Debian Hardware :: Unable To Use External Monitor Through Edock And Displayport

Feb 19, 2016

I'm using Jessie 8.3 on Dell laptop Latitude E7240.

Now when I plug the laptop in the Dell eDock docking station, external monitor connected through DisplayPort and it is detected (according to xrandr output).

BUT nothing shows on the monitor (it stays black) and I get errors repeating in the kernel log:

[ 71.064428] [drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting.

Ubuntu :: Setting Up X200 External Monitor (Displayport) Resolution?

Oct 12, 2010

I have finally decided to reach out for help because I've been messing around for 3 days with xorg.conf and I'm a beginner and not getting it right. What I want to do is to use only my external monitor (1920x1200) via DisplayPort when my computer is docked. And then my laptop display (1280x800) when undocked. I am using Ubuntu 10.04.

I have setup System->Preference->Monitor: Unchecked <same image in all monitors>, turned off laptop display, and set External monitor to 1920x1200. After doing this everything works when in Xwindows. The resolution is correct when I am docked, and when I am undocked it defaults to my laptop display.

The ONLY problem with using the System->Preferences->Monitor is that when I start up the computer when docked the external monitor goes to the incorrect (laptop screen) resolution at the initial login screen. After I login the resolution corrects itself but it's messy with reinitialization of the screen and my icons being all messed up. I think this happens because these settings only take effect after logging in.

I believe I have to edit the xorg.conf to get my setup working at the login screen. Can someone please tell me how to this.

Debian Hardware :: Black Screen Connecting Monitor To Laptop Via Displayport

Apr 19, 2015

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.

Debian Hardware :: External Monitor As The Main Monitor For A Laptop

Sep 22, 2010

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.

Ubuntu :: Unable To Connect An External Monitor To Laptop Running 10.04?

May 13, 2010

I've been unable to connect an external monitor to my laptop running 10.04, even though the resolution and framerate are right. The monitor says something like "unsupported video settings".

In other news, I put the live cd into another computer which relies on a monitor and after the very first screen with the two logos at the bottom, the monitor decides to go to sleep. I try with another monitor and it just seems to have to feed. This is the more important problem, but I wonder if there isn't some built-in problem with 10.04.

Debian Hardware :: External Monitor Not Detected

Oct 20, 2015

My system can't seem to detect the external monitor that I've plugged into my laptop using and HDMI cable. The monitor works when I'm booted into Windows so I know that it isn't a problem with the monitor or the cable.

When I run xrandr I get.

Debian Multimedia :: Cannot Set External Monitor To Higher Resolutions

Jul 8, 2011

I recently got a new external monitor for my laptop, and connected them by VGA. This is what 'xrandr' tells me:

Screen 0: minimum 320 x 200, current 1440 x 900, maximum 4096 x 4096
LVDS1 connected (normal left inverted right x axis y axis)
1280x800 60.0 +
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 510mm x 290mm
1920x1080 60.0 +
1600x1200 60.0
1680x1050 60.0
1280x1024 75.0 60.0
1440x900 75.0 59.9*
1280x960 60.0
1280x800 59.8
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1

However when I try to change to some of the higher resolutions, such as 1920x1080, all I get is a corrupted and flickering image. As indicated above, I am currently on 1440x900@59.9h,z but for some reason 1440x900@75hz doesn't work. The same seems to be true for 1280x1024. The three resolutions above that all cannot be selected properly. I tried setting the resolution to maximum in Windows XP and it worked, and my video games console can set it to 1080p, so I don't think there is anything wrong with the monitor. Is there anything I can do or is this some kind of bug or limitation of the graphics driver or something? The graphics chipset of the laptop is an Intel 945GM, which I believe should be capable of displaying 1920x1080. I am running debian unstable with what seems to be the most up to date version of xserver-xorg-video-intel.

Debian Multimedia :: NVidia Driver Not Working With External Monitor?

Mar 15, 2010

I have a Dell XPS M1330, which has a GeForce 8400M GS GPU. The binary (sigh) nVidia driver installed is version 190.53 (installed by sgfxi). This is working well: glxgears gives me about 2600 FPS and compiz is happy.An old Philips 170B is attached by VGA cable. I was looking to set up a method of switching resolution upon connecting to the monitor when working at the desk, since I don't like the 1280x800 resolution of the laptop.

nfortunately, I can't get any output on the external monitor. It does work under Ubuntu, which installed the 180 series binary driver. (Going to an earlier driver is an option, but I want to understand the problem.) Bottom line, I want to work under Debian.As far as I know, nVidia's proprietary driver doesn't support xrandr. At any rate, with he external 170B monitor attached and turned on, I get the following:$ xrandr -qScreen 0: minimum 320 x 175, current 1280 x 800, maximum 1280 x 800default connected 1280x800+0+0 0mm x 0mm

1280x80050.0*

960x540 53.0

Debian Hardware :: System Does Not Recognize External Monitor Via HDMI

Jun 30, 2014

Ok so I just installed Debian 7.5 on my laptop and encountered several problems.

