Hardware :: Screen/Monitor Cannot Be Found Despite The Graphics Card Has Been?
Apr 26, 2010
I'm using an Intel Q45 graphic card, VGA and HDMI. I have two monitors and both work with Win7, splitting nicely. However in Suse it doesn't find the second monitor, the one on the HDMI port. However Suse does find that there is a HDMI port it could use. It's just not set up to have a screen attached to it.Xinerama won't work. I tried it despite the fact that it shouldn't I have tried numerous xorg.conf setting according to a number of sites that were very helpful and very thorough. I tried to modify their advice but it simply didn't work out for me.It seems like the screen is simply not acknowledged within the system for some reason. I'm running OpenSUSE 11.2 with KDE4.4, factory and my other systems pick up the screen without a hitch. My home system did the same with a HDMI connection so if anyone can point me in the right direction or even better

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.

the only way to get multiple monitors AND compositing (Compiz) on Linux is to use a single graphics card that can drive both (or in my case all three) screens. I bought a Radeon 5750 specifically because it claims to able to drive 3 monitors. I can plug in 3 monitors (2 DVI, 1 HDMI) and the Catalyst Control Center shows all 3, but only 2 can be enabled at a time.
The exact message is:
The current settings cannot be applied. Possible issues may include:
- Display(s) cannot be enabled.
- Setting(s) cannot be applied due to insufficient video memory.
So I'm going to assume that either the 5750 doesn't support 3 monitors, OR, more likely, ATI couldn't be bothered to add that support to their Linux drivers. So this is a multipart question:
First, can anyone suggest a PCI Express Graphics card that can run 3 screens on linux without tremendous pain? I'm looking for something where you install the driver and all three screens "just work". Does such a card exist? Second, if you have a 5750, have you been able to get it to do 3 monitors? I'm running Ubuntu 10.04 at the moment. UPDATE: I got my active adapter in the mail today (it's DisplayPort to DVI) and so far things seem to be better. I can run my third screen, drag things seamlessly between them, and I am also running compiz. The adapter I'm using is a "B087B-005B" made by "Accell", UPC is "826388106239".
There's still a couple "annoyances" that need worked out though: The left most screen is always the primary monitor. Which means the "gnome bar" (is that what you call the applications-places-system menu?) is always on the left most screen. It also means that new dialogue boxes always opened centred on the left screen, which is counter intuitive. Especially if you're using a program like GIMP and the text editor or color picker pops up on the left. Does anyone know of a way to change it so that new windows always pop up on the center screen?

i have a fairly outmoded system:
mb gigabyte ga--m57sli-s4
cpu athlon 3800
memory corsair ddr2 xms 2gb
graphics nvidia gforce 8500gt
hdd western digital 400gb sata
monitor hp lcd hp1740
the screen plays up sometimes. it gets a yellow line down one side. it's the office type 4:3 aspect monitor which seem to be getting rarer. if i switch to a widescreen 16:9 format, would i need a new graphics card?
i don't play games. but sometimes there'll be stuttering when i'm watching a videos video. whether this is the screen or something else i don't 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.

the solution of my monitor is much to small. So I tried to find out, where I can change the settings of my graphic card and monitor. Unfortunately opensuse only gives me the possibility to change it up to 600x800, which is by far too small. So I thought maybe I need to install a driver... so... there I am ... having question marks around my head and wondering how to install a graphics card driver on my opensuse 11.3.???
And where to find the right ones?
My graphic card is a Matrox Mystique (no 220 or anything else!!). I checked the website of Matrix to find my drivers, but it tells me that there is no driver planned for linux. Matrox Graphics - Support - Latest Matrox drivers for legacy products But I guess I am not the only person in the world who uses this graphic card on linux, so there must be a way to make it work!!

I'm planning my next desktop build (currently only have a laptop that is falling apart), and one of the features I'm really looking forward to is multiple monitors. I'm thinking a 1920x1200 center monitor and two 1600x1200 on either side, but I'm not decided just yet. I don't know if I really need that resolution.
I have a few specific questions though. The only time I've ever messed with multiple monitors is way back when I had Windows, so I'm not sure what to expect on Ubuntu.
1: What is the best Graphics card brand/series to use? I've seen that ATI has more powerful hardware than nVidia for the same price range, but nVidia seems to support Linux better. I'm using an ATI card in my laptop now and have never had any problems with it (with either open source or proprietary drives, other than open source drivers didn't do well with 3d). I would also like these GPUs to be running F@H while I'm away, so GFLOPS is just important as gaming performance.
2: Since I want to use 3 monitors, I assume I should get 3 of the same graphics card or a card with 3 identical outputs (do those exist?).
Or can this be done some other way. For example, a more powerful card for the center monitor, and less powerful cards for the other two. Do those need to be the same brand, or could I use, for example, ATI and nVidia cards on the same desktop simultaneously?
3: Is it possible to have a virtual console on one monitor with a desktop on the other two, or do I need to set up a terminal on the desktop to use that monitor?
4: How can I run fullscreen SDL games with multiple monitors? Will it only show on one screen or stretch across them all? Is it possible to have a fullscreen game running on one monitor with the desktop visible on the others? How would the mouse focus work with that? Or does it just all depend on how I setup the monitors?

