Ubuntu :: HDMI To Multiple (Really Only 3) TVs
Aug 4, 2010
I was looking for a solution to watch HDTV quality videos on multiple tv's. I have a cable run and cat5 run to each room and wanted a way to watch hidef movies in each room preferably synced. After much searching I'm coming to the conclusion that this will be hard and expensive no matter which route I want to go. I'm thinking my best route is to build a media converter and pipe that to each room.
I found a couple of HDMI input cards [URL] and [URL] that work in linux. Great with one of those I can get it to a computer signal and even get it on standard coax using a VGA2RCA converter and 1/8 inch to rca for audio hooked up to an old vcr set to channel 3 or 4. And for TV's that support hidef I can hook up computers at each to receive the video over gig ethernet.
So the question becomes what is a good app for sending and what is a good app for receiving. Is gig ethernet fast enough for 1080i? what about 1080p? Comcast has multiple hdtv channels over their coax; so how is it so hard to even encode one channel to an hdtv signal to watch on tv. Is there a way to encode the video to hdtv over the coax like comcast? So I can use the tv itself to watch the hdtv broadcast from my computer over the coax?

I realise this is an issue that has been covered a lot, one way or another, but at least from what I've been able to find, most of the discussion centres around getting HDMI audio to work. However, I have problems even getting the video to work from my laptop's HDMI output.
I have an HP dv6z-se, with an ATI Mobility Radeon HD 6550 (1 Gb) video card and using F14/KDE. My problem is that when I go to System Settings/Display/Monitor, Fedora doesn't actually seem to realise my computer even has an HDMI output and only displays options for VGA and my integrated screen.
When I plug it into my LCD screen, sometimes I get a 'No Signal' message and sometimes I get garbled static and a message about unrecognised input and the frequency it's coming at.
I read elsewhere in the forum that someone was able to get video working by editing their xorg.conf file, so I went in and tried to see if I could replicate that, but none of the files in my xorg.conf.d folder had anything related to video outputs (as far as I can tell at this point).

We are working on a project to create a display wall of 8 monitors arranged as 2 high by 4 wide. Each monitor is connected to a single machine and all machines are networked with a master machine with its own, seperate monitor.
Our goal is to get the 8 machines to share a single desktop, with the master machine acting as the server. We have looked at using Xinerama or NMM, but we are unsure about how to get started configuring the multi-machine, multi-head display.

I often use the rpl command to make changes to multiple html files at once. For example:
rpl -R '<br />' '<br /><br />' mydirectory However, I haven't been able to figure out how to change multiple lines. For example, let's say I want to change all occurrences of :
<br />
<br />
to:
<br />
I've tried
rpl -R '<br />
<br />' '<br />' mydirectory
but that didn't work. how to do this with rpl or some other way?

I'm trying to connect one computer to two others in an ad-hoc infrastructure.
[computer 1] ---- [computer 2] ---- [computer 3]
computer 2 is running Linux and has a single NIC wlan0. I want to it to connect to both computer 1 and computer 3 so each computer can talk to the other. No switch is available so it needs to be an ad-hoc setup.

I am to rename all the files within a directory (which contains multiple subdirectories) recursively without invalid characters.
I tried the coding posted above.
find . -type f -printf '%p
' | while read file; do
oldfile=$(basename "$file")
newfile=$(echo "$oldfile" | sed 's/[^A-Za-z0-9_.]/_/g')
if [ ! "$newfile" == "$oldfile" ]; then
echo mv "$file" "${file%$oldfile}$newfile"
code....
but I get an error on both of them stating "find: bad option -printf find: [-H | -L] path-list predicate-list"

I'm starting to have A LOT of opened windows in my machine. Sometimes within a project, I have e-mail/task management/personal e-mail/twitter, and a lot of different opened applications/terminals in my Linux workstation.Sometimes it would be interesting to have different workspaces to projects instead of this configuration I have nowadays that are classes of work (bad name, I know, but I think you got the idea).I'm starting to think about using two monitors: one with Corporate Management, Work and Personal. The second monitor is only the development state: each workspace here is about a project being worked on instead of groups of works like before. A workspace may be implementing different classes for example.
My question is: I just want to change to a second monitor using the mouse. I want to still be able to change workspaces in the same monitor using keyboard shortcuts. The keyboard shortcuts wouldn't change monitors, just worskpaces on the same monitor. All the tutorials I read (like this one) only tells how to use multiple monitors but doesn't answer my question about keyboard shortcuts.Does Linux (Ubuntu 10.04 Lucid Lynx or Debian 5.0.5 Lenny) support this envisioned setup (Different workspaces in a way that keyboard workspace switching only works in the current monitor) ? If so, how?I haven't tested this setup, that's why I'm asking. In this question the user says it works exactly how I want it to behave, can someone else confirm it?

I have an old pentium 3 computer that has ~7 NICs installed. These NICs are attached to modems and other networking equipment. According to the linux ping page on computerhope.com, it seems that one could send a ping from a certain specified NIC. How would one go about this?

I'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails
* Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.

