SDL_config.h is no longer in CVS. Instead, configure will generate it for
systems that use configure, and we always copy SDL_config.h.default to
SDL_config.h before generating a snapshot or release archive.
Also fixed a couple of uninstall issues.

Subject: [SDL] Frame Buffer patches...
Okay I'm new at patch generation - so please tell me if there's a better way
I could have done this.
Attached are two patch files generated with 'cvs diff -u'
SDL-fb-open-lock.patch applies to SDL_fbvideo.c
Modifies the open loop to check /dev/fb/0 found on devfs...
Modifies the lock code to return failure if the current virtual terminal
is not the one opened for frame buffer writing...
Lock would hang forever if switched away (ctrl-alt-F1) ...
SDL-fb-mousedrv-screensave.patch applies to SDL_fbevents.c
Switches default mouse mode based on SDL_MOUSEDRV - currently only
accepts PS2 - otherwise default is MS Mouse.
When the screen is switched - exisiting code (wrapped in ifdef
SAVE_SCREEN_COTENTS) would save the wrong bit of the screen....
( I run frame buffer 1600x1200, the size I requested was 800x600 - the
save would save the top 800 lines (non biased) and restore them... Adding
screen->offset fixed that )
However, if that option is not set, then a call to SDL_UpdateRect (full
screen) is made. (which may have had it's contents changed since the screen
is not entirely locked because of lock-failure patch)

Subject: [SDL] Re: Trigger mouse wheel event -- not in X-environment
I have looked into the codes for the IMPS/2 mouse wheel mode of fbcon driver.
But I found something weird.
Here's the original codes to set a mouse device into IMPS/2 mode in libSDL.
In the file src/video/fbcon/SDL_fbevents.c
In function static int set_imps2_mode(int fd)
...
Uint8 set_imps2[] = {0xf3, 200, 0xf3, 100, 0xf3, 80};
Uint8 reset = 0xff;
fd_set fdset;
struct timeval tv;
int retval = 0;
// Set mouse device fd into IMPS/2 mode
if ( write(fd, &set_imps2, sizeof(set_imps2)) == sizeof(set_imps2) ) {
// ??? then RESET it..???
if (write(fd, &reset, sizeof (reset)) == sizeof (reset) ) {
retval = 1;
}
}
...........
Since it sets IMPS/2 mode then reset it, so you will never get a mouse into
IMPS/2 mode to use its wheel.
What I did to make the wheel usable is remove the RESET codes.
....
if ( write(fd, &set_imps2, sizeof(set_imps2)) == sizeof(set_imps2) ) {
/*
if (write(fd, &reset, sizeof (reset)) == sizeof (reset) ) {
}
*/
retval = 1;
}
....
And in FB_OpenMouse(_THIS)
Make the device /dev/psaux to be setted into imps2 mode such that it can be
detected its a imps/2 mouse or not.
(my mouse device is on ps2, but the codes only set /dev/input/mice device
originally)
Then I have done, I can use the mouse wheel when SDL uses frame buff driver.
I dont exactly know I did right or wrong, I just change it for my usuage.
Correct me please, if I did something wrong.

Using ctrl-alt-fn for flipping instead of alt-fn may help a few games that
actually use that key combination.
[Note: This is also consistent with X11 on the Linux console]
and SDL no longer builds on MacOS X 10.3 natively, as of the 7.0.4
QuickTime update.
MacOS X 10.4 is the new build baseline for the SDL MacOS X packages.
... it would shore be nice if I had it. :)
The configure script parses the value of $X_LIBS when looking at the
--enable-x11-shared, which is getting set on Ubuntu 5.10 to "-L/usr/X11R6/lib"
... however, Ubuntu stores all the Xlib stuff in /usr/lib.
The end result in SDL is that the dynamic X11 stuff gets disabled by default,
unless you override like this:
./configure --x-libraries=/usr/lib

Subject: [SDL] Window manager does not show SDL window titles
Hello,
I have an issue with SDL-using applications and the sawfish window manager.
The problem is that SDL windows do not show the window caption. My gnome
panel *does* show the window name, but the actual sawfish window frame
shows no caption at all. All other non-SDL applications that I use work
fine.
I tried a couple other window managers, and they *were* able to show the
SDL window captions correctly. Though there many be other WMs that can't.
I believe the problem is that SDL is using the UTF8_STRING type for the
window's WM_NAME and WM_ICON properties. In fact, WM_NAME and WM_ICON are
supposed to set to a TEXT type, usually STRING (ISO 8859-1).
The property names _NET_WM_NAME and _NET_WM_ICON_NAME should be used to
store the UTF8_STRING versions of the window title and icon name.
You can see the properties I refer to with a command like this:
xprop|grep -e "WM.*NAME"
Please note the freedesktop.org standard:
http://standards.freedesktop.org/wm-spec/wm-spec-1.3.html#id2506954
This page talks a little bit about the history of these properties. Just
search down the page for "WM_NAME".

Please let me know if I can be of any assistance in resolving this issue.
Thanks,

The palette -> RGBA blit wasn't following the rule:
* RGB->RGBA:
* SDL_SRCALPHA not set:
* copy RGB, set destination alpha to source per-surface alpha value.

Subject: [SDL] no software surfaces with svgalib driver?
Hi,
I noticed that the SDL (1.2.9) svgalib driver only makes use of linear
addressable (framebuffer) video modes. On older systems (like one of
mine), linear addressable modes are often not available.
Especially for cards with VESA VBE < 2.0 the svgalib vesa driver is
unusable, since VESA only supports framebuffering for VBE 2.0 and later.
The changes necessary to add support for software surfaces seem to be
relatively small. I only had to hack src/video/svga/SDL_svgavideo.c (see
attached patch). The code worked fine for me, but it is no more than a
proof of concept and should be reviewed (probably has a memory leak when
switching modes). It also uses the vgagl library (included in the
svgalib package) and needs to be linked against it.
