Xorg-Error:No devices detected With installed nVidia driver.

[Chinese]

hello everybody again.

I have ASUS A53XI241SV laptop with core i5 2410M and the Graphics have two.the one is intel's and the other oen is nVidia GT540M.

00:02.0 VGA compatible controller: Intel Corporation Sandy Bridge Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation Device 0df4 (rev a1)

So i'm installed the BT5 KDE 32 on my harddisk with dual boot(windows7 and BT5).Then i'm installed the nVidia driver.but there have a error when i use startx:

To solve this problem((EE) No devices detected.),I had post a Threa for help at here.

At now i'm puting "PCI:1:0:0" into /etc/X11/xorg.conf at the "section Device" line and startx.Now the error "No devices detected" not Appear.but there is new error Appear.

when i startx the screen is Black.but i hear the sound of the startx.

Looke the Xorg.0.log like this:

I had similar issues as you getting my 9800m gts to boot into x after installing drivers (and even before tbh). Have you tried this?

It fixed my problem on my laptop and my desktop.

i have the same problem

have anybody found the solution??

pls help

Why no one Knows how to fix that problem?? Could you guys take a look over here... if you can manage and make it to work reply back please.
I tried to make it but cant even find nvidia-kernel-dkms.. I think this problem happens to us because we have Optimus tech and we firstly need to configure intels VGA ... The same thing happens at windows and you need firstly to install VGA drivers then the Nvidia's drivers. I hope im helping you in order to fix this out.

One reason for nobody being able to solve your problem is they may not have your exact hardware.
There is soo many varieties of OS's and hardware today--we are blessed! But the number of answers for your specific hardware/software choices goes down as the type of computers goes up.

You might want to read the documentation for both the card and for xwindows itself.

Both have good sections on troubleshooting. They even list some causes for the exact error you are having.

The read-me file for drivers 290.10 on nvidia's website, has detailed information about several common errors and what to do about them. Chapter 9. of that document is "Known issues" for one place to look, but there are several sections that help with troubleshooting an install of an nvidia card in Linux.

One thing I learned from the nvidia documentation is how to get more information from the nvidia driver to do troubleshooting. There are 6 levels of "verbose" which each give more info about the driver and what it is doing/finding. It is a command line option for startx, even though I found it in nvidia's file:
startx -- -verbose 5 -logverbose 5

It will show you things like that you are still using a driver from xorg instead of the new one from nvidia corp.--which it lists as a common problem in the troubleshooting section; leftover libs from original or previous installs of video drivers.

I wish you success in finding the answer for your chosen hardware, and hope you can channel your anger at other people not solving your problem into determination to finding the answer yourself and post it for others.

Look for the read.me for the driver version you are using, 290.10 I think is current driver.
One link: http://www.nvnews.net/vbulletin/show....php?p=2503979 then click on the "readme (x86/x86_64)" link
to read the file for your cpu type (32 or 64 bit).

You might also learn from the documentation about Xwindows--there are reams of pages about installing and configuring. Take a look.

not sure if this helps but i had the same issue because i added some script to the Xorg.conf file i just deleted the file and it fixed it but in your case you could try to modify the added code that is including the drivers perameters and it should start then. goodluck