I have a CentOS 5.3 box with three network interfaces in it. Each interface is attached to a separate VLAN and I want traffic to stay on each network segment.What I can�t figure out is why I cannot get each interface to have its own gateway and everything gets sent through the default gateway.The basically takes my possible 3Gb total bandwidth and throws it down a single 1Gb pipe.Then on top of that, if I take down the interface (ifdown) that has the current default gateway,I loose contact to the other two interfaces.When I look at the routes, each one of the interfaces shows the gw as 0.0.0.0 and defers to the default route. So I delete the route and try to add a new route with:
[root@testsan ~]# ip route add 10.1.15.0/24 via 10.1.15.1 dev eth2
but end up with the error:
RTNETLINK answers: Network is unreachable
[root@testsan sysconfig]# cat network
NETWORKING=yes
NETWORKING_IPV6=no[code].....

Can someone provide me with the exact instructions I need to backtrace pulseaudio? I have a bug that a developer is asking me to do a backtrace and the instructions on the ubuntu site aren't very good. I tried exactly what it said and my problem is that it says to "run the program under gdb by doing
gdb pulseaudio 2>&1 | tee ~/gdb-pulseaudio.txt
unfortunately pulseaudio isn't actually starting when I do this (I kill the program before I do this command, I also add the appropriate text file so pulse doesn't auto restart). Not sure what's going on but I'd appreciate any help as I can't get sound out of HDMI (I get it but it dies out fast).

I have a on-board video card (ATI Radeon HD4200) that capable to output HDMI as well as VGA.I connected both into my TV (which also have VGA input as well as HDMI). Here is the weird thing:IF I reboot my computer (9.10 64bit) with my TV set to display HDMI, then after I login at my workspace, my HDMI display got cut off at the edge! BUT my VGA display correctly when I switch to it on my TV.HOWEVER, IF I reboot my computer with my TV set to display VGA, then after I login at my workspace, my VGA display correctly AND my HDMI display correctly.What's the deal here? I am trying to use only HDMI connection and eliminate the VGA as well as the analog audio wire (which the HDMI audio is another big problem but for another post).

I have an HP 8510w laptop and I run ubuntu 10.04 out of an external harddrive.
I have no problem getting video over hdmi using the latest proprietary nvidia drivers however I cannot get sound through the HDMI cable.
I have read around without being able to find a solution.
Running "aplay -l" shows only my intel sound card and also there is no hdmi sound interface in the sound preferences (Only the normal output interface).
I am using the latest proprietary nvidia drivers (Believe it to be 1.95) and the graphics card is a Quadro FX 570.
how I can get sound out to work via the hdmi cable?

I recently put together a small computer on which I'm running Ubuntu 10.04. The plan here was to test the motherboard out for use in a HTPC running linux, and using smplayer and vdpau (not exactly sure if that's the way to say it), I'm running video just fine out of my HDMI cable, but I'm not having any luck getting any audio.
My motherboard is one of those Zotac Ion Itx G-E with an NVidia Geforece 9400 thingamajig. Customer reviews on New Egg said it handled Linux and Mythbuntu well, and that was my reason for making this purchase. When I recieved my motherboard, I loaded Ubuntu as the instructions said I should, and then I attempted to load the disc with the drivers and that failed. Apparently, the disc was designed to run in Windows. I downloaded drivers from the Zotac website which were supposedly designed for linux, however I haven't had any luck installing these. The terminal keeps saying I need the installer.

I am still struggling with getting my HDMI working under Ubuntu lucid. I added the ricotz/unstable repositories to get the latest version of ALSA (1.0.23):
Code:
sudo add-apt-repository ppa:ricotz/unstable
sudo apt-get update
sudo apt-get upgrade
All 1.0.23 related packages were installed (Alsa base, alsa utils, libasound).If I check the ALSA version in /proc/asound:
Code:
bas@ubuntu-lt:~$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21. Result, still no HDMI ports available when I type aplay -l:

I have recently installed Ubuntu 10.10. Everything is working fine except I have no sound. When I use the command 'aplay -D hw:0,0 somefile.wav', I can get sound through headphones attached to the headphone jack. But I can't get any sound through the speakers. This is a dual boot desktop and the sound works fine under Windows, so no problems with hardware. The PC monitor is connected through a hdmi cable and I would need sound through the speakers. The output of alsa-info.sh is at

I am big fan of Ubuntu and presently doing a lot of research on switching over to Ubuntu from Windows environment.
First things first
My desktop basic hardware specs
Motherboard: GIGABYTE MA790XT-UD4P
CPU: AMD PHENON 545
GPU: NVIDIA GT240 (1GB)
RAM: 4GB
POWER: 650W
HDD: 1TB
I am using Win 7 64bit and installed Ubuntu 10.10 64bit Ubuntu installation went smooth and it got updated...
Everything is fine except couple of things
1. No audio output from HDMI.
2. No Multitasking.
I will elaborate the above issues
1. My comp display is my LCD TV which is connected by HDMI cable, usually I get sound from TV speakers when I use Win 7, however in Ubuntu there is option to select the sound output by HDMI but even though after selecting nothing happens...
2. Whenever I am to listen to music in Ubuntu and if I am doing some other work like copying files or opening multiple files or burning DVD's, music gets stuck or it plays pause by pause...so multitasking problems...

I have an ECS gf7100pvt-m3 that has the Nvidia MCP73 chipset that supports HDMI out. Unfortunately the MB only has a DVI connector which from what I have read is supposed to cross wire the audio to the correct pins on the HDMI (have a ticket in with ECS to see if like ATI there is a special adapter).
I have tried every thing but only Analog audio is working.
I've tried listed on these links to no avail:
[url]

The only error is the at the Aumix isn't touching....I can select HDMI or IEC958 1 etc etc and the audio mixer shows full blue as if it should be working but I can't get VLC or MythTV to output sound.
