|
---|
| 7 | * Usage:
|
---|
| 8 | * - use kernel option 'vga=xxx' or otherwise enable framebuffer device.
|
---|
| 9 | * - put somewhere fbsplash.cfg file and an image in .ppm format.
|
---|
| 10 | * - run applet: $ setsid fbsplash [params] &
|
---|
| 11 | * -c: hide cursor
|
---|
| 12 | * -d /dev/fbN: framebuffer device (if not /dev/fb0)
|
---|
| 13 | * -s path_to_image_file (can be "-" for stdin)
|
---|
| 14 | * -i path_to_cfg_file
|
---|
| 15 | * -f path_to_fifo (can be "-" for stdin)
|
---|
| 16 | * - if you want to run it only in presence of a kernel parameter
|
---|
| 17 | * (for example fbsplash=on), use:
|
---|
| 18 | * grep -q "fbsplash=on" </proc/cmdline && setsid fbsplash [params]
|
---|
| 19 | * - commands for fifo:
|
---|
| 20 | * "NN" (ASCII decimal number) - percentage to show on progress bar.
|
---|
| 21 | * "exit" (or just close fifo) - well you guessed it.