First off was the problem with GNOME 3, GNOME 3 failed to load.

Second problem was that the system does not recognize an external monitor via hdmi. Via VGA I do not know do not have a cable to try it out.

Third problem was that my wireless was no recognized.

Dell Inspiron 5537 Laptop
wireless: Network controller: Atheros Communications Inc. AR9565 Wireless Network Adapter (rev 01)
Graphics card: VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) from the 4xxx series
System: 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u2 x86_64 GNU/Linux

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.

Debian Hardware :: Laptop Screen Goes Blank With External Monitor

Mar 28, 2016

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

Code: Select allsudo echo 950 > /sys/class/backlight/intel_backlight/brightness

and the laptop screen turns back on.

I'm wondering: Is there a way to streamline this so that it happens on boot, but after GNOME loads?Or: Is there a better method to solve this?

Hardware :: DisplayPort On Lenovo X301 Running Any Debian Variety?

Mar 31, 2011

I'm reloading my X301 Lenovo laptop with linux but need to make sure that whatever distro i choose will support displayport out. I'm currently running XP on it and DisplayPort -> HDMI (via converter) -> Sony 40" 1080 TV works great. Just Shift F7 and I'm off and running.

I tried Mint 10 and Debian 6.0.1 last night (via Live DVD) and while they both recognized the displayport, and I could set the resolution on a second monitor to 1920x1080, the output was scaled incorrectly and didn't show any user mouse movements etc... just the wallpaper basically.

Debian Configuration :: Copying Video Setup From Ubuntu - External Monitor

Oct 15, 2015

My laptop has a dual boot Debian + Ubuntu installation.

In particular I am using Debian 8.0 with stock kernel 3.16.0-4 (or equally 4.1.10 custom compiled, I tested it and it does not make any difference for the subject of this post).

Ubuntu is 14.10, with stock kernel 3.19.0-15.

In both installations I have nvidia nouveau drivers and intel integrated graphics drivers installed and loaded. This is the default for both installations.

In both installations I have xorg automatically configured (no xorg.conf file present in /etc/X11). In both systems the content of /usr/share/X11/xorg.conf.d is the same for what moitors are concerned (differences in mice and trackpad entries).

Unfortunately, the video configuration in Ubuntu 14.10 works out of the box. In particular I can plug in an external monitor/projector and it will fire-up the nvidia card (nouveau drivers) to power that monitor.

Debian 8.0 on the other hand does not even detect the external monitor.

I don't know where to start to solve the problems.

The hardware is as follows: the laptop (lenovo W530) features both an Intel integrated graphics card and an Nvidia K1000M. The VGA port is connected only to the Nvidia card (this is according to my online research, as I don't know how to check this).

Fedora :: External Monitor Won't Work - Both Monitor And Laptop Screen Black

Aug 7, 2011

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 have a Thinkpad E420, Fedora 15

Fedora Hardware :: External Monitor Not Detected - Dell Laptop - Monitor

Aug 17, 2011

My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.

My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.

Code:

How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.

Right now, the netbook has the panels, but the monitor has the desktop. I would like the panels and desktop on the monitor, even if that means not using the netbook screen. I have a screen shot below. I am running F13 with Gnome.

Edit: Never mind. I figured out how to disable the netbook screen using the function keys on the computer.

Selecting the different monitor size but always find my external monitor (ie TV) is to the left, right above or under the screen I see on my PC. Also I am unable to hear my PC through the TV. I should say this is a good quality flat screen and all I am unsure of are the correct settings to use my TV as an external monitor.

When I do presentation, I have to mirror the two monitors and both set to 1024*768, which is not perfect.

I remember that when I use RHEL 5 desktop edition, The system can automatically detect the external monitor and set it by itself ----- The laptop uses 1400*1050 and the external monitors such as projector uses 1024*768. But I haven't found such feature on FC11.

Fedora Hardware :: F15: External Monitor Blank?

May 26, 2011

Previous Fedora releases allowed me to connect to my external monitor via an HDMI-DVI cable to use as my main monitor from my laptop. However, after I did a fresh install of Fedora 15, I have this problem that when I login to gnome 3, both laptop screen and external monitor go blank. I cannot ctrl-alt-f2 to go to terminal. I end up having to ssh from another machine and reboot. Each time, the reboot doesn't even work since I have to go and kill Xorg before it starts to reboot.plymouth and gdm seem to be fine and show up the external monitor. It is only when I login to gnome3 that I get the blank screens.
