I have installed Soalris 10 onto a laptop a few times to see how well it works. It does quite well.
One annoying feature though is that if you backspace all the way back to the prompt and then by mistake try to go one more, like if you hold down the backspace key, Solaris will make a really loud beep. It gets really annoying, really quickly.
To turn it off you need to run
/usr/openwin/bin/xset b 0
It also seems to do this at startup. I haven’t figured out how to disable that yet. Do you know ?
