Description Christian Timmer 2003-10-21 15:19:07 UTC
- Samsung X10 has several different versions which include either
Geforce4 420GO 32M or Geforce4 440GO 64M, but whichever the version I
and several others seem to have exactly the same problem: NVidia
driver (version 4496-r3) installs with no problem, X starts up but with patterns
of horizontal lines rather than a normal display.

- When an external monitor is connected and used instead of the
internal panel, the NVidia drivers work fine: very nice accelerated

- XFree (nv driver) works fine on the internal panel at 1024x768. Use exactly
the same config file (with nv changed to nvidia, dri commented out) with NVidia
driver and get horizontal lines.

So it seems that the problem is with syncing with the internal panel
and the way in which the NVidia driver detects/sets it up. I have
tried various different things in XF86Config: different resolutions,
IgnoreEDID (it seems that the panel's EDID returns strange values),
FlatPanelProperties, etc.

Not a real solution: When I load the nvidia driver with "modprobe nvidia
NVreg_Mobile=1 NVreg_SoftEDIDs=0" and then startx I got a readable screen with
my icons inside but it is covering only the 2/3 of the DFP. By the way glx is ok
and FPS are good :-). There is a large black part on the right. Switching
resolution does not give anything good and messing with Scale and Dither did not
If I load the module with NVreg_Mobile=2 I got messy X screen like usual.

Reproducible: Always
Steps to Reproduce:
1. emerge nvidia-kernel nvidia-glx
2. startx

Actual Results:  
Messy X-Screen.

Expected Results:  
A normal X-Screen.

Comment 1 Tim Yamin (RETIRED) gentoo-dev 2003-10-22 05:12:59 UTC
What about previous versions? What about the X11 "nv" driver?
Comment 2 Christian Timmer 2003-10-22 07:53:03 UTC
It occures with every version from the nvidia-driver. The xfree-nv-driver
works fine.
Comment 3 Martin Schlemmer (RETIRED) gentoo-dev 2003-10-27 11:05:37 UTC
Not much we can do, as the driver core is closed source.  Please report to
nVidia, and reopen if a newer driver or possible patch (if one could be made
without updating the core) fixes this.
