My first weird question (you knew it was coming). On the old desktop I use for Linux, circa 2009, I can only run very light systems due to graphics issues. Bodhi, Bunsen Labs will work on Nouveau drivers. Ubuntu 16 works on Nvidia driver 304, but you can't install it after Ubuntu 16 as that driver is obsolete and unsupported by both Nvidia and the Linux kernel beyond 4.4. So I have Bodhi 6 going, as well as Ubuntu 16 (with extended security maintenance).
I did try getting an old video card from around that era, but it wouldn't work and I resigned myself to using only light systems. (Zorin Lite is too heavy, at least 15 was). Now, I wanted to put Zorin 16 on my wife's notebook, which I did, that's working great. but to preview it, I ran Z-16 with Safe Graphics on my old machine. I actually found it quite usable, as I have a big monitor, so the weird resolution is OK on it. In fact, my aging eyes are liking it a lot. Solitaire looks pretty funky though; the cards are kind of squashed.
anyway, I installed it from the USB, which I had booted with Sage Graphics. when I ran Zorin for the first time, it booted into regular mode, which is unusable due to screen craziness. So I booted next time into Safe mode. This manages to get me into the system with Safe Graphics. But I have to do it every time, and have to restart the computer again. So it takes two starts to get going.
Now, I'm doing this primarily to re-familiarize myself with Zorin, so I can solve whatever problems my wife runs into. But it's cool to be able to run Zorin on this old machine too. I was thinking of installing Grub Customizer, so I can set Recovery Mode as the default boot. Anybody have any thoughts on this? Is there another way to do boot into Recovery mode?
