nanogui: Thread: X11 vs framebuffer

Can I configure my nanox application to execute on my touchscreen desktop
using X11 without the "Microwindows" app frame and mouse pointer displayed?
Or must I use a framebuffer device to accomplish this?
Thanks.

In src/config I have disabled the mouse drivers and set NOMOUSE=Y. I
don't
use nanowm and have only one window for the application (flnx) without
frame
and mouse pointer.

If you're going to run micorwindows on top of X11, and don't
want the X11 window dressings, then you'll either have to
position the X11 window off the screen to the top left, or
modify the X11 open call in drivers/scr_x11.c.  The microwindows
mouse pointer can be turned off in the config file.

Otherwise, its simpler using framebuffer!

The mouse pointer can be turned off in the config file (NOMOUSE = Y)
ONLY IF framebuffer support is selected (i.e. X11 = N), correct?

I assumed that X11 would have to be re-configured to turn off the mouse
pointer but that that would be an effect global to all Linux X11 apps.

I'll probably have to rebuild the kernel with framebuffer support and make
the mouse pointer disappear the correct way.

Thanks,

First, you're confusing the mouse driver with the cursor.  The
mouse driver can be turned off in the config file, which will
then automatically result in no cursor being displayed.  With
X11, the mouse and cursor are normally present.

Actually, that's incorrect.  See drivers/scr_x11.c::X11_open(),
an empty (invisible) X11 cursor is created with XDefineCursor.
X11 allows different cursors in every window.  Microwindows
always draws its own cursor, and instructs X11 never to.

No, that won't work.

To hide the cursor, add a GdHideCursor() as the last item in
nanox/srvmain.c::GsInitialize().  You might take a quick
look through this function to see how the cursor is initialized
in the first place.
