Support for: 7″ Touchscreen Monitor for Raspberry Pi

Hi Frank,

Yes, actually, that was I did the very first time after read your post.

I am just doing it again right now. My /root/.xinitrc file looks exactly like yours, but after reboot and waited for at least 5 minutes, I only saw a console with login prompt, as shown below:

I guess xinput_calibrator probably met the same problem ('can not connect to X server') as I ran it in the console.

Hi flipphos,

i tried this again with the latest version "RuneAudio_rpi2_rp3_0.4-beta_20160321_2GB.img" and it works like it should.

From your picture i believe that "local browser" is not enabled from the settings page.

Hi Frank,

Your idea worked. I saw the calibration interface and I did the calibration. After clicking the center of four designated crosses (precisely with tip of tooth picker), the screen went blank. I entered SSH, revert the /root/.xinitrc file to normal, ran "sync" then "reboot". I hope this is the right procedure to perform. Or did I miss something?

However, I didn't feel the touch screen was correctly calibrated when I started to touch around to verify after the reboot. At least one axis is upside down. As shown in the photo below, when I touch the right up area marked with orange color, the screen responses in the down right area marked red. This looks odd, as the response is distorted, and not only reversed. Besides, I could never hit the "play" button in the middle-top.

Frank, could you point me out where the calibration data is stored, so I can make a backup when the time is right.

Another cosmetic issue is that when the local browser starts, the bar with 7 icons (shuffle and volume controls, etc.) is in overlap with the bottom menu bar, bearing "Library", "Playback" and "Queue". Please compare the photo below with the one above to see what I mean.

Last bar is in overlap with the bottom buttons.

I had to scroll down to reach the bar with the 7 icons.

Just for fun, I caught the "play" button, finally.
When I touch the orange spot, that means 'play'.

Play button found.

Hi Frank,

I agree with you that my screen could be of problem on resolution, given the distortion between touching and responding. The distortion might be introduced by my workaround, which twists the screen ratio to some factor we never know. Therefore I am thinking to pick an official Rpi touch screen once.

I got this screen as a second hand one because of cheap price (25$), I was told the resolution was 800x480. I didn't find any brand or name on it, only some stickers as shown below:

stickers on the back.

At least I can confirm to other users that the xinput-calibrator works. :p

Cheers,

I downloaded and install the latest image -RuneAudio_rpi_0.3-beta_20141029_2GB and things were working fine. I then went and upgraded the kernal and firmware by running the command pacman -Sy --force raspberrypi-firmware-bootloader linux-raspberrypi

Upon reboot I have no audio output interface. How do I get it back. I was just using the analog output on the raspberry pi itself. I am using a RaspberryPi 2

Thanks
