After setting the graphicdriver to "nvidia" in XF86Config the LCD Display of my Notebook flickers in KDE.
Here ist an extract of my XF86Config
| Code: | Section "Monitor"
Identifier "LCD"
HorizSync 30-200
VertRefresh 50-150
Modeline "1600x1200" 162 1600 1628 1712 1912 1200 1201 1203 1220
EndSection
....
Section "Screen"
Identifier "Screen 1"
Device "nVidia GeForce4 Go"
Monitor "LCD"
DefaultDepth 24
Subsection "Display"
Depth 8
Modes "1600x1200"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "1600x1200"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "1600x1200"
ViewPort 0 0
EndSubsection
EndSection
....
Section "ServerLayout"
...
Screen "Screen 1"
....
EndSection |
I get the values for HorizSync, VertRefresh and Modline from the internet. But I don't know if they are right  . Where do I get the exact values, especially for ModeLine?
I have a Dell Inspiron 8200 with a geForce 440 Go 64MB and the Ultra Sharp LCD with 1600x1200. Maybe someone has the same notebook and can post his XF86Config. |

| I have an I8.1k w. the same screen and it works perfectly. Unfortunately I'm not at home to send you my settings, but I got mine from the linux-dell-laptops ML on yahoogroups. There is a whole section on xf86config files. |

You will probably need to adjust parts of the "NVIDIA Card" section. |

After I tried a lot of different configs without success I recognized, that the background Image effects the Illusion of an flickering LCD  . It's a dark image with 1px lines.
But the oddly thing is, that with the driver "nv" the display doesn't seem to flicker with the background image  |

| I don't think the nv driver supports the 1600 x1200 resolution. Therefore it probably interpolates the pixels thus smoothing out the flicker effect. |

emerge the nvidia driver and follow its instructions.
your horizontal sync should be 31-96, and your vertical sync you can set to 60 while you get it all working.
something like this:
| Code: | Section "Monitor"
Identifier "dell tft"
# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.
HorizSync 31 - 96
# HorizSync 30-64 # multisync
# HorizSync 31.5, 35.2 # multiple fixed sync frequencies
# HorizSync 15-25, 30-50 # multiple ranges of sync frequencies
# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.
VertRefresh 60
