![]() Add module options for console and fb_defio Convert fb_defio on/off switch to module option and add console option. >From the command line, pass options to modprobe modprobe udlfb defio=1 console=1 Or for permanent option, create file like /etc/modprobe.d/options with text options udlfb defio=1 console=1 Accepted options: fb_defio Make use of the fb_defio (CONFIG_FB_DEFERRED_IO) kernel module to track changed areas of the framebuffer by page faults. Standard fbdev applications that use mmap but that do not report damage, may be able to work with this enabled. Disabled by default because of overhead and other issues. console Allow fbcon to attach to udlfb provided framebuffers. This is disabled by default because fbcon will aggressively consume the first framebuffer it finds, which isn't usually what the user wants in the case of USB displays.
