Currently here, audio is available from sockets on the mainboard or from a USB adapter. The ThinkCentre M92p has USB. No monitor here has built-in audio.

Lenovo ThinkCentre M92p driving two monitors.
An M92p has a DisplayPort (DP++) connector and a VGA connector. An old VGA monitor can be connected directly. Any advice about choosing an adapter to connect DP++ to the DVI connector on a 2nd monitor? Any advantage in finding a way to connect two monitors to the one DP++? Thanks, ...

SDDM display manager, two monitors out of order
I have two monitors side by side and they work nicely on my KDE Plasma desktop session. However, in SDDM display manager (login screen) the monitors are in wrong order. Below is a picture of the two situations. Arrows in the picture show how the mouse cursor travels from screen to screen. You need a fixed width font to see my character "art" correctly. SDDM login screen: >+-+ +-+ >| | | | > ---+---> | | ---+--> >| | | | >+-+ +-+ User's KDE Plasma session: >+-+ +-+ >| | | | >| ---+--+---> | >| | | | >+-+ +-+ It's only SDDM login screen so the problem is small but obviously it would be nicer if SDDM would have screens in the right order too. I know that I can add "xrandr" commands in SDDM startup scripts. I also know that I can psysically connect specific cables to specific monitors and change user's KDE Plasma session settings istead of SDDM. But I like my physical monitor hardware in this particular order and I would prefer the least hackish software configuration. My current best idea is to edit /etc/sddm.conf with lines something like: [X11] DisplayCommand=/root/bin/fix-monitor-order.sh And the script would execute "xrandr" with my preferred options and finally run the default setup file /usr/share/sddm/scripts/Xsetup. But that's not too nice for a desktop system. After all a major Linux desktop system should handle multiple monitors without such low-level hackery, right? -- /// Teemu Likonen - .-.. https://www.iki.fi/tlikonen/ // OpenPGP: 6965F03973F0D4CA22B9410F0F2CAE0E07608462 signature.asc Description: PGP signature

This particular configuration has never been tried before as it's a new computer so the Quadro K620 graphics card is new.

I've two different Nvidia Geforce cards (one several years old and one new). xrandr sees all monitor outputs, so configuring card for two monitors is just a single xrandr command. I never had the two Nvidia cards connected simultaneously, though. Just a single card with two monitors. -- /// Teemu Likonen - .-.. <https://keybase.io/tlikonen> // // PGP: 4E10 55DC 84E9 DFF6 13D7 8557 719D 69D3 2453 9450 /// signature.asc Description: PGP signature

I would expect it to be able to drive two monitors with different pictures, and possibly three. If you are using open drivers, `xrandr` should be able to list the available outputs and modes and change between them. If you are using proprietary NVidia drivers, "nvidia-settings" should be able to work for you. -dsr-

Mark Fletcher composed on 2017-01-04 23:30 (UTC+0900): I've seen several people say or imply this in the past. But I have an ignorant question I am almost too embarrassed to ask (almost). Most normal cards have only one connector of each type. AFAIK, those with only one standard connector, unless that connector is a DisplayPort, can only ever be used for displaying the same thing on each screen, typically called mirroring. So how are you plugging in 2 monitors -- one into the HDMI and one into the DisplayPort / DVI / whatever connector??? Many graphics adapters have multiple output ports that can be used simultaneously, and these can typically be configured to produce entirely unrelated things, or different portions of a single desktop too large to fit on one screen. Or do you use a special cable that plugs into one connector at the card end and splits into 2 at the monitor end? Some gfxcards are intended to be used with a special cable that splits the signal into two discrete ports. Those that I have work the same way as cards with multiple output ports. -- "The wise are known for their understanding, and pleasant words are persuasive."

(I would have expected not) You can order all sorts of cards. 2 DVI, 6 DisplayPorts, whatever. DisplayPort, incidentally, can be split to carry several monitor's signals, if they fit within the allowed bandwidth. You'll need a smart adapter for that, though -- $20-80. And many monitors have multiple inputs of different types. -dsr-

spanning workspace switcher across two monitors
Hello Everyone I have used a large number of debian derivatives and unstable but I have never run stable. I am very happy with it and only have one more obstacle to overcome to have the perfect set up. I am one overloaded Dad! I have many things on the go at once. I prefer to use 60+ workspaces. Right now I am stuck with only 36 and I want my switcher to span my dual monitor set up. I have found a solution for gnome 3 but I need one for gnome 2. In Gnome 3, workspaces_only_on_primary can be unchecked but I can't find this setting with gconf-editor. Could someone tell me how I can do this?

