As it seems this problem comes from the CRT hotplug detection. I have booted the kernel with this option "drm.debug=0x06" and now I see this message in my logs: kernel: [ 833.140022] [drm:intel_crt_detect], CRT not detected via hotplug
As a workaround I have tried to execut this command: echo N > /sys/module/drm_kms_helper/parameters/poll but this didn't help. It had no effect the message was still in my logs. I also asked on irc #intel-gfx for help but got no answer so far. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/758593 Title: input (mouse) hangs every 30 sec -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
