Bonjour,

Tu peux essayer en mode graphique ( XFdrake ), mais l'idéal vu ta configuration est de modifier le serveur X en mode texte et de l'adapter à ta configuration.

/etc/X11/X86config :

Voici le fichier tiré du site de X window system, attention de bien renseigner le taux de raffraichissement de l'écran.( en MHZ ou HZ )


Monitor Section
The config file may have multiple Monitor sections. There should normally be at least one, for the monitor being used, but a default configuration will be created when one isn't specified.

Monitor sections have the following format:



Section "Monitor"
Identifier "name"
entries
...
EndSection

The only mandatory entry in a Monitor section is the Identifier entry.

The Identifier entry specifies the unique name for this monitor. The Monitor section provides information about the specifications of the monitor, monitor-specific Options, and information about the video modes to use with the monitor. Specifying video modes is optional because the server now has a built-in list of VESA standard modes. When modes are specified explicitly in the Monitor section (with the Modes, ModeLine, or UseModes keywords), built-in modes with the same names are not included. Built-in modes with different names are, however, still implicitly included.

The entries that may be used in Monitor sections are described below.
VendorName "vendor"
This optional entry specifies the monitor's manufacturer.
ModelName "model"
This optional entry specifies the monitor's model.
HorizSync horizsync-range
gives the range(s) of horizontal sync frequencies supported by the monitor. horizsync-range may be a comma separated list of either discrete values or ranges of values. A range of values is two values separated by a dash. By default the values are in units of kHz. They may be specified in MHz or Hz if MHz or Hz is added to the end of the line. The data given here is used by the XFree86 server to determine if video modes are within the specifications of the monitor. This information should be available in the monitor's handbook. If this entry is omitted, a default range of 28-33kHz is used.
VertRefresh vertrefresh-range
gives the range(s) of vertical refresh frequencies supported by the monitor. vertrefresh-range may be a comma separated list of either discrete values or ranges of values. A range of values is two values separated by a dash. By default the values are in units of Hz. They may be specified in MHz or kHz if MHz or kHz is added to the end of the line. The data given here is used by the XFree86 server to determine if video modes are within the specifications of the monitor. This information should be available in the monitor's handbook. If this entry is omitted, a default range of 43-72Hz is used.
DisplaySize width height
This optional entry gives the width and height, in millimetres, of the picture area of the monitor. If given this is used to calculate the horizontal and vertical pitch (DPI) of the screen.
Gamma gamma-value
Gamma red-gamma green-gamma blue-gamma
This is an optional entry that can be used to specify the gamma correction for the monitor. It may be specified as either a single value or as three separate RGB values. The values should be in the range 0.1 to 10.0, and the default is 1.0. Not all drivers are capable of using this information.
UseModes "modesection-id"
Include the set of modes listed in the Modes section called modesection-id. This make all of the modes defined in that section available for use by this monitor.
Mode "name"
This is an optional multi-line entry that can be used to provide definitions for video modes for the monitor. In most cases this isn't necessary because the built-in set of VESA standard modes will be sufficient. The Mode keyword indicates the start of a multi-line video mode description. The mode description is terminated with the EndMode keyword. The mode description consists of the following entries:
DotClock clock
is the dot (pixel) clock rate to be used for the mode.
HTimings hdisp hsyncstart hsyncend htotal
specifies the horizontal timings for the mode.
VTimings vdisp vsyncstart vsyncend vtotal
specifies the vertical timings for the mode.
Flags "flag" ...
specifies an optional set of mode flags, each of which is a separate string in double quotes. "Interlace" indicates that the mode is interlaced. "DoubleScan" indicates a mode where each scanline is doubled. "+HSync" and "-HSync" can be used to select the polarity of the HSync signal. "+VSync" and "-VSync" can be used to select the polarity of the VSync signal. "Composite" can be used to specify composite sync on hardware where this is supported. Additionally, on some hardware, "+CSync" and "-CSync" may be used to select the composite sync polarity.
HSkew hskew
specifies the number of pixels (towards the right edge of the screen) by which the display enable signal is to be skewed. Not all drivers use this information. This option might become necessary to override the default value supplied by the server (if any). "Roving" horizontal lines indicate this value needs to be increased. If the last few pixels on a scan line appear on the left of the screen, this value should be decreased.
VScan vscan
specifies the number of times each scanline is painted on the screen. Not all drivers use this information. Values less than 1 are treated as 1, which is the default. Generally, the "DoubleScan" Flag mentioned above doubles this value.
ModeLine "name" mode-description
This entry is a more compact version of the Mode entry, and it also can be used to specify video modes for the monitor. is a single line format for specifying video modes. In most cases this isn't necessary because the built-in set of VESA standard modes will be sufficient.

The mode-description is in four sections, the first three of which are mandatory. The first is the dot (pixel) clock. This is a single number specifying the pixel clock rate for the mode in MHz. The second section is a list of four numbers specifying the horizontal timings. These numbers are the hdisp, hsyncstart, hsyncend, and htotal values. The third section is a list of four numbers specifying the vertical timings. These numbers are the vdisp, vsyncstart, vsyncend, and vtotal values. The final section is a list of flags specifying other characteristics of the mode. Interlace indicates that the mode is interlaced. DoubleScan indicates a mode where each scanline is doubled. +HSync and -HSync can be used to select the polarity of the HSync signal. +VSync and -VSync can be used to select the polarity of the VSync signal. Composite can be used to specify composite sync on hardware where this is supported. Additionally, on some hardware, +CSync and -CSync may be used to select the composite sync polarity. The HSkew and VScan options mentioned above in the Modes entry description can also be used here.
Option "DPMS" "boolean"
Set whether DPMS is enabled for the monitor. The default is taken from the monitor's DDC/EDID information if available, or false if not.
Option "TargetRefresh" "refresh"
Sets a target refresh rate to use for the monitor. If the monitor has valid modes with a refresh rate greater or equal to this value, those with a lower refresh rate will not be considered when determining the default resolution to use. This is improves the default resolution selection when none is specified explicitly. Default: TargetRefresh not used.
Option "SyncOnGreen" "boolean"
Set whether sync-on-green should be enabled. The availability of this option is driver-specific. Default: false.
Option "PreferredMode" "XresxYres"
Sets a preferred resolution to use for the default mode. By default the preferred mode resolution is taken from the DDC/EDID data if it is available and if it is provides a default mode preference. This is typically true for flat panel displays, which have a native/preferred resolution. This option is not used of the UsePreferredMode option is false.
Option "UsePreferredMode" "boolean"
Controls whether or not a preferred mode, either detected from the monitor's DDC/EDID data or provided explicitly with the PreferredMode option, is used. Default: true.
Options
Additional Option flags, including driver-specific options, may be included in Monitor sections.