Strange problem when using two monitors (dual view) with Xorg
I've been trying to make my brand new second hand tft work as a second monitor to my Ibm Thinkpad T23. The Thinkpad T23 has S3 Inc. SuperSavage IX/C SDR (xorg does support duaview with this chip). My Thinkpad got the latest bios updates, I'm running latest X.org found in unstable (1:7.3+10). The problem is, if I start Iceweasel on the external monitor, it will crash. You can't use the keyboard (NumLock button doesn't work), but pressing the power button will cause Linux to power off, the screens are black. And if I display images with feh, I get weird noises, the same when I set the background. If I play movies with mplayer, I can't play them in full screen, only the original size. These problems occur only on the external screen. The internal lcd is just as usual. I took a screenshot, and uploaded it onto flickr, the noise is seen here. http://farm3.static.flickr.com/2117/2382485843_04abea007a_o.jpg I've been looking around trying to find any help, but I don't really know what to look after.

Setting up one machine with two monitors, keyboards and mice
Hi All, I just upgraded my machine and would like to try something new. I have a spare pci slot, graphics card and monitor. I am thinking about buying a usb keyboard and mouse. What I would like to do is setup the second monitor keyboard and mouse to work like a second machine. With my basic understanding of XFree86, I would guess that it is possible.

X problems with two monitors
Hello all, i have two monitors (2x 1024x768) on my debian 3.0 with X 4.1.0.1 and WindowMaker 0.80.0. I configured the xinerama mode and most all works properly. When i set a scaled backround picture its being resized to 2048x768 but the right monitor shows the same left part of the picture that the left monitor shows. Through a transparent window like Eterm the picture on the right side is correct so if i fullscreen the window on the right side the full picture is correct. Has anyone else experienced this? How can i resolve this? Thanks for your help, Andre -- Yoda of Borg are we: Futile is resistance.

Is it possible to run two monitors using two video cards on one box? If so, I presume you run two XServers (one for each). How do you switch input focus (mouse and keyboard) from one to the other?

Re: two monitors
hi, Ok guys -- I have a second monitor, and wouldn't mind buying a second video card if it would allow me to use two monitors at the same time. I don't know where to start looking for information on this. as usual http://www.xfree86.org My current video card is an AGP ATI [EMAIL PROTECTED] I am running XFree86 Mach64 3.3.5-1. Do you guys have any suggestions for a second video card (I think it would need to be PCI... :) it is not yet in stable xfree release (3.3.5) but it is planned for Xfree 4.0 release. If you are brave enough you should buy Matrox PCI card, grab latest xfree snapshot (3.9.16) and try it. From 3.9.16 Release Notes: ... 2.5. Multi-head Some multi-head configurations are supported in this release, primarily with multiple PCI/AGP cards. However, this is an area that is still being worked on, and we expect that the range of configurations for which it works well will increase in future snapshots. A configuration that is known to work well in most cases is multiple (supported) Matrox cards. One of the main problems is with drivers not sufficiently initialising cards that were not initialised at boot time. Normally only the primary video card gets initialised at boot time. Some combinations can be made to work better by changing which card is the primary card (either by using a different PCI slot, or by changing the system BIOS's preference for the primary card). We are investigating options for ``soft-booting'' secondary video cards to deal with this problem, and we've had some very encouraging results. 2.6. Xinerama Xinerama is an X server extension that allows multiple physical screens to behave as a single screen. With traditional multi-head in X11, windows cannot span or cross physical screens. Xinerama removes this limitation. Xinerama does, however, require that the physical screens all have the same root depth, so it isn't possible, for example, to use an 8-bit screen together with a 16-bit screen in Xinerama mode. Xinerama is not enabled by default, and can be enabled with the +xinerama command line option for the X server. Xinerama was included with X11R6.4. The version included in this snapshot contains many bug fixes. This is an area that we are still working on, and we expect it to be improved further in future snapshots. Known problems: The Xinerama layout doesn't match the layout specified in the config file's ServerLayout section. It appears that there are still some bugs that cause unexpected behaviour from time to time. Most (all?) window managers are not Xinerama-aware, and so some operations like window placement and resizing might not behave in an ideal way. This is an issue that needs to be dealt with in the individual window managers, and isn't specifically an XFree86 problem. ...

In article [EMAIL PROTECTED] you write: Jameson Burt [EMAIL PROTECTED] writes: I seek to use one computer with two full X-windows users. This would be a cheap in time/money approach for my wife and I simultaneously using Linux. It might be worthwhile finding a cheap 386 or 486 with a good graphics card.

You *will* need 2 network cards for this, but setting up two computers on a network under Linux is easier than some single-computer stuff. X is probably too slow over serial. Two HUNDRED meg? I know from experience that all the necessary stuff can be fit on a single 1.44 MB floppy. This included a stripped-down kernel, libc, ash, S3 X server, and the necessary tools to establish a SLIP connection over a null modem cable. Unless you have less than 8Mb of RAM, you probably won't need a swap file/partition. I didn't use init, but wrote a small shell script to do its job instead. If you don't mind a small amount of lag, it even works acceptably fast over a 115.2kbps wire! However, if I was doing this for any other purpose than proof of concept, it would hardly be worth not paying 20 pounds each for a couple of cheap network cards.

