Fbcon linux support problem

Good evening!

I’m working with fbcon SDL support, and I’m getting an strange error: the video output look likes darker.
I tryed with a RivaTNT2 an ATI Radeon 9250 (each one with the corresponding framebuffer driver) and I got
the same picture. It’s very strange because at console screen, it’s normal.

I tryed with the vesafb driver and works great, but of course, without changing resolution.

If you like, I can provide some pictures.

Please someone start discuss this with me!

Hello !

Have you tried this with all depths ?
8, 16, 24, 32 bit depth ?

Thanks for reply!

I tried with different depths and I got the same problem. I switched to
another videocard (Riva TNT2) and I got the same result.
Probabily it’s a SDL bug.

I tried another program called AdvanceMENU, and this program works with
framebuffer directly. I got a normal
picture with it.

Do you know if this bug can be fixed?

Thanks in advice!

Please make a screenshot/photo of it and post it here.

Dear Torsten Giebl,
now you can see how image is darker (of course this is not a monitor
problem/adjustment, as I mentioned):
