disabling all video
Sorry if this is the wrong list to ask this.. direct me to the correct list if so...
Question: I would like the kernel not to use any of the video hardware on the machine. Is there any run-time kernel parameter I can pass to disable all video? (I tried console= to direct output to the serial port, but ttys were still using the vga hardware.) My video card is built onto the mother board, and there is no way I see to disable it from the BIOS.
I was hoping there was an option such as vga=disable or video=null or something like that, but I've looked thru the docs and cannot find anything.
Thanks,
Davy

Remove "if EMBEDDED" in the VT and VT_CONSOLE section of drivers/char/Kconfig then reconfigure your kernel.
You should find the old VT options in Device Drivers -> Character devices

Aww, is there no way to disable it at run-time? I'm working with a precompiled kernel.
Perhaps there's a trick to disable the card with a special interrupt? Set the terminal parameters to blanked from the kernel parameter line (like setterm does)
Thanks
Perhaps is there a way/trick to accomplish this by explicitly breaking (*at* runtime/kernel-parameter-time) the vga support that wouldn't cause a panic?

Perhaps there could be a way (most likely there could be), but there isn't a way currently that I can find in source files or in Documentation/kernel-parameters.txt .
