Debian Multimedia :: Keep Laptop Screen Lit When Plugging In HDMI Monitor
May 7, 2015
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.
I am running Debian 8.3, and I'm running Gnome 3.14.1.I have an external monitor plugged in with HDMI, and while Linux is loading both screens are on duplicate. Once the GUI kicks in, only the external screen works, so I have to enter my password blindly. Then, I open a terminal and run
I have a laptop and an external monitor connected via displayport. I can configure both displays via settings with correct resolution and arrangement. However, this configuration is not sticking, and every time I shut down the laptop or close the lid I will need to fight with black screens and more to bring the same configuration again. Basically, it seems that the monitor is "stealing" the primary role to the laptop's native screen (I have it configured as secondary, but also being primary the configuration gets messed).
After many trial & errors, this is the routine I have found to make things work every time I boot / awake the system:
1. Boot. Laptop's display shows the booting sequence. 2. When the login screen should appear, laptop's display goes black, monitor shows background. 3. If I press F9 to increase brightness, the brightness icon appears in the monitor, but it is stuck at the minimum. 4. The only way to leave this point is by pressing F7 (project screen) and then F9 again to increase brightness. Then the laptop's screen does light up.
This is when I'm lucky. Sometimes the configuration goes mad and I get mirrored displays and different resolutions, without touching the settings myself. Also, if I unplug the displayport I run the risk of getting stuck with a black screen in the laptop, without any way of recovering the GUI other than rebooting (Ctrl Alt F2 will still show the command line screen).
My system is Debian 8 testing up to date, running in a Lenovo T430 with Intel components. I'm not sure the monitor is relevant here, but in any case it is an Eizo CS240.
I have an Asus z9100 laptop with an Intel 855GM integrated graphics chip, which is running Karmic (the purpose of the laptop is to be a MythTV frontend so my understanding is that it needs to run 9.x in order to connect to the MythTV 0.22 backend - I have installed and configured this using the installable Mythbuntu package) and the laptop is subject to this bug which causes random freezes:

So, following advice for similar freezes I've seen, I have added the following options to my grub menu.lst on the kernel line:
nolapic nomodeset
and I have edited xorg.conf so that it makes use of the vesa driver instead of the Intel driver. This results in no freezes and if I wanted to watch Myth on the laptop screen I'd be squared away. However, the laptop has a damaged screen so the point was always to output the signal to an external monitor via its VGA out.
When I attach the external monitor and boot with the setup as described, the external monitor is never detected. But I noticed that if I remove the "nolapic nomodeset" from the kernel boot line, it is detected. However, signal is only output to it during the earliest part of boot (when the Ubuntu logo is in the center of the screen before the full-screen graphic with the animated progress line), after which the external monitor goes black and all the display output goes to the laptop screen. The external monitor power button is still lit up green as if it has been detected and is receiving signal, but it's just a black screen.
get the signal out to the external monitor after the initial part of the boot process, using the vesa driver? Here is the current state of my xorg.conf:
Code: Section "Device" Identifier "Configured Video Device" Driver "vesa" EndSection
I managed to install Jessie on my new Lenovo Ideapad 100 and have been trying to put the finishing touches on it. I downloaded FDPowermonitor and the icon showed up right away. Then after a few minutes it went away and hasn't shown back up.
I think I need to modify /etc/xdg/lxsession/LXDE/autostart to include @fdpowermon but I cannot figure out how to have the permission and use a editor I understand.
I just log into LXDE with root... but there has got to be a better way yes? But that didn't work anyway...
I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again. When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
I just installed a new GT240 w/HDMI and I have a new Vh232H monitor w/HDMII connected the video card and monitor via HDMI cable and started the computer.Nothing.The monitor is not getting a signal via HDMI.
the HDMI sound just doesn't work with PHILIPS LCD panel, but works fine with computer LCD monitor. I've tried following the numerous threads on those forums but in the end couldn't get any sound from TV. Sound plays fine if I plug it in windows 7 laptop.
Current system state:
BIOS settings for Azalia internal+external Natty with all updates Recompiled alsa 1.0.24 via alsa upgrade script pulseaudio
probe_masked hdmi device (there're also analog and S/PDIF devices on Relatek chip, but they are not loaded with current configuration)NVidia current (270.41.06)
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 noticed that Debian 8 has a significant bug related to detecting presence of display(s). Today, I woke my computer from sleep while the LCD monitor was unplugged from power (the monitor is connected via DVI) then I powered the monitor but nothing was displayed. Next, I connected another monitor via HDMI and both screens started working. However after disconnecting HDMI cable from the second monitor the first one with DVI stopped showing anything. The conclusion of this situation is that HDMI monitor must be connected all the time.
I thought that this is caused by graphics driver, but I experienced the problem on different machines, one with nvidia driver and DVI, and the second with default free driver and DisplayPort.
I just checked that this is related to KDE. After switching to console using ctrl+alt+f1 the screen turns on, but when I am going back via ctrl+alt+f7 the screen disappears.
I'm using i386 Jessie Debian, have an i7 Intel processor and Gtx 745 4gb NVidia GPU.
I am running with nomodeset due to blurring issue but issue occured without nomodeset too.
Problem:
When I start Debian with just a monitor in the HDMI slot it doesn't recognize the monitor and keeps the monitor at 1024x768.
When I start Debian with monitor in both DVI and HDMI slot it only activates the DVI monitor (with proper resolution). PC has no VGA I have no DP cable.

