Here comes a list of video options that I have used on my (ZorroII) box:
amiboot -k vmlinuz root=/dev/sda4 video=virge:virge8 amiboot -k vmlinuz root=/dev/sda4 video=virge:640x480-8 amiboot -k vmlinuz root=/dev/sda4 video=virge:800x600-8 amiboot -k vmlinuz root=/dev/sda4 video=virge:1024x768-8 amiboot -k vmlinuz root=/dev/sda4 video=virge:1280x1024-8
You can use virge8 or virge16 to get a standard 8 (or 16) bit mode, currently this is set in the source to use the 800x600 resolution.
You can specify the resolution and depth as in
XRESxYRES-DEPTH.
The resolutions supported during boot are:
640x480, 768x576, 800x600, 1024x768, 1152x886, 1280x1024, 1600x1200.
Resolutions 1024x768 and higher can also be used as interlace
modes (append an i after the depth).
Also supported is one double scan mode at 320x240, ie
320x240-8d.
The supported depths are 8, 16 and 32 (32-bit not tested on ZorroII).
fbset 1024x768-75 # resolution of 1024x768 with fV of 75Hz fbset -a 800x600-80 # switch all consoles to 800x600 with 80HzTo change the resolution for your X11 display, you should consult /usr/doc/xserver-fbdev/README.Debian.
For xdm, this was reported to work:
"openvt -c 7 -- fbset" (assuming that X is on vt7) in /etc/init.d/xdm just before the X server is actually started.
You can also change the resolution within a running X "on the fly" by ctr-alt-+ (or -) provided your XF86Config is configured properly.
SubSection "Display" Depth 8 Modes "1024x768" "800x600" "640x480" Virtual 1024 768Besides the Modes, you also have to supply a Virtual resolution (currently only tested with X 3.3.6).
