HDMI is not working in Ubuntu 16.04
But this does not work for me. For example my firefox never liked to play audio thru hdmi while all other software did. Since i use pulse audio, it works like charm; check the end of this answer. I am using Lubuntu It might be different from your desktop, but automatic switching never occured by default.
I always had to direct the audio stream manually. In general you have at least two audio-outputs: One analoge audiojack and one digital hdmi, in general on different audio-cards. First i had to get an overview on the audiocards installed on my htpc ati motherboard with onboard graphics and onboard cpu :.
Now I needed to find out, which of these channels is used by my hdmi cable. Therefor I needed an audioplayer that allowed me to route the audio manually to test each of the above channels, one by one, until i found out, which of them belongs to my hdmi. With a GUI vlc and especially audacious come in handy. On CLI basis we could also use aplay, but i am not familiar with that. Now, after having found out, which channel belongs to my hdmi cable, it was card 0, device 3, i needed to create a file in my homefolder.
Also i needed to run 'alsamixer'. Since i installed PulseAudio the handling of the audio devices has become very easy. I would suggest you to install: sudo apt-get install gstreamer1.
I was having this exact same problem a few days ago. I tried everything but nothing worked. I spent almost an entire day trying to get this to work, but all to no avail.How To: Configure Nvidia card for Ubuntu Linux via HDMI HDTV
Yesterday, finally got tired of KDE because of some issues kWallet and kOrganizer were being difficult that just affected the usability of the DE.Ubuntu Forums Code of Conduct.

I booted into windows and it is working correctly. As mentioned in my AskUbuntu question I have attempted to reinstalled the Nvidia drivers to no avail. However in Additional Drivers, it specifically states that I am Code:.
Adv Reply. January 14th, 2. Re: Ubuntu Read "man apt-get". Note that "sudo apt-get upgrade" only upgrades existing packages, any may not do updates if related packages or dependencies change, so it may hold some things back. After doing "sudo apt-get update" it would be preferable to do "sudo apt-get dist-upgrade". That does a smarter upgrade to keep everything coordinated it does not change your Ubuntu version.
Normally with hybrid graphics there should be a panel to select Intel or Nvidia graphics although you might need to logout and back in or reboot when switching. Maybe something did not get removed or updated properly. I would try doing: Code:. January 15th, 3. Do lsmod and grep for DRM to see what video driver is loaded. If i is the default, you can switch to the Nvidia and logout or try to fix the i Bookmarks Bookmarks Digg del. The time now is PM.
I'm using this workstation at work with the TB18DC dock, where 2 external montiors are connected and work properly. But at home I do not have any dock and with the setup mentioned above the external monitor stopped working.
It did work some months ago. During the time it worked and now I have done normal ubuntu software updates where also the bios-firmware has been updated to 1. I booted from a live ubuntu usb stick and without external montior it worked normally but with external monitor I got the following error message:.
Go to Solution. I got it working thanks to this mans hint at askubuntu forum :. I recently installed the nvidia driver on my laptop which uses Ubuntu At first the external monitor worked perfectly, but after I switched from power saving mode sudo prime-select intel back to performance mode sudo prime-select nvidiathe second monitor was not detected anymore.
I discovered that prime-select writes a configuration file which causes the problem. It enables the nvidia-drm modeset option. You can simply undo the change made by prime-select by commenting out this option. It will not be reset, because prime-select only writes this file when it does not yet exists.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. There is a package called mate-optimus that I use to make sure that my nvidia card is active. The problem for me, is that the nvidia card is not active by default and I have to explicitly turn it on. Previously I was using nvidia-xrun to launch a full gnome session, but since I discovered the mate-optimus, I just use the little icon that it puts in the status bar to switch on the nvidia graphics which activates my hdmi.
I recently had this issue resolved on my laptop. I had manually downloaded drivers from the nvidia website but that wasn't the right way to do it. Ubuntu Ubuntu Community Ask! Sign up to join this community. The best answers are voted up and rise to the top.
Home Questions Tags Users Unanswered. Asked 5 months ago. Active 4 months ago. Viewed times. Can anyone help me? I have exactly same problem on Dell Inspiron What's also interesting is that the screen brightness adjustment does not work.
Have you managed to find a solution? It might be hardware. I have an Del Lx which also has an Optimus graphics system. Or inversely, I don't remember It's wired like that. From what I understand, the same problem exists under Windows. I've had a lot of problems using nvidia cards in Laptops. Even if they work, usually suspend and hibernate won't work reliable. Since the performance gain using a nvidia card in a Notebook is not that large, could you try to activate the intel graphic card and check if it works?

I contacted Nvidia but the said that they don't provide support shrug. I'm using Prime in order to switch between GPUs. Also read about bumblebee but I'm not sure about that.
Can some one guide me through this with reading material or telling me which are the steps in order to troubleshoot this issue.
Fix No Sound Through HDMI In External Monitor In Ubuntu Linux
What thing should I double check? What should I see in the outputs? Thanks in advanced Code:. Last edited: Aug 20, TechnoJunky Well-Known Member.
What desktop are you running? That's the default for Ubuntu. And unfortunately the only one that I find nearly impossible to work with in Settings options. I have the same video card, but I have a Dell and run Neon, which is based on I have Gnome installed on a VM, but I could not find these settings in it. I don't know if it's just me not being familar with Gnome or if Gnome just doesn't have this feature baked in.
I hope this helps or maybe someone who's more familiar with Gnome can use what I've provided to tell you where to find it.
