Ubuntu Multimedia :: Triple Monitor Xinerama - Cursor Movement Limited
Jun 6, 2010
UPDATE: I can get the wrapping to stop, but it offsets the image between monitors. It's like the center monitor's image was stretched upward, distorting the alignment with the side monitors, rather than just providing additional space at the top. If I switch it so the two side monitors are 120px lower than the center, (as i had it in 9.04) then the wrapping issue occurs again. This is frustrating. I could use some help. (64-bit Ubuntu 10.04)
After lots, and lots, and lots of googling, configuring, experimentation, and even unplugging and replugging, I finally got all 3 monitors working like I had them in 9.04... Or almost. The center monitor is larger than the two side monitors, being 1920x1200 compared to 1920x1080. When I move the mouse pointer on the center monitor, it hits a ceiling and disappears right around that extra 120 pixel area on top, and can be seen at the bottom of the screen.
I'm using Mac as a main machine and Ubuntu Netbook as a secondary. Although synergy gives me a good control over Netbook when it works without external monitor, but when I activate VGA monitor, I can only move around the limited region (details are below).
Phenomenon: Cursor can move in the external monitor's screen. No way to move cursor into the netbook's screen via synergy (it's possible from local touchpad/mouse) In the external monitor's screen, curosor moves only within limited region, which I'm guessing is as large as the size of netbook's screen.
Configuration: Use dual screens (uncheck "Same image in all monitors" in the tool "Monitor" on Ubuntu)
I use 2 monitors under Ubuntu 9.10, but I have them set up in a unique way. The primary (CRT) faces me on my desk, but the other (widescreen LCD) is turned away from me, because I use it only to watch movies from my couch. My video card is an Nvidia GeForce 9800 GTX+, using the proprietary Nvidia driver package, with Xinerama turned on, so the desktop extends across both displays. Given that setup, is there any way to control which display applications open upon? Several apps have started opening on one display or the other, seemingly at random. Further, some apps start on the primary display, but open their subwindows on the secondary display. It's very annoying, because I can't see the second screen, so I can't drag the windows back to the primary desktop.
I would also like to have VLC Media Player (or any other app) always open on the secondary screen, on purpose. I almost never watch movies sitting at my desk, but rather from the couch. I placed a VLC launcher icon on the secondary screen, but when started it opens on the primary display. (If you're wondering how I can click on anything from my couch, I have a wireless mouse there in addition to the wired mouse at my desk. It's my "remote" since I don't have a TV. Xorg will quite happily support 2 or more mice simultaneously, I discovered.)
Did a new install with a system that worked well on 10, with Xinerama. I have nvidia 9500 GT cards, but I dont think its driver related. Screen 0 is the center Screen 2 is to the right And Screen 3 is to the left.. When Xinerama is disabled things work flawlessly, but not using Xinerama is a killer to me. The nvidia configuration utility generates the following xorg.conf when Xinerama is disabled. It gets the locations right and the mouse moves correctly between screens.
I would like to increase the speed of my cursor movement. For example, when I press and hold the left or the right arrow when in terminal or a text editor I would like the cursor to move faster. I have tried kbdrate and xset as suggested here:
I'm trying to set up a tri monitor setup. Unfortunately I must use 2 cards, one an AMD HD4350 and a PCI Geforce FX200. (Old skool I know) Due to the restrictions, I am forced to use the open source drivers (else nvidia glx will clash).
1: Use XRANDR to span the displays (this is what I did previous to the introduction of the third monitor and nvidia card to my system) I tried to do this, by setting up a second X screen on the NVIDIA card, disabling Xinerama; but after much googling I can't figure out the syntax for panning across 2 screens (X screens) in XRANDR, even tho it's >1.3, which supposedly supports multi card output.
2:Use Xinerama, sacrificing randr, and composite extensions. I also attempted to do this, with some limited success. I could get the NVIDIA screen to be right of the ATI, but I couldn't get 2 independent outputs running on the ATI card, even with "ZapohHeads" appended to one of the device sections for my ATI card.