Which is my dvi monitor, no other screens detected. Is there any way to get the HDMI to run properly?
My monitor (Dell U2412M) has a VGA port, a display port and a DVI port. I can connect it to my laptop with VGA, no problem, but I'd rather use one of the other ports. I have a HDMI-to-DVI cable, so I tried that. That didn't work with my laptop, so I tested this HDMI-to-DVI cable with my raspberry pi, and that works perfectly. So, the problem is probably not the cable and not the DVI port on the monitor.
What happens when I plug the HDMI-to-DVI cable into my laptop is a bit weird. It's not a blank screen or anything, but part of the messages I see during boot. The last lines on the screen (the others relate to stuff that is probably not relevant for this issue), are these:
Code: Select all[ 10.823974] [drm] nouveau 0000:01:00.0: 0x7232: i2c wr fail: -6 [ 10.825122] [drm] nouveau 0000:01:00.0: 0x7244: i2c wr fail: -6 [ 11.487584] [drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call failed
I have had quite a bit of trouble with my GPU on this laptop, and as far as I can tell, the laptop does not use the nvidia card but rather has defaulted to the on board intel chip. Could these issues be connected?
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 recently installed Debian, using the amd64 Network Install .iso. I'm using XFCE4 as my desktop environment, and everything is working well... on my laptop's screen.
My desired setup is to have my laptop sitting on a well-ventilated shelf, closed, and to have an external monitor be my main monitor. I want this because I'm using my laptop as my "home" computer, so it never moves, and I don't like the keyboard/trackpad. My laptop has a VGA output, and I can get my desired setup on my Windows partition (not stating a preference ; just that the hardware CAN do what I want it to).
I've been working my way around the Internet for a few days, now, and I've got the commercial NVIDIA driver installed. If I run sudo nvidia-config --twinview I can get my external monitor to be part of the display, which is great, but it's part of a dual-screen monitor setup, which is not what I want at all, because (a) XFCE's multiple virtual desktops are good enough for me and (b) my graphics card is integrated, and I'm trying to squeeze every drop of performance out of my laptop that I can (1 gig of RAM; the less that my graphics card eats into it, the better). Plus, it'd be annoying to accidentally drop something on my laptop's screen, and then have to dig it out of the shelf in order to undo it. I'm not saying that I'm consistently clumsy, but I'd eventually end up doing it.
I have a Dell mini 10 netbook that I am trying to set up as a temporary HTPC. Using XP, I can send the video and audio over the HDMI connection, but when I attempt to do so from Ubuntu, there is not an option for a different monitor.
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.
Before I had Fedora, but only cuz all the devices were recognized by default, for a while now I wanted to switch over to Debian but as I came to relize my hardware for some reason is not working.
I'm running Debian Squeeze on a Dell Studio 1558 laptop, and I have my laptop set to suspend when my lid is closed. Resuming from suspend seems to work but the screen remains blank, forcing me to hard reboot every time. Upon reading this thread:

