Re: Pi dual screen

I assume that the framebuffer app needs to be running prior to starting x? If so, I think I would most likely set it up in cron. I am fairly competent in *nix, however I do realize that as this is a different architecture many of the usual conveniences are not available lol. Once I get the setup run...

Re: Pi dual screen

Would it not be easier to determine the pixel count myself by setting the desired resolution? In almost all cases you don't have to set the resolution yourself. The X server is smart enough to figure out what the connected monitors are capable of and sets the optimum resolution. Then, it's just a m...

Re: Pi dual screen

Yes, the touch function works. When using two monitors, you have to transform the touch area, though. By default the touch panel maps itself to the entire screen area - both monitors. E.g. in my PiTFT set-up, when I touch the upper right corner of the touchscreen, the cursor moves to the upper righ...

Re: Pi dual screen

I think you can simply startx a second time and specify frame buffer fb1 and you will get X on the SPI display. You need the fbtft driver installed of course. The CPU does all the graphics work on SPI in this case. What questions did you have? If I understand you correctly, this then means that the...

Pi dual screen

Ok. I just got a pi. I am somewhat literate in *nix, but by no means an expert. My goal, is to run a small touch screen on either dsi or the spi, and a monitor on the hdmi. After searching, I stumbled upon http://www.raspberrypi.org/forums/viewtopic.php?f=44&t=91764 which appeared promising, however...
