Because of problems with graphics on v4.5-rc1 (maybe because I'm using intel-linux-graphics-installer, or maybe it's the i915 drivers issues) I've tried earlier kernels.
On v4.4 the bug seem to be fixed (complains about i915 firmware) On v4.3.4 the bug is still there (does not complain about the firmware) On both of them there were some display issues (flickering screen), so I had to go back to the standard 15.10 kernel. -- 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/1534260 Title: Ubuntu does not recognized wireless mouse and keyboard after startup for couple of minutes Status in linux package in Ubuntu: Confirmed Bug description: Looks like a regression after recent kernel upgrade.
