Options Set In Configuration Utility

The following list of Xconfig keywords are options controlled via the Metro-X Configuration Utility. Any changes to these options should be made through the utility to avoid accidental damage to the function of Metro-X.

BitsPerPixel <number> Some X drivers support packed 24 bits per pixel memory organization. This means that each pixel takes up three bytes of video memory. In this case, configX inserts the line: BitsPerPixel 24

Buttons <number> This specifies the number of buttons on the mouse. This entry must immediately follow the Mouse entry in the Xconfig file.

Card <string> This designates the model of the graphics card in use. This is only used by configX.

Chipset <string> This displays the chipset used by the server. Normally configX inserts the correct chipset into the Xconfig file.

Clocks <number> [<number>...] This contains a list of numbers specifying the frequencies associated with the clock generator on the card. The numbers are specified in MHz.

Depth <number> This references the color depth of the screen, which controls how many colors can be displayed. Different cards and drivers support different depth values: 4, 8, 16, 24, or 32. Depth 4 supports 16 colors and depth 32 supports 16 million colors.

Dimensions <width> <height > This keyword represents the dimensions of the screen in millimeters, which is passed to X clients upon request.

DPMSoffDelay <number> This controls the number of seconds after the last user input before the screen enters DPMS off mode. Off mode provides maximum power reduction. To activate this mode, the X server disables both the horizontal and vertical sync signals to the monitor.

DPMSstandbyDelay<number> This controls the number of seconds after the last user input before the screen enters DPMS standby mode. Standby mode provides minimal power reduction. To activate this mode, the X server disables the horizontal sync signal to the monitor.

DPMSsuspendDelay<number> This controls the number of seconds after the last user input before the screen enters DPMS suspend mode. Suspend mode provides significant power reduction. To activate this mode, the X server disables the vertical sync signal to the monitor.

Driver<string> This references the name of the driver, which usually corresponds to the name of the X server. For example:

Driver 8514

initiates the section for defining the 8514 driver.

Emulate3Buttons This entry is used when a two-button mouse is emulating a three-button mouse. This entry must immediately follow the Mouse entry in the Xconfig file.

FontPath <string> FontPath is followed by a comma-delimited string of font directories. A font directory is any directory which contains fonts and a fonts.dir file.

HotKeyExit This allows you to shut down the X server with the key sequence - - . If this keyword is not present, - - does nothing special.

KbdDesc <string> The quoted string must match one of the entries in the KeyboardInfo file.

KbdDescFile <string> The string describes the keyboard.

LogFile <filename> Errors from the X server are logged here.

Modes The entries following the Modes give display mode timing information. If more than one mode is specified, the server can switch between modes. See Modes ( section C.2.4 for more details.

Monitor`` <string>'' The quoted string must match one of the entries in the MonitorInfo file. Mouse<type> [device] This describes the type of mouse in use. Type is a keyword that is OS dependant; the device parameter is usually required and is a file in the /dev directory.

MouseDesc``<string>'' The quoted string must match one of the entries in the MouseInfo file.

ScreenLayout<screen> <leftneighbor> <rightneighbor> <topneighbor> <bottomneighbor> <leftedge> <rightedge> <topedge> <bottomedge> This defines how the mouse cursor behaves when it gets to the edge of the screen. There is one ScreenLayout entry for each configured screen. The *neighbor fields tell which screen to move the mouse to. A value of -1 indicates that the mouse should stop at that edge. The *edge fields tell at which edge of the corresponding *neighbor screen the mouse will appear. Screens are numbered from 0 to 4. Edges are numbered as follows:

NOTE: Any changes made to this entry will be lost if configX is run.

ScreenLayoutIndex<number> This tells which of the predefined screen layouts was chosen in configX.

Virtual<width> <height> This designates the virtual width and height of the screen. The virtual width and height may be larger than the physical width and height if hardware panning is used.

Weight<string> This designates the RGB color specification, which is dependent on the depth value. When the depth value is 16, the options are:

R5:G5:B5 (default) or
R5:G6:B5

When the depth value is 32, the options are:

R8:G8:B8 (default) or
B8:G8:R8

When the depth value is 4 or 8, the weight value is ignored. XscreenSaverDelay This controls the number of seconds (with no input) before the screen is blanked.
