What the hay!? Then I went and started perusing the kernel vga driver sources. There is a LOT of functionality in there for various stuff (e.g. diddling cursor, getting its location, setting border color, loading fonts, and on and on) and it seems to me that all of that functionality should be brought out and made directly available in user land. No? More specifically, I personally would like to be able to get at the VESA functionality. In particular , I'd like to be able to switch my monitor into power-saving VESA "standby" mode. Surely, there ought to be an ioctl() for THAT! Oh yes, and if this gets fixed, and if all of the functionality is ever made available at the user level, PLEASE also create a file called /usr/include/vgaio.h and put all of the IOCTL control code definitions in it. Thanks. P.S. I'd really _like_ to go and rag on the Xfree86 people and tell them to get their you-know-what together, and that they should be supporting the VESA "standby" power-saving mode in their X servers, but how can I do that when the FreeBSD kernel doesn't even permit user-land processes to get at this bit of hardware functionality? >How-To-Repeat: man 4 vga >Fix: Jump in your time machine and fast forward to the future, when, I'm sure, all of this functionality will be directly available in user land. :-) >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
