No don't do that. Somebody on here may very well know the answer. I can tell you how to do it if you are willing to re-install. If you do want to ask on another site, then Askubuntu.com is the place. Note it is not a forum - strict questions and answers only. If you could tell me how to do that I w...

If I run raspbain wifi works fine. After in...

Solved: Wrong default keyboard on boot - gentoo 64-bit

I had to change the XkbLayout option in /etc/X11/xorg.conf.d/00-keyboard.conf from "gb" to "us" in order to solve this.

SOLVED: disable autologin gentoo 64-bit

Hi, I found what I wanted in the GitHub notes by sakaki. I don't know how I missed it. The mail spool warning may safely be ignored. Also, if you want your new user to be automatically logged in on boot (as demouser was), substitute your new username for demouser in the file /etc/lightdm/lightdm.con...

Wrong default keyboard on boot - gentoo 64-bit

Hi, I can't seem to get a "US" keyboard recognized as such at the login prompt. Once I'm logged in it is set up correctly. I though if I wrote keymap="us" in /etc/conf.d/keymaps and then rebooted this would work, but it doesn't. Any suggestions on how to fix this are greatly appreciated. Thanks, Randy

The problem does not seem to be speed related. As far as I can tell screen does not have a file transfer capability.

Re: Using Dave Welch's bootloader07

Well I've determined that the problem is minicom. I'm using a Mac and I installed minicom using brew. File transfer simply does not work! When I use minicom on linux everything works fine.

Re: Using Dave Welch's bootloader07

I'm sure I'm just doing something wrong in minicom when I try to send the hex file. I left minicom running and used cat to select the file and redirected the output from cat to the port opened by minicom and the program loaded via the boot loader and is running fine. I'd really like to figure why I ...

It appears that putting the post-up iwconfig wlan0 power off command in /etc/network/interfaces works for me.
