Hi,

Thanks for the fast response. I tried another wireless network and it is fine?! Very odd? My PC and other devices can connect to it just fine and in turn see the server connected etc. I will try taking a look at the router today to see what about it the pi doesn't like but for now i can see the wifi being stable and keeping an eye on it now.

thanks

Nick

I am a bit disappointed with the Raspbian Jessie with Pixel release, I've got it running on my Raspberry Pi Model B+. However, I'm stuck with "wlan0: not associated" issue, so it does not detect and activate my WiFi adapter. Having to run a lan cable across the floor to my router in order to access the internet. Was not having this issue with my OSMC installation on the same machine, that works fine with my WiFi adapter.

Odd, working fine here.

Go to a terminal, and type "dmesg | tail" just after trying to associate. Any applicable error messages? My guess would be a authentication issue.

Might be worth starting a new thread for help.

No worries, I'll just junk it and go back to OSMC, it's obviously not yet ready for release

The question is, what WiFi adaptor is it, Raspian doesn't have all drivers there. Spin out a help post, it may help others as well or already have a solution they could spin into Raspian.
That or it could actually be Pixel at fault and needs fixing.

Interestingly the keyboard layout cannot be changed with latest 10.4.2017 release.

Clicking the button doesn't open any menus or whatnot. Same phenomenon if I try it from new "Raspberrypi configuration" -> "Localisation" -> "Set keyboard". Other buttons seem to work and one can change the locale so via that way you can get correct keyboard setup. However then also the whole language changes which is a bit annoying.

Just tested this again on a clean install and it's working well. Do you have lxkeymap installed? Are you able to change the layout using lxkeymap? Is the button in rc_gui greyed out?

I have the same issue. The button is not greyed out, unless click is held but does not load the lxkeymap window. I am also unable to load the lxkeymap desktop application from the applications menu.

The applications menu is pointing to the correct file. When I examine the lxkeymap properties (/usr/bin/lxkeymap) it shows that it is a python3 (IDLE). It will load as code (under glade) but will not execute.

This has all come about from a Pixel upgrade which rendered my keyboard in opperable (although it is the same one I have used on all my Pi's), and yes
* i have swapped through 3 different keyboards (all ok according to http://elinux.org/RPi_USB_Keyboards) Chicony USB, Genius, logitech k120)
* lsusb shows that the keyboard is recognised
* /proc/bus/input/device shows the keyboard
* the power supply is 5V 2.5A (Maplin) - yes I have tried others - note the Chicony keyboard only needs 50mA
* I have reinstalled pixel (sudo apt-get install --reinstall)

Loathed to start again as I have opencv complied with python3 and a clean install can take upto 8 hours to compile correctly.

Can you run "lxkeymap" from a terminal window? Do you get any error messages when you do so?

When the newly installed image boots, opening any app from the few that are in the top panel; they are locked to screen top left. The "decoration" bar cannot be accessed.

I sometimes move windows using just the keyboard but that's impossible, & I can't see the keyboard pref's.

So, open lxterninal

$ lxkeymap
Bus error

It sounds to me as if there is a problem with your SD card - bus errors tend to be associated with things like the card being full, or otherwise corrupt in some way.

It's worth trying to see if your card is full, and deleting some files if it is.

Hi spl23,

If I run lxkeymap from xterminal i get

/user/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:57: gtkwarning: could not open display
Warnings.warn(str(e), _gtk.warning)
Trace back (most recent call last):
File "/user/bin/lxkeymap", line 707, in <module>
Engine = xklavier.engine(display)
Type error: must be a gobject.GObject, not none

I assume that this is because gtk has to be used in a window environment rather than terminal.

If I run /user/bin/lxkeymap using a folder window then it opens the python code, and does not run with Python 3. I have changed the associated Python from 3 to 2.7 and it gets further this time with an error
warning (from warnings module):
File "/usr/lib/python2.7/dist-packages/lxkeymap/helpers.py"' line 46

So if I can read the above correctly I need to set a default path...where?... /home/pi/.config/lxkeymap.cfg ?

No, lxkeymap will run quite happily from a terminal window as long as there is a desktop environment running - I've just checked it here. This is exactly the message I see when I try to run lxkeymap when booted to the CLI rather than the desktop. You are trying to run it from the PIXEL desktop and not from a Raspbian Lite image, aren't you?

Those messages are all as expected. It is designed to run under Python 2, so you will need to make sure /usr/bin/python is Python 2 not 3.

As above - this looks like something wrong with your desktop environment; something somewhere is missing.

Is PIXEL dead? The link referenced on the Introducing PIXEL page in "The Raspbian + PIXEL image is available from the Downloads page on our website" statement no longer shows a download for PIXEL.

It has just been renamed to Raspberry Pi Desktop (RPD)

Thanks for responding.

But I don't see a Raspberry Pi Desktop download link on the Downloads page either.
