Created attachment 113134 [details] journalctl output When I wake up my machine from sleep it sometimes happens to lose keyboard and touchpad controls(no input). It happens frequently with lightdm (about 1 in 3 wake-ups) and not that often with gdm (1 in 10+ wake-ups). This only happens to the integrated input components, external usb mouse works fine. The bug is distro agnostic (successfully reproduced it in Ubuntu 10.04 and latest Arch) while using various versions of kernel (3.13 up to 3.18.5), mesa (10.3 - mesa-git) and xserver (3.15-3.16). I attached here the relevant output produced by journalctl (crash.log) I posted this in the radeon section but I'm not sure at all if it's a radeon issue. I'm apologise if this turns out to be unrelated to radeon.

The radeon driver doesn't have anything to do with the keyboard or touchpad so I doubt it's related. I guess this is probably related to the kernel input drivers or maybe some special platform handling for your system.
Ok Alex, thanks for reassigning it.
please run evemu-record against the device after you lost input. do you still see events from the kernel?
Is it ok if I run evemu after rebooting or not? Because when I loose input I lose it for good, it doesn't come back until I reboot my laptop. (I can't log in, can't do commands) When this happens I usually plug my external usb mouse and do a reboot from GDM. But if this is not ok, I guess I can lookup an external usb keyboard and do the test with that.
Ok, so I have some updates. I managed to obtain the info by using only the external mouse. First difference: When executing evemu-describe under normal circumstances I get: [code] /dev/input/event0: AT Translated Set 2 keyboard /dev/input/event1: 2.4G Wireless Keyboard&Mouse /dev/input/event2: 2.4G Wireless Keyboard&Mouse /dev/input/event3: Video Bus /dev/input/event4: Video Bus /dev/input/event5: Lid Switch /dev/input/event6: Power Button /dev/input/event7: Sleep Button /dev/input/event8: Power Button /dev/input/event9: PC Speaker /dev/input/event10: Asus WMI hotkeys /dev/input/event11: HDA ATI HDMI HDMI/DP,pcm=3 /dev/input/event12: USB Camera /dev/input/event13: HD-Audio Generic Mic /dev/input/event14: HD-Audio Generic Headphone /dev/input/event15: ETPS/2 Elantech Touchpad [/code] After I lose input evemu-describe will not show the touchpad at all only the other devices. (will still display the integrated keyboard) I then went on and executed evemu-record on the integrated keyboard, and indeed, no event is recorded and displayed when pressing keys.
If the device disappears that'd be a kernel bug then. CC-ing Hans and Benjamin, let's see if there's something obvious here.
I'm afraid I don't have anything useful to add there, there are no known elantech issues where an elantech touchpad disappears after a suspend/resume, so this seems to be something new. Adrian, can you please collect the output of dmesg after a suspend / resume where the touchpad is gone ?
@Hans de Goede. Thank you for helping me! I'll attach a dmesg output but it might take a few days; resume freezes happen less these days (but still happen nonetheless). Anyway, isn't the journalctl output file above of any help? It records a failed resume. The computer went to sleep at 20:59:26 and woke up in a failed state (no input) at 21:51:14. For example these two lines : --feb 03 21:51:15 adrianPC gdm-Xorg-:0[297]: (II) config/udev: removing device ETPS/2 Elantech Touchpad --feb 03 21:51:15 adrianPC gdm-Xorg-:0[297]: (II) UnloadModule: "synaptics" Everything from 22:15:55 onward is recorded after a system reboot. (shouldn't be of much interest/importance).

Ah yes, the journalctl output includes the dmesg bits from after the resume, no clue there really wrt what is wrong though. Can you please do "lsmod" and provide the output here ?
Output of a 'good' (with input) lsmod.

Hi again, Ok, so asus_wmi may be causing issues here, and having serio_raw listed is weird too, try creating a /etc/modprobe.d/blacklist.conf with the following in there: blacklist asus_nb_wmi blacklist asus_wmi blacklist serio_raw Then reboot and check lsmod for those modules not being listed, and after that just use the laptop and see if the suspend/resume issue is gone. If it is gone try re-enabling either the asus modules or the serio_raw one to pinpoint the issue. Regards, Hans
Hi. Well..that solution didn't work after all. Lost input twice already with those 3 modules blacklisted.
I'm afraid I'm all out of ideas then. This sounds like an ACPI embedded controller bug. Have you tried updating your BIOS to the latest version ?
No I didn't...but I doubt that's the case. I constantly dual-boot with windows. And in windows the problem never appears.
Hmm, So one last thing which you can try is adding: "i8042.nomux=1" to your kernelcommandline and see if that helps. Regards. Hans
Haven't tried your last suggestion yet Hans but I would like to ask you a question. When looking over the kernel's output messages upon resume I found these: [ 4472.923364] atkbd serio0: Unknown key released (translated set 2, code 0x7c on isa0060/serio0). [ 4472.923366] atkbd serio0: Use 'setkeycodes 7c <keycode>' to make it known. [ 4473.121833] atkbd serio0: Unknown key released (translated set 2, code 0x7c on isa0060/serio0). [ 4473.121836] atkbd serio0: Use 'setkeycodes 7c <keycode>' to make it known. [ 4473.322394] atkbd serio0: Unknown key released (translated set 2, code 0x7c on isa0060/serio0). [ 4473.322397] atkbd serio0: Use 'setkeycodes 7c <keycode>' to make it known. Can't they somehow link to the problem and what exactly might they mean. Regards, Adrian
Unfortunately the problem still occurs if booting with i8042.nomux=1 :(
fwiw, this isn't a libevdev bug, it looks like something in the kernel so I'm closing this bug for now. Feel free to continue the discussion here though
