List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 27 Nov 2014 13:32:00 -0000 Hi, I posted to this list earlier this month and did not receive any input. I have an old tv with composite input and outputs, I thought this would be ideal for a low cost monitor for the RPi. I have been experiencing a problem in which the text is drawn past the bottom,top and sides. I have looked around quite a bit but cannot resolve the issue. Changes to the overscan_left, overscan_right, etc. in /boot/config.txt do not change the behavior. framebuffer_height and framebuffer_width settings do seem to change the behavior. The tv itself has controls for the picture and v-hold but no horizontal control. The rear of the tv has two set-screws which are labeled focus and screen (screen controls the brightness). I have seen mention of copying the firmware over, but have also seen that it seems that this is unnecessary. Unfortunately I have encountered issues with cards that I plug back into this machine after writing the image, so I cannot copy the firmware over. I would use putty or ssh, to log in and put that there but I have run into trouble there as well. I have enabled sshd, and set the hostname although I cannot seem to find the RPi on the network while using Ethernet cable (Cat 5e)... This is not surprising because I am novice with networking. I have also tried telnet, although I saw elsewhere on this list that one has to enable it. I have not found the place to do that, I looked in loader.conf and rc.conf. SO, I cannot report dmesg, netstat or other output because I cannot ssh into the machine. I have the intention of running a simple boa webserver serving a commercial portfolio website. Thanks, -
