Does anyone use an Analogue TV in X Windows?

Only I find the text hard to read. If anyone does, what settings did you use?

Re: Analogue TV flicker

Re: Analogue TV flicker

Many thanks for the suggestion, is there any control over interlace settings?

The games that reboot to run like Iridium rising and Open Arena look fantastic and flicker free.

Kind regards

Analogue TV flicker

Is there a fix for analogue television flicker, particularly after starting X windows, only it does hurt the eyes?

I can't see any sdtv_ options that look like they would help, and wondered how to fiddle with things like interlacing?

Kind regards

Re: Connecting stepper motor to Raspberry pi

the stepper motor im looking at is http://uk.rs-online.com/web/p/stepper-motors/1918384/ and the solar panel is really small. This is only really for a working model at the moment so the easiest way to connect them would be using a motor control board? any recommendations? (thanks for feedback :) )...

Re: Looking for Stepper Motor information

As far as I know most motors in printers are stepper motors, probably bipolar.

There is information on driving them about as well. Printers are also a source of things like cogs and belts.

Re: No HDMI output when powered?

Can you remove the HDMI mode line from config.txt and perhaps just have config.txt containing information on what can be set or a reference to an online manual? All I did to actually boot was put # in front of all lines and that did work but should also work "out of the box" or else people will just...

Re: No HDMI output when powered?

Where is the page on the wiki which tells me what could or indeed should be in config.txt?

I don't get any HDMI output either, I suspect because the config.txt sets an HDMI mode that my monitor doesn't support.

Re: Gentoo Arm on Rasbpberry Pi (hard float)

My understanding is that, at the moment blob differences are making massive differences (positive) that have impacted on the way kernels are built to be stable. It would be useful if there was a mailing list for distro developers.

Re: config.txt

Dom, firstly well done, and thankyou very much for this.

Is it possible to turn off the GPU in part for headless mode, giving more RAM to the CPU.

I presume we will not be able to use raw GPU power for normal programs.
