Ubuntu :: HDMI Signal Is Lost When Laptop Lid Is Closed
Nov 25, 2010
I am running Ubuntu 10.04 on an Acer Aspire 6930 with an nVidia GeForce 9300m GS hooked up to my LG TV via HDMI.I have used the nVidia configuration tool to set the TV as a clone of my desktop and all appears to be working fine except for one thing.When I close my laptop lid, the TV also blanks.I know I could turn off my laptop monitor from within the nVidia config tool, but that is not what I want to do as I still use it; and besides, it's inconvenient to have to do it all the time.

When I change the "When laptop lid is closed" option in Gnome Power Manager to either "Blank Screen" or "Do Nothing" (by manually using gconf-editor), the screen itself doesn't turn off when the lid is closed. Obviously not a huge deal, as I could just change the "idle before sleep" on certain occasions, but I liked that setting it to "Do Nothing" previously would actually turn off the screen when the lid was closed.

I am running 11.04 on a new Gateway with 8 gigs of ram. It is a solo installation. The monitor is connected via an HDMI cable. Everything was great (installation running smoothly for over a month) until last night. I just installed a netgear router and was setting it up with the system to try to get Stanza on my IPAD to connect to Calibre. Anyway, i suffered a severe freeze up warranting a hard boot. I could see the drive working, ancillary drives lit up, keyboard lit up so I know the system is working. The monitor did not come on, It shows a yellow light indication no signal. It is a 28" Hansspree. I tested the monitor by hooking it to a laptop. The monitor is fine. I cannot see anything on the screen so I can't boot to repair mode or use a CD. There is no signal.

I have Lenovo SL500 with ubuntu 10.10. Also i have installed latest GeForce 9300M GS drivers from NVIDIA site. NVTV is also installed. When i want to connect to LG 32LE4500 trough HDMI i get no singnal message. I tried to configure with nvidia-settings but no positive results. Also i have tried with bigger SAMSUNG screen but no results... am i doing something wrong? Or, is this problem with NVIDIA (or ubuntu) HDMI support. If it is, where can i find information when will be bigger support for HDMI with NVIDIA and ubuntu?

I'm forwarding an application (HandBrakegui) over an ssh tunnel using X11 forwarding as follows
ssh -C -p PORTNUM user@host -X ghb
This all works fine and X11 loads and handbrake's X11 output to my local mac.The server is Ubuntu 10.4 and the client is Mac OS X.Is it possible for the X11 HandBrake Gui session to be kept alive once the SSH tunnel or the X11 window on the client (mac) has been closed? As I'm adding files to HandBrakes queue I want the programme to finish encoding them even if I turn off the client computer as the server is always on.

If I close my laptop lid for more than a few seconds, my screen will become completely unresponsive, aside from the cursor. Any idea what could be causing this?

I'm running CentOS 5.3. I have the laptop configured to suspend when the lid is closed. But it won't suspend when the lid is closed. Add if I try to suspend from the toolbar, it won't suspend.

I like to play videos from my laptop on my tv in my bedroom using an hdmi cable. I used it in windows all the time. I have gotten Ubuntu configured to play the video and sound but I cant figure out a way to keep playing when I close the lid. Every time I do that it goes black. Also when I re-open it the laptop display is blank as well and will not come back on.
Under the power option when lid closed all it offers is
Blank screen
Suspend
Hibernate
shut down
In Windows I had a "do nothing"
Anyway to do this in Ubuntu?

I just installed Ubuntu 9.10 CLI with Openbox as the WM on my Dell laptop. I installed gnome-power-manager because I like to suspend my laptop when the lid is closed. When the close the lid and reopen it, the screen is black and the computer never suspends. This happens regardless of whether or not gnome-power-manger is running is the background.

Did an upgrade from 10.04 to 10.10 and it was very smooth. One minor issue is now when I close my laptops lid (Sony Vaio) it does not sleep it just shuts downs. Same with habernate. It just shuts down all together. Then when I boot I get a brief error message to fast to read and the old 10.04 password screen rather than the new 10.10. This does not happen when I just shut down from inside Gnome and this never happened in 10.04. I am using generic video settings and all else works a charm.

I have Ubuntu 10.10 installed on a laptop. The laptop has an external 19" screen connected to it through the VGA port. I am not using the laptop screen (because it is small and flickers constantly) but only the external screen. When I shut the laptop lid the external screen blanks. There is no option in the power management dialog and the option "Activate screensaver when idle..." in the screensaver dialog is unchecked (which I would like to re-enable to blank screen when idle for x minutes). How can I get Ubuntu to leave my external screen on when the laptop lid is closed?

