@Lakotaubp the part where you have to allow permission messes a lot of people up, nothing will happen until you do this.
you can flash TWRP with the flash-tool , and flash a presaved version ,if some one has one , (but run a backup, just to get the twrp (backup ) folder on your device) then go from there

@matteo ok, thought it might help,as it is annoying reentering, as there is no option to reconnect.
all your "symptons", are the same as on my m10 fhd.
except the "nvram 0x10 error " .
did you try the "skyneel" fix tho.

Your WiFi worked with Android, but did you get a WiFi service called " nvram error 0x10".
If you did and you flash UT, it will not show this error, and you will need to re-enter the wifi ,every time you restart it
Put TWRP on your device, flash the nvram zip, from " xxx.skyneel.com" check it out ,reflashing stock recovery,as needed, ota updates fix usually stays, .

See if it works for you , while you figure something else out

@ubuntoutou
I had this on my m10 fhd, i used the fix on xxx.skyneel.com,which is flashed with twrp, it will stay, thru ota updates ,but if you change rc,to stable etc, you need to reflash it.
I know how annoying it is reentering the passwords !
it says it is for mtk devices ,worked for me tho.

try searching EBAY

I use this on my M10fhd to fix wifi losing password.
maybe you could search this website for ideas.

How about reflashing the original ,it came with, as behind Ubuntu is Android which controls the screen - if I am wrong ,I am sure someone will correct me.
Trying to give you some ideas, as it is holiday time ,and the usual experienced guys ,may not be available.

Have you searched BQ forums ?

will BQ support help you with this, my guess is that this is in the android side of things .
can you use flash-tool to go back to android , see if you can sort the touch screen, ""or it may automatically fix it "" then restore UB.
