Have to manually run sudo insmod ./hid-magicmouse.ko after each restart (on Arch Linux/Manjaro) #25

Closed x-ji closed 5 years ago

x-ji commented 5 years ago

Sorry if this question is noobish. I'm not familiar with dkms. I ran the install.sh script, and it seems that dkms does install a module called 4.18+magictrackpad2. However, after each restart I can only perform single click with no other actions available.

If I run sudo rmmod hid_magicmouse, apparently the module is not currently loaded. After I run sudo insmod ./hid-magicmouse.ko, the magic trackpad works correctly (I still don't exactly know how to configure it though. The settings manager provided by the WM doesn't seem to work. Should I manually write an XOrg .conf file?).

The output of dkms status is as such:

hid-magicmouse-dkms, 4.18+magictrackpad2, 4.18.12-1-MANJARO, x86_64: installed

I wonder why hid-magicmouse-dkms and 4.18+magictrackpad2 exist at the same time. It seems that I didn't do something correctly?

Can you post the result of tail -f ~/.local/share/xorg/Xorg.0.log? Both before and after you run sudo insmod ./hid-magicmouse.ko

I tried to follow the debug guide before but couldn't find the log file. After a bit digging I found the file at /var/log/Xorg.0.log.

So it seems that the driver wasn't installed correctly after all and the device wasn't recognized at first? But when I try sudo dkms install hid-magicmouse-dkms/4.18+magictrackpad2 I get: "Module hid-magicmouse-dkms/4.18+magictrackpad2 already installed on kernel 4.18.12-1-MANJARO/x86_64"

Since you're on Manjaro (aka Arch) I'm guessing you're having problems because your distro's kernel already has a hid-magicmouse module that gets loaded when you do modprobe. My Arch has:

# find /usr/ -iname "*magicmouse.ko*"
/usr/lib/modules/4.18.12-arch1-1-ARCH/kernel/drivers/hid/hid-magicmouse.ko.xz
/usr/lib/modules/4.18.12-arch1-1-ARCH/kernel/drivers/hid/hid-magicmouse.ko

The hid-magicmouse.ko.xz comes from the distro kernel, and the hid-magicmouse.ko comes from DKMS. Try manually insmodding the hid-magicmouse.ko module. Personally, I always remove the one from the distro every time the kernel updates. It will be nice when this module is in the upstream kernel so we don't have to do that anymore!

@alanorth Thanks. This seems to indeed be the reason. After manually deleting the .ko.xz file that was originally present in the system, and reinstalling the driver, it seems to work immediately from a fresh boot. I was also encountering system freezes related to the driver. Hopefully this will solve that problem as well. Otherwise it might be an unrelated issue.
