FBdev driver

SDL Development

Hello. I try to run SDL with S3 Savage framebuffer.

No luck (Unable to initialize SDL: No available video device). SDL is
compiled fith fbdev support (at least I hope so, I’ve tried emerge libsdl
with fbcon USE flag (gentoo) and also manual library compilation with
–enable-video-fbcon.
Frame buffer is running (/dev/fb exists, permissions ok, /proc/fb has device
name - I tried Savage FB and also Vesa FB).

Any ideas what to try/ what to do?

Btw. mplayer is running (-vo fbdev and fbdev2 also)

Thanks
Bu

Try running as root. The usual problem is permissions on the mouse and
keyboard devices. Also make sure you’re using SDL 1.2.10, there were a
bunch of fbcon fixes.

I tried 1.2.10 with --enable-video-fbcon and still the same problem. Running
under root. mplayer -vo fbdev2 works. with vesa framebuffer (not the default
one - s3savage), even mplayer -vo fbdev works. (/dev/fb0 has 777)

SDL never :frowning: I always get Unable to initialize SDL: No available video
device
I’ve tried to set SDL_VIDEODRIVER=fbcon or fbdev → nothing changes

I’m trying it with test/testvidinfo - which works under X for me.

Any idea please?On 5/24/06, Sam Lantinga wrote:

do a run under strace and try to see what happening…
$>strace ./testvidinfo 2>delme
$>less delme

When you resolve this problem I bet that your next problem will be
that savagefb doesn’t sync with your monitor properly.
