Ubuntu :: Using External Monitor With A 10.04 Installed Macbook?
May 11, 2010
I'm running Ubuntu 10.04 LTS on a Macbook 3,1 late 2007. I have an HP paviilon f1703 external monitor that I would like to use as the main screen to load the full resolution GUI without using the laptop monitor at all. I've done several Google searches and tried several remedies, and I'm either doing them totally wrong (which is very very possible because I'm such a newb), their out of date, or their just not working for me.

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 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

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?

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.

From some Googling, I've found that you can use Bootcamp to install Linux Macbook.However, I have a Macbook air and do not have sufficient disk space. I was wondering if I could install it on an external drive, and boot it from the Macbook? I think that the problem is the bootloader. But, if I still use Bootcamp to install Ubuntu, it would set up the bootloader, and then I would just install to an external?

I thought it was a driver issue, but after messing around with the ALSA mixer a lot, it turned out that when I enabled headphones(or disabled, honestly not sure) that my headphones worked, and when I took them out the speakers worked. Then when I rebooted for whatever reason, only the speakers(built-in) worked. Really, I'm not sure why this is.
When I got them to work there was a switch for the headphones in the graphical mixer(which is what I used, not the ncurses[?] ALSA thing), but I can't seem to find that anymore. It's not a major issue, it just puts me off watching videos and listening to music because my laptop speakers are really low quality. I'd go out to buy a pair of external speakers, but obviously with the audio jack not working, this could be problematic.
I guess I could buy USB external speakers but then the probability of Slackware having pre-installed audio drivers for a cheap generic brand of speakers is so low it doesn't justify the effort of going and buying some, nor the money that would be spent. Willing to enter any commands/w.e. I'll be on Slackware all the time 'cause I need a Linux system right now.

I recently upgraded my MBP motherboard which evidentially has an advanced graphics architecture that employs both the NVIDIA GeForce 9400M integrated and NVIDIA GeForce 9600M GT discrete graphics processors. I had no problems powering my external monitor until the MB upgrade. Now I get an xorg.conf conflict where

Manually mount or fix my external hard drive. I can't format the drive because I have important data on it. The drive is 1TB Select USB 2.0 Desktop Hard Drive from Iomega. When I plug it in, a message appears that reads:
"Error mounting: mount exited with exit code 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb2,missing codepage or helper program, or other error. In some cases useful info is found in syslog - try dmesg | tail or so".
Also, I plugged in the drive, typed the command "sudo fdisk -l" in the terminal, and received the following:
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.
WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.
Partition table entries are not in disk order

Earlier this year I encountered a problem with my external hard drive; it would not mount automatically and I kept getting an error message. Last time I was able to fix it by typing in the terminal 'sudo fsck /dev/sdb2'. Once again it's not mounting automatically and I'm not even getting the error message. I can't format the drive because I have important data on it. The drive is 1TB Select USB 2.0 Desktop Hard Drivefrom Iomega. Also, I plugged in the drive, typed the command "sudo fdisk -l" in the terminal, and received thefollowing:WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

Yesterday I installed Debian 6 on my Macbook, with dualboot. Everything is working fine, except for the keyboard. As I'm typing, I see the mouse arrow moving a bit and strange things happen, such as text under the arrow being highlighted or clicked.
Other things as Right-Click, selecting text and other mouse-related events also happen. Pretty much all the mouse events are randomly fired while I'm typing on the keyboard.
It's being really hard to type like this. Anyone have any ideas of what might be the cause and how I can fix this?

i have my pc connected to my 24 inch lcd monitor via DVI and my laptop via VGA. i noticed ubuntu is slightly more blurry than the pc. would the difference likely stem from the manner of connection or faulty drivers on ubuntu's behalf?

My experience with external monitors in Linux is harrying at best. It's getting better, but it still ain't perfect. My current experience (I have an nVidia card, with nVidia drivers, on a Vostro laptop):
Turn on computer (booting Karmic).
Connect external monitor
Click on System->Preferences->Display
Redirect to nVidia's tool
Perform at least 8 more clicks to enable secondary monitor.
Realize resolution isn't optimal and set it with another few clicks.
Click Apply
Accept changes
Quit, then really quit, the app.
I always have to set the resolution, it doesn't detect it automatically. The main screen is *always* on the external monitor no matter my settings. I'm screwed if I unplug the monitor but forget to go through steps 1-8, this time disabling the external monitor. I have to replug it in, then turn it off, then I can unplug it. If I unplug the external monitor and plug in another one (going through steps 1-8 twice more) with different resolution capabilities (e.g. a projector), the settings get all messed up again.
Why can't adding an external monitor be automatic? It nearly is on OS X for instance. I plug it in, and it automatically detects the monitor and makes it a secondary monitor, or mirrors them, or turns it on and turns off the laptop screen. All the while being consistent about it. When I unplug the monitor, it knows instantly that I've done that, and reconfigures the laptop screen once again.
I imagine the answer is because no one has stepped up to do it yet, or it's in progress. So my question: what *is* the state of external monitor codes in Linux, and are there any plans to implement them in Lucid? Further, what would be a project, with *user friendly* context, to which I could tune in?
Or, am I not aware of the "right way" to do it?
I define user friendly as roughly the level of kernelnewbies.org . That is, kn.org is my gauge of what I can understand.