I have a Dell Studio 1737 running Ubuntu 10.04 LTS.My WiFi was working fine a few days ago until I tried to boot into another mode that allows me to boot into my other Ubuntu 10.04 or Windows Vista.I booted into that Ubuntu, which I thought had been overwritten when I was having problems and installed the one I am currently using.I shut down since it didn't have anything of any use to me at the moment, and I booted back into this current Ubuntu.Now, whenever I shut my laptop screen and open it back up to login, the WiFi is disconnected.(I was also having this problem on the Ubuntu that I booted into earlier, but that WiFi did this from the start on that one.)

My IBM Thinkpad T42 laptop fan is constantly running when the laptop is open.I only use AC power.Fan turns off when laptop is closed, which I did by selecting Suspend in Power Management.
cpufreqd and cpufrequtils are installed. cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor' is 'ondemand'
Constant fan was not a problem in XP Pro; I just installed Debian one month ago.

I don't know if it sounds weird but I've been trying for weeks with no result. I want to plug my external monitor through my laptop's vga plug, close the lid and work on my monitor instead of the laptop's monitor. I looked through the gnome power management settings and when the laptop lid is closed it can only suspend, blank screen, hibernate or shutdown. I can plug my monitor and I have clone displays and it works fine but I can' find a way to shutdown the laptop screen without shutting down the vga outlet. Its a brand new Acer aspire 5734Z with a 15,6 inches screen (wich is why I want to plug in my 19 inches monitor and work on bigger screen)

I have a Lenovo T440p.I am on Debian Jessie. I use KDE as my desktop environment. My Wifi adapter is Intel® Dual Band Wireless-N 7260. I have configured my laptop not to suspend itself when the lid is down. I can verify that the laptop still runs when the lid is down, because I can hear the music if it is already playing. However the Wifi always disconnects when the lid is down. If I am downloading a file, it always gets interrupted.

The old Nvidia GT220 recently died in my HTPC and I replaced it with a new GT430. Sound over HDMI worked beautifully with the old card (after much trial & error,) but has now stopped working with the new card.Forgot to mention that everything appears to be unmuted in alsamixer. When I run "aplay -D plughw:1,3 /usr/share/ sounds/alsa/Front_Center.wav" I get no sound. I do however get sound from the headphone jack when I do the same command for the onboard sound card (0,0)

I recently installed Ubuntu 11.04 on my HP Pavilion dv4-1040ee laptop which was shipped with nVidia GeForce 9200M GS graphics card, the only problem that I'm currently facing is that the computer was not able to detect my screen by using the HDMI port. So, I thought that may be it was a driver's issue so I installed the latest nVidia dirvers by using the command
Code:
sudo apt-get install nvidia-current
When I restarted the computer nVidia's logo appeared during booting and nVidia X Server

I have a weird problem, i have an LG LCD screen that i connect to my laptop via HDMI through nVidia. I was watching full length movies and everything worked perfectly. So, i got myself a new, slightly bigger LG LCD, and now, when I play a movie, about 20-60 minutes into the movie, my machine just turns off. doesnt even shutdown properly, just turns itself off, as if the power ran out (which it didnt..)
I thought maybe i had too many things installed, or mabe i should wait for a new version.. so i waited till i reinstalled a fresh 10.4 on a new partition, played a movie, and again, the machine just suddenly turned itself off.
i tried looking in the system log viewer, but between shutdown and startup, i see nothing special (besides ALOT of "rt_ioctl_giwscan. 1(1) BSS returned, data->length = 105")..
i tried running 64bit & 32bit and it has the same error.

Where the script is for Gnome 3. When I plug the HDMI cable, the desktop expands to include both, but disables the backlight on the laptop monitor. I have to restart gdm3 or the laptop for the brightness control to bring it back up. First, why would it turn brightness to 0, and how do I change the default of that so it stops. I plug and unplug the HDMI regualarly while I wait for a new desktop and the laptop has to pull double duty.
I just switched from Ubuntu 14.10. It never blacked out a screen on plug in or removing. That means that there must be some way to do it, however, it used Unity and this is Gnome 3.
I installed KDE. It works as well. I will use it for now, but would like to get Gnome 3 to work. My default is gdm but I think I saw I can switch it to kdm.

Off and on for some time now I've been using a Toshiba x205-s9359 laptop with (11.4/KDE4.6) during the day as a general purpose laptop using the onboard LCD and in the evenings to run XBMC to play movies on a TV using an HDMI cable (no cable TV on our little island & Satellite TV is poor in the rainy season).
The video card is an NVidia GeForce 8700M GT with NVidia's proprietary driver v. 275.09.07 (installed the "hard way").
Audio info:
Code:
~> aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC268 Analog [ALC268 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
[Code]....
Now the Audio/Video both go to the TV via HDMI if it's connected prior to boot, if not the laptop works normally.
If you try this with XBMC don't forget to go to set the XBMC settings to "HDMI" as needed.
