Bug 1390772

It's not sending any events? What's the output of evemu-record when you move the mouse?


(fwiw, xorg-x11-drv-mouse hasn't been used in a couple of fedora releases)

Sorry, I'm not so tech savy in Linux. Actually, I remember now, that I coudln't use any mouse at all - I connected a simple usb optical mouse, and it didn't work either.
So I didn't explored too much, as I didn't have the mouse.
The 'non-working mouse' problem also exists on the latest kernel of Fedora 24 (4.8?), but it doesn't exist (mouse/s work fine) on Fedora 24 kernel 4.5..

start your plug the mouse in, and run  "dmesg > dmesg.out" immediately after that, then attach the dmesg.out file here please. This should tell us whether the mouse is recognised at all. If so, it should show up when you run "sudo evemu-record" and you should be able to check if you get events from it.

If so, post the output from this command "journalctl -ef _COMM=gdm-x-session" which should tell us why X doesn't recognise it.

1. dmesg.out attached.
2. Tried the newest Fedora 25 from today - the same problem
3. 2 mice are connected (G900 & simple optical usb mouse from HP)
4. "sudo evemu-record"  - all devices are recognized, but on move works for HP usb optical, but NOT for Logitech G900
5. "journalctl -ef _COMM=gdm-x-session" yields absolutely nothing: "Logs begin at.." and nothing after that.
6. Mouse pointer stuck at the top left corner, right click seems to be working (and maybe left too), but no move.

this one shows only the USB mouse from HP (event though it's listed as Logitech Optical USB Mouse). The g900 doesn't show up anywhere, so it doesn't seem to be detected by the kernel. Is it connected over USB or with a receiver?

so you're not getting any events from the 900 but you do get the device description? Can you attach that one please?

are you using GNOME or some other DE? If some other, attach your /var/log/Xorg.0.log please

run sudo libinput-debug-events, does the output of that make sense? i.e. movements/buttons show up as you move the mouse?

Googled enough and it seems to be a very specific problem with my Nvidia 1070 GPU.

Therefore, I've resolved the issue, by installing NVidia driver following this guide:

ok, thanks. I'll close this bug now.
