I am trying to port a custom linux distro to cloud. For this linux, we don't use X. We have a separate graphics/windowing system. It needs a framebuffer. Most clouds don't support any emulated framebuffer devices.
So I stumbled across this, http://cateee.net/lkddb/web-lkddb/FB_VIRTUAL.html
I am able to load it with a kernel command line option video=vfb:
But I can't set resolutions, or bpp etc. I tried many things like setting vga mode - vga=791
But nothings works. I get a default configuration of framebuffer.
What are the command line params using which vfb could be configured for a resolution and bpp ?
