TFT turns black after startx, nothing happens (MDK90)

[Jarmo Blomster]

Hi all,

I've get no success after two days hard trying, so does anybody have a glue
what should I try next.
When I startx the display only turns black and only softly flashes two times
then nothing happens.
If I try to see the monitors On Screen Display it shows that it is in
800x600 60Hz (+,+) mode.

My Monitor is AG Neovo F-17 (17" TFT LCD display) It is specified like this:
Max resolution SXGA 1280x1024
Display Color 16.7M
Frequency: Horiz: 30-80kHz
Freq. Vert: 50-75Hz
Max Pixel Clock 135MHz
My Graphics card is NVIDIA GeForce4 128M 440 AXP 8x (as you can see in the
log I enclosed)

I attached Config and log files.

Well, try to downgrade the driver version! In my case only the 2960-drivers worked.

Greetings,
Oli.

Can't downgrade because my Linux is Mandrake 9.0.
There is drivers only for 8.2.

Try setting you vertical refresh rate to 60Hz in your XF86Config file.

Some TFT monitors have problems with the vertical refresh when it's set too high.

IE. Remove this line:

VertRefresh 50-75

And replace it with:

VertRefresh 60

There is drivers only for 8.2. Then install it from source. Source works with any distro.

You need kernel-source installed first, though, along with gcc and make (and probably others).

OK, I downloaded and installed the 3123 packages.
Now it seems that the /dev/nvidia([0-3]|ctl) files is missing.
I tried to run the makedevices.sh but it does not help any.
Is there a way to create these dev files?

"but it does not help any"

Well, you run Mandrake 9, which means you use devfs. Which means that makedevices isn't going to create anything; you have to actually load the kernel module to see the devices. Try a modprobe NVdriver and see if they show up.

I finally got it working (well at least I got the KDE up).
I manually removed all the 4191 stuff (by the NVIDIA-LINUX-README) and reinstalled the 3123 release from the tar file, then suddenly - it worked.
The mouse freezes after few minutes mut I think it is annother matter.

Thank's to all who helped me.
