[9fans] booting... which video modes will be accepted?

[Oliver Bandel]

Hello,


I'm back to Plan9 and to this list, and have just tried to
oot the current image.

Booting worked.
I had to use the correct boot device.
Than also I have to change the local!#S/.../data to my device.

When I came to the point to select the video-resolution,
I found no working resolution.

I tried the default; it made crazy pictures on the screen.
Following the troubleshooting-description, I typed in the
correct resolution of the LCD: 1280x1024.

I tried with 1280x1024x8 and with 1280x1024.

Both didn't worked.

When using 1280x1024x8 I thought this should be available
as minimum color resolution. Maybe I have to type in
bigger values? The message was, that in /lib/vgadb
there is no matching entry.

What value could work?


TIA,
   Oliver

Try different monitor settings. For example the documentation of my laptop
claims it to have a xga display. However, I have to set monitor=versalx to
have correct graphics. Xga should be the right setting for lcd displays
though. In my experience colour depth never was an issue (impacts on
performance of bitmap-heavy programs, notablysome in bin/games, aside).

Reading the original mail again, it looks like the graphics card is not
recognised. Have a look at
http://plan9.bell-labs.com/wiki/plan9/Installation_troubleshooting/index.html
(and submit a patch when you have found the right setting for your card).

what is your monitor setting?  if you are using the vesa
standard, you can check for available modes by using

	aux/vga -m vesa -p

some graphics cards don't work (well) in vesa mode.
some card only work in vesa mode.

so you will need to set your monitor environment
variable to try a non-vesa mode.  it's difficult to
guess what would work on your hardware.  a good
start may be 1280x1024, but it's difficult to guess.

So I have to to it again and again.

It would be fine, if there would be a loop for typing different things.
Or how can the setting be tried automatically?

What information to write into which file and which program to
start then?

Is there a rudimentary shell, in which I can type in a loop?

BTW: how to load different keyboard-settings?

Ciao,
   Oliver

Someone, who can mail me the current /lib/vgadb?

So I can directly look inside and do it systematically.
