Gigabyte GA-G41M-Combo

Gigabyte GA-G41M-Combo Rev. 2.0 + Intel Core 2 Duo + Hitachi CM821F

Issues:

1) Multiple “[pulseaudio] alsa-util.c: Unable to load mixer: Invalid argument” in “/var/log/messages” and no sound from onbord audio (Realtek ALC887).

2) An absurd screen resolution.

Solutions:

1) Multiple “[pulseaudio] alsa-util.c: Unable to load mixer: Invalid argument” in “/var/log/messages” and no sound.

Solved with

#echo options snd_hda_intel model=auto >> /etc/modprobe.d/alsa-base.conf

(solution by Aditya Goturu).

2) An absurd screen resolution.

Solved with explicit specification of the modelines in “/etc/X11/xorg.conf”:
