I'm trying to boot in a CRT TV that can only make PAL-M and 60Hz (the size can be 640x480, 800x600 and 1024x768, 8, 16 and 32bit color). However, the LiveCD insists to change to 85Hz after I select Start or Install. I cannot read the screen propelly, it's out of sync and keep running fast vertically. It's also in grayscale (NTSC). Adding vga=769 as boot parameter don't fix it. After the boot, presseing Ctrl+Alt+F1 and blindly typing "xrandr -r 60" don't fix it as well.
