Slackware :: How To Configure External Monitor In Laptop
Sep 6, 2010
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 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 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 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'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 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 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 a laptop lenovo T410s, using RHEL 5.6, 2.6.18-238. I'm trying use the external monitor as dual head using the system-config-display tool, but the generated xorg.conf fails:
Monitor autoprobe results
Monitor autoprobe failed.
And if I boot up with the monitor attached using the old single head valid xorg.conf, both screens stay blank. It works only with the external monitor cable disconnected. I don't know what else to try.

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

I have an external monitor connected to my laptop (extended display). I always drag the Totem player from the laptop screen to external monitor to watch video files. I wonder, if the Totem player can be set to open in the external monitor automatically, everytime I open it?

I was transferring some files from my external USB hard drive onto my laptop (running 64bit Karmic), and my laptop froze up for whatever reason.Everything on the screen stopped and the Scroll Lock and Caps Lock LEDs began flashing.Not knowing anything else to do, I hard booted off with the power switch.At this point, I was concerned if anything on either hard rive would be damagedI booted my laptop back up, and all seemed well until I trued to open my Documents folder.For some reason, Ubuntu will no longer open any folders at allI can't click on ComputerDocuments, Music, etc. When I do, a tab opens in the taskbar that says Opening folder. It stays on screen for about 20 seconds, and then goes away and the folder never opens.The weird part is if I open gEdit and try to load a file, I can see and get to everything.

I have a display problem since updating to Slackware 13.37. Everything was fine on Slackware 13.1, but when I switched to 13.37 some piece of software came up with the wrong monitor size. I have a 1600x900 LCD monitor but the X screen came up as 1024x768 with blackness on either side of it. Under Slackware 13.1 the X screen came up as 1600x900 as it should without any prompting from me; I didn't even have an Xorg.conf file. I tried using the Xorg.conf file which was needed and work for older Slackwares, eg 12.*, but it didn't work. (Saying it didn't work is a gross understatement! That old Xorg.conf completely screwed up mouse, keyboard, and monitor; the screen was flashing and nothing worked. The only way to get control back was to SSH into the machine from my laptop and reboot. Killing the X server via that SSH console did NOT the flashing or get me back to my console login; only reboot worked.)
I find I can get the screen to be the right size manually by going through KDE's "System Settings" --> "Display and Monitor" --> "Size & Orientation", then disabling "LVDS1" and setting VGA1 to 1600x900. The size of my odd-sized monitor is being correctly detected for the "Auto" choice. Upon reboot LVDS1 stays disabled but VGA1 reverts to 1024x768 so I have to do this each time.I've done some search of the on-line literature regarding the error messages I am seeing in the boot log.
People are suggesting changing all kinds of things to alleviate the side effects of the "conflicting" error message above, even modifying GRUB parameters (which won't work for me since I use LILO).So, I have a manual work around which I must do each time I log in. Does someone know how I can get X or KDE to force 1600x900 upon start (while Linux/X/whoever find and fix the problem) or does someone know of a real fix?

Now i have 64 bit computer i installed Slackware 23 64 bit on it. i followed Alien Bob's multi lib how to and installed needed libraries one by one. everything is fine expect wine configure script can not find some libraries needed: libgsm, libmpg123, libopenal, libxcomposite.
I have already installed 32 bit compatibility packages and used /etc/profile.d/32bit.sh as recommended in Alien Bob's howto. configure -- does not really list anything for pointing for libraries.

I recently tried to configure a second monitor on 10.4. Since then I have not been able to log into the desktop. I get the video card at boot, then the ubuntu splash screen and then nothing!
How do I correct this? The video card is nvidea and I guess the configuration file is corrupt but I can see no way to reset/install this.

I have a small problem after connecting a LCD monitor to an acer netbook. I need to figure out how to make the monitor the primary. 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.

I am trying to view my pc on my new flat screen but am unsure of the settings. I am using ubuntu 10.10. I have been trying (and on ocassion succesfully, but never really understood what I have done) to view my pc through the monitor option under preferences. 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.

After the login screen, my laptop screen is active but the external LCD monitor hooked to my laptop goes blank which was active to that point.
Here are quite a few details which might help you in diagnosing the problem
alt + clt + f1 takes the monitor screen to command line but alt + clt + f7 fails to bring it back to GUI. The monitor just freezes!!
