Server: SUN FIRE X2270 M2
Solaris version: Oracle Solaris 10 8/11 s10x_u10wos_17b X86

Problem: cannot get server output VGA port (monitor).

Symptoms: I can see POST messages as well as GRUB menu but then black screen with cursor blinking in the upper left corner of screen.
Same behavior through ILOM.
Console redirection (when server is up) shows black screen with cursor blinking....
Server is fully operational except VGA output.
Console redirection is disabled in BIOS.

/rpool/boot/grub/menu.lst
default 0
timeout 10

You need to reconfigure X. Sun documents it pretty well, but best to google how to reconfigure X for solaris.   The trick is to make sure your monitor supports the resolution you are defaulting to.  

Also know what the specs are for your monitor, including horizontal & vertical frequency, or you can fry it.


Check this out
http://docs.oracle.com/cd/E26502_01/html/E28056/gmcdj.html  [but not necessarily correct for your flavor of solaris, I just did a quick search, still it is probably OK]

The console is being redirected to serial (ttya)
Terminal session.

To dlethe:
I assume that X is not the first process which starts after booting.
Shouldn't I see other processes starting till X and after that monitor would go blank?

To arnold:  
Your statement is based on what?
Console redirection in BIOS is disabled.
System boots using command kernel$ /platform/i86pc/multiboot -B $ZFS-BOOTFS.

kernel /boot/multiboot -s -B console=ttya

Attach a terminal to the serial port of your x2200 and see the output shift there.
Not sure whether disabling console redirection in the BIOS blocks it.
