NVIDIA multiple monitors on linux

Tuesday, December 6th, 2011

The NVIDIA drivers on linux come with a nice utility: nvidia-settings
Unfortunately when setting up multiple monitors it has no easy way of saving the config.
You can save it to an xorg file, but the file created is much more than is required to set up multimonitors.

The minimal xorg file I needed was (the entire file):
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 6600 GT"
Option "TwinView" "1"
Option "TwinViewXineramaInfoOrder" "DFP-0"
Option "TwinViewOrientation" "LeftOf"

EndSection

I saved this file to (may be distro specific – I use archLinux)
/etc/X11/xorg.conf.d/10-monitors.conf

The only lines which may need changing are
Option "TwinViewXineramaInfoOrder" "DFP-0"
Option "TwinViewOrientation" "LeftOf"

The first one is setting the main X monitor (the monitor that gdm’s login and gnome shells header bar appear on). You can find the appropriate value by doing an xorg export from nvidia-settings
The second line is not intuitive – it says which direction the ‘secondary’ monitor is from the ‘primary’. This does not get the primary/secondary monitors from the TwinViewXineramaInfoOrder line unfortunately, but rather the ‘primary’ monitor is the screen used when there is no xorg config.

Options are
"RightOf" (the default)
"LeftOf"
"Above"
"Below"
"Clone"

This page from NVIDIA was quite helpful in setting this up.

Video out of sync with audio in games

Wednesday, April 20th, 2011

This problem has been frustrating me for ages. Almost every single game I played, the video appeared to run faster than the audio to match it, meaning the ends of all dialogue would be cut off – either by the next character starting to talk, or simply the end of the video it was matched with.

A lot of forums seemed to think this was related to either sound or video cards, so I uninstalled, reinstalled and tried the default windows drivers for each. I tried disabling the HDMI optical audio on the graphics card because they apparently can interfere with onboard sound.

Finally I started wondering if the clocks timer was simply wrong. Doing a bit of googling for windows 7 x64 clock sync, I eventually came across a few people whose clocks seemed to run slowly when enabling an option called CIA1 on their motherboards BIOS. It didn’t mention anything about audio in games, but I figured it was worth a shot.

I’ve got a gigabyte motherboard on my home machine and like most of them, it had an option called CIA2 with the following options “Disabled, Cruise, Sports, Racing, Turbo, Full Thrust” of course with options like that, who’s going to leave that disabled, or simply select the cruise option? Mine was set to Turbo.

After putting up with this issue for over a year, turning CIA2 to disabled solved everything.
Now I can enjoy Portal 2’s great voice acting without having to enable subtitles and ruin the experience 😛

Wooden letters in the mailbox?

Monday, August 30th, 2010

So I opened our mailbox to find black painted wooden letters taking up the whole thing – An ‘M’, a ‘N’ and two ‘I’s.
Viral marketing or some random stunt? *wanders off to google*
