Linux on Samsung M70 Notebook
 

Hello !
I just got my new Samsung M70 with 19'' Widescreen but I only get it work with vesa driver from Xorg. The M70 has a NVIDIA Go 6600 GPU but neither the nv driver from Xorg nor the nvidia driver works. When I start X with nv or nvidia driver I can't see anything.
I think it has to do with the HorizSync and VertSync values. I can't find any tech data about the LCD. I already called Samsung, but until now no response.

Does anybody have a working xorg.conf with nv or nvidia ?

Thanx !

P.S.: This is my first post, just registerd and hope I took the right Thread ...

Yes Tolot !
Read The README.txt (Chapter 3. Configuring X for the NVIDIA Driver)

If you don't have the nvidia drivers Download from nvidia .

Use xorgconfig as root.

Thanx for the answers! I am a little late, because I was not online. I installed Windows XP (sorry for that ;-) for testing purpose, but later about that point.

For the xorgconfig (as root) you must know the frequencies (that I don't have, or better: I got some parameters by testing with Windows XP) or use the standard vesa modes up to 1280x1024, but that already works, not with nvidia though ...

Also the README.txt from NVIDIA is of no help in this case, because there are no informations about the frequencies. I already tried to find out something with read-edid over ddc, but that doesn't work with the Samsung LCD under Linux. When I found out that I tried to disable ddc, but still no result.

I then decided to install Window XP for testing and wrote down the different frequencies for the differnet resolutions, but that also doesn't work when I modified the xorg.conf. All modes had 60 Hz for vertical sync.

Now I am back on Linux, but Nvidia still doesn't work and vesa only with 1280x1024 instead of 1680x1050 and mplayer with vesa ... no joy !
The thing is, that the xorg-log has no errors ! I just don't see anything, so there must be a problem with the frequencies, I guess.

And by the way the driver for the intel hda also doesn't work right now, there is a weird whistleing on one channel ...

So there is still a lot of work to do for the Samsung M70 (did I mention that the SD card reader also doesn't work right now ?)

But never give up ... there will be a solution. So I still wait for suggestions ... and call Samsung again ...

Thanx, Tolot

For your frequencies look in manual "Samsung M70"

The nvidia driver has installed correctly ?

If this is no .
Then you mast have kernel-source or kernel-headers and reinstall nvidia drivers !

If this is yes ! Then :

Run the xorgconfig or xorgcfg " xorgconfig with gui " (as root) save your changes .

Then edit the /etc/X11/xorg.conf :

Remove the line:

Driver "nv"
(or Driver "vesa")
(or Driver "fbdev")

and replace it with the line:

Driver "nvidia"

Remove the following lines:

Load "dri"
Load "GLCore"

In the "Module" section of the file, add the line (if it does not already
exist):

Load "glx" .


save the file and reboot.

Try and nvidia-settings command .

Maybe fn key to change your output ?

Try and Slackware 10.2 !

I hope that i have helped you !

Thank you IZO 0, but I must have told that I have experience with Linux for over 5 years now. I am responisble for about 10 Linux computers with Linux. Nearly all of them have Nvidia cards, so I am quite experienced with installing nvidia and editing the xorg.conf. Sorry that you had to write so much, but I am sure that the module is installed o.k. I already tried another Monitor where I know the frequencies (also TFT) and it works perfect ... and the manual only tells something about the vesa modes up to 1280 x 1024 and that resolution works, only with the vesa module. it is odd, but it doesn't work with nv or nvidia driver.

I really think the only thing that works are the frequencies for 1680 x 1050 and then maybe there is something to do with the nvidia driver. I will go on trying and report the result, if somebody else needs it ...

But thanx very much for the work and help, that is the spirit of LINUX ;-)

I think it is time to give a little update:

still the lcd only works with vesa driver. But when I detach the LCD and use the external Sub-D 25 socket it works with nvidia driver and the same xorg.conf ! with a resoultion of 1600 x 1200 (4:3) but not with 1680 x 1050 (10:9).

So the next step is to find out why nvidia controls the monitor through the external socket differently then when the lcd is directly connected with the M70. Maybe it's a digital connection ?

I will go to try out different things and will report. Maybe somebody else has experencies with the Samsung M70 ?
