Setting console resolution

I am running Solaris 11 Express and booting into console mode - that is, I am not starting X or gdm.

My Dell Inspiron 8600 has a resolution capacity of 1680x1050, which works fine in X/Gnome, but my console resolution is low - something like 1024x768. How to I set the console resolution higher?

I have tried adding vga=369 or vga=ask to the kernel line during boot, but it says

krtld: Unused kernel arguments: 'vga=369'

and gives me the normal 1024x768 resolution.

have you tried "kdmconfig" ? (I presume that still exists in Solaris 11)

kdmconfig isn't installed and isn't available in the package manager.

From what I can tell, kdmconfig is legacy software used for configuring the Xsun window system environment, which has been replaced by X11.

yes, Xorg precisely. Have a look at its logs for clues: /var/log/Xorg.0.log

Let me reiterate... I am NOT RUNNING X.

Within the X/gdm environment there is no problem with the resolution. It is the CONSOLE resolution that is the problem.

Then your resolution is fixed by the BIOS default text mode to 640x480, 80x25 characters. There is no way I'm aware of to switch to alternate text modes under the Solaris console.
