This file should contain the following lines to make |
|
20 |
your joystick work and avoid crashes: |
|
21 |
------------------------ |
|
22 |
disable-module=joystick |
|
23 |
disable-module=cle266 |
|
24 |
disable-module=cyber5k |
|
25 |
no-linux-input-grab |
|
26 |
------------------------ |
|
27 |
||
28 |
To disable to use x11 backend when DISPLAY variable is found use |
|
29 |
||
30 |
export SDL_DIRECTFB_X11_CHECK=0 |
|
31 |
||
32 |
To disable the use of linux input devices, i.e. multimice/multikeyboard support, |
|
33 |
use |
|
34 |
||
35 |
export SDL_DIRECTFB_LINUX_INPUT=0 |
|
36 |
||
37 |
To use hardware accelerated YUV-overlays for YUV-textures, use: |
|
38 |
||
39 |
export SDL_DIRECTFB_YUV_DIRECT=1 |
|
40 |
||
41 |
This is disabled by default. It will only support one |
|
42 |
YUV texture, namely the first. Every other YUV texture will be |
|
43 |
rendered in software. |
|
44 |
||
45 |
In addition, you may use (directfb-1.2.x) |
|
46 |
||
47 |
export SDL_DIRECTFB_YUV_UNDERLAY=1 |
|
48 |
||
49 |
to make the YUV texture an underlay. This will make the cursor to |
|
50 |
be shown. |
|
51 |
||
52 |
Simple Window Manager |
|
53 |
===================== |
|
54 |
||
55 |
The driver has support for a very, very basic window manager you may |
|
56 |
want to use when running with "wm=default". Use |
|
57 |
||
58 |
export SDL_DIRECTFB_WM=1 |
|
59 |
||
60 |
to enable basic window borders. In order to have the window title rendered, |
|
61 |
you need to have the following font installed: |
|
62 |
||
63 |
/usr/share/fonts/truetype/freefont/FreeSans.ttf |
|
64 |
||
65 |
OpenGL Support |
|
66 |
============== |
|
67 |
||
68 |
The following instructions will give you *software* OpenGL. However this |
|
69 |
works at least on all directfb supported platforms. |
|
70 |
||
71 |
As of this writing 20100802 you need to pull Mesa from git and do the following: |
|
72 |
||
73 |
------------------------ |
|
74 |
git clone git://anongit.freedesktop.org/git/mesa/mesa |
|
75 |
cd mesa |
|
76 |
git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a |
|
77 |
------------------------ |
|
78 |
||
79 |
Edit configs/linux-directfb so that the Directories-section looks like |
|
80 |
------------------------ |
|
81 |
# Directories |
|
82 |
SRC_DIRS = mesa glu |
|
83 |
GLU_DIRS = sgi |
|
84 |
DRIVER_DIRS = directfb |
|
85 |
PROGRAM_DIRS = |
|
86 |
------------------------ |
|
87 |
||
88 |
make linux-directfb |
|
89 |
make |
|
90 |
||
91 |
echo Installing - please enter sudo pw. |
|
92 |
||
93 |
sudo make install INSTALL_DIR=/usr/local/dfb_GL |
|
94 |
cd src/mesa/drivers/directfb |
|
95 |
make |
|
96 |
sudo make install INSTALL_DIR=/usr/local/dfb_GL |
|
97 |
------------------------ |
|
98 |
||
99 |
To run the SDL - testprograms: |
|
100 |
||
101 |
export SDL_VIDEODRIVER=directfb |
|
102 |
export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib |
|
103 |
export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7 |
|
104 |

105 |
./testgl |
