enable VGA output

[TranceTrouble]

once again running into a user problem,

i got myself a running kernel and i had it working with FrameBuffer support before but it stopped working, my old compiled kernel does still work but i cant seem to find out what is wrong in my new .config to get it working again. currently it doesn't display anything on my vga but i have console over uart.

does someone know which settings i need to set specifically to get it working again?

ah found my problem had to enable VGASTATE as well

Hi,

Taking advantage of your question, which required modules to enable VGA ouput?

[TranceTrouble]

i set the following modules located under: Device Drivers / Graphics Support

<M> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support
    <M> Mali DRM supprt
<M> ARM Mali GPU modules
<M> Lowlevel video output switch control
<*> Support for frame buffer devices -->
    <*> Enable Firmware EDID
    Display options for sun4i/sun5i --->
      <*> DISP Driver Support(sun5i)
      -*- Reserve memory block for sunxi/fb
      <*> Disable FB/UMP integration
      <*> LCD Driver support (sun5i)
[ * ] Backlight & LCD device support --->
   <M> Lowlevel LCD controls
   <M> Lowlevel Backlight controls
   <M> Generic (aka Sharp Corgi) Backlight Driver
Display device support --->
   <*> Display panel/monitor support
Console display drive support
   <*> Framebuffer Console support
   <*> Map the console to the primary display device
[ * ] Bootup Logo --->
[ * ]Standard black and white linux logo
[ * ]Standard 16-color linux logo
[ * ]Standard 224-color linux logo

i haven't tested this over the LCD connector yet, only through VGA.
hope this helps.

Thanks very much. Now, the question is which modules to load?
