Whilst I've never used Debian before, I've plenty of experience in other Linux distro's. I've just re-flashed my Gemini to a rooted Android and Debian, and I'm having a few issues with the Debian side of things.
First. The LXQt desktop. I've not used this, being a long time devotee of KDE. Is the LXQt desktop environment the only alternative for the Gemini version? To my eye this desktop environment does not sit too well on the small screen of the Gemini. Not having fingers like knitting needles, the area covered by a fingertip is enormous compared with the effective size of the icons. I could go to using a mouse, but portability is all. I've no problem with a normal mobile phone, since the contrast in icon size is not so extreme, and the close proximity of a keyboard does not interfere.
Second. This is a bit of a killer. Nowhere in any of the options available on the screen, can I find any way of setting up the WiFi connection. A portable unit without a WiFi connection is not going to get me far.
Third. As a spin off from the second I've been unable to locate anything related to adding extra functionality, like FTP clients, Firefox and the ilk, and in conducting software updates, and such. My background is in UNIX admin, and this concept of no superuser does not sit too well with me, along with a fair number of associated things. My current distro, of choice, Mageia, ticks most of the boxes for organisation and admin.
Four, and connected in a fashion with three. As a UNIX man I'm wedded to the multi user ethic. I like my own space, mine alone to organise. Even though as someone living alone, it's extremely unlikely that the Gemini will ever be used by anyone else. So, I accessed the users and groups side of thing to setup a new user. Being new to Debian, and noting the usual total absence of any specific explanation of things, I put in the usual info and accepted the rest as default values. It all appeared well. I closed the machine down and re-booted, expecting that there would now be two users to log into. However there was only the default Gemini. I logged in to that, having ascertained, previously, what the defaults user password was. No Brownie points for logic here. Looking at the users and groups function again, there was no mention of a new user, merely Gemini and nobody. Thinking that the adding a new user had actually failed, I went again through the process of adding a new user. However that failed, and I was informed that there was already a user of that name.
Sorry to have been a bit long winded, and raising more than one subject, but a proper explanation requires a full explanation.
