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.

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.

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 been using Ubuntu for a while now on my netbook, however I have an older HP dv5 laptop that hasn't been used in a couple of years that I would like to format and install a linux distro on. Problem is that it has a very broken LCD screen and I had been previously using an external monitor with it. I had tried to install Ubuntu 9.04 on it at one point but could not progress very far into the installation due to the external monitor. I had also tried using the non-graphical installer but had little success with it as well.
I had thought of removing the HDD from the laptop and putting it into another of my laptops and installing it that way, but the specs are different between the two laptops and I figured that it would not work properly once the HDD was switched back to the older laptop. Is there any way to use an external monitor to install a newer version of Ubuntu? or perhaps is there another distro that is easily installed using an external monitor? My plan is to eventually remove the broken screen all together and only have the external monitor connected, the broken screen is a bit unsightly.

I am looking for a way to switch quickly and easily between my Laptop Display and my External Monitor, in Windows I had it configured so that when I plugged my Monitor in it would switch to that and when I removed it it would switch back to Laptop Display. From what I have tried it looks like this isn't possible with Linux, but I would like to get to the stage when I can click an icon to switch (or 1 to go to External and 1 to go to Laptop) My Laptop has an ATI Mobility Radeon HD 4500 Series Graphics Card and I have so far noticed the following issues.
1. If I use the Gnome Monitors instead of ATI Catalist Control Centre it seams to cause some strange issues include confusing Linux on what the max screen res supported by my External Monitor is.
2. When I try and enable/Disable either Display or change Resolution, I am told that I have to reboot before the changes take affect.

I have slackware 13.1 installed on my laptop and use kde.I just bought a new external monitor 1680 X 1050. The laptop's monitor is 1280 X 800. From KDE i configured laptop's screen to be inactive and the external monitor at resolution 1680 X 1050. When i boot and enter KDE both monitors are activated, ican't understand their resolution. Then, just when i enter system configuration-monitor-monitor configuration the laptop's monitor automaticly turns off. Then i configure the external to 1680 X 1050 resolution. This happens every time i have to enter slackware. How to setup my xorg.conf file. You can see it below:

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 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?

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.

I'd like to solve a little problem that I have connecting my notebook with an external VGA monitor.Everything seems to work fine, but when I close the laptop monitor, also the external monitor shuts down.I've tried to find different energy-saving setting for laptop display and external monitor. with no luck...My video card is an ATI Radeon Xpress 200M. On the ATI website there is no catalist control center for linux. (It would be very useful). So, for now, I can only use the display options on the panel.

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 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:
[URL]
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

im having problems connecting mybook 2 with my laptop. Everything was ok and running perfectly and there was no changes in my laptop or upgrades and it stop working. I was not able to see the computers in my network then I fixed it I can see them but when I try to browse the files the OS tells me that is unable to mount location and failed to retrieve share list from server. The funny part is that if I go to Places>Connect to server and type my mybook ip address, my laptop can connect and I can browse the files. I really dont know what is the problem. My firewall is down so I dont think that is the problem. If anyone can help me with these because I know im able to connect to my mybook but i am unable to connect to any other laptop or my WD-Tv live.

today i was trying to activate KMS by adding:
Code:
radeon.modeset=1
to grub.
it worked fine, and fixed the black-box bug in cairo-dock, and i finally had a nice graphic bootscreen again.
but another bug occured: im running dual-screen setup, my notebook is connected via vga to a dell 22 inch widescreen TFT.
by default both screens running with 60hz and no problem.
now, after activating KMS it happend that, while the dell monitor still ran 60hz, the notebook screen was running with 61hz! it was shown in the monitor-options.
the notebook monitor was therefore flickering a bit for 5 seconds, than running fine for another few seconds. then flickering again. (obviously, as 61hz is too much when it should run with 60hz!)
so my question is: how can i activate KMS again and have both of my screens running with 60hz again? is there an option?

I have a freshly installed Ubuntu 11.04 on a laptop computer with an ATI card. I have installed the latest ATI proprietary drivers 11-6 manually, by downloading them from the ATI website, creating .deb packages and installing them. Everytime I connect an external monitor, the system seems to go into kernel panic. The laptop monitor becomes black; I can see the mouse cursor, but it does not move. The external monitor also remains black.
The system does not respond to any command, neither Alt-Ctrl-F1 nor the Elephants key. I have looked at /var/log/syslog and /var/log/Xorg.log*, but none of these end with an error.

I have a netbook (Acer Aspire One) I'm running Slackware 13. and usually, I prefer to connect an external monitor. When I switch my machine on with the monitor connected, the display is duplicated on both screens and since I just want the netbook's screen to be off and only see the display on the external monitor, I can doxrandr --output LVDS --off
Great! However, it's a hassle to do this every time I log in and I'd like to automate the process if possible. I did some googling and I found that if you want to automate xrandr commands, you can put a script in /etc/X11/Xsession.d/ (see this). I wrote the following script to automate my xrandr commands and since the Xsession.d directory didn't exist, I tried creating it. The script was called 45custom-xrandr_settings, as the one on the RandR wiki is called the same.
Code:
#!/bin/bash
# Check whether the external monitor is connected

I am using my laptop, hp compaq6710b with an external screen connected to that with the extended desktop options, which really increases the efficiency for programming and reading documents and doing changes.
I was wondering how to connect a 2nd external monitor to the laptop. Laptop has one VGA output apparently which is connected to the external monitor for the moment. I saw that there are some converters from usb to DVI-D or VGA. I guess these connectors can make the conversion I am looking for. Anybody used these connectors with debian to get an extended desktop on 3 screens(2 external monitors + laptop screen).

I have a mac book pro 5,3 with the nvidia gforce 9600m. After getting Ubuntu installed as a dual boot, I wish to use an external monitor while using Ubuntu. (it doesn't have the problem with OS-X) The external monitor is a samsung syncmaster 192 n. when I connect the other monitor and press 'detect display' both go grey creens(the external already is of course). My lapton screen will not recover until restart either. I need this monitor to run a numerical mesh 3d mesh creator that will not fit on my screen alone. Wouldnt be a problem if the creators were software engineers but the program window cannot rescale, and is beyond the resolution capabilities of my 15'' screen alone.

I had my Ubuntu Linux 8.10 Server working fine. I moved the location. The only change was the IP. I changed interfaces to reflect my new IP. Everything works except now I can not connect to my server using my laptop running XP. Before the move I had no problem connecting to the server with my laptop. Windows can see the server but will not connect. Can changing the server IP affect Samba?

I've installed Ubuntu 10.10 on my Macbook Pro 5,5. Everything is running fine with some tweaks. Just one thing bothers me: when I tell Nvidia X Server Settings that I want to use my external screen as primary screen it doesn't put the gnome panels to the other screen, well... sometimes it does after a couple times but most of the time it doesn't.is there a way to automatically detect when I connect a monitor instead of going to the Nvidia settings? Just the way Mac OS X does?

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:

Have just installed Ubuntu 9.10 in Vmware workstation 6.5.1 and unable to connect to external sites, or servers (using NAT). I can ping on host name and IP but can't resolve either host or IP in browser (Receive message the connection has timed out). I can't ping the host (Windows 7 Professional) IP from the guest and vice versa. I use a mobile wireless network card, and my Windows operating systems work successfully in vmware. Currently in my VMNet8 properties I just have Obtain IP address and DNS Automatically (same as host).
