monitor not returning from power saving mode Debian etch
The situation is as follows: The monitor displays POST, then LILO, then booting, but somewhere in the init process the monitor shuts off and remains off until it wakes up on shutdown -r now, at which point one can switch between virtual consoles and see the messages that root has echoed to for instance /dev/tty4. Any ideas? It's not a wiring problem. -- But some very large rats, Ate his coats and his hats, While that futile old gentleman dozed. http://cronos.advenge.com/pc/nonsense/nonsense27.html
In certain situations with older monitors. Make sure the bootup is not trying to change into SVGA mode at boot. A lot of distros try to change into SVGA mode asap. Something like "no-framebuffer" at boot should fix it. David Nicol wrote:

looks like a known enough bug that lilo knows about it, but I guess it doesn't work around it by default #lilo -T video VGA/VESA adapter: 640x350x16 mode 0x0010 640x480x16 mode 0x0012 320x200x256 mode 0x0013 640x480x256 mode 0x0101 800x600x256 mode 0x0103 Enable Screen Refresh bug is present.

Clearly. Have you tried appending nofb or vga=normal to the boot command? Are you booting to X or console?
How old is your monitor and your video card? Sounds like a problem with the power saving code. I googled, and here's a set of posts that might help you: http://www.neowin.net/forum/lofiversion/index.php/t616183.html J. On Fri, Jul 11, 2008 at 3:02 PM, David Nicol <davidnicol@gmail.com> wrote:

Aside from I thought etch came with grub by default... It shouldn't matter which bootloader you use. Reading the description in the body of your message, it sounds like Xorg and the 'graphical boot' thing are set to some frequency or resolution which your monitor does not support. As J Hutchins mentioned. Try booting with the 'nofb' kernel option. Also, just try the option '3' and even if the "graphical boot" (init scripts) happen with a black screen, it should stop at a text terminal, from which you can fix Xorg.conf, and test with startx and [ctrl]+[alt]+[Backspace].
