Sound

Headphones don't have sound after suspend or reboot:

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1313904 you can download the init-headphone_0.2.0_all.deb at the bottom of the comments. run sudo init-headphone. If it tells you that your product is not supported (and you know for sure it's a w230ss), you can edit the executable. sudo vim /usr/sbin/init-headphone and edit line 8: SUPPORTED_SYSTEM_PRODUCT_NAMES = ["W230SS"] to fit your product, for me it was: SUPPORTED_SYSTEM_PRODUCT_NAMES = ["M4"]

UPDATE:

After upgrading to Kubuntu 15.04, the fix doesn't automatically work. I end up having to change the script again and remove the check for i2c_dev, this is because i2c_dev is incorporated into the kernel by default.

UPDATE 2:

Unrud commented underneath that the Eurocom M4 is now supported on his GitHub repository I haven't tested but could save you time.

Changes to script:

/usr/sbin/init-headphone line 86 to 95

for line in modules_file.readlines():
# if "i2c_dev" == line.split()[0]:
#     module_i2c_dev_found = True
if "i2c_i801" == line.split()[0]:
module_i2c_i801_found = True
#    if not module_i2c_dev_found:
#        print("Warning: Module i2c_dev is not loaded", file=sys.stderr)
if not module_i2c_i801_found:
print("Warning: Module i2c_i801 is not loaded", file=sys.stderr)
return True

Then run these in terminal:

# modprobe i2c-dev
# modprobe i2c-i801
# init-headphone

If this doesn't work, you may need to install libi2c-dev:

# apt-get install libi2c-dev

Network:

WiFi

random disconnections:

This one is annoying, it randomly disconnects but the WiFi icon doesn't show it disconnects, you end up having to disconnect and reconnect manually to regain a connection, only to lose it again in 15mins~few hours.

Side Note: This is a very nice script which would help troubleshoot wireless problems. _Reference: http://ubuntuforums.org/showthread.php?t=370108_ Mirror gist: wireless script

The command which seem to fix it for me:

Posted by varunendra

# echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

and reboot:

# reboot

hm, just got a hiccup, it seemed to disconnect for about 10~15 seconds and then reconnected, might be other network issues, so I'll try to monitor it.
