Barand Posted November 14, 2018 Share Posted November 14, 2018 I once got a call-out from a client who was having a problem printing his spreadsheet. When I got there I switched on his printer and it worked great after that. Is your screen switched on?

dil_bert Posted November 14, 2018 Author Share Posted November 14, 2018 hello dear Barand, found an very very interesting thread: see https://www.raspberrypi.org/forums/viewtopic.php?t=34061 presume, you have installed your selected OS on SD card. Boot sector of the SD card is normally accessible from Windows, so you can edit file config.txt. What you maybe need? Add into config.txt this line: Code: Select all hdmi_force_hotplug=1 well - this can be a good hint..

dil_bert Posted November 14, 2018 Author Share Posted November 14, 2018 btw found some additonal texts: https://raspberrypi.stackexchange.com/questions/2169/how-do-i-force-the-raspberry-pi-to-turn-on-hdmi Add these two lines to /boot/config.txt and reboot Raspbmc: hdmi_force_hotplug=1 hdmi_drive=2 hdmi_force_hotplug=1 sets the Raspbmc to use HDMI mode even if no HDMI monitor is detected. hdmi_drive=2 sets the Raspbmc to normal HDMI mode (Sound will be sent if supported and enabled). Without this line, the Raspbmc would switch to DVI (with no audio) mode by default. config.txt is read by the GPU so it will work on every distro. There's two ways to do it. In older Pi installs, use the fb0 framebuffer when you want to display stuff on the HDMI/TV display, for example: FRAMEBUFFER=/dev/fb0 startx will use the HDMI/TV framebuffer for X windows instead of the PiTFT On Jessie Pi installs, run sudo nano /usr/share/X11/xorg.conf.d/99-fbdev.conf to edit the configuration file and make sure it contains: Copy Code Section "Device" Identifier "display" Driver "fbdev" Option "fbdev" "/dev/fb0" EndSection change the Option "fbdev" "/dev/fb0" line to Option "fbdev" "/dev/fb1" if you want the xdisplay on the PiTFT or fb1 to fb0 for HDMI output.Update: If don't see the code above in the file, then simply copy and paste what is shown in this answer at the bottom of that file. If you can't find 99-fbdev.conf file in that folder, then there is probably another file with different name like 10-evdev.conf in the same folder which you will have to modify to make it work as described above. welll i did deeper into this issues Quote Link to comment https://forums.phpfreaks.com/topic/307899-banana-pi-i-have-connected-all-the-wires-no-signal/#findComment-1562144 Share on other sites More sharing options...
