General :: Enable DVI Output On Laptop Docking Station - No Picture On Monitor
Aug 25, 2010
I have an HP EliteBook 8540p laptop with associated docking station. It is running Ubuntu 10.04. Until now I have been successfully running TwinView with the nvidia-195.36.24 drivers - using the built-in LCD screen and an external LCD monitor, connected via an analog VGA cable.I've changed the screen over to a larger resolution Philips LCD, and it works fine over VGA.
However the image is not as sharp as I'm used to with other monitors, so I'm trying to get it working over the DVI port on the laptop docking station.However I have been quite unsuccessful in getting a picture to appear on the external monitor - Xorg is able to read the EDID information from the monitor, and according to Xorg.0.log has absolutely no problems with finding a valid mode and choosing this monitor as "DFP-1", alongside "DFP-0" (laptop display). But no matter what I do I can't get a picture. Xorg.0.log has no errors.
I have unsuccessfully tried: various combinations of xorg.conf options to set "ConnectedMonitor", "CustomEDID" with a EDID .bin downloaded over VGA, etc.a colleague has the exact same laptop and monitor, and has it running fine. However using his xorg.conf still produces no picture.nvidia-settings - tried lots of things a different DVI-connected monitorIt's as if the DVI port is fully functional in every way but its output is somehow disabled. I've also tried other monitors, they don't work either, yet do with a VGA cable.
EDIT: I have checked the DVI cable anything else in terms of enabling a DVI port.

I use a Dell advanced port replicator at home and in the office. Each is connected to a second monitor. In neither place does the monitor actually receive a signal even though the monitor seems to be detected correctly in display settings. The function-F8 key does not have any visible effect.
Oh, almost forgot. At work once when I preparing to shut down the second monitor popped on for a few seconds though it was at the wrong resolution.

I have HP Compaq 6530b laptop running Debian Wheezy AMD64. I have a docking station with a monitor supporting 1680x1050 resolution and the laptop monitor with 1440x900. The video is integrated Intel mobile series 4.Both monitors are identified and working OK. When I use the laptop monitor standalone it runs at the native resolution. When connected to the docking station I can choose dual monitors with both using their native resolutions and the desktop spread on both of them (with the laptop monitor being primary and containing the taskbar and icons). If I choose to mirror the display it sets itself to a lower resolution of 1280x1024 that is supported by both monitors.
The problem is that I want to use one monitor at a time. If I close the lid of the laptop it turns off both monitors instead of using the docking station. When the lid is closed I want the bigger docking station monitor to be primary and working at native resolution and if I open the laptop or remove the laptop from the docking station to use the laptop monitor at it's native resolution.I had Debian Lenny I386 before and it was operating as expected but I made a clean install of Wheezy amd64 and I don't know how to configure it.I don't have xorg.conf file so I don't know where it takes the settings from.

I have been using Linux and Ubuntu only since the last two months on my (2006) Sony Vaio VGN A617S laptop which is going pretty well on Ubuntu 10.10. When installing Ubuntu audio did get installed alright, and the speakers on the laptop itself are working well even now with the right drivers (snd-hda-intel) for the Realtek ALC260 soundcard.
My problem is when laptop is docked to the A/V docking station (I have seen it referred as a port replicator as well - the model number is VGP-PRAV2), with its two external speakers. And these were not on when Ubuntu was being installed. What is interesting is the headphones jack on the laptop does work when the docking station does not.
I have been trying hard and have already tried quite a few things I saw to be related issues, like:
a) adjustments to some IEC958 in alsamixer
b) using a custom mod for the ALC260 card

Recently (in 2015) our Debian systems started not to recognize HDDs connected via an external docking station.
On my computer I run: (uname -a)
* Linux violin 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-3~deb8u1 (2015-04-24) x86_64 GNU/Linux
* If I connect to a flashdrive to the USB2 port, it is recognized as sd* (messages are also written to dmesg/syslog)
* If I connect the USB3 connector of the external docking station with an 1TB WD SATA docked, to this USB2 port (the external docking station has its own power supply, so I do not expect to have a problem with the current, the drive spins up and is spinning), there is nothing in the dmesg/syslog, and no new items under /dev/sd* or lsusb or similar tools.
* If I connect the same external docking station with the same disk via eSATA on a different computer it is recognized. That computer runs the same debian. If I connect through its USB2 port it does not work either.
* I also tried another docking station and USB cable.

While using Debian Jessie with Gnome 3 and Nautilus file manager, my Startech HDD docking station will not auto mount and can only be mounted using commandline while in root. Previous GNU/Linux distros, such as Ubuntu 14.04, this device auto mounted without issue. All other devices, such as USB HDD, and USB pen drives, auto mount without any problems.
"Initailize Startech device with a 120GB 2.5" SATA HDD Fujitsu drive"
udev creates two block devices
Code: Select all begins with:
brw------- 1 root root 8, 64 Aug 6 10:11 /dev/sde
brw------- 1 root root 8, 65 Aug 6 10:12 /dev/sde1
changes to:
brw------- 1 root root 8, 64 Aug 6 10:11 /dev/sde
brw-rw---- 1 root disk 8, 65 Aug 6 10:12 /dev/sde1
dmesg produces the following results:
Code: Select all[ 179.127724] scsi 6:0:0:0: Direct-Access FUJITSU MHW2120BJ G2 0000 PQ: 0 ANSI: 2 CCS

[Code] ....
Between the thirty second and the fifteen second wait, the block device "/dev/sde1" receives the "disk" group and read/write attributes, however, the drive is still not auto mounted and can only be manually mounted via root. The block device "/dev/sde" remains with the "root" group and read/write attributes are accessible for "root" user only.
How to correct this issue to allow auto mounting?

