So i decided to enable hibernation on my computer to save power at night or between classes. When the computer wakes up everything's fine except for the trackpad which doesn't wake up.
I tired to reload the mouse module (psmouse and mouse dev) and disable and re-enable the xinput device but it didn't change a thing.
I use KDE as a DE, lightdm as DM and do not have the xf86-input-synaptics but libinput instead.
Here is the list of my xinput devices
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=16 [slave pointer (2)]
⎜ ↳ DELL0A21:00 0488:1024 Mouse id=9 [slave pointer (2)]
⎜ ↳ DELL0A21:00 0488:1024 Touchpad id=10 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Video Bus id=6 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ Intel HID events id=11 [slave keyboard (3)]
↳ Intel HID 5 button array id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)]
↳ Dell Privacy Driver id=13 [slave keyboard (3)]
↳ Dell WMI hotkeys id=14 [slave keyboard (3)]
↳ Integrated_Webcam_HD: Integrate id=17 [slave keyboard (3)]An extract of my kernel log right after resuming from hibernate (i don't know what to look for).
