Fedora Hardware :: Monitor / Graphics Card Not Detected - Recognized To Work In Full Resolution
Oct 11, 2010
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 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.
Tried to run nvidia driver installer:

Today my desktop reverted to 1024x768 resolution immediately after init. I tried changing it back but only 1024x768 and 800x600 are listed as supported in the display settings, even though my monitor supports resolutions of up to 1360x768. Rebooting the system did not solve the problem.I'm running Fedora 15 x86_64 on kernel 2.6.38.8-35 with the proprietary nvidia drivers of version 275.09.07. My monitor is a Samsung SyncMaster 933n. nvidia-settings is apparently not detecting it correctly, it thinks I'm using a CRT monitor.I was actually in this exact same situation a few months back, but it kind of went away on its own, so I didn't mind too much. So, what could be causing this, and what can I do?

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.

OS: Fedora 12
Video card: ATI Radeon 9200 series
Monitor: ViewSonic 19"
I installed Fedora 12 configured Gnome automatically. Generally default settings. My monitor was connected directly to the video card and all was good. My video card was detected and my monitor was detected as ViewSonic Corporation 19" and I can set the screen resolution to 1280x1024. I had no xorg.conf file, as it seems that Fedora 12 does a great job of PnP to just set everything up.Now I go and complicate things by hooking up my monitor through a KVM switch. All of a sudden my monitor is "Unknown" and the best resolution I can achieve is 800x600.
Sure, I could go and reconnect without the KVM, but I want to be able use it.Is it possible to edit xorg.conf to tell it "Trust me, just use 1280x1024 at 60Hz even though you can't figure out what the monitor is"?
I tried a number of the posted suggestions to generate xorg.conf files but none of them get me what I need. A simple sample file listing that does the minimum is greatly appreciated (I can experiment from there once I get a basic setup working).And can someone explain if it is X or the ATI driver that is getting confused by the unknown monitor type. It helps to know what is actually going on in addition to a fix (so I can figure it out myself in the future). Thanks!

After install F12 on a clean install, I can't change the display resolution, my graphics card is a Intel 82945G/GZ, my monitor is a LCD 32" TV
I follow this steps:

Then I edit the xorg.conf file with this code:

But nothing, I still get the 800x600 resolution and I can't change it.
Is this a driver bug?

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 have a Mini-ITX VIA EPIA LT series motherboard running Slackware 13.1
Graphics card is not recognized properly.
But the graphics is OK the first half of the boot, then it turns weird and stays that way.
The screen is very dark, tux in the upperhand left corner is colored wrong. (Red, Purple, Green)
I did a Xorg -configure, and this is the content of xorg.conf.new:
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code]....

Got a system that I've been using for a long time now without any problems. Now suddenly it won't use a higher resolution than 1024x768.I never added any mods to the configuration and have not added any software other than recommended updates it quite a while.Any ideas what happened or how to fix it? I checked and the monitor/graphics card will still do upper resolutions with windoze so I'm guessing the hardware is alright.Using OpenSuse 11.3, 64bit, on a dual core athalon with a Sapphire ATI x1600 graphics card and a 22 inch flat screen that is supposed to go 1600 x 1050.

I have problem with resolution (@gnom desktop). In Yast --> videocard & monitor is all right. There is correct resolution 1366x768 (WXGA). Also the videocard ( I don't have really one, only chipset "Intel Mobile GM45" ) is correct recognized. But Monitor isn't recognized, and I don't know which one I have (It's notebook from acer).
Nevertheless if I go direct in monitor preferences (at the bottom the monitor with a ruler symbol) the resolution is set to 800x600 and I can only change to 640x480. The monitor is as 15" recognized (I have 15.4", even a bit more broadly - 1366x768) and now I don't know what to do. All symbols, all programs, everything is huge! How is it possible to configure the correct one resolution?

I have two video outs on my AGP video card. One is VGA and the other is S-video. I tried connecting the second monitor (Viewsonic) by itself to the VGA port and it works fine and runs at 1280x768 very clearly. I then attached the LG monitor instead to the VGA and attached the Viewsonic to the S-video port. Now it is running at 1024x768 and I have no option to increase the resolution.Is this a limitation based on S-video being worse than component, which is worse than VGA and it simply cannot handle the data density for larger resolutions? Or would it be my video adapter? I swear I had monitor control working fine through the panel, but now when I click on the monitor button it says, "It appears that your graphics driver does not support the necessary extensions to use this tool. Do you want to use your graphics driver vendor's tool instead?" and that opens an Nvidia X control panel.
Also, using S-video means the computer doesn't recognize the Viewsonic LCD TV properly, it just recognizes it as a TV. Is this because S-video doesn't play nicely with EDID reporting?It would be nice to get a sharp picture on that TV, the way I had when it was connected like a monitor via VGA. I am not sure what's going on anymore, so any help on clearing up driver issues or getting configuration apps installed or anything like that would be helpful.