I am using a Asus UL30A laptop computer. I just performed an upgrade from 9.10 to 10.04. I remember running into this problem before, but I forgot how to fix it. The problem is, when I plug my laptop into the external monitor with my laptop screen turned off automatically when I first log in, I do not see the mouse cursor on the external monitor! The mouse cursor is still here, although invisible - if I do a right-click, the property menu will come up. My current workaround is simple- if I switch to the next workspace (by pressing Ctrl-Alt-right arrow), the cursor will appear from then on.

I run Ubuntu on a MacBook Pro with an external monitor connected. But currently the external monitor only works with one user account. The External gets no signal and the laptop display is used on the login page. Is there any way of having the login page and possibly startup displayed on the external at all times for all accounts.
System > preferences > Display Doesn't work for me, I use NVIDIA X Server Settings

I have a Hp dv5000 Laptop (not that it matters) with ATI 200M graphics chip and Ubuntu 10.04 LTS. Compiz works perfectly on my laptop screen. But when using my 23" Monitor it just doesn't. If I try enabling desktop effects it tells me it can't. Through terminal ( runnning 'compiz')I get the following error:
compiz (core) - Fatal: Root visual is not a GL visual
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

I have an external monitor at work, but not at home. I take my laptop home and when I come back the settings are off. My monitor is above my laptop, so I have to rearrage displays and save every time its plugged in. Isn't there a system file or something somewhere that I can write to and save the current state as the default?

I just install Ubuntu OS 11.04 recently to my HP Mini 110 netbook. When I try to display on my external 20inch samsung monitor. I get the black borders as shown on the pic. Resolution of 1024 x 768 or higher will cause the problem whereas lower resolution will not have that black border.

I just upgraded my Ubuntu V10.4 LTS to Ubuntu 11. After that, I lost my external monitor and I cannot find those usual "preferences", "Administration" navigational menus on top of the screen.
Stumbled into Multiple Monitors under System, but it didn't detect the second monitor. However, the 2nd monitor was active and with system startup messages displayed there during reboot. But as soon as the desktop appear, that 2nd monitor lost its signal.

How can I detect when an external monitor is connected in linux? I need to run various scripts to set up my workspace. Is there some clever way to kick off a script when the monitor state has changed? I'm using the Nvidia display driver.

I have an Asus eee901 netbook and it's got an Intel 945 graphics card. If I boot it up, log in, attach an external monitor and then open the Display Settings dialog the screen goes black and the laptop appears to crash. Leaving it for a minute or two does nothing.
However, if I boot up with the external monitor attached then I can open the Display Settings dialog and configure both screens.
This is quite annoying as I've got to reboot if I want to connect an external monitor.
Additionally, if booted with the monitor attached and I choose a configuration where the width of the combined screens is greater than 2048, the screens go black and the same lock up appears to occur. Could it be that the Display Settings dialog isn't checking for the maximum display width the driver supports and is then crashing in both scenarios?

I am running Ubuntu 8.04 on a laptop. I have a 19" Acer monitor and in the past have successfully configured my xorg.conf to handle dual monitor setup with 1024x768 on the laptop and 1600x900 on the Acer monitor. What I have done now is run the laptop through a KVM switch. Due to this, I would like to set the Acer monitor as the primary monitor and just shut the laptop. How can I project my laptop screen to my Acer monitor so that I can use the 1600x900 resolution available rather than just cloning my laptop and using 1024x768?

Ive been wondering about an alternative method for checking to see if an external monitor is connected.
Currently I am using:
Code:
#!/bin/bash
EXTERN=VGA1
if $(xrandr --prop |grep -q "$EXTERN connected");then
echo -e "$(echo $EXTERN | tr -d [0-9]) is e[1;32mconnectede[0m"
else
[Code].....
So, what I am asking is, is there a way to ignore/over-ride compiz's texture size check, a different way to query xrandr, or is there a completely different method I can go about checking if an external monitor is connected?

My laptops screen has recently gained an annoying blue tint, which i do not have the expertise (or money to pay somebody) to fix, so i am using my TV as an external monitor. So what i am proposing to do is purely use the External and leave the laptop monitor off. I am dual-booting Windows XP and Ubuntu 10.04 Devel, In XP it was a simple case of right clicking the Intel Graphics Media Accelorator and choosing the External Monitor option, this then allowed me to set my resolution to 1280x960 and i was happy. (even bigger desktop than before actually)
I cannot seem to find this option in Ubuntu, going through System -> Prefrences -> Monitor gives me the option to mirror the screens, but that leaves me with an incredibly low resolution, choosing to not mirror the screens allows me to set the resolution to 1280x960, but the LCD screen still acts as my main. Is there any way I can set it to recognise the TV as the main, and switch off the LCD like I did in Windows?

I believe I'm right in thinking the type of graphics card I have is relevant somehow to this, so after some googling I think I worked out mine is Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller.

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
