help
Say Y here if you intend to attach a USB2VGA dongle based on a
Net2280 and a SiS315 chip.
To compile this driver as a module, choose M here; the module will be
called sisusbvga. If unsure, say N.
-
-config USB_SISUSBVGA_CON
- bool "Text console and mode switching support" if USB_SISUSBVGA
- depends on VT && BROKEN
- select FONT_8x16
- help
- Say Y here if you want a VGA text console via the USB dongle or
- want to support userland applications that utilize the driver's
- display mode switching capabilities.
-
- Note that this console supports VGA/EGA text mode only.
-
- By default, the console part of the driver will not kick in when
- the driver is initialized. If you want the driver to take over
- one or more of the consoles, you need to specify the number of
- the first and last consoles (starting at 1) as driver parameters.
-
- For example, if the driver is compiled as a module:
-
- modprobe sisusbvga first=1 last=5
-
- If you use hotplug, add this to your modutils config files with
- the "options" keyword, such as eg.
-
- options sisusbvga first=1 last=5
-
- If the driver is compiled into the kernel image, the parameters
- must be given in the kernel command like, such as
-
- sisusbvga.first=1 sisusbvga.last=5
-
