**** BEGIN LOGGING AT Wed Apr 24 02:59:57 2019 Apr 24 11:20:10 <__ikki__> I'm not able to run gnuplot on my pc connected to BBBW via wifi. Getting error "QXcbConnection: Could not connect to display" Apr 24 11:22:45 <__ikki__> https://pastebin.com/4qjW3ZSW Apr 24 12:06:57 __ikki__: 1. why are you running gnuplot as root? 2. are you trying to have it display on the beaglebone or on your pc? Apr 24 12:12:24 <__ikki__> 1. because it touches sysfs files 2. on pc Apr 24 12:12:51 <__ikki__> 1. otherwise you get permission denied Apr 24 12:12:59 <__ikki__> zmatt: ^^ Apr 24 12:13:24 ehh what? what is it trying to access that gives permission denied on the debian account? Apr 24 12:14:08 the default account has access to nearly everything you might need in typical use of a BBB (apart from some system administration tasks like installing packages) Apr 24 12:14:31 and 2. use X11 forwarding (ssh -Y) Apr 24 12:15:05 <__ikki__> 1. nevermind. I agree with your argument[solved] Apr 24 12:15:35 <__ikki__> 2. you mean loging using ssh -Y ssh debian@192.168.8.1 ? Apr 24 12:15:43 <__ikki__> 2. you mean loging using ssh -Y debian@192.168.8.1 ? Apr 24 12:15:45 yeah Apr 24 12:15:59 <__ikki__> let me try and will get back to you in a moment. Apr 24 12:19:37 <__ikki__> zmatt: gives me "X11 forwarding request failed on channel 0" Apr 24 12:20:26 uhh, are you using linux, mac, or windows? Apr 24 12:20:43 <__ikki__> linux Apr 24 12:20:53 that's odd Apr 24 12:21:20 try -X instead of -Y Apr 24 12:21:33 <__ikki__> ok Apr 24 12:21:39 oh I got them mixed up in the first place Apr 24 12:21:42 it's -X you want Apr 24 12:22:24 <__ikki__> still getting the exact same error Apr 24 12:22:53 what does echo $DISPLAY say? Apr 24 12:23:28 <__ikki__> blank Apr 24 12:23:35 <__ikki__> nothing Apr 24 12:23:45 uhh what Apr 24 12:24:07 <__ikki__> it is empty Apr 24 12:24:24 what distro are you using? Apr 24 12:24:45 <__ikki__> debian on BBBW Apr 24 12:24:56 <__ikki__> ubuntu on pc Apr 24 12:25:09 no I mean on your pc, sorry (ditto for the "echo $DISPLAY") Apr 24 12:25:19 <__ikki__> on pc i get ":0" Apr 24 12:26:54 maybe xauth isn't installed on the bbb ? Apr 24 12:27:00 <__ikki__> do i need to install any packages on BBBW ? Apr 24 12:27:05 <__ikki__> ah Apr 24 12:27:34 <__ikki__> what packages should I install ? openssh-server, .. ? Apr 24 12:27:41 xauth Apr 24 12:28:03 it might need more, but it definitely needs xauth Apr 24 12:28:22 <__ikki__> installing... Apr 24 12:28:25 I checked by adding the -v option to ssh to enable debug logging and saw: debug1: Remote: No xauth program; cannot forward X11. Apr 24 12:32:20 <__ikki__> zmatt: Thank you so much!! Apr 24 12:32:29 <__ikki__> it was xauth indeed! Apr 24 12:48:39 <__ikki__> zmatt: FYI, echo $DISPLAY gives me "localhost:10.0" Apr 24 15:30:30 m Apr 24 19:08:38 Hi there, I have a question about powering the Beaglebone Black via the P9 header pins. I have been trying to use a hobbywing UBEC voltage regulator to give me five volts from a 3-cell lipo battery. This 5V I then applied to pins P9_5 and 6. The ground output from the voltage regulator went to pins P9_1 and 2. This worked but something just happened and I'm afraid that I fried my board... when I test the voltage regulator output with my Apr 24 19:09:26 I think this is technically outside of the Black's voltage tolerance. Do you think that would have killed it? Apr 24 19:19:20 your question got cut off Apr 24 19:19:28 "when I test the voltage regulator output with my" Apr 24 20:04:30 what an evil cliffhanger /o\ Apr 24 20:06:21 I do wonder what, if anything, might break before the overvoltage protection of the PMIC kicks in at 6V typ (5.8V min, 6.4V max) Apr 25 02:53:57 How can I use iframe in an html page from Youtube.com to produce some bbb related info. on my homepage? Apr 25 02:55:52 I thought since I went to this maker faire thing, I could brag a bit about my downfall. Apr 25 02:56:20 Do not worry. Apr 25 02:56:27 No harm, no foul. Apr 25 02:57:30 I went to w3schools.com to learn about iframe. Apr 25 02:57:50 I think that the iframe was not supposed to last. I am not sure yet. Apr 25 02:57:56 It just does not do anything. **** ENDING LOGGING AT Thu Apr 25 03:00:02 2019
