NOOBS V1.3.4 - Analogue Video

Fri Jan 17, 2014 9:21 pm

Hi All,

1st off, I've only tried this once so far and it could well be my setup but I am having problems with a NOOBS install when trying to do so through Analogue Video (RCA).

I can get the NOOBS install screen displaying (with the manual selection of the video mode via 1,2,3,4), however when it has installed and rebooted the display is not available. I installed Raspbian and the additional Home space option. I am able to reload and view NOOBS when booting with Shift, and looking at the card the partitions have been added etc.

Q: Does Raspbian auto-select the video on startup as it used to? Or does that now have to be explicitly set within the config file?

Thanks.

The NOOBS installer behaves differently to Raspbian, presuming HDMI and using that for (all) installed O.S.('s) unless told to use composite video "permanently". This is, perhaps, easiest to explain further by pointing you to the "installation process snapshots" (for composite video) within my webpages at: http://www.cpmspectrepi.webspace.virgin ... ellow.html . In effect, Raspbian's normal "auto-select" mode is "disabled" by NOOBS' auto-generated entries in a config.txt in Raspbian's /boot directory (which is not the directory NOOBS itself uses). However, said config.txt file (or any other associated with a different O.S.) can be edited via an editor provided via NOOBS' recovery mode: ww.cpmspectrepi.webspace.virginmedia.com/raspberry_pi/MoinMoinExport/NOOBSinstallV132.html#Monitor_Photographs_of_NOOBS_Recovery_.26_Editing_Tools
Trev.
NB. Although my "snapshots" are mainly for 1.3.2 they still apply to 1.3.4
Still running Raspbian Jessie on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W) but Stretch on my 2xP3A+, P3B+, P3B, B+, A+ and a B2. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

This appears to be causing some confusion. I have answered a few of these questions recently. Your screen shots are great. I particularly like the first one with your reflection Trevor :lol:

Thanks for the answers.
Re-doing it and it appears to have booted into raspi-config and is now displaying correctly on analogue video, I think what may have happened was that the "keep settings" dialogue didn't appear or I'd knocked the keyboard before seeing it.

Perhaps there needs to be a sanity check if the display option that will end up running on reboot doesn't match the current one. It is odd that it needs to be set really, since if you select to "keep" composite video it detects when you connect HDMI before power-up anyway.

I guess the default of HDMI only means it is more plug and play if using HDMI (not mattering if HDMI is connected after power-up) - but that is a pig if you are assuming you can plug into an analogue TV without changing anything (by that time it'd be too late). Not least since the settings aren't accessible from windows.

This was raised as issue #142 (https://github.com/raspberrypi/noobs/issues/142) by @rdb when it was first "flagged up" in an older thread. AFAICT it is now regarded as something to be addressed before the next major NOOBS release.

Didn't spot that, glad it will be covered. :)
