Re: Painfully Slow Browser

I also tried installing netsurf-fb, but upon launching, I just get a blank screen:

netsurf-fb http://some.website.com

Are there other dependencies or is the command line wrong ??

Painfully Slow Browser

I've tried iceweasel (firefox), Chromium, dilo and finally settles on midori, which seems to have the least cpu and memory usage and appears to be the most lightweight. I am using the browser in full screen, kiosk mod running directly from openbox (no lxde), there's no plugins tabs, or anything else...

Thanks, will try that.

I added a cron job @boot to root user to solve the immediate problem.

Re: Broken CGIHTTPServer ?

This was tested using the ROOT user, if I run it as PI user then it works.

Is there some reason that CGIHTTPServer cannot be run as root ??

@jojopi - Thanks and my apologies for the delay, I thought that I had subscribed to email alerts when a thread was updated but it appears not and I thought nobody had responded.

Re: Setting up HDMI output

No, the HDMI is completely controlled by the GPU. There is no code in the kernel (or anywhere on the ARM side) that can program arbitrary HDMI timings. As explained earlier, waiting for GTF support to be added by our HDMI guy is the only possible solution. Ahh, that's such a shame, I have spent soo...