I have some very strange issues with my tripple monitor setup on debian wheezy. I have acer aspire V3 laptop with i915 Intel (Intel® HD Graphics 4000) as part of i3 and nvidia GT 740M which I never managed to get working with or without optimus to any degree whatsoever. What I want is a reliably working triple monitro setup. I have 2 additional DELL u2412m monitors which I did manage to get to work on few occasions by more or less randomly turning stuff on and off via lxrand and KDE systemsettings (so I do knwo for a fact that tripple monitor setup works). Arandr doesn't work, and executing xrandr from cmd doesn't work. I can relatively easily get the 2 monitors to mirror each other, but to get them to work separately is extremy difficult. It's always the same error but the well known crt. For example:
When it did work I copied arandrs script in hopes it would work, but it doesn't. Obviously, here is the issue that the crtc can not be configured so if somoen could tell me why and how to get the damn thign to use a specific crtc it would be awesome. Also, I noticed that when I hit "identify monitors" in KDE systemtools, it would say VGA HDMI for both VGA and HDMI outputs.
Here is xrandr output from when it worked:
Code: Select allScreen 0: minimum 320 x 200, current 5760 x 1200, maximum 8192 x 8192 LVDS1 connected 1920x1080+1920+0 (0x46) normal (normal left inverted right x axis y axis) 382mm x 215mm Identifier: 0x42 Timestamp: 143521 Subpixel: horizontal rgb Gamma: 1.0:1.0:1.0 Brightness: 1.0
Here is now:
Code: Select allScreen 0: minimum 320 x 200, current 3840 x 1200, maximum 8192 x 8192 LVDS1 connected 1920x1080+1920+0 (0x46) normal (normal left inverted right x axis y axis) 382mm x 215mm Identifier: 0x42 Timestamp: 5817108 Subpixel: horizontal rgb Gamma: 1.0:1.0:1.0 Brightness: 1.0
This is a triple-monitor setup with two video cards, where the mouse pointer gets "stuck" if it tries to cross from one video card to the next one. It worked correctly in openSUSE 11.2 and doesn't work in openSUSE 11.3 with the same xorg.conf. This is a 64-bit openSUSE 11.3 with xorg 7.5-11.3 (the openSUSE prepackaged version). I've already tried NVidia drivers 256.53-16.1 (the openSUSE NVidia repository version) and 260.19.12 (the latest off of the NVidia website).
This is the same xorg.conf that I used successfully in openSUSE 11.2. I tried a new automatically generated xorg.conf using nvidia-settings and it had the same problem. This forum won't let me upload the relevant files, but here: [URL] is a tar-ball with my xorg.conf, Xorg.*.log, /var/log/messages, and the NVidia debugging output.
I'm having some issues getting my two monitors (both 1600x900) to work well with Xinerama. The first thing I'm having trouble with is getting 1 wallpaper to span across both monitors..from what I've googled it's sounds like I'm not the first either The 'span' function in the change wallpaper window doesn't do it. The second thing is that I would like the panels to stretch across both monitors well, or at least be able to create another panel on the 2nd monitor which I can't do now.Here's my xorg.conf file:
Today I bought a new monitor (IPS236V) to use it to watch movies and tv while I'm working on the other one.. I thought it's the best to activate Xinerama which could be done easy via CCC. But I'm not able to change the resolutions now as these panels are disabled in CCC. The first monitor is set to its native resolution, but the second is something lower.How can I configure both monitors to there native resolution?
I would like to adjust Xinerama to place 1 desktop on each of my 2 monitors and not stretch a single over both. With the current set up there is a problem with window placement upon opening new widows or context dialog boxes. I realize that I could adjust placement properties and select window placement with the mouse but this is still lacking in productivity. My monitors are not next to on another so this is more of a problem than it seems.
I have recently upgraded to Lucid with a clean install. I have two NVIDIA GeForce 7300GT cards with 3 21" monitors connected to them (two to card 1, 1 to card 2 although sometimes I plug in my projector so its 2 to both).I previously had Karmic installed and was able to use all three (or four) monitors without any problems. Now, however, Nvidia-settings only recognizes the one GPU. It will only recognize one or the other. If I edit xorg.conf so that Screen0 is on PCI:3 instead of PCI:1 (where my two cards are located) It will switch over to that GPU, but I can not get both to work together at the same time.
I have tried using my old xorg.conf but it does not work. I've tried editing the current xorg to have one monitor running off of each card and it will not work.
I am running Fedora 12 on a T400 Thinkpad. When connector my external monitor prior to powering on the computer or if I restart it, I get a lot of resolution choices from xrandr. See below.
Code: $ xrandr Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192 LVDS1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 303mm x 190mm 1440x900 60.0*+ 50.0 1024x768 60.0
Is there some daemon I need to restart to detect the monitor resolutions correctly, or is there a module I can reload?
There seem to several variables to reproducing the behavior. If I restart without the laptop without the monitor plugged in, log in, and then, plug the monitor in with the monitor powered on prior to plugging, all resolutions are detected properly. However, if I plug the monitor in with it powered off, then power it on, I only get the few options shown in above. Once I get the reduced number of options, it seems to stay that way till I restart regardless of how I unplug the monitor.
