Various notes, sometimes quite rough, on issues I’ve had on the Raspberry Pi.
Blinking red power led ∞
This is a power issue. You might have a bad power supply, or perhaps your cabling isn’t connected solidly. Remove and re-insert things, several times if you must!
Sticking keys ∞
I had issues where typing would be inconsistent and would often “stick” and have keys repeat. Using the mouse was difficult too.
This turned out to be an issue with my mouse being plugged into my keyboard’s cheap hub. Plugging both my keyboard and mouse directly into my powered USB hub solved this issue.
It had nothing to do with my using a USB wireless dongle.
shift-2 gives ” instead of @ ∞
\sudo \raspbi-config
Internationalization options > Locale
I choose en_US.UTF-8
Internationalization options > Change keyboard layout
I chose my particular keyboard, but I suspect that a 104 would work well.
Restarting was not necessary.
other notes ∞
I did not test these.
either
\sudo \dpkg-reconfigure
Keyboard configuration, then restart.
or
/etc/default/keyboard

Wireless ∞
Wireless won’t work ∞
If the wireless GUI briefly shows:
Association request to the driver failed
This just means you typed the wireless password in wrong. Yes Linux, continue the tradition of mind-boggling error messages.
Wireless too slow or freezing ∞
Works fine with an crappy wireless dongle in one setup, but not another? Remember that the Raspberry Pi’s USB is under-powered. Use a powered USB hub.
I could reproduce this with a wireless dongle alone, versus a wireless dongle and a self-powered USB hard drive.
HDMI is not full screen ∞
edit /boot/config.txt and add/un-comment the line:
disable_overscan=1
.. then reboot
[unsolved] HDMI is too bright ∞
TODO – [partially solved] Raspbi boots into a GUI with no login prompt! ∞
I don’t know of a proper way to solve this.
\sudo \raspbi-config
I disabled the GUI. From the commandline, I do:
\sudo \lightdm
then I control-alt-1, control-z, fg, control-d (twice), control-f7
FIXME – this is a silly workaround..
