Hi guys, I have a Lenovo Carbon X1 third generation, just bought a few months ago. Everything worked perfectly but a week ago I upgraded to the new kernel version: "Linux carbon 3.19.2-1-ARCH #1 SMP PREEMPT Wed Mar 18 16:21:02 CET 2015 x86_64 GNU/Linux" After that two problems started: 1. Audio doesn't work anymore, even speaker-test fails, I already tried everything and, the audio card still comes up, but nothing happens even using speaker-test, which makes me thing it might be a hardware issue, what do you think? $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice # card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: PCH [HDA Intel PCH], device 0: ALC3232 Analog [ALC3232 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 2. Sometimes after resuming from suspension Xorg becomes crazy. I use Awesome as VM and basically it still shows something but I can't click or do anything, and the weird thing is that if I kill "Awesome" and start it again, same problem. It only starts to work normally again when I reboot the machine. The problem is not Awesome either because I tried also Fluxbox and Xfce4 but still the same problem. I can't see any clue from the logs either, any idea what I could look at? Thanks a lot PS. About 1. sometimes while listening to music the computer would give a tiny shock that made the external monitor skip and a small shock in my headset, which was very annoying, and makes me thing is a hardware issue.