I recently upgraded to Natty (11.04). Looks great but: I can't use it when my laptop (dell latitude E6410) is plugged in my dell docking station. It seems like the attached monitor (DVI) does not get signal input and hence turn to sleep mode.I can say that Ubuntu is still running fine when I unplug it from the docking station.I am using the NVidia driver 270.41.06 (installed as a third party driver by the install process).I can successfully connect and configure an external monitor thru the VGA port.

I want to "build" a new backup solution for my home LAN. I have 3 openSUSE machines at various versions and 1 File Server with openSUSE 11.4.My plan is to plug a eSATA or USB3 docking station on the file server and then take backups from the clients either via rsync or Amanda.Since the backup will not be a daily activity, I would like to have the option to run the backup during night, and automatically, BUT, without any action from my part. So, I would like to attach a large external HDD on the machine and then:Power on the docking station/HDD.Perform the backup from the Amanda Server or rsync scripts.Power off the docking station/HDD.Do you know any docking station that has a "linux" power management?If not, how do I power up/power down from console an eSATA or USB HDD?

I have a Dell E6250 for work and a docking station with dual DVI going to two Dell 1908FPc. It looks like I can only configure two monitors and after I enable dual head support, X11 crashes. I can use Function+F8 to switch between them, but I cannot figure out how to get both monitors on at once. i.e. I close the lid of the laptop to use the dual monitors.

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 have Dell Vostro 3300 with Intel HD integrated graphic card and Samsung SyncMaster 2343BW external monitor.
This is the output of xrandr:
It runs on 2048x1152 full resolution, however, the picture on the monitor is blurry, it vibrates and looks like old TV with interlacing.
I tried to disable output to LVDS screen on laptop using xrandr but it doesn't help/
Previously I had HP laptop with integrated Intel and OpenSuse 11.0 and the external screen worked normally.

I have an old Compaq Pro desktop with Ubuntu 8.04 installed. been using it without a major problem until four days ago. When I attempted to boot all I got was a screen with green vertical lines at the top and horizontal yellow, red, and orange lines below that. Since I recently had downloaded a new kernal I tried to use another kernal but that got the same result. I tried to boot with a live cd and finally got it to boot in low graphics mode. I have also tried to boot into the safe mode and tried the recovery option.got the following warning:xserver-xorg postinst warning: overwriteing possibly customized configuration file; backup in /etc/X11/xorg.conf .20100323151611I have no idea what that means or what I should do. Can anyone point me in the right direction? I would really hate to wait the 30 some odd days for 10.04 to come out.

I have a laptop with a broken lid, it is beyond repair so I want to make something out of it. I have unscrewed some screws and I have managed to swivel the screen around, so it looks like a tablet (screen over keyboard - not glued - yet!)I want to change this laptop thing into a News/Calendar/Weather station, that turns on automatically (I can set this in the BIOS) and start running. As I just mentioned, I want it to show News, My Calendar from Google Calendar, Weather and maybe my email. Heres a mock up of what I am thinking of -
Do you guys know any programs that would allow me to create this? The computer is running Windows XP and can be changed to Ubuntu if needed. Windows 7 is a no no (wireless driver is not compatible).

Im running ubuntu 10.04 on a Acer TravelMate 5520, ATI Xpress 1250. The Sony 40" TV is connected to the laptop with a VGA plug, but with 10.04 im finding the output picture is wobbly, distorted regardless of resolution.
It does work fine on ubuntu 9.04, picture perfect. Ive booted into both and checked the resolution and their identical.

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

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.

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.

Is there any way, how to make connecting monitor to my laptop as easy as it is e.g. in Windows? Just plug-n-play? I've just installed last version of Ubuntu and then connect monitor. After connecting monitor nothing happened (my laptop LCD doesn't get blinked and it doesn't try to use the monitor as a second one). So I went to Monitors configuration, where I saw "Mirror screens". I've unchecked "Same image in all monitors" and applied, also nothing happened. The monitor is still just black. Is there any application which would make this stuff easier for me? I have HP ProBook 5320m with some Intel HD graphic card inside and 21.5" LG W2240T-PN monitor.

I have an HP Pavilion dv9000 which I would like to use completely with any Linux OS. I have tried to install Linux Ubuntu 10.04.1 but it appears that it doesn't recognize the external monitor and ends the installation. I have a clean hard drive that I could install but I do not know which of the two drives I should replace. I can only get into windows in safe mode and I would think this may have something to do with the problem, don't no.
