Thanks guys. PCLOS doesn't have it either so I'm used to installing it myself. Maybe It's loyalty or conservatism, but I have looked at LibreOffice and found it doesn't suit me. The development of OO is deliberately more conservative. (By the way LO didn't "take over" OO, it forked from it to make a version more like Word - which is a strike against for me!). I edit a small local botanical magazine which has a lot of embedded pictures, and they just don't show up in the right places when I load them into LO. There are problems even with OO, but I've learned all the tricks to cope - and as they say, "You can't teach an old dog new tricks". Maybe I should be using a publishing program, but since I can do it with OO why go to the trouble of learning a whole new program at my age.
My Asus is Zenbook UX305. Since it has a relatively small memory I need something fairly light. I removed W10 altogether - not quite intentionally, but I haven't missed it. I have two partitions of about 20 GB for OSs and the rest is split into one ext4 and one fat32. These have all my data, which is accessed from either OS by way of symbolic links. This mimics my "desktop", where one of the OSs is W10 (hardly ever used) and can only access the fat32 partition. E.g my Thunderbird profile is in the W10 partition but accessed from the PCLOS installation via a symbolic link - so they are both looking at exactly the same e-mails etc. I don't use the zenbook much it's mainly to back up my files, and for its portability. One problem is that with 1080p HD resolution squeezed down to 13" the text is rather small, and I don't know how to enlarge it except on a one by one basis.
I originally was an elementary UNIX user on mainframes, so LINUX was familiar. I'm used to distros that have a proper root account, so SUDO is new to me, but I'm prepared to learn. Basically I want an OS that does what I want, not one that tells me what I ought to want!
I shall have more questions.
