Toshiba LCD issue

[mgrenier]

Could any of you guys help me?

I have a toshiba Satellite 1415 with a nVidia GeForce4 420 video card. Thanks to this forum I was able to install the nVidia linux drives.

My problem is that I'm only able to get
800x600 resolution. Whenever I try 1024x768 I get errors.

I think the problem is in the monitor section's HorizSync and VertRefresh settings.

I've also set UseEdidFreqs to true.

I have no clue as to what to set HoriZSync and VertRefresh to. And from everything I've read It can be dangerous to play with these values.

Try these settings (in /etc/X11/XF86Config-4):

HorizSync 31.5-100
VertRefresh 50-100
Modeline "1024x768" 110.16 1024 1056 1168 1360 768 772 776 810
Option "ddc" "off"

Also, in the "Screen" section, add:
Modes "1024x768"
Virtual 1024 768

I do not promise it will work on your machine (mine is a Tosh SatPro 6100) but it's worth a try.

If you get a white screen or sync loss kill the X-server immediately (Ctrl-Alt-BkSp) and revert to your old XF86Config-4 file.

Let me know how you get on!

Thanks,

This is what I did, and seems to work.
In XF86Config added.

Option "NoDDC" "true"

In NVIDIA_kernel package edited os-registry.c

static int NVreg_SoftEDIDs = 0;
static int NVreg_Mobile = 4;

make install


P.S.
You English guys are awesome. Long live the queen!
