LX50 and V20/V40 are x86 machines
Ultra 5 workstations are, well, UltraSPARC machines

Those are 2 different things.

On the LX50 and V20/V40, you should use the standard Ubuntu for PC
distros (32 or 64 bit versions). These machines are servers... have no
graphics hardware. So you can directly install the server editions of

The Ultra 5 workstation might or might not work with Ubuntu for SPARC.
It's an old hardware, and Ubuntu for SPARC was built for the latest
UltraSPARC T1 and T2 processors (8 cores, 64 threads per CPU total -
Operating systems like Linux and Windows think they see 64 CPUs per
physical processor actually present in the system). There's a very
strong upwards and backwards compatibility on SPARC processors, but
still... it's fairly old and wasn't targetted in the build.
Nevertheless, on these platforms, Ubuntu for SPARC doesn't include
graphics drivers. It's a "server" edition only. So your Ultra 5
workstation may or may not work... but if it does, you won't get
graphics. You should, indeed, use the serial console.
