal session. On the console works everything normal. I mean i can sudo with my password.
I am trying to login to a redhat server via VNC. This used to work until I reloaded the box. Although I had previously logged in directly to the box, then I could vnc to it remotely. The service is running, netstat states the ports are open and listening.I can ssh to the box, and ran the usual commands to start the services.So my question is. Do I need to have a local user logged in before I can VNC, if so how can I do that via the command line.If this is not required for a local user to be logged in, what am I missing. Other than VNC, which other services do I need to start.
I'm running a VM (headless), and sound only works when I am logged into a gnome session. Sound (from any application, including VLC running in a terminal) is stopped when I switch user. How do I prevent this from happening?
IF - a logged-on user wasn't properly logged off - the system is restarted - the same user attempts to log in

This seems repeatable, and happened on 2 different PCs.
When logged into Gnome as another user and trying to sudo a backup of the borked user's home before attempting a repair, a ".gvfs" file is reported "in use" and can't be copied.
It happened to me quite a few times, due to crash or more often power failure, or my sudo-errors. I now keep a few spare virgin sudo-enabled cloned accounts just in case one dies that way.
I recently installed FC14 as my server and is able to ssh and vnc into the server when locally logged in. If i logged out (at login screen) then i cant ssh or vnc into the server. It is pointless to have a server if i am not able to remote in via ssh and vnc.
I have recently installed Opensuse 11.4 on my desktop. And also upgraded my gnome-2 to gnome-3. Its works nice and I am enjoying it. Only the biggest problem I am facing is, if I lock the screen and leave my desk for couple of hours then user gets logged out automatically. Which is resulting all the documents and applications gets closed. I am unable to work in my desktop now.
I am running a mail server with combination of dovecot,sendmail and squirremail as web client. I want to change the password of the user if he/she not logged in for 21 days.
I cannot find a post that matches this scenario...the id created during the install (from CD) of Karmic has fully usable sound. However, users created from the Users and Groups app do not.
I have made sure that all users are defined to the audio, pulse, pulse-audio, and pulse-rt groups. No luck.
I have followed every step I have read having to do with the alsamixer. No luck.
I have verified that alsa and linux itself are at the latest versions.
My problem started when I updated Ubuntu 10.10 developer release (or whatever it's called ) to Ubuntu 10.10 Final. When I switch user or lock the screen and log back in, my computer makes no sound. I know it's not muted since I can see that in the volume control. The only way I can fix it is by restarting my computer
Quite some time ago I managed to get sound working perfectly on my DELL Inspiron 1720 under openSUSE 11.2 and KDE 4.3.5. Then suddenly some months ago for one of the four regular users on my system sound stopped working! KMix is always muted after KDE session startup for this user and even if you unmute it there's still absolutely no sound; in particular, the commandspeaker-test -c2 -l5 -twavdoesn't generate any sound (while I do see the printed output which doesn't contain any error messages). Even if I su to root in the very same Konsole window speaker-test remains silent!
Since sound is OK for the three other regular users I've already compared KMix settings as well as System Settings > Multimedia for each of the regular users but found absolutely no differences. BTW: In System Settings > Multimedia I have XINE set as the backend and "PulseAudio" has priority over "HDA Intel (STAC92xx Analog)" for all sort of audio output, and - perhaps needless to mention - all the four regular users are members of group "audio".
$ who -a system boot 2010-09-06 09:48 run-level 2 2010-09-06 09:48 last=
[code]....
looks as though this is the culprit, but...
$ kill 5485 -bash: kill: (5485) - No such process
This process doesn't exist in the /proc folder or the output of ps. Does anyone know how this happened, and how to remove this ghost user from my system without a complete reboot? I think I have seen a similar thing on a RedHat machine ages ago but I have never figured out how to log out these ghost users.

on my netbook I've tried to make possible for my user to shutdown without needing a password. battery could run low when I'm not in front of it. Editing sudoers has allowed my user to shutdown the system, but Gnome still prompts me for the root password whenever root is logged in too. That's usually the case, because to avoid entering the root password multiple times whenever I need elevated privileges and not wanting to cache the root password, I keep a Root Terminal always open.
I'm looking for a user-friendly way to change the password of a user that is *not* currently logged into the machine. We have a machine that is used by a number of users with a low level of tech savvy. The machine gets logged in as a generic user which works for most purposes, but due to a management requirement, we need Firefox to be run under an account set up for the individual user. I've gotten that bit to work fine, but what I can't figure out is a friendly (GUI) way to allow users to change their own password while the machine is logged in as the generic user. I would like to use gnome-passwd, but I've been unable to figure out how to get it to run for a user other than the logged-in generic user.
Is possible to send a message (popup window or something) to local user logged into X (xdm, fluxbox) from console ? For example: user1 is logged and using X/fluxbox, user2 logging into the same box by ssh to console. Now - what user2 have to do to send message to user1 ?
I am trying to see the last 5 mails in a single window that the rootuser has sent to a particular normal user.However,I am not able to do so.Is there any command that can display the last 5 mails in a single window sent to a particular user?
I use tomcat as my server platform in Ubuntu for a war file. I know in order to get real time information about how many user are logged in, we can count how many active sessions exist by a SessionCounter code. However, I have to permit HttpSessionListener in web.xml of tomcat. From other users' experiences, the configuration is complexed and has some errors.

In order to get users'ip, in jsp, use request.getremotehost() or request.getremoteaddress() by editing the jsp file. I wonder if there's some open source software to use for these two purposes.