I have found a work-around by just forcing the modes with xrandr --newmode and xrandr --addmode, but I would much rather have the modes autodetected.
I have an Acer Aspire One Netbook, and I have the Ubuntu 9.10 Netbook Remix installed. I have tried using Cheese to capture video and it captures maybe 2 seconds of movement, then goes black and/or the image freezes. I can take photos just fine, but video capture seems to be impossible. Any help?
I have been using AWN for years, having a startup script to run multiple instances of AWN and position it on each monitor correctly. This has worked fine but today I decided to upgrade the version of AWN. The only problem now being that the new version doesn't support multiple instances of AWN to be open at once.The new version of AWN does have an 'Add dock' button but that's no good as my setup isn't Xinerama so each monitor is it's own workspace, meaning I can't position the dock far left, because far left is the edge of the current monitor.
The ideal solution here would to be able to run multiple instances, as I can force each instance to a monitor with DISPLAY=0:1 etc.If anybody has any ideas on how to have AWN on each of the 3 monitors then please let me know.
What graphics card will support (without too much fiddling) three 24" displays? I just got rid of my mac and am now going to get a linux desktop. I am not sure what distro yet, probably fedora although I am thinking about arch. I have some experience in linux, although nearly none when it comes to hardware configurations. I have two 24" BenQ monitors (DVI and HDMI inputs) and will buy a third 24" display with the pc.
Now I have been looking at some forums about triple monitor setups, but they are almost all about troubleshooting existing hardware compatibility issues. I guess I am at an advantage since I haven't bough any hardware yet, so here is my question. What graphics card would you buy to support 3 24" displays together (meaning that I want to be able to drag windows from one display to the next). I was looking at the ATI HD 5770 and some mention of the eyefinity stuff.
After working on trying to get my 3 monitors to work with Ubuntu 10.4 and my ATI Radeon HD3200 (IGP) and HD4850 cards, I just had to share the xorg.conf. I am using the default open source drivers that came with 10.4 and I kept KMS enabled (it wouldn't work without it).
I have done a fresh install of ubuntu 11.04. Everything is fine, Ubuntu seemed to be using the opensource ati drivers upon first boot. Then prompted that I install the ati catalyst control center/drivers from additional drivers which I did.Again smooth sailing untill I decided to enable my HD tv (hdmi) as my secondary screen. This again worked fine cloned. But I could not enable extended. The option is available but requires xinerama to be enabled.
After restarting I could not login. Read up on this and others have has this issue with different cards. I proceeded to login to ubuntu (no effects) session and then swtiched off xinerama. (this did work in this session). The issue is getting it to work with unity. Logged back into unity now but I don't know how I can enable dual screens in extended mode. There are recomendations on other threads advising to use the open source drivers. But these don't work correctly. The card I am using is an ASUS EAH5570. This I believe has the radeon 5570 chip.
I have a ASRock ION 330 with 512 Mbyte shared graphics memory. I use the 256.44 closed source nvidia drivers and have a Xinerama display consisting of one Asus 1440x900 monitor and one video projector with displaysize of 1280x720. Display: 1440x900 + 1280x720 in Xinerama
I have tried with and without desktop effects enabled, and I have followed the http://tombuntu.com/index.php/2009/0...thout-tearing/ guide to manually set the refresh rate to 60 Hz. The sync to Vblank option is checked, both in CCSM and nvidia-settings under X Server Xvideo Settings and under OpenGL Settings, to no avail.
The files I play are MPEG-2 Transport Stream in 720p. Some are and some are not in Matroska containers. I use SMplayer with vdpau enabled. I've made a comparison of Windows Vista and Ubuntu 10.04 below:[URL].. It's not entirely clear from the video, but the end scroller is choppy on Ubuntu and relatively smooth in Windows Vista.
This setup is to be run in a public cinema, and the chopping and tearing is a complete showstopper. It would be a nice showcase to have Ubuntu in the wild like this, but it can't be used if these issues are not resolved.
As of the 1.10 X server release, the Xinerama rendering multiplexer and Composite extensions no longer conflict.[URL].. So does this mean that if I use X 1.10 or later, Xinerama and composting can work even over two GPUs and four monitors?
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.
Just a day ago I did a clean install of 10.04, after wiping the disk clean of 9.10. So far everything's working great. Except for my old dual-screen configuration. A year or two ago I badly wanted to have 2 monitors, where both would share the same desktop/workspace allowing me to drag windows back and forth between the two. After a lot of research, I finally was able to put together (although a probably quite sloppy) xorg.conf file that did the trick for me.
