For a simple one window / one application environment, install matchbox-window-manager. Create a small script file in your home folder: #!/bin/sh matchbox-window-manager & yourapp Ma...

Re: Run Processing Sketch without Startx

I am running on Oracle Java but still its too damn slow to run a rotating matrix.

Try to run ControlP5Matrix on your raspberry pi and tell me if its slow or not.

Re: Raspberry Pi Boots but No Display on AOC

UPDATE: I finally manage to make the display work and tested the touchscreen feature everything worked! The fix: Set the AOC's source from AUTO to HDMI 1 or HDMI 2 ( Thanks to Trevor for this idea ) Set the AOC's display from 16:9 to AUTO ( I think this is causing one of the problems ) config.txt co...

Re: Raspberry Pi Boots but No Display on AOC

W.r.t. the display having two HDMI ports - even if they're both input ports the display may have to be switched to the correct port before the Pi is powered up (and, possibly, with nothing else** connected to the other port). Trev. ** that might "demand" use of the display. I understand what you ar...

A "touchscreen" is not necessarily the "same" as a "standard" monitor - whilst the video link to the "other user's working system" does show that it can be made to work it was not clear to me how "exactly" it was connected to the Pi eg. was something more than "just" an HDMI connection needed, ...

Bad news, I tried a new HDMI cable this time a standard one. I was using a Flat High Speed HDMI with Ethernet and still no display.

I've tried tvservice on this new cable and it still recognises the screen as

There was a setting in config.txt (note that was way back using the Wheezy image) that forced the RPi to make HDMI the prefered start. ;) Isn't that what hdmi_force_hotplug=1 which he has already tried does? yes that should be fine I'd remove all the other ones and get it to boot then ssh in and ha...
