1. What video card are you using?

/sbin/lspci -v |grep VGA

I have the same issue. But its kinda a "no issue" thing. I just choose the resolution that I want and (1024x768) and Im happy. I wouldnt worry about the "undetected monitor".

Just make sure you are running the correct driver for your video card to get the resolutions you want / can support.

Hi have the same problem with FC12
I have a monitor Acer AL1714 and the display is only 800 x 600
What can I do?

/sbin/lspci -v |grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller])

Could you post your /etc/X11/xorg.conf file? I have seen posts that sometimes the video card does not read the monitor settings correctly and will fall back to 800x600 resolution.

I also ran across this:

Open a term window and issue the command:

/usr/bin/xrandr

Paste the output so I can see it.

A Quick google check shows this as a working mode line you might need in the xorg.conf specifically in the "Section Screen" area.

Modes "1280x768" "1024x768" "800x600" "640x480"

For your reference here is the link to the posting about your video card and someone that had the same type of problem and how they solved it.

Hope this helps,

Hi,
this is the output from

Code:

/sbin/lspci -v |grep VGA

01:00.0 VGA compatible controller: nVidia Corporation G72 [GeForce 7300 SE] (rev a1) (prog-if 00 [VGA controller])
the resolution of my display is ok 1280x1024, but it's the refresh rate that I'm concerned about: only 50Hz.
Isn't harmful for eyes ?

Do your eyes hurt or have you noticed any tendencies like unusual hair growth or abnormal skin color? - just kidding here.

In your menus see if you have the nvidia config utility installed. Look in applications/system tools / nvidia display properties. See if you can change it there.

Make sure your nvidia driver for that card is running. I think with the age of that card you are going to be using something other than kmod-nvidia. Most likely a legacy driver. Check with mjmwired below:

fairmonk · #9 9th February 2010, 12:31 PM

yes, I found that there is an option from that NVIDIA control panel (some MetaMode ) which allows me to set resolution and refresh rate. I managed to set it to 75 Hz.
Thank you again.

im having the same issue on a HP Pavilion Laptop - that has a
ATI MOBILITY RADEON 4X AGP and 3D architecture

the output from /sbin/lspci -v|grep VGA

VGA Compatible controller: ATI Technologies Inc Radeon IGP 330M/340M/350M(prog -if 00 [vga controller])

the /usr/bin/xrandr output is -
Screen 0: minimum 640x480, curent 800x600, maximum 800x600
defulty connected 800x600+0+0 0mm x 0mm
800x600 61.0*
640x480 60.0

so - how do I configure it to 1024x768 (not quite sure on the frequency)

thanks for the help.

Problems with resolution settings generally are a problem with loaded drivers.

Checking which driver is load on your system

lsmod

look for a video driver name.

Check the boot log to see if there is any problems /var/log/boot.log

cat /var/log/boot.log

The most important file to check is the Xorg.0.log it generally gives good clues about what is going wrong.

cat /var/log/Xorg.0.log

jason_tilley · #12 3rd March 2010, 09:10 PM

well - for the lsmod - lots of stuff... but from what I can tell pertains to video -

Video 19088 0
output 2468 1 video
Radeon 448688 0

boot.log -not seeing anything that relates to video

xorg.0.log - lots of info -not sure how to post it here.... but the stuff that stands out is -

No device specified for screen "default screen section"

and

no monitor specified for screen "default screen section"

Drop on down to where it says Section "Device"

Where it says Driver "intel" change intel to fbdev

put your curser right behind the 24
click enter
type modes '1280x1024" "1024x768" "800x600" "640x480"
click enter

I do this all in mc (midnight commander) which has a built in editor that is real easy to use.
also you need to be in sudo mode (ie sudo mc /etc/X11/)

This works real nice if your drivers for your video card are no longer available. I have one computer that has an ATI RagePro 128 card in it. No drivers. This was how I was able to use it with Fedora. I run Fedora 12 on that machine with no problems. (other than what I create myself by changing settings and stuff, Just can't leave well enough alone!)

BugRocks1 · #14 3rd March 2010, 11:18 PM

The Radeon driver is not being loaded the zero there is telling that it is not being used by any service or device.

That is why you don't get higher resolutions.

Solutions I can think of:

- Change the driver to VESA or something else(the open drivers) it should work as a work around but you won't get any 3D acceletarion with VESA which you can confirm typing "glxinfo | grep -i rendering"

ps: First you should see if the VESA driver is load with "lsmod | grep -i vesa", if it shows nothing it is not loaded so you should try that the which driver is being used with "lspci -k | grep -i radeon", the lspci also will give you all the other drivers that are installed and you can use for the radeon card.

- Try and find out if the Radeon driver you are using is the one for your Radeon IGP 330M/340/, if you are lucky is just the wrong driver and you just need to install one that works if it is not that, be prepared to endure a lot of pain probably.

You may see what it is happening using "cat /var/log/Xorg.0.log | grep -i radeon" (maybe not sure) also there may be errors with the flag (EE) so if you do "cat /var/log/Xorg.0.log | grep -i $EE$" you should get all the errors and also there are warnings and notices.

here are the markers the Xorg.0.log uses

Markers: (--) probed, (**) from config file, (==) default setting,
(++) from command line, (!!) notice, (II) informational,
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.

I can't really help you with the Radeon thing as I don't use that but I can point you to some places where there may be some answers.

http://ati.amd.com/products/catalyst/linux.html
http://gofedora.com/fedora-12-ati-catalyst-drivers/
http://gofedora.com/how-to-install-a...ers-fedora-11/

The R100 series includes the IGP 340M if your card is that one you should use the open source drivers.
http://en.wikipedia.org/wiki/Radeon_R100

To try and get the exact model you could try "lsmod -vv | grep -i radeon" or "lspci -k | grep -i radeon"

which should give you something like this:

Subsystem: nVidia Corporation Device 0545
Kernel driver in use: nvidia
Kernel modules: nvidia, nouveau, nvidiafb

If everything else fails go to the here:
https://bugzilla.redhat.com/

And under X-Server file a bug report.

This is what my ATI Radeon 9000 xorg.conf looks like:

Does this help?