My case is somewhat unique in that my left monitor is horizontal, while my right monitor is rotated 90 degrees, and is vertical. In 10.04, my old xorg.conf file sort of works, but I have problems on my right, vertical screen:
- when I move my cursor onto the vertical screen, when I try to move it above where my left, horizontal screen's boundaries end, my cursor jumps down to the bottom of my vertical screen. I can't access anything with my cursor above this boundary on my vertical screen. Note that my vertical screen's bottom is in aligned with my horizontal screen's bottom, and that the vertical screen sticks up above the horizontal screen, as both have a 1680 x 1050 resolution/widescreen aspect ratio.
- however, it appears that only my cursor is having issues accessing the upper part of my vertical screen. When I maximize windows in this screen, they properly fill it up entirely like they should. (but I still can't access the top parts of these applications with my cursor).
So obviously there must be some boundary managing where my cursor is allowed to go, and another set of rules defining the boundaries that the windows themselves can be shown/take up. Also note that because of my right monitor being rotated vertically, I'm forced to use Xinerama. Can someone help me go through my xorg.conf file, below, to help me get this "simple" cursor issue fixed? I'm sure it's just one minor thing that has to be changed, but I'm not sure what:
Code: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 1.0 (buildd@palmer) Sun Feb 1 20:21:04 UTC 2009 # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 1.0 (buildmeister@builder57) Thu Jul 17 18:39:19 PDT 2008 # xorg.conf (X.Org X Window System server configuration file)
I recently switched from Ubuntu to Lubuntu on my Acer Aspire netbook. When I had Ubuntu, in System Preferences I had a Sound mixer that would allow me to set the volume beyond 100%. It simply said "Sound" and was different than the applet feature. Both were preinstalled. With Lubuntu, I seem to have lost this option. I went through and installed Gnome ALSA Mixer along with Pulse Audio Control, but neither does what this simple volume control feature on Ubuntu did. My speakers are horrible, and the previous "Sound" feature really let me crank it up a bit. I'm not trying to blow my speakers out or anything;
I cannot install Ubuntu 10.04, or even boot into the live CD. I'm not an expert, but I've used Ubuntu for several years, and I'm pretty sure I'm not doing anything stupid... Here's what happens when I boot with the Ubuntu 10.04 live CD: I get a purple screen with just an accessibility(?) symbol at the bottom (this lasts 15 seconds). The screen goes black, with a flashing cursor, then changes back to purple, this time with an Ubuntu logo, with 5 dots acting as a progress indicator (this lasts about 1 minute). The screen switches to standby. The CD drive continues to make noises for another minute or so, then stops.
I physically removed my graphics card (ATI Radeon HD 5770), and plugged the monitor straight into the VGA port on the motherboard. Now the CD boots up fine. I could try installing Ubuntu at this point, while my graphics card is unplugged, and then plug my graphics card back in, and see if it starts working then.
Currently I have two 1920x1080 screens running in Twinview on my Geforce 275 graphics card. Want I want to do is a quick simple way of disabling my secondary monitor when playing video games or using xbmc to watch movies, etc. I've tried a few applets but they require the xandr function which I think Nvidia doesn't support.
Is there a way to disable this quickly other than loading up nvidia-settings and disabling the monitor everytime. I don't really want to use two seperate x sessions and xinerama due to the fact you can't use compositing.
I am using opensuse 11.3 on a computer with limited internet connectivity.Can anyone provide a list of essential libraries which would be enough for most applications. I get errors due to library missing while running configure script.
Anyway, just installed 10.04 desktop on a 4,1 Macbook. I've pretty much got everything to where I like it. My only real problem is the track pad/mouse not working right. Unless I move the the mouse perfectly vertical/horizontal the mouse starts zigzagging like crazy. The slower I move the mouse the more prominent the problem seems to be. I've tried playing with the mouse settings under preferences but nothing got it working smoothly.
I've been using Ubuntu off and on for about a year now, and my problem is that when ever I move a window on the desktop it gets all flickery and choppy. I have 4 gigs of ram, an AMD Athlon X2 processor @ 2.70 ghz, and an NVIDIA 9500 GT graphics card with 1 gig ram. I have the recommended NVIDIA driver installed. Anyway I really like Ubuntu but this issue is annoying and makes it look like crap. I don't have this problem with Windows or KDE distros so maybe it is something with GNOME.
