You cannot find the documentation about the SensoriMotorLab on http://docs.sensorimotorlab.com anymore. For documentation on the vBOT RobotLab, please visit https://gitlab.socsci.ru.nl/sensorimotorlab/RobotLab.
Some cheat sheet instructions for the sled lab:
Using the experiment control computer
The computer under the desk is called vnc. It is connected to the three screens in front of you. To run an experiment you log on to the experiment control computer (control)
ssh -X control
By default windows are opened on vnc, not on control. If you want to change this, then type on control
export DISPLAY=':0'
Starting the sled server and service
After restarting the sled server (which is practically never necessary) you also have to restart the sled service. Log on to the sled server
ssh sled
and type
sudo service sled start
This will start the standard version of the sled server.
If you want the version of the sled server with smoother sinusoid ramp-up. Please go here. This most likely not necessary for you.
Using video modes not available according to EDID
Normally the monitor tells the computer what its supported combinations of resolution and refresh rates (video modes) are. This system is called EDID. If for some reason you want to use a mode that is not in the list of EDID modes, you have to add it yourself. This is typically the case if you use an analog connections to the monitor.
Before adding a mode you have to allow it in /etc/X11/xorg.conf (this file may not exist yet), the crux is in the line containing AllowNonEdidModes:
Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Idek Iiyama HM903DADTA" HorizSync 30.0 - 133.0 VertRefresh 50.0 - 200.0 Option "DPMS" EndSection
Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 770" Option "ModeValidation" "AllowNonEdidModes" EndSection
To add a 144 Hz 1024x768 mode do the following:
xrandr --newmode "1024x768_144.00" 169.30 1024 1104 1216 1408 768 769 772 835 -HSync +Vsync xrandr --addmode DVI-I-0 1024x768_144.00 xrandr --output DVI-I-0 --mode 1024x768_144.00
