I appreciate this is an old question. You have no doubt long since resolved this issue. For anyone else who find this, I resolved this issue by heading to /etc/X11/xorg.conf and modifying to monitor HorizSync and VertRefresh values. I can't remember what they were but this is how the monitor section now appears. Section "Monitor" .... HorizSync ...

I was experiencing exactly the same problem with my Zenbook UX305UA...until today. This was a very annoying problem since it only has mini-HDMI output. The external monitor/tv/projector was only working if the laptop was turned on with the cable already plugged, but was freezing if connecting the cable once the system was running. Only hard power off could ...

I have a similar issue after updating 16.04 on a Thinkpad T440. My hdmi display is recognized (right definition and so), works for couple of seconds and is then disconnected. If I wait, ubuntu reconnects to the display, refresh the configuration, and again after few seconds it disconnects from the display. It was working perfectly before the update. uname: ...

Before anything, make sure your sound is not muted. ALSA and Pulse don't get together well. They are conflicting each other most of the times. Unless ALSA is specifically required by an app or hardware i recommend using only Pulse (it's newer and better). First, remove alsa completely by opening a Terminal window and typing: sudo apt-get remove ...

sudo apt-get install pavucontrol, can you try?

Alright, I think I've got something you can try. If you search for Multimedia Systems Select on the Dash. Open it and go to the Audio tab, where you can select the default audio Input and Output devices. This should be installed by default. If it isn't, you can always run sudo apt-get install gnome-media. If it is not shown in the Dash, run: gksudo gedit ...

I found the solution myself, so here the answer, if anyone else runs into it. It is an option I activated myself and forgot about it. If "Window Behavior" -> "Focus" -> "Focus stealing prevention" is set higher than "Medium" (actually when I can see a change in behavior all in all), then this issue of both menus opening and shortly closing after happens. ...

You can use pavucontrol (Pulseaudio volume control, install if necessary): Launch it from multimedia menu, go to the "output devices" tab, and click the green "define as alternative" button that is near HDMI soundcard. Look also "configuration" tab: you will find various profile such as HDMI .

So, personally I don't own this laptop, however I spent some time looking around. What I found was this: https://help.ubuntu.com/community/AsusZenbook#HDMI That help section basically says that if you want to use external displays, you'll need to leave them unplugged until you are booted up and logged in, which is what you've experienced. This seems to be ...

From the xrandr output it seems that no resolution is set for the TV. Try to set one of the resolutions listed under HDMI-1 in the xrandr output. For example: xrandr --output HDMI-1 --mode 1360x768

If the HDMI cable is not the issue, it could also be worth while to upgrade to a more recent video driver. There should be options for upgrading Your driver here: https://01.org/linuxgraphics/downloads/intel-graphics-installer-linux-1.4.0

Not much of help in your question, but I have the same issue. That "auto" in xrandr looks for a screen to set the resolution and so on at boot. I have a vague memory of running a "manual" xrandr command at startup to force the resolution in case the screen hasn't been detected,

First problem is bug in Metacity 1:3.18.3-1ubuntu3 and should be fixed by upgrading to 1:3.18.4-0ubuntu0.1 version. Unfortunately I don't have answer for your second problem...

I solved the issue with the same Lenovo ThinkCentre Q150 by switching to OpenELEC 7 Beta 3. link This version has been stable with only minor audio glitches. If you're heart is set on Kodibuntu, you could pull kernel and driver configuration settings from OpenELEC via SSH. There were other posts online I found which pointed to a kernel issue which caused ...

As far as you speakers go on your laptop, make sure you have not got a hardware mute button that is disabling them. Then check any software mute that is enabled. Finally if all that checks out, check BIOS settings to make sure there are no speaker settings in there somewhere that need to me adjusted. As far as display goes, try another cable - and acreen ...

Had a big D'oh! moment here. Might also help the eternally confused. No Linux was working for me. Found my pc had two hdmi outputs. One on the m'board and the other on the graphics card. Linux was correctly displaying from the graphics card to the TV but failed to set audio similarly. ROSA linux using KDE, found "HDMI2" on the audio output setup. It tested ...

I had a similar issue, it seems a little picky about what it will connect to. It wouldn't work with my monitor through a HDMI to DVI converter or in my TV through its second HDMI port, which is labled as a HDMI/DVI. It did however work in a different HDMI port (HDMI 1). So this is rather a long way of saying try a different port

OK, so after a couple of hours of digging through the Internet and learning shell scripting, I've mashed-up the script below, which brutally switches sound output device to what I want. //edit: I've also added test, if HDMI cable is connected #!/bin/bash while sleep 5s ; do SCR_SAVER_STATE=$(gnome-screensaver-command --query | grep -o "\w*active\w*") ...

I could solve the Output Problem, i can see the hole screen with the "underscan" Option, but this doesn't solve the reason for this Fault. The output of "xrandr" is stillgiving the worngphysicalMonitor size and i can't find the ...
