In PulseAudio, each sound card has a profile set associated with it. A profile set contains multiple profiles, and those are the profiles that you see when listing the cards (or when looking in the various PulseAudio GUIs). There is a default profile, which primarily contains things useful for analog sound output. There is also an extra-hdmi profile that ...

You should probably simply use kscreen instead, which should solve all your issues. It will remember the settings of a previously connected screen and will restore them, once you connect it again. If you still have such issues while still using kscreen, it should be worth a bug report. As Kubuntu 12.04 is quite old, you probably should have a look at this. ...

Option 1) Get a cheep hdmi to dvi cable, they are electrically the same (except no sound on dvi). Option 2) Use X11, to display windows from raspberry pi (running Raspbrian, or other X11 based Linux). Use ssh -X to connect to raspberry Pi. Option 3) Use VNC, to display whole screen, or a virtual screen. (Options 2 and 3, require a network connection ...

Finally I got it working for both screens. I didnt read the xorg log carefully enough. Noveau was being loaded along with nvidia and intel drivers. And it might be that the priority for noveau was higher. I did a complete uninstall of noveau and didnt install any driver apart form nvidia-340. That makes ubuntu graphics stable. sudo apt-get purge ...

The first thing you have to do is confirm whether or not the kernel really has a driver available for the display. Search online for the card in relation to linux to see if you can find out the name of the driver. If you have a kernel source tree available, you can also look for clues with there: find src/ -name Kconfig -print -exec grep 'some phrase' ...

I don't see anything wrong with parsing the output of ddccontrol. DDC is the right way to get the information you want. Unlike with VGA, where DDC was created, the HDMI connector was designed to include DDC from the start. They even went back and modified the DDC standard to add more features for HDMI, calling it E-DDC. On Linux, the userland tool for ...

So you've tried four OSs, including Windows, and it didn't work with any of them? Then it's very likely to be a hardware problem. The data in aplay -L doesn't preclude a hardware problem because that information comes from your audio chipset, not the actual HDMI port. If it's still under warranty, contact the manufacturer.

Put this in your /etc/asound.conf pcm.softvolPhonon { type softvol slave.pcm "default:CARD=0" control { name "HDMI" card 0 } min_dB -51.0 max_dB 0.0 resolution 100 hint { show on description "hdmi with extra Volume Control" } } You need to replace card 0 with the hdmi audio output in you system.

On television, go to Menu -> Input -> Edit name -> HDMI and set it to PC or DVI PC.

Based on the specifications at the link you provided, I don't believe this motherboard has CEC support. It's a fairly new standard, especially to the PC world.. You might try looking at http://www.pulse-eight.com/store/products/104-usb-hdmi-cec-adapter.aspx for an alternate solution. I haven't tried the device as of yet, but it is an intriguing looking ...

There is no "Best" solution, it is really up to the user which solution is "Best". Regardless of this, you have a few options that suit your needs... Ubuntu server This would suit your needs after a few apt-get install commands. you don't need to be an expert to use terminal commands :P (see tab auto-complete)" http://www.ubuntu.com/server/ OpenELEC ...

If it has a unique driver, you can blacklist the module. (Edit: Better Fedora link)

Your monitor provides information about itself using a digital standard called EDID. The kernel reads this information when detecting a display device and automatically configures its display to match as near as it can the display device's native resolution. LCD devices can, in truth, support only one resolution - their native resolution - and emulate all ...

I just managed to configure exactly this thanks to the instructions in the ArchLinux wiki : Set the one sink - HDMI - in pavucontrol/Configuration, and the other - analog output - you specify in default.pa : load-module module-alsa-sink device=hw:0,0 load-module module-combine-sink sink_name=combined set-default-sink combined Maybe you were missing the ...

Thanks to brm's comment and reading the xrandr man page, I figured out what the issue was. There were two problems: First, I'd always used xrandr's -s option, which specifies size, rather than the newer --mode option. This almost always works anyway, and in this case switching to xrandr --output HDMI-0 --mode 1920x1080 didn't fix things. However, it was ...

I'm no expert, but as far as I know, on board graphics are always disabled when you add a video card. I run three monitors, and I've set up dual monitors on several machines, but I have never once got the onboard video to work at all once addon cards are inserted. I'd love to be mistaken about that.

Yes, you can get raw video using different library like v4l2. For more help v4l2 help. I hope this helps you.

Try to install the latest intel hd graphics driver from here: Intel graphics Installer for linux 1.2.1

Finally I made it work using this line: xrandr --output HDMI1 --off xrandr --output HDMI1 --auto --scale-from 1366x768 Note that --auto is needed, though I don't know why.

Ok, after a sleepless night of googling and trying things out (like reinstalling unity and the x drivers), I decided to try out Intel's approach. Apparently they officially support linux and they have a graphics driver installer (link below). After downloading and installing everything started working again. I'm in Ubuntu heaven again. Enjoy! ...

Well obviously you can do it by running a program that reads audio from a capture device and writes it to the HDMI output (potentially through pulseaudio, so you can mix other sounds with it). I don't have any specific suggestion for you about what program to look for, sorry. I think it's unlikely that two different cards (the analog codec on the mobo, and ...

So apparently the settings and pipeline above are essentially good, and if you go to the ALSA forums they'll recommend something like the above, but a matching rate on your outputs is something that must be considered in addition. pcm.internal { type hw card 1 device 0 rate 48000 } pcm.hdmi_hw { type hw card 0 device 7 rate 48000 } My ...
