You may want to try this option if the mouse pointer is not drawn correctly or the font does not seem to be loaded properly on the VGA card. However, it may cause flicker on some systems.
VGA_SLOW_IOACCESS
Older VGA cards may require this option for proper operation. It makes the driver perform byte-wide I/O to VGA registers and slow down a little.
VGA_WIDTH90
This option enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These modes are not always supported by the video card and the display. It is highly likely that LCD display cannot work with these modes.
The following options add optional features to the driver.
VESA
Add VESA BIOS support to the driver. If the VGA card has the VESA BIOS extension 1.2 or later, this option will utilize the VESA BIOS service to switch to high resolution modes.
VESA_DEBUG=N
Set the VESA support debug level to N. The default value is zero, which suppresses all debugging output.
The following options will remove some features from the vga driver and save kernel memory.
VGA_NO_FONT_LOADING
The vga driver can load software font to EGA and VGA cards. This option removes this feature. Note that if you use this option and still wish to use the mouse on the console then you must also use the SC_ALT_MOUSE_IMAGE option. See syscons(4).
VGA_NO_MODE_CHANGE
This option prevents the driver from changing video modes.
