FIXED PATCH 2c-hid: Add a small delay for Synaptics/Elan touchpanel
Synaptics/Elan touchpanel sometimes does not work in desktop session although it works in display manager. During user logging, the display manager exits, close the HID device, then the device gets runtime suspended and powered off. The desktop session begins shortly after, opens the HID device, then the device gets runtime resumed and powered on. If the trasition from display manager to desktop sesesion is fast, the touchpanel cannot switch from powered off to powered on in short timeframe. So add a small delay to workaround the issue. ** Patch added: "i2c_hid_fixed.patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1807377/+attachment/5226680/+files/i2c_hid_fixed.patch -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1807377 Title: i2c_hid i2c-ELAN2514:00: failed to change power setting.
