Re: Dispmanx VNC Server

Should work with all resolutions. 16bit is only transport layer.
Dispmanx is saving snapshots to 16bit RGB (RGB565) and then VNC is setup to use RGB555. So only shifts in VNC server can be problem.

Dispmanx VNC Server

Hello. I have been playing with dispmanx_snashot and using LibVNCServer and created a simple VNC server. It takes snapshots from screen via dispmanx and sends them via VNC. It can also view the 3D demos from hello_pi. The code is here: https://docs.google.com/file/d/0B0ImsXFDXpRBYkthTHMzWlRQUWc/edit...

When will be weston in repos

Hello

I am interested in Wayland/Weston. I am looking in raspbian repositories and can't find weston. Wayland is there, but weston not.
I know that weston now has raspberry pi backend so I want to try.

I am doing something wrong?

But when I snapshot it with dispmanx_snapshot I get the full resolution of TV and it is 720x480. The screenshot were taken in 10s distance. So first I saved dispman...

Combine OpenVG with OpenGLES2

Hello.

I am planning to do some kind of window manager and I plan to combine OpenVG and OpenGLES2.
My idea is to render OpenVG commands to OpenGL texture and display this texture with EGL/dispmanx.

Does someone knows an example of this. Is this possible to do?

Re: tvservice vs fbset ? Who's right ?

I think they are both right. If you have black borders around text try disable_overscan=1 in config. Then tvservice and fbset should report the same. I think this is all about overscan.

Re: HDMI/ TV out and framebuffer size. Text is not crystal c

Hello.

I am stuck. On my LCD monitor the disable_overscan=1 makes my command line moved to left and bottom and I can't see login prompt.

Can disable_overscan=0 and overscan_left be combined?
But also with disable_overscan=1 the text console is not "crystal" clear.

Any ideas?
Thanks.
