i have a 7 inch LCD and connect it to my PC via HDMI but when i try to launch a program from the Pi it just show a blank screen on my monitor. I am using the Raspbian OS and the build in LCD support but i want to use my LCD with my PC. I have tried all the different drivers and even the RasPIAN image but nothing is working. I have also tried following the instructions on the raspberry site. Even though i have followed the instructions on the raspberry site and installed all the necessary drivers and drivers the LCD is still a blank screen when i connect the HDMI cable from my PC to my Pi and try to launch a program. does anyone know how to use the keyboard and mouse on your 7 inch LCD with Raspberry Pi?
I have a 7 inch LCD which I am using with a Raspbian distro (I downloaded the latest Raspbian). I've got the libatasmart drivers, screen size set, and some other parameters set as well, but it still doesn't work. I'm sure I'm missing something, but I can't figure out what it is.
I was also having difficulty getting the touch screen to work. If you are having problems, you should try removing xorg-x11-server-fbdev libfb1 libfbclient0 libxcb1 libxcb-shape0 libxcb-keysyms1 libxcb-randr0 libxcb-render0. This won't work. If you try to remove these packages, you will get an error message saying they are being kept back. So just leave them alone. The touchscreen did not work if I attempted to remove them. I then installed the touch drivers using sudo apt-get install.
The second problem that I found with the touch screen is when watching HD videos. It will freeze and I'll have to do the touch workaround to get it to turn off. The current workaround is to unplug the HDMI cable from the Pi. I found that if I left the HDMI cable connected, it wouldn't freeze. However, there was no response from the Pi when using the touch screen.
I've also noticed that the screen will be black for a short period of time at the beginning of the boot. I haven't been able to determine why, however, it seems to happen when using the FBTFT drivers. It's fixed by doing: raspi-config again, and selecting the video settings, default, and reboot.
This didn't work. I then did a su and apt-get purge again, and the same thing happened. It wasn't until I did a su and apt-get install that it worked. I then rebooted and the touch was working.
Hi, I tried again and had no luck. I have a WaveShare 7 inch LCD from Waveshare that I want to hook up and use with the Raspbian Raspberry Pi operating system. I've followed the steps in the tutorial here: http://www.makeuseof.com/tag/install-and-configure-linux-kernel-module-raspberry-pi/ but it doesn't work. I'm using the latest version of Raspbian with NOOBS installed and the driver versions are: Linux kernel version: 3.12.8, 4.0.4 kernel modules: 6.6, 7.0.2. When I plug the screen in nothing happens. I can connect it to the Pi but the screen doesn't work. Any suggestions? 827ec27edc