Ubuntu is not the problem; I don't think. I'm running Maverick 10.10. With my computer I have to unplug and plug back in the graphics card every time I want to start up the computer so I usually keep it running 24-7. There was a power surge and when I got it back running, once it reached the load boot screen and it was stuck their for awhile. Then it instantly sent me to x-term. So I tried logging in and typing:
sudo start gdm
It said it was already running but I could not display anything or login the normal way. I restarted and the same thing happened. I managed to get to Recovery Mode and I fixed broken packages and then I ran it in low graphics mode. It said that the display, monitors, input, and graphics card could not be detected. If there was a way to resize the screen to something more tolerably than 800x600 in low graphics mode I'd be glad to hear it. I could at least stick around to using that until I can fix some stuff up.

I got Linux Ubuntu because my Vista installation messed up, and I couldnt find the recovery CD. Im pretty glad I installed Linux, as it seems really freidnly, and a bit more open that Windows, I must admit. The problem is, I am trying to install my Nvidia GeForce 8600GTS on the system, and it isnt working. It was working fine on Vista before, so it shouldnt be a hardware problem. I have followed various instructions on websites, whioch take me throguh some stuff about stopping GNOME, removing * linux restricted module * and so on. But when I get to the crucial point, with the agreements and installations for Nvidia, it tells me it cant detect any graphics cards.

After a while I decided to give ubuntu another go so I set up a dual boot configuration. Everything works well except my graphics card. I have 2 problems (don't know if they are connected)To start with, it's a laptop with an onboard Radion 3200 and it has another ATI Mobility Radeon HD4570 built in. I have an external screen attached to my laptop. (1920x1080)When Ubuntu first booted it asked me if I wanted to install proprietary drivers, so I did that. Now when I took a look in the control center it showed my two monitors but they were both attached to the 3200 and I can't seem to find anything about the other (better) card. It does not appear in the proprietary drivers, I can't (I think) select it in the configuration utility.

I have three monitors. Two are hooked up to an ATI card and the third to an nVidia 6800 card. This third monitor is not being recognized. I tried installing nVidia's official Linux drivers but received an error that no compatible device is present. Going into System > Preferences > Display shows only my first two monitors. I'm running Ubuntu 9.10 x64.

I'm looking for advice on which is the best video card to get for Ubuntu 11.4. At the moment I have an INTEL SERIES 4 INTEGRATED GRAPHICS CONTROLLER and I can only get it recognized as a "VGA COMPATIBLE" Due to my eyesight I need to have the resolution smaller something like 1168 x 752 I dont need to be be able to play games or anything like that. Just typing, videos and general PC work. OR if anyone could point me in the direction of installing better drivers for my INTEL card as I know Windows XP can give me resolutions of this depth.

I'm running hardware already considered legacy and I was made painfully aware that those drivers, for ATI cards, are only available from Jessie repositories; yet, somehow I was able to have my system configured to run not the stock drivers the system used for installation but, allegedly, proprietary drivers.
I did notice an overall improvement on how the system displays everything on the screen but after fumbling around the system trying to install a game I had a message warning that only software acceleration was activated and not full hardware acceleration, which was what I was aiming at.
After going through a lot of guides on the web I was able to:
a) discover the system is running MESA drivers (or so I have understood)
b) install headers for my system but somehow along the way I fumbled whatever I was doing and I probably now have a lot of loose ends in the system
Being Debian (and rock solid) the system is still running smoothly but I really want to clean up after myself and correct what I can and improve where is possible.

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.

I've been trying a bunch of different solutions to getthis fixed. Let me give you the details: I'm currently on Ubuntu 10.04 Lucid Lynx. I have a Geforce FX 5200 graphics card and I have the nvidia proprietary drivers installed (version 96, I tried 173 as well but there's doesn't seem to be a difference).
My monitors native resolution is 1680x1050 but since my graphics card cannot handle that resolution I use 1280x1024. I've had this resolution working before on Ubuntu as well as Windows with the same graphics card. My problem is that in nvidia-control, the list of resolutions does not include 1280x1024, and the closest to that is 1280x900 which is not supported by my monitor. So the only tolerable resolution I can get is 1024x768.. if you've used this resolution then you know that it is not tolerable for long. So I tried to force the resolution by using xorg.conf.. Here it is:
[Code]...
For some reason this isn't forcing 1280x1024.. I'm still in 1024x768 and it still doesn't list it in nvidia-control.. What's weird is that on the previous release (Jaunty or Hardy) this xorg.conf worked fined and got me my 1280x1024.

Just tried and failed miserably to get an Nvidia 6200 based graphics card to play nice with my machine.After putting my ATI Radeon 9200 back in the box, my emulators have gone all kinds of strange.
ZSNES will crash as soon as I attempt to load a game full screen and will leave the screen resolution at the resolution ZSNES was running in (800 x 600, for example.GENS again will alter the screen resolution to whatever it was running in when the emulator is minimised. I'm running 10.10 with 1gb Ram, 128mb ATI Radeon card, P4 3ghz. Was all fine until I tried the new card and I did a fresh install only last week .

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

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.

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.

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?
