viafb_active_dev
此选项用于指定活动设备。（CRT、DVI、CRT+LCD...）DVI 代表 DVI 或 HDMI。例如，如果要启用 HDMI，请设置 viafb_active_dev=DVI。在 SAMM 情况下，viafb_active_dev 的前一个是主设备，后一个是辅助设备。

例如

要仅启用一个设备，例如 DVI，我们可以使用
modprobe viafb viafb_active_dev=DVI
要启用两个设备，例如 CRT+DVI
modprobe viafb viafb_active_dev=CRT+DVI;
对于 DuoView 情况，我们可以使用
modprobe viafb viafb_active_dev=CRT+DVI
或
modprobe viafb viafb_active_dev=DVI+CRT...
对于 SAMM 情况

如果 CRT 是主设备，DVI 是辅助设备，我们应该使用
modprobe viafb viafb_active_dev=CRT+DVI viafb_SAMM_ON=1...
如果 DVI 是主设备，CRT 是辅助设备，我们应该使用
modprobe viafb viafb_active_dev=DVI+CRT viafb_SAMM_ON=1...
viafb_display_hardware_layout
此选项用于指定 CX700 芯片的显示硬件布局。

1 : 仅限 LCD

2 : 仅限 DVI

3 : LCD+DVI（默认）

4 : LCD1+LCD2（内部 + 内部）

16: LCD1+ExternalLCD2（内部 + 外部）

viafb_second_size
此选项用于在 SAMM 情况下设置第二个设备的内存大小（MB）。最小大小为 16。

viafb_platform_epia_dvi
此选项用于在 EPIA - M 上启用 DVI

0 : EPIA - M 上无 DVI（默认）

1 : EPIA - M 上有 DVI

viafb_bus_width
当使用 24 位总线宽度数字接口时，应设置此选项。

12: 12 位 LVDS 或 12 位 TMDS（默认）

24: 24 位 LVDS 或 24 位 TMDS

viafb_device_lcd_dualedge
当使用双边面板时，应设置此选项。

0 : 无双边面板（默认）

1 : 双边面板

viafb_lcd_port
此选项用于指定 LCD 输出端口，可用值为 “DVP0” “DVP1” “DFP_HIGHLOW” “DFP_HIGH” “DFP_LOW”。

对于 CX700 上的外部 LCD + 外部 DVI（外部 LCD 在 DVP0 上），我们应该使用
modprobe viafb viafb_lcd_port=DVP0...

注意

在启用 DVI 过扫描的情况下，对于“640x480” PAL 模式下的 DuoView CRT 和 DVI 显示，CRT 可能无法正常显示。
SAMM 代表单适配器多显示器。它与多头不同，因为 SAMM 在驱动程序层支持多显示器，因此 fbcon 层甚至不知道它；SAMM 的第二个屏幕没有设备节点文件，因此用户模式应用程序无法直接访问它。启用 SAMM 时，viafb_mode 和 viafb_mode1、viafb_bpp 和 viafb_bpp1、viafb_refresh 和 viafb_refresh1 可以不同。
当控制台依赖 viafbinfo1 时，动态更改分辨率和 bpp，需要调用 VIAFB 指定的 ioctl 接口 VIAFB_SET_DEVICE，而不是调用常见的 ioctl 函数 FBIOPUT_VSCREENINFO，因为 viafb 不支持多头，否则会导致屏幕崩溃。

使用 “fbset” 工具配置 viafb¶

“fbset” 是 Linux 的一个内置实用程序。
查询当前 viafb 信息，键入
# fbset -i
设置各种分辨率和 viafb_refresh 速率
# fbset <resolution-vertical_sync>
示例
# fbset "1024x768-75"
或
# fbset -g 1024 768 1024 768 32
检查文件“/etc/fb.modes”以查找可用的显示模式。
设置颜色深度
# fbset -depth <value>
示例
# fbset -depth 16

通过 /proc 配置 viafb¶

以下文件存在于 /proc/viafb 中
supported_output_devices
此只读文件包含一个完整的以“,”分隔的列表，其中包含您平台上可能可用的所有输出设备。可能并非所有这些设备在您的硬件上都有连接器，但它应该提供一个很好的起点，以确定哪些名称与真实的连接器匹配。

示例
# cat /proc/viafb/supported_output_devices
iga1/output_devices, iga2/output_devices
这两个文件是可读写的。 iga1 和 iga2 是两个产生屏幕图像的独立单元。这些图像可以转发到一个或多个输出设备。读取这些文件是查询 iga 当前使用哪些输出设备的一种方法。

示例
# cat /proc/viafb/iga1/output_devices
如果未打印输出设备，则此 iga 的输出会丢失。例如，如果仅使用一个（另一个）iga，则会发生这种情况。写入这些文件允许在运行时调整输出设备。可以添加新设备、删除现有设备或在 iga 之间切换。本质上，您可以写入一个以“,”分隔的设备名称列表（或单个设备名称），格式与这些文件的输出相同。您可以添加“+”或“-”作为前缀，从而可以简单地添加和删除设备。因此，前缀“+”会将列表中的设备添加到现有设备中，“-”会从现有设备中删除列出的设备，如果没有给出前缀，则会用列出的设备替换所有现有设备。如果删除设备，则预期它们会关闭。如果您添加的设备已经是另一个 iga 的一部分，则它们会在那里被删除并添加到新设备中。

示例

将 CRT 作为输出设备添加到 iga1
# echo +CRT > /proc/viafb/iga1/output_devices
删除（关闭）iga2 的输出设备 DVP1 和 LVDS1
# echo -DVP1,LVDS1 > /proc/viafb/iga2/output_devices
用 CRT 替换所有 iga1 输出设备
# echo CRT > /proc/viafb/iga1/output_devices

使用 viafb 启动¶

将以下行添加到您的 grub.conf

append = "video=viafb:viafb_mode=1024x768,viafb_bpp=32,viafb_refresh=85"
