phgrafx [-ae] [-S i|m|n] [-s server] [-x position[%][r]] [-y position[%][r]]
- Display all the driver families.
- Expand all the branches of the tree.
- The initial state of the main window (iconified, maximized, or normal).
- -s server_name
- The name of the Photon server:
If server_name is: This server is used: node_path node_path/dev/photon fullpath fullpath relative_path /dev/relative_path
- -x position[%][r]
- The x coordinate of the upper-left corner of the window, in pixels, or as a percentage of screen width if % is specified. If r is specified, the coordinate is relative to the current console.
- -y position[%][r]
- The y coordinate of the upper-left corner of the window, in pixels, or as a percentage of screen height if % is specified. If r is specified, the coordinate is relative to the current console.
You choose the display preferences for your workstation with the phgrafx utility.
|This utility needs to have the setuid ("set user ID") bit set in its permissions. If you use mkefs, mketfs, or mkifs on a Windows host to include this utility in an image, use the perms attribute to specify its permissions explicitly, and the uid and gid attributes to set the ownership correctly.|
|The list of available graphics modes displayed in the above dialog most likely is different from those on your machine.|
The initial settings are the result of a hardware scan Photon did during the installation. The default selection is a "safe" choice based on this scan; you'll probably want to choose something better. The hardware detection program presents only options that correspond to the kind of graphics card you have. To save these initial settings, choose the Done button.
Photon supports the following settings for the color depth, depending on the capabilities of your graphics card:
|Number of colors||Number of bits|
Choose the best one!
The resolution setting that's currently in effect for your type of display is shown by an icon to the left of the setting. The default setting is 256 color with a 640*480 resolution.
The type of graphics card Photon detected is one of a family of cards that are listed in the Driver Family list (top left corner). One card may be supported by different driver families, including generic drivers. You can use the Driver Family button to select a driver.
The refresh rate determines how often the image on your display is redrawn. Selecting a higher refresh rate can produce a better screen image with less flicker, but it may slow down some graphics cards.
Setting the refresh value incorrectly can damage your monitor. Consult your monitor and video card manuals first.
The color palette is used by 256- and 16-color graphics drivers. It provides the base set of colors a graphics driver can use to display images on your screen.
Click the button beside the Palette field to choose from a list of palette files. All palette files are kept in the /usr/photon/palette directory. The default setting is symbolically linked to the photon11.pal file. For a life-like rendering of flesh tones, try portrait.pal.
Run phgrafx using Photon server on node my_node:
Run at initial position (10,10) with initial dimension of 200*300.
phgrafx -x10 -y10 -h200 -w300
- A file that contains the command lines, assembled by enum-devices, that devgt-iographics uses to detect the video modes available on your system's graphics devices.
