Thats the only available driver anyways. I hate gnome as well as Ubuntu with a passion so thats not going to happen. #ArchMasterrace. I experimented with a few DEs in the initial days though. Unity was somewhat fine, Deepin was the best in terms of DPI and rotation friendlyness. HOWEVER: both were TERRIBLE in terms of performance. Couldn't do a single thing without huge lags.
P.S: The touchscreen doesn't have a digitizer. There is no different input technology. Whereas it SOMEHOW detects the Pen which is provable because it prefers the pen input over your finger input and because the evdev border on the pen are offset from the finger (max is 1930 vs 1980) the Pen input is not labeled as such inside the OS on both, Linux and Windows. There is no seperate input device for the Pen listed and Windows does not detect the tablet as "compatible with Pen input".
I spent a lot of time trying to figure exactly this out, so I am 99% sure I am right on this. If there is anything I possibly missed or if you have any other ideas though, please don't hesitate to hit me up because I would love to get this working too.
Today's laptops are making do without in-built battery (CR2032) for maintaining time and keeping BIOS settings alive. This means that whenever your battery falls to zero, the BIOS settings will reset to default and time and date will also vanish. I guess that is the reason grub is not working. The whole setup is present there but boot order is reset and hence you are booting into Windows (maybe)
Unity and Deepin are really very heavy weight so using it is out of contention. I am on the same boat as you and hated gnome a lot. Infact, I use XFCE as my daily driver because for how much screen real estate gnome eats up and the non-conventional layout. But trust me, I have used my tablet with cinnamon, kde, xfce, lxqt and gnome for more than 2 months and once you are on a touchscreen, gnome is a revelation.
And I remember reading somewhere that ubuntu 19.04 has performance optimizations to speed up responsiveness. I did not try fedora or arch to validate this but gnome in ubuntu 19.04 feels very snappy with minimal lags. The only time you are reminded that you are using a low power PC is the app load times. Rest, I dare say it is as good as XFCE in performance.
The finger input is 1930x1080 to accommodate for the touch windows key whereas the pen only reads 1920x1080. This proves that there is a separate technology powering the pen which is different from touch screen. You just have to calibrate individual devices separately in the config files (the 10-evdev.conf file) and it would work.
Can you please post the output of lshw and xinput --list when you manage to get your linux going again. And trust me, try live booting ubuntu 19.04. You are in for a surprise.