Re: two keyboards, two monitors, two users, one processor?
This discussion starts to be out of list's topic, sorry. I'll send further responses only by e-mail. If the power instalation is properly designed, it should be no problem. However I, personally, would always prefere two have an additional zero current ground wire dedicated for computers only. And there still exists a problem with voltages induced by eg. electric storms. The optoisolation circuit (not very expensive, because it is not very fast link, and for software flow control two transoptors powered from unused port lines are sufficient) is much better solution. The standard built-in serial ports, are rather delicate (Usually they are even not compatible with RS232 standard, because they may work correctly with 0V-5V logic levels). The professional RS232 boards should be safer. This problem is particularly serious, when someone wants to connect two computers using their parallel ports (and PLIP). The parallel ports are much less protected.

The safest solution is to power both of them right from the same socket.

two monitors
I am trying to get an old mda (hercules compatible?) card going together with a Matrox Millenium on an ASUS P55T4P2 motherboard. On my quest, I have found two ways to do this, one of which almost works---a multimon kernel patch that has compiled cleanly on 2.0.33. A second approach is called mda and is a module. Neither of them works for me yet. Multimon seems to show the most promise, and apparently is the more flexible approach in all, anyway. I suspect the mono card may not be good: the linux kernel boots with both monitors established by the kernel during the boot process, but I can't get a boot from the mono card, even if I remove the svga card---the bios won't even write the change of monitor type to cmos. I set gettys up on tty9 and tty11 for the mono monitor: when I switch to those vc's, the cursor disappears from the svga monitor; but it never shows up on the mono monitor---that monitor never does a single thing ever. Any suggestions would be appreciated. My experiments are encouraging, at least, so I wanted to mention them with respect to the current thread. The URLs are: multimon for 2.0.32: http://trap.mountain-view.ca.us/~tom/projects mda: http://www.pandh.demon.co.uk A GGI project was mentioned in the mda readme as developing multimonitor configurations: http://synergy.caltech.edu/~ggi The multimon patches look to be compatible with CGA, as well as mono monitors.

two keyboards, two monitors, two users, one processor?
I seek to use one computer with two full X-windows users. This would be a cheap in time/money approach for my wife and I simultaneously using Linux. I believe I could get a dummy terminal working through the serial port, then display on a second monitor (though I don't know any approach for a second mouse). Is this reasonable, or is there another approach? -- Jim Burt, NJ9L, Fairfax, Virginia, USA [EMAIL PROTECTED] http://www.mnsinc.com/jameson [EMAIL PROTECTED] It is not the shortcomings of others, nor what others have done or not done that one should think about, but what one has done or not done oneself. --Dhammapada [dp command for quotes from the Dhammapada, in Linux] -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

It might be worthwhile finding a cheap 386 or 486 with a good graphics card. Install a minimum of programs on it, just the X server. If you run xfs on your main computer, you won't even need the fonts. You could do this with even a 200 MB hard disk, I think. You *will* need 2 network cards for this, but setting up two computers on a network under Linux is easier than some single-computer stuff. X is probably too slow over serial. (Just another option.) It is easy to plug in two mice, dodgy to plug in two monitors, but pretty much impossible to plug in two keyboards at the moment, IMO. -- Carey Evans http://home.clear.net.nz/pages/c.evans/ GNU GPL: The Source will be with you... always. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

A better option would be to look at the dxt package on sunsite- it is a nfsroot linux boot floppy that you can set up to run an X server on- I've hacked it up a bit, so it will use an X font server such- I may release it at some point in time. It is not the best solution, but it is out there. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .
Two-monitors
I have two video cards installed on my machine. I also have 2 monitors I'd like to have running. However I have not yet figured out how to get the system using the second video card. So far the only place I see any trace of the second one is in /proc/pci where it is listed as a PCI device. To possibly make life more difficult, both cards are the same brand - the only difference being the amount of RAM installed on each (4 vs 8MB). Does anyone have such a setup going? I plan to use x2x once I have them both going, but need to get over this slight hurdle first ;-) TIA 8---8 Richard Shepherd ([EMAIL PROTECTED]) 8---8 -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

Re: Two Monitors
(Sorry for the delayed reply; I haven't been reading the Debian lists for a while.) There's a package in hamm called x2x which will take two separate X displays (e.g. :0 and :1) and allow you to move the mouse and keyboard focus between the two. You can either have a button to click which warps the pointer to the other display, or set it up so that pushing the mouse off the edge of one screen makes it reappear on the other. It won't allow you to move windows between displays, and you'll have to run two copies of your window manager, but it seems to work. Unless you have libc6 installed, you'll have to get the source code from hamm and recompile it. I'm afraid I don't have a Debian 1.3 machine left to do this on. -- Charles Briscoe-Smith White pages entry, with PGP key: URL:http://alethea.ukc.ac.uk/wp?95cpb4 PGP public keyprint: 74 68 AB 2E 1C 60 22 94 B8 21 2D 01 DE 66 13 E2 -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

Re: Two Monitors
I read an article in LJ describing the Metro-X server (I think that was it anyway), which can drive multiple video cards (though only with the right cards). I don't know if Xfree has any support for this sort of thing, or exactly how it would shake out with interrupts and such. I too am interested in this. If you find anything else out let me know.
