By the way, My tablet works MUCH BETTER on Ubuntu and Mint than on Windows 10. Krita and MyPaint are cross platform so I might just do my art on a *nix box instead.
I'm currently doing all of my digital drawing on an old SP3 tablet running Manjaro, via Krita. The driver support is... acceptable, I guess. Krita has more than a few annoying edges, but shows a lot of potential so I've been sticking with it.
For a long time I've been considering springing for a dedicated setup with one of Wacom's larger devices, but I've held back because I need it to have completely solid Linux support and I can't figure out how to test that in advance. I'm always curious to get more info about what issues other people have seen.
I wish I could find a physical store where I could just bring in a laptop, plug it into the actual device, and draw for maybe an hour to figure out if there are any dealbreaking problems.
I'm using a Wacom Intuos pen & touch M graphics tablet, connected to a Thinkpad 430. Over the years I was using Debian Stable, MINT, and finally Ubuntu.
The experience is great. Like I mentioned, much better than windows. I only just started to use Krita (I prefer MyPaint, however I feel I should branch out). The work I do isn't special, just stupid doodles and cartoon type of stuff. The wacom I'm using is older, I think I bought it 5 years ago or so.
I don't really have much to add besides that. I remember WAYYY back in the day having to compile the driver myself for an older wacom (Ubuntu 6 or 7 era). It's practically plug and play now, however, I think there is some other apt-get stuff that I did once for some reason that I forget (eraser wasn't working?). If you are having issues maybe try another tablet. I think the one I have can be bought for $50 on ebay. Maybe try a 30 day return place like best buy and sorry to say try the latest ubuntu or mint for compatibility (have a dedicated art machine?)
