14.04 on Gigabyte P34Wv4-BW1T: no sound, no bluetooth, 2nd hdmi monitor blacks out

[ravimannan2002]

Hi Folks! ):P
I purchased a sweet new laptop and now I'm trying to get Ubuntu 14.04 to work on it. I went through some of the basic troubleshooting steps and I still couldn't get it to work. Please help!
Here's some diagnostic output. I hope somebody has a good idea to help me.
The problems I'm having so far:
1. no audio from laptop speaker. headphone jack is ok.
I went into alsamixer and unmute everything ("00")
Auto-Mute Mod --> Disabled
Press FN+F7 (my laptop "unmute" button) for the millionth time.


2. no bluetooth I had to go into my bios settings and enable bluetooth.
3. 2nd hdmi monitor blacks out
4. wireless keyboard/mouse from nano usb randomly stops working

Update: I did a fresh install of 15.10 and I'm still having the same issues :(




My third issue is that my 2nd monitor attached via a hdmi cable blacks out every once in a while.
I'm not sure what to do here. RIght now I'm using the nouveau drivers. I might have better luck by switching to the nvidia drivers.


Hopefully my last issue is that my wireless keyboard and mouse stops working randomly for a few seconds.

This is the product:
http://www.amazon.com/Logitech-Wireless-Combo-MK270-Keyboard/dp/B00BP5KOPA
It uses a usb 2.0 RF wireless.

So obviously I'm having a few issues and I'm sort of lost. I'd appreciate some help. :popcorn:

I'll try to investigate your audio issue. I take it you still have Ubuntu 15.10 running, correct?
Please run this:

sudo update-pciids; sudo update-usbids
And then the get the ALSA info: https://wiki.ubuntu.com/Audio/AlsaInfo

I went into the alsamixer and unmuted what I could. That didn't seem to help.

For my other problem " 2nd hdmi monitor blacks out" i went from the nouveau driver to the nvidia "proprietary,tested driver" and that still didnt help. There is still one more "proprietary" driver I will try.

" 2nd hdmi monitor blacks out"

I'm using the proprietary nvidia driver now and the 2nd hdmi monitor is still giving me problems. It's like it goes into sleep mode. I have my audio playing to it (it has built in speakers) but I dont think it's related.
Here's my /var/log/Xorg.0.log right after it happens.
I dont know if the messages below are red herrings or not, to be honest.....

Here's dmesg:


[ 3954.241187] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment

It seems to happen when I am playing a youtube video and drag it from my hdmi monitor to the built-in laptop monitor. But not all the time.

4. wireless keyboard/mouse from nano usb randomly stops working
I'm still having this problem. I do a dmesg right after it happens and this is what I get:

[ 1997.626496] perf interrupt took too long (2502 > 2500), lowering kernel.perf_event_max_sample_rate to 50000

The problem of "perf interrupt took too long (2502 > 2500), lowering kernel.perf_event_max_sample_rate to 50000" seems to be a culprit. I googled that error message and other people from many years ago had that problem.
I wonder if I should make a bug report?
This is very frustrating!

I was able to get my sound to work. Now I have a problem with my hdmi monitor and usb nano wireless mouse/keyboard.
No help from anyone? C'mon Ubuntu.

I'm still having a problem with my second monitor randomly blacking out. I even tried this in windows 10 and it works fine. It's definitely a linux problem. any ideas?