i want to connect my laptop to the lcd using hdmiI have nvidia video card 9200 gs and the driver is installedafter connecting both together nothing happens!do i have to change anything in the system or display settings?
I'm trying to get HDMI audio to play from my Dell XPX M1330 laptop through a HDMI cable to my Sony Bravia TV. This is a dual booted laptop. Booting into Windows 7 on the same laptop and streaming the desktop through HDMI cable to the TV shows up on the TV just fine, including sound through the TV's speakers.
However, when booting into my Debian laptop, with the HDMI cable already plugged in, I am able to play the videos, but no sound comes out of the TV's speakers. (plugging in the HDMI cable after logging into Gnome hangs up the entire system and I have to cold boot; setting that problem aside for now).
Since Windows 7 can figure this out, I consider this just something I don't have configured properly.
What do I need to do in order to enable sound to be piped through HDMI to the TV's speakers?
System details are shown below:
Pavucontrol Configuration tab dropdown indicating it is not sensing, or doesn't know about, the HDMI hardware:
cat /etc/debian_version shows 7.8
Output of aplay -l is:

I recently installed Ubuntu 10.10 on my Sony Vaio VPCEE2E1E. I've been able to avoid any major problems, however, my onboard sound doesn't work. I've tried plugging speakers into the laptop and this works perfectly. I'm rather confused as to why the onboard sound isn't working though.
Here's the output for lspci on my machine:

Mine is, ever since I installed the (wrong) opensource video driver for my Ubuntu 9.04 & Lenovo ThinkPad T41 (the one model, imho, they should never have let out the door!), uninstalled it by far-less-than-recommended means (ie, I used Synaptic and sudo apt-get remove and apt-get purge). End up is now my screen has a max resolution of 800 x 600, and Display panel insists that this laptop's screen is an "Unknown" Monitor.
Any tweaks to /etc/X11/xorg.conf (adding vertical refresh and horizontal sync rates for example) has resulted in its own weird behavior. On having my password accepted at login, there's a half-second of white that "rolls" over the screen horizontally. The next thing I see is a diagonal broken streak of white about 2 1/2" down from the top of the screen and 3 inches in from the right-hand side. The next thing I see is a buzzed,jagged rendition of my normal desktop. Nothing at all is clear, and the jags seem to redouble themselves the further one scans down on the screen. The only thing one can do in this situation, and I've done so enough times to know, is a hard reboot (power button for ten seconds or however long it takes).
And as I don't rate sh*t for a shilling on the Ubuntu forums, and as Google has been worse than useless every time I search for problems as detailled as these (it's like K-Mart: it has what you want until you go to look for it!), and as my one self-styled "Lunix-Geek" friend (now in the UK) has only briefly battled the xserver-xorg beasts, I'm coming here to see if anyone knows something else I could do besides bite the bullet, say goodby to my accumulated goodies, and reinstall Ubuntu.
The laptop is a samsung X30 and i spent days trying to install ubuntu 10.04 unsuccesfully as there was no clear picture on the screen, just a black and purple splodge. I then saw a post on these forums discussing the default resolution of ubuntu and how it is incompatible with some machines so via VGA cable i connected it to my TV and sure enough i could see what was going on and finished the installation process. I assumed that once ubuntu was fully installed i would be able to change the resolution using the monitor preferences but none of them worked. I am now faced with the problem that unless plugged into the TV i have no picture on my laptop, does anyone know why my laptop screen wont work with ubuntu and how
I am using DELL Latitude E5510 laptop with docking station. The problem I am facing is I am not able to switch screen b/w monitor and laptop screen, I tried with fn+F8 key. Actually I have installed open SuSE11.3(Linux) operating system.
I have an Okano 42" LCD TV, which I connect to my laptop via HDMI cable. Unfortunately, it doesn't fit the screen at the TV's resolution of 1920x1080, and there are about 40 pixels that run over the edge of each side on the TV, making the Ubuntu toolbars invisible.The standard NVIDIA control panel doesn't have any options for correcting this (in windows it had settings for adjusting the stretch/position of the screen), so I was wondering whether there are any common tools that ubuntu users can use to adjust the relative position and stretch of a screen?
BTW I think the cause of this is that my dodgy TV isn't correctly reporting its resolution to the laptop, and unlike most branded TVs, I don't have any system settings that can be adjusted to correct this (I know the panasonic counterpart can fix this in the system menu)..
I'm a new user and recently installed ubuntu on an old samsung laptop, during the installation process i couldnt see anything on the screen and came to the conclusion that ubuntu's default resolution was different to that of the laptop screen so i plugged it into my TV and sure enough it worked however i still only have a picture on the tv, ive tried all the resolutions available in the 'monitors' box but nothing, does anyone know how to fix this?
