I recently got my hands on a Dell Latitude E7470 and installed Fedora Workstation. Even though I enabled two finger scroll (and disabled touchpad edge scroll), the right side of the touchpad still has a dead zone of considerable size. So, when I start a mouse movement too far on the right side, it wont register.
I tried a few things, like adding quirk configs, but the zone is still there. Bios had no option to disable. (I reinstalled with UEFI, prior installation was legacy uefi / bios, so I have to give it a look again).
Does someone have a way to disable the dead zone?
Also, the fingerprint sensor doesn't work. From what I could research, it is a broadcom device with officials drivers for MS and Ubuntu. I tried some stuff to get this thing running, but it didn't work out. I still have to try a bios update after the reinstall. Is there a way to get this thing running under Fedora? It's not a crucial feature, but a nice to have for sure.
If you got it second hand, could it be a defective touchpad?
I don't think so. If the movement starts outside the "dead zone", the touchpad works fine even within the "dead zone". Only if the movement starts in the dead zone, it's actually dead and its exactly the size of the "edge scroll zone", when the option is enabled.
I had a Dell Latitude at work a few years ago, I don't know if it was this exact model number, but the same series. And iirc on there was a driver option to disable the "dead zone" under microsoft.
Try Linux Mint or Ubuntu live usb and see if it has the issue fixed for you. If yes, check if they have a different config and copy it over. If not, but it still works better, you might want to move to a debian-based distro. If it also doesn't work, maybe not much you can do, might be one of these weird dell touchpads that don't work correctly -- i have one of these...
Oh, Live USB is a good idea.
I really wanted to give Fedora a try, but maybe the time has come to give Ubuntu a second chance, when theres no solution.
