an update .. I am getting the debug messages from ioctl ... by mistake I placed the debugging messages in FBIOGET_CON2FBMAP. so if ioctl is executing, on pressing alt+ctrl+F2 the console should display on the second monitor (if i am wrong), but nothing is showing on that. sudip On Fri, Dec 12, 2014 at 1:38 PM, Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx> wrote: > Hi, > I have started with a pci based vga card. after booting i can see the > card in lspci , and after loading the driver as a module i can see > that the driver is linked with the device using lspci -k. > > for initial testing, i am using the ioctl command FBIOPUT_CON2FBMAP , > which is supposed to map a console to a particular framebuffer.
