I used to run an NVIDIA GPU onboard the MB, but have transferred the disk to another computer with a stand-alone ATI Radeon HD5670 video card. I have specified "radeon" in the device section of xorg.conf and have specified "Monitor0" in the "Monitor" section as follows:

Section "Device"
### Available Driver options are:-
### Values: <i>: integer, <f>: float, <bool>: True"/"False",
### <string>: "String", <freq>: "<f> Hz/kHz/MHz",
### <percent>: "<f>%"
### [arg]: arg optional
Identifier "Card0"
Driver "radeon"
BusID "PCI:1:0:0"

Section "Monitor"
#DisplaySize 700 390 # mm
Identifier "Monitor0"
VendorName "SAM"
ModelName "SAMSUNG"
HorizSync 15.0 - 81.0
VertRefresh 24.0 - 75.0

The Monitor is a Samsung 32" Smart TV model 5205 connected via HDMI. The xorg.conf was generated automatically with X -configure. When I first tried 'startx', I got a blank screen and, after some digging, found that the monitor may not be recognized because EDID information was not present. I created an edid.bin file and added the following to the "Device" section:

Option "ConnectedMonitor" "DFP-0"
Option "CustomEDID" "DFP-0:/etc/X11/edid.bin"
Option "IgnoreEDID" "false"
Option "UseEDID" "true"

This did not work and I suspect the "DPF-0" is possibly incorrect as the instructions recommending this fix were from ubuntu. On my machine, /sys/class/drm/card0-HDMI-A-1/edid.

I tried substituting "card0-HDMI-A-1" in the "Monitor" and "Device" sections both with and without the additional EDID options above. This did not work; Still "No monitor specified for screen "Screen0"

I have even tried 'startx' without a configuration file with the same result. The "Screen" section is as follows:

Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Viewport 0 0
Depth 1
EndSubSection
SubSection "Display"

I may have two problems:

1. The NVIDIA driver may be interfering with the loading of the RADEON driver.
2. The monitor with the HDMI connection is somehow not being recognized.

Can anyone suggest a solution?

If you're using the nvidia proprietary driver, you may have better luck generating an xorg.conf with

Code:

nvidia-xconfig

Have you tried this?

Edit; I think i mis-read your problem.

I would recommend uninstalling the nvidia driver if you no longer plan to use a nvidia gpu. You could also blacklist it to stop it from loading;
/etc/modprobe.d/blacklist-nvidia.conf

OK, blacklisted nvidia module as suggested, ran 'startx' and got the identical response as
above; the xorg.0.log files are identical. I did start X w/o an xorg.conf file.

The following appeared in syslog:

Jul 2 12:21:53 kernel: [ 197.000746] nvidia: module license 'NVIDIA' taints kernel.
Jul 2 12:21:53 kernel: [ 197.000750] Disabling lock debugging due to kernel taint
Jul 2 12:21:53 kernel: [ 197.094160] nvidia: Unknown parameter `modeset'

Jul 2 12:26:24 kernel: [ 468.659919] nvidia: Unknown parameter `modeset'

Presumably, the modules xorg is loading are the ones in /usr/lib64/xorg/modules/drivers
and are not kernel modules. I am running the huge-2.6.38.4 kernel which does not require
kernel modules at least on boot. Unless the two are somehow linked, I don't see a problem
there.

xorg still cannot find a screen. I'm not sure where to go from here!

One thing i can think of, is that when you install the nvidia proprietary driver, it overwrites important files such as libGL.so. What you should do after uninstalling the nvidia driver, is to reinstall the mesa package, also mesa-compat32 if you are using multilib.

If you haven't already, try that. Also if you've uninstalled the nvidia driver you won't need the blacklist file.

I removed the NVIDIA driver and the kernel driver packages with pkgtool.
I started x, and it blossomed into my KDE environment. I had an xorg.conf
file which included the four entries related to the EDID:
{code]
Option "ConnectedMonitor" "DFP-0"
Option "CustomEDID" "DFP-0:/etc/X11/edid.bin"
Option "IgnoreEDID" "false"
Option "UseEDID" "true"
[/code]

According to dmesg, DFP-0 should be DFP2 on my machine. I thought I would test
whether these entries were needed, and was surprised to find that xorg.conf was
erased. Started X again which worked fine. Guess a conf file is not required as
has been suggested in the newer versions of xorg.