I know there are many threads on similar issues but I can't find anything that will work. Not sure if I need drivers or what to do - I feel really stupid as I should be able to get this right but I am at a brick wall. Basically I have a 20inch monitor hooked up to the on-board graphics card and cannot get higher resolution than 900 x 600. It should be at 1280 by 1240. This is a brand new install with the latest Ubuntu 10. Under monitor preferences its says 'unknown' for monitor type and I don't have any driver disk for this screen but never needed one previously.

I actually do have a GeForce4 MX 460 in this pc. I have a 7950gt in a different pc. Oops. I guess the MX 460 cant do 1600x1200 on the dvi output but somehow it can do it on the vga output? I guess I could just use a vga connection instead of the dvi connection.
The problem I'm having is that my LCD monitor (acer AL2021) can't be used at it's native resolution of 1600x1200. This is probably because my GeForce 7950gt graphics card is not being recognized. Xorg seems to think my card is a GeForce4 M 460. (It's not, really!) I'm using Ubuntu 10.04 LTS.
Here's what I've been doing for the last few hours:
This didn't work. 1600x1200 is still not listed.

I have a Dell Vostro 3300, i5 460 processor with a NVIDIA 310M Graphics Card. I'm doing a KUBUNTU 10.10 (Maverick) install with the following results. The Live CD boots just fine to, "TEST," or "Install." Installation goes fine. However, the graphics card being used is the Intel i915. I have tried installing the NVIDIA drivers directly from the, "Additional Drivers," tool and after the reboot I get through the boot screen to the console. I try to manually startx and I get the errors, "no device found," "no screens found." The second install I tried purging and blacklisting the nouveau drivers and entering safe mode. Then using apt-get install nvidia-current. After that, nvidia-xconfig. Same results.
The third attempt I re-installed and this time downloaded the drivers from the Nvidia site (version 256.53). Blacklisted nouveau, remove all nvidia, updated initramfs, etc. The install went fine however I still end up at a console after boot with the same messages as above. No device found, no screens found. I've tried searching through the forum and web and have tried things like adding the modset option along with many other hacks, tips and fixes. still, no go.I can live with the Intel graphics for now although I lose 512MB of memory. Unfortunately there is no way to disable or change this set-up in the BIOS. I've seen quite a few bug reports at Launchpad:
1. Is this something I should just wait til a fix comes? Will a fix come?
2. Is there, or will there be an official Updated Ubuntu Guide for Maverick to install NVIDIA drivers with this tecnology?
3. Lastly, is there anything else I should try??

I installed a new copy of F13 this morning on my fairly new laptop.32 Bit Intel, 3GB Memory 120GB HDD. The problem I've got is that my Monitor/Graphics card is not getting detected and as a result I'm getting a horrible Resolution/Refresh rate. When I run
lspci | grep VGA
I get this 01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 771/671 PCIE VGA Display Adapter (rev 10). how I can get my monitor/graphics recognized to work in the Full Resolution.

I've just installed ubuntu 10.10 on my desktop system. it worked fine with my 5770 but when using my gtx 460 it has a crashing problem. After roughly 30 secs running the screen has a red cast and a grid pattern to the bottom right of the mouse. Need directions to solve this such as new drivers or an exact sequence etc as i've only got 30 secs to completee process before it freezes. Specific graphics card is a gainward gtx 460 GLH too btw

I'm running Ubuntu 10.10 on what used to be a windows vista. I bought me a new graphics card today so that I could run dual screen (GeForce210). I saw a guide at [URL] and I followed it.
I typed: sudo apt-get install nvidia-current
then I restarted my computer, once again as instructed I typed:
sudo nvidia-xconfig then logged out as instructed...
After I logged out the screen went black and I was not able to login. So I restarted my computer. Now when I turn on my computer I am getting this error and it's stopping at it.
fsck from util-linux-n/g 2.17.2
/dev/sda1: clean, 255658/294092280 files, 5031534/117616640 blocks

