Description Mamy Ratsimbazafy 2011-08-20 09:30:51 UTC

Version:           4.7 (using KDE 4.7.0) 
OS:                Linux

Hello,

Everytime I plug an USB device on my laptop it suspends. My laptop is an acer 4930G.

I've narrowed down the issue to the process named : kdeinit4: kglobalaccel [kdeinit] .

When setting the keyboard shortcut for sleep to none, this doesn't happen anymore.

This happens with mass storage devices (usb key/hdd) and also with a USB mouse, I didn't try any other devices.

This happens in kde on a new user profile, but not in tty.

I'll be happy to help you in your investigation. See this thread for a similar and probably duplicate problem https://bbs.archlinux.org/viewtopic.php?id=116288

Regards
Mamy

Reproducible: Always

Steps to Reproduce:
Plug in an USB device when Sleeping is set to the sleep shortcut (System settings > shortcuts and gestures > global shortcuts > kde-daemon > sleep)

Actual Results:  
Laptop is suspending

Expected Results:  
Laptop is not suspending

Hello,

further testing shows that it it is not kde related.

I use the following scripts when booting up for power management :

for i in /sys/bus/{pci,i2c}/devices/*/power/control; do echo -n 'auto' > $i; done

When I don't load the pci part, the sleeping doesn't happen anymore. It seems like this setting will send a sleep keyboard event when a USB device is connected. KDE interprets it and suspend the computer. I'll file this to kernel devs.
