xf86-video-nestedv: driver to run Xorg on top of Xorg or something else
= Usage =
This is how I test it:
X -config my.conf -noreset -retro :1
(if your Xorg server is old you might need "-sharevts vt7", in case your
bottom-layer X runs on vt7)
My xorg.conf:
-- begin xorg.conf --
Section "ServerFlags"
Option "AutoEnableDevices" "false"
Option "AutoAddDevices" "false"
EndSection
Section "Device"
Identifier "device1"
Driver "nestedv"
Option "Display" ":0" # you can omit this
EndSection
Section "Screen"
Identifier "screen1"
Device "device1"
DefaultDepth 24
Option "Origin" "100 100" # you can omit this
SubSection "Display"
Depth 24
Modes "640x480"
EndSubSection
EndSection
Section "ServerLayout"
Identifier "layout1"
Screen "screen1"
EndSection
-- end xorg.conf --
If you want to have an input device you need 3 things:
- add another input device to your machine
- configure your bottom-layer xorg.conf to _not_ use that device (you'll
probably have to disable input hotplug and add InputDevice sections in
xorg.conf)
- configure your top-layer xorg.conf to use that device
In the future I'll write xf86-input-nestedi so you'll be able to use it =)
You can also have more than one screen with this driver. Here's an example of a
xorg.conf with 2 screens and a mouse:
-- begin xorg.conf --
Section "ServerFlags"
Option "AutoEnableDevices" "false"
Option "AutoAddDevices" "false"
EndSection
Section "Device"
Identifier "device1"
Driver "nestedv"
EndSection
Section "Device"
Identifier "device2"
Driver "nestedv"
EndSection
Section "InputDevice"
Identifier "mouse1"
Driver "evdev"
Option "device" "/dev/input/event7"
EndSection
Section "Screen"
Identifier "screen1"
Device "device1"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "640x480"
EndSubSection
EndSection
Section "Screen"
Identifier "screen2"
Device "device1"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "640x480"
EndSubSection
EndSection
Section "ServerLayout"
Identifier "layout1"
Screen "screen1"
Screen "screen2" RightOf "screen1"
InputDevice "mouse1"
EndSection
-- end xorg.conf --

TODO
- check if minimum/maximum virtual sizes are set correctly
- I guess most/all code that deals with mode is somehow wrong
- define a real policy for the modes we allow the user to use
- require 1.8 ABI because of HW_SKIP_CONSOLE?
- add some checking for when the bottom-layer X dies?
- standardize function definitions (coding style)
- implement FreeScreen? (http://www.x.org/archive/X11R6.8.2/doc/DESIGN6.html#38)
- implement the code that validates depths, implement other checks
- compare Xlib's bpp with pScrn's bpp? is it needed? other similar checks?
- add some Option "fullscreen"? (for Multiseat)
- write the xcb backend
- write other backends (for different window systems, or maybe using portable
libraries like SDL or Qt)
- ability to detach from one xserver and attach to other?
- be fully xrandr-aware
- xv?
- other extensions?
- improve the code that redraws the screen (damage tracking)
- fully understand the fb/shadow code to get a clue on what's really going on =)
- write a man page
