Okay, so do you recall that I own a Samsung SyncMaster S24B300? One of the reasons it had very bad capability is because Linux doesn't take kindly to "generic pnp monitors" apparently. My copy of that monitor did not come with driver software, and Samsung is still very finicky about giving drivers for anything other than Windows. Install the drivers for any ...

If you want to do a fresh install and are sure that you have backed up everything like you said, then you can do that. But you can try running sudo apt-get install linux-image-3.13.0-34-generic before doing that. This should install the kernel you were only able to boot in recovery mode (as I read it) and update the GRUB menu list to be fully functional ...

You could try making this the main video card in BIOS. the Acer monitor that is not detecting is connected to the video card through HDMI cable cord It might make it detectable and hopefully the other monitor connected to the other card will work too. There is no harm in giving it a shot because if nothing loads, then you can always just switch it back to ...

There is a known issue about this kind of HDMI audio detection issue when the laptop is booted without the charger. The power saving stuff sometimes make the detection not working. One easy way to verify this is to forcibly (harmless, don't worry) play a sound with command-line commands, assign the output to the HDMI port even if it's not in your sound ...

Check if your video card driver is installed correctly, by going to system settings, updates, additional drivers. Run Nvidia settings, when GUI opens check on the Nvidia gui how many monitors are detected, press on detect displays from within the gui and see if second display is detected. If that don't work out, check for driver or Linux software that can ...

I often hit this issue. To avoid crashing the Xfce theme (and getting the ugly buttons, etc.), I always first disable the external monitor output in Settings > Display and only then I physically unplug the cable. This workaround is a bit cumbersome, but since I started doing that I never encountered persistent issues with the Gtk theme in Xfce. It ...

HDMI output from devices such broadband set top boxes seem to output audio. I am not remotely convinced that computer graphics cards do this as well. Please check with the graphics card manufacturer to determine if yours is supposed to do that. Nothing is nearly as difficult to accomplish as the impossible.

Kinda stupid that I can't just comment, but whatever. It might be an overscan problem. There should be a 'just scan' option on your TV. If not, it might be an overscanning problem with Ubuntu, which can be set in xorg config settings. Does your mouse 'hit' the top of the screen? Or does it go past the top?

I've the same issue with a Lenovo ideacentre when using HDMI for video output. I've re-installed and 14.04 base install runs fine, applying updates kills X. I can still ssh in but not kill the Xorg process. Upgrading to 14.10 had the same problem. I've resorted to re-installing 14.04 and not applying updates. I suspect that the issue is related to xorg ...

I had the very same problem installing Lubuntu on a new media center PC I built recently with an embedded A4-5000. I had to download PulseAudio in order to change the default audio output (if I recall it was trying to do SPDIF) to HDMI out. Why it does not do this automatically I don't know. I also had the crackling noise you mentioned when I finally got my ...

Your problem may be with the NVidia drivers. Try using the open source Nouveau drivers. Go to the Additional Drivers page and select the "Open Source - Nouveau" option.