Starting GNUstep distributed object mapper: start-stop-daemon: unable to stat /usr/bin/gdomap/ (no such file or directory)
speech-dispatcher disabled: edit /etc/default/speech-dispatcher
*starting the winbind daemon winbind
It stops on this screen. I do not want to wipe it but I cannot get it started. I do have an external hard drive and at the moment I am using my Ubuntu disc to "try Ubuntu" I was going to try backing up everything I have but it will not let me access root because I am not logged on to that user, is there anything I can do to get pass this? I've called around and no one is willing to work on my computer since it is now running on Ubuntu 10.10

Just fitted an Inno3D (I-7300LE-G4E3) graphics card and I get a distorted boot up screen, a virtually unreadble boot menu (lots of extra white bits all over the screen) and when the system is booting the black screen with "booting from .." and the underscore at the end, is covered with white commas (?!), then the login screen pops up for a fraction of a second, then get a blank screen and no signal-cant get anything after this (or from the vga port on the pc)-I ve tried logging in even though I cant see anything, but no music , nothing.
Thought I might have to download drievers AFTER I d installed it, but as I had this problem, I removed it and tried to download driers before installation. Not sure which of the 4 to try, but tried 2 and neither works-GDebi is offered as an app to open them but nothing happens, nothing happens if I just click on them and when I try and install them from a terminal with the script from the nVidia site, it says unable to open them.

I've been using ubuntu on a new desktop for a couple of months, but i had an old HP that was given to me in my basement. It has 384Mb of ram, and thats because i had a 256Mb stick laying around. I installed debian becuase it is more suited for older hardware (at least from what I've read). It installed fine, but it boots to a blank screen, and pressing ctrl+alt+F2 bring me to the command line. I checked /etc/X11/xorg.conf to change the driver to vesa, to find out my video card isn't even shown. I ran lspci and I found that it says my graphics card is Intel Corporation 82810E DC-133 (CGC) Chipset graphics controller (rev3) In the device section of xorg.conf, it merly says Identifier"Configured Video Device"

I'm using a Gateway LT3103u running a dual boot of Win 7 and Ubuntu 10.10 (separate partitions) and ever since I've started using Ubuntu (last October) I've had persistent graphic card problems.
My graphics card is the ATI Radeon X1270.
Right now I can't use any visual effects because of I do the screen spazzes out and becomes unusable. This isn't a big deal for me since I don't use them but I figured it's relevant to the problem.
Even with visual effects off I still have problems and at times parts of the menu will stay on the screen in a little box which covers any windows that open beneath it. The only way to get rid of it is to turn visual effects on so the screen resets then hit use previous settings.

I have a Gigabyte GA-MA74GM-S2 motherboard with integrated graphics that shows up on lspci as an ATI Radeon 2100. I also bought a PCI-Express Nvidia graphics card so I could use the VDPAU feature on Linux (plays H.264 in hardware). The BIOS has three settings about which display to initialize first:
Integrated graphics
PCI graphics
PCI-Express graphics (PEG)
I set the BIOS on PEG, but
I cannot get anything, not even a splash screen or POST messages, to emerge from the PCI-Express graphics card. (I'm using a DVI connector; the card also has an HDMI output.)I cannot get the kernel lspci to see the graphics card; the only VGA controller it acknowledges is the integrated one.Running dmidecode acknowledges the existence of an x16 PCI Express slot, and it says
Current usage: Unknown
There is an additional BIOS setting called "Internal Graphics Mode" which is normally set to "Auto" which means it is supposed to prefer a PCI Express VGA card. I set it to "Disabled" which now means I'm getting no output at all. I will soon be learning how to do a BIOS reset!
Other information: The PCI-E card is a MSI N210-MD512H GeForce 210. This is a fanless card. Although there are no fans to see turning, the heat sink on the PCI-E card is definitely getting hot, so the card is getting some sort of power.It gets all its power from the PCI-E slot; there is no external power connector.The BIOS is an AMI Award BIOS.how can I make the PCI Express graphics card visible to Ubuntu?

I'm playing with dual monitors. I have an NVIDIA GT220 set up so that my monitor and my TV are running as extended desktops. Everything is working well enough, but there is one annoying bit I've noticed:
If I'm watching ..... on monitor 1 in fullscreen and working on monitor 2, clicking anything in monitor 2 kills full-screen in monitor 1. Is this something that can be fixed somehow or is it a hardwired "feature"?

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
