I just brought a raspberry pi 3 with the noobs card with pre installed raspbian l, however when I turned power the download option menu didn’t appear but instead just run. Eventually getting to the home screen.
Main question, how do I know raspbian is installed? And why would the download menu not appear?
Any help would be great as I am new with raspberry pi.
Thanks heaps.
Hold SHIFT while booting. Download menu should show.

I have a problem with OBS. I'd like to make tutorials how to do programming, teach people basics & show them, for example, how to write neural network in Java (without any ML libraries) but in order to do so, it would be great to show them my presentation about it and other windows, so recording full screen is needed (I know I could keep switching windows but it's faster and easier to display full screen). When I added the source "capture screen" the captured screen is black but audio works. I've tried to solve this problem and I went through many tutorials (like 15 or smth) and nothing has helped. I've also added a new thread in OBS Official Forum but nobody has responded. My OBS version is 25.0.4. Here is what I've tried:
- I ran the program as an administrator
- I have reinstalled it (with deleting all files and settings ~ no leftovers)
- In Nvidia Control Panel in 3D Settings I've selected OBS Studio and changed graphic processor to an integrated graphic (also tried dedicated graphic and global choice - nothing worked)
- In GForce Experience I disabled sharing
- Couple times I've restarted the computer and OBS (after any change I've done)
- I ran the OBS in compatibility mode with Windows 8 (and I've tried Windows build-in troubleshooting option)
- I ran OBS with an integrated graphic from a desktop
What I've discovered is the capturing specific window works perfectly, the problem occurs only with capturing full screen.
I have no idea what to do, please help me.
Here is what I see:
It looks like OBS just "can't see" screen, I use only one screen by the way
Black screen
though single-window capturing works perfectly

Specifications of my computer:
I use a laptop - MSI GF 63 8RC

You will need to change the Graphic for this app to integrated graphic
I had the same problem in the virtual machine And I solved it this way go to virtual machine setting
in display section uncheck Accelerate 3D graphics
The problem was solved and the recording was done correctly.
My intuition tells me someone, somewhere, must have answered this question before. Searching around I have not found it.
I have a freshly installed Windows 7 box (upgraded to Windows 10 to get the machine made eligible, now reinstalling). I have a cheap wifi dongle. I do not know the manufacturer, nor where the driver dvd is. Plugged into the machine running Linux, it just works. It is small, black, and has 802.11n printed on it in white writing, and there are no other identifying markers. (For reference, it looks a bit like one of these: http://www.dhgate.com/product/1pcs-mini-usb-wifi-adapter-802-11-b-g-n-wi/250459680.html)
How, in general, in Windows 7, do I identify the correct driver, and how to I obtain the correct driver?
Found it, ironically shortly after posting this question in frustration.
Go to Windows Device Manager (right click on Computer in start menu, select Properties, then select Device Manager on left pane).
Find the device in Other Devices, then select Properties
Go to details pane, select Hardware Ids from the property dropdown.
You will see, e.g. USB\VID_148F&PID_5370&REV_0101 -- take this string and put it into google, or another search engine.
That gives you a good chance of finding something. I found a .cab file via devid.info, copied it to the machine, extracted all the files to a folder, then in the Device Manager right click on the unknown device, click Update Driver Software, select the option to browse your machine, and point it to the folder you unpacked the drivers to.
I want to get the hang of developing on the Nao robot but without having the actual robot yet (I will get it later). So I installed the software at home but I cannot see any robot at the Robot View of Choregraphe.
Just installed Choregraphe Suite 2.1.0.19-vs2010 and also Downloaded and Extracted naoqi sdk 2.1.0.19-vs2010.
I followed the instructions:
Choregraphe started
naoqi also started via cmd
naoqi attached to Choregraphe
But still no virtual robot to be seen at my Robot View tab in Choregraph.
You should try to use the Virtual Robot.
In choregraphe menu, click the Connection/Connect to Virtual Robot
We have several TVs, each with a Raspberry Pi hooked up, so they can be used as information dashboards. The current setup stays on one tab the entire time.
I am trying to set it up so that it will automatically rotate through the chromium tabs every 15 seconds, but am not sure how to approach this.
The Pi's, as far as I know, only have a headless OS with chromium installed, which is started on boot in the xinitrc file.
I know there are some chrome plugins that can do this, but I don't think they can be installed on the command line.
Any advice would be appreciated
You can use xdotool with watch to do this:
# rotate tabs after 30 seconds.
watch -n30 "xdotool search --onlyvisible --class chromium key ctrl+Tab"
I toggled into full screen mode on QGIS 2.2 on my Mac, and now the menu bar won't show and I can't toggle out of it. From the documentation, it looks like it should toggle with F11, but it's not working. I've seen people having similar trouble on Ubuntu and Windows 7, but nothing for OSX. Any ideas? I appreciate it.
Just spent close to an hour with this problem- QGIS 2.2 on mavericks. Really vexing! I tried reinstalling (after trashing the previous version as instructed in the install notes), tried removing the hidden .qgis2 folder in the home directory, tried disabling all spaces on the machine (I started with 8 desktops), tried all permutations of Apple-F, ctrl-F, apple-shift-F, etc...
Finally, and simply, the answer was this:
F11 is documented as the toggle key, but in my mostly stock setup this was bound in MissionControl to 'display the desktop'. I rebound that function to F1, and then with QGIS up, hit F11 (on my MBP I need to also hold the fn key otherwise it's 'volume down') and I was out of Full screen mode.
Hope it works for you!
