Works around a silly bug in the kernel that causes wakeup storms after
too many keypresses. Should fix the kernel bug too, but this at least
keeps the idle wakeup count below 1000/sec.
Usually, the console is set to RAW in the kbd driver. If we hotplug all input
devices (i.e. the evdev driver for keyboards) and the console is left as-is.
As a result, the evdev driver must put an EVIOCGRAB on the device to avoid
characters leaking onto the console. This again breaks many things, amongst
them lirc, in-kernel mouse button emulation and HAL.
This patch sets the console to RAW if AllowEmptyInput is on.
Use-cases:
1. AEI is off
1.1. Only kbd driver is used - behaviour as-is.
1.2. kbd and evdev driver is used: if evdev does not grab the device,
duplicate events are generated.
2. AEI is on
2.1. Only evdev driver is used - behaviour as-is, but evdev does not need
to grab the device anymore.
2.2. evdev and kbd are used: duplicate key events are generated if evdev
does not grab the device.
1.2 is a marginal use-case that can be fixed by adding a "grab" option to the
evdev driver (update of xorg.conf is needed).
2.2 is an issue. If we have no ServerLayout section, AEI is on, but devices
specified in the xorg.conf are still added [1], resulting in duplicate events.
This is a common configuration and needs sorting out.

Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
change "foo.h" to <X11/foo.h> for core headers, e.g. X.h, Xpoll.h;
change "foo.h", "extensions/foo.h" and "X11/foo.h" to
<X11/extensions/foo.h> for extension headers, e.g. Xv.h;
change "foo.[ch]" to <X11/Xtrans/foo.[ch]> for Xtrans files.
permissions when no access to HW registers is required. For API changes
which mostly involve the modifications to make the RRFunc (introduced
with 6.8) more flexible please check Bugzilla #2407. NOTE: This patch
applies changes to OS specific files for other OSes which I cannot
test.
relied on the generic VGA layer to restore text console fonts for us
when shutting down the server or VT switching back to the text console.
This has worked rather well but it has some downsides on Linux: a. Many
people use fbdev as console text mode. In this case it is not necessary
to save/restore console fonts as the console is running in graphics
mode anyway. b. Some architectures don't have a fbdev console but
require a full POST of even the primary card (ie. IA64). This posting
has to take place before we even have a chance to save anything.
Therefore the fonts we save are the once written to the chip by POST,
not what has been programmed by the user. c. Certain chipsets utilize
the BIOS to perform mode setting. This may interfer with the vga
save/restore font function in a strange way. It would therefore be
preferrable to let the OS - which has been used to set up the font in
the first place - take care of saving/restoring the data. I will attach
a patch which will do so for Linux. To make this fully functional a
small patch needs to be applied to the Linux kernel. To disable this
feature add: #define DoOSFontRestore NO to your host.def. (Bugzilla
#2277)
