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
Launching fallback window manager
My /etc/X11/xorg.conf looks like this:
Identifier"Configured Screen Device"
Device"Configured Video Device"
I am using an external monitor on a laptop whose default screen is dead. This works fine with Gnome or KDE, but when i do a switch to console (ctrl-alt-fnX) my monitor loses it's signal, and i wind up with a black screen. Alt-fn7 gets me back fine, but i am really missing the console...
Computer switch monitor key (fn-f does nothing, even tho it works fine when in Gnome.
A few days ago, I did a clean install of Ubuntu 10.10 onto a Mac. I dual-installed with Mac OS, and everything appeared to be going very smoothly. until I connected to an external monitor (a video beamer I use in my classroom). This led to:
a) the external monitor apparently being considered the primary monitor, and
b) compiz effects being disabled.
I addressed (a) by modifying the file monitors.xml in [me]/.config. (Before that. I had created a startup entry xrandr --output LVDS1 --primary. That also seemed to work; after changing monitors.xml, however, I disabled that startup entry, as it now appeared redundant to me.) Generally and for all I can tell, my actual computer screen is now correctly identified as the primary monitor -- from the moment I log in, at least. The log-in screen itself, though, appears on the external monitor, or not at all when that monitor is turned off.
This is the content of my monitors.xml file: I have not found any solution for (b): when I physically unplug the external monitor and reboot, compiz will run again; but once I plug in the external monitor, it won't.
I have an Acer Aspire One AO150 and am having trouble plugging in an external monitor under Ubuntu 9.10. There were no problems under 9.04. If I plug in an external monitor once the machine is already up, then bring up the 'display' application to activate it, it basically hangs. There are no problem under these circumstances if I have desktop effects turned off.
A few more details after a question below. The machine does not respond to its keyboard commands to switch to an external monitor, nor does it respond to Ctrl-Alt-F1, etc to switch out of X. The pointer is visible on the monitors (at the edge of each) and is frozen as a 'busy' cursor, but with no animation. The kernel does respond to SysReq commands (REISUB).
In the latest attempt I had the external monitor active earlier, then removed it and activated desktop effects. Upon plugging in the eternal monitor then bringing up the display application, it hangs.
Is there any way to put a dual monitor wallpaper on a single monitor configuration using desktop wall? Using only 1/3 or so per wall. Something that will have the effect like the scrolling wallpaper feature on Android/iPhone.
I have persistent video tearing my second monitor (Mitsubushi HDTV). I have tried everything that was suggested with some improvement. I have no issue with tearing if I add the following to my xorg.conf
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 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.
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.
I've been looking into this issue this whole afternoon, but I couldn't reach a definitive conclusion, so I decided to ask. Sorry if it's been explained somewhere else, I truly didn't manage to find it.
I'm running Ubuntu 10.04 on a laptop with Intel 945GM graphics controller. My laptop's screen native resolution is 1280x800. When I'm using only that, compiz runs fine.
When I connect a second screen -- a TV with native resolution of 1360x768 -- it doesn't work because the virtual screen resolution exceeds the maximum 3D texture size [2048x2048].
Lowering the resolution of both screens until the total size is less than 2048x2048 works, but it's really ugly and sacrifices a lot of screen real estate.
My question is: is there any way whatsoever to make compiz run only on my laptop screen and disregard the other one? An even better solution would be to run two instances of compiz, one for each screen, but I'll settle for having it on my laptop screen only, if possible.
using compiz under Ubuntu 10.4 on an eeepc, with all its rotating cube lovliness. All was well until I used the eeepc for a presentation and used the "monitors" app from the System -> Preferences menu. Now none of the compiz effects work. how to get compiz working again?
buntu user but this time I'm planning to remain so I would like to solve this little problem, which is the following:I have a MSI Wind U100 running Ubuntu 10.04 LTS... everything works fine, both Compiz and Emerald, but when I plug in an external screen (Samsung SyncMaster 2232BW) Compiz simply gets disabled, if I try to re-enable it a pop-up shows up saying "Searching for video driver..." (or something similar) and it reverts "None" againWhen I unplug the external screen and try to re-enable Compiz it runs fine like it should, I've read elsewhere to run "compiz --replace" but it does nothingI thought something like:Plugging in an external screen requires Ubuntu to use a different display driver which doesn't support Compiz
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?
i know this sounds stupid but on my xubuntu i cant connect my laptop to a monitor it connects on bootup so i can see the startup but i cant change after. ive tried a lot of things and i googled it and searched but no answer i have xubuntu 8.04
My original intention was to install a distribution of Ubuntu onto an external hard drive so i can use it on different computers. I first downloaded and burned a copy of Ubuntu 10.10 and booted my Acer laptop to it. I then plugged in my external hard drive and tried to install ubuntu onto it by partitioning the external hard drive. After I did that, I booted from the external hard drive on my laptop and it ran the new distribution i created. However, when I tried to boot it from a different computer it said something like "partition not found." So the next time I tried to install ubuntu onto the external hard drive with out partitioning it, using the entire drive. This is what started to cause problems.
Now when I start up my laptop without the external hard drive plugged in i get "error: no such device: xxxx..... grub rescue>. When I start it up with the hard drive plugged in a grub comes up with the new installation, my old ubuntu installation, and my old windows vista.
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 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.
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 recently tried to plug in a second monitor to my graphics card in an attempt to mess around with a dual monitor set up. This created a duplicate effect (which I expected at first) but downgraded my original monitor to the second monitors max resolution. Now my xorg.conf appears to be blank and I dont believe my fglrx drivers are working anymore.
When I try to start compiz from bash I get the following:
When I attempt fglrxinfo:
I'm running Kubuntu, Karmic AMD64 ATI Radion x1350
What could have happened? All I did was plug in a second monitor and restart!
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?
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?
