Hi, I am writing a framebuffer device driver for a vga solution my company has developed. I used vfb.c as an example. The driver loads ok, but when I try cat /dev/zero > /dev/fb1 I get "No space left on device" and the screen does not turn black. I use fb1 because on fb0, the vfb driver is loaded so I can load / unload our own driver (it says that it is busy when loaded as fb0) Confidentiality Note: This e-mail and any attachments are confidential and the information herein is property of Quest Innovations B.V..
