* How many cards do we have? autodetection?

|
* Is our card a dualhead card?
|

|
|
* How many monitors are connected?
|

|

|
|
* difference between one and two card is different device sections
|

- Warning: Xinerama vs. DRI
|
||
|
|
* "unlinking" the sliders will yield a warning "Using different
|
||
|
|
resolutions on the screens will disable 3D hardware acceleration on
|
||
|
|
the second head", which is a Xinerama deficiency).
|
||
|
|
|
||
|
|
Note: Probably only Ati and nvidia do support mergedFB properly, other
|
||
|
|
drivers might lose xinerama features like placement and maximize

|
|
- Drag and drop widget
|
||
|
|
* The fun part: implementing a Drag and Drop widget where the (resizing)
|
||
|
|
screens can be dragged into their respective relative position,
|
||
|
|
"snapping" in the more obvious ones, i.e. plain "left of" and "right
|
||
|
|
of", "above" and "under" (without offset).

- displayconfig.MonitorPreview:
|
||
|
|
Singleheadpreview: Monitor keeps size
|
||
|
|
DualheadPreview: like now, monitor resizes to show relative screen size

Displayconfig; Notes abstractielaag
|

|
-------------------------------------
|
||
|
|
* een XSetup heeft N gfxcards.
|
||
|
|
* een GfxCard heeft N Monitors
|
||
|
|
* XSetup is een container voor alle objecten uit de abstractielaag.
|
||
|
|
* XSetup.addMonitor(monitor,gfxcard) waarbij gfxcard al in XSetup zit en een
|
||
|
|
referentie naar de kaart vormt waarop monitor is aangesloten.
|
||
|
|
* Een Adaptor heeft een 1:1 relatie met een monitor, en is 'onderdeel' van
|
||
|
|
een "Screen" (in de zin van Screen section uit xorg.conf)
|
||
|
|
* Controls zoals resize en de rotatie / mirroring widgets manipuleren een
|
||
|
|
Adaptor, die intern de Screen manipuleert
|
||
|
|
* Singlehead resolutie verandert via xrandr en slaat settings op via
|
||
|
|
displayconfig-restore.py
|
||
|
|
* Dualhead resolutie aanpassen pakt intern een passende metamode (bij twinview)
|
||
|
|
en checkt of alle zinvolle metamodes beschikbaar zijn, anders wordt de user
|
||
|
|
gewaarschuwd dat dit eerst moet gebeuren.
|
||
|
|
* Adaptor in dualhead / twinview modus worden dus naar een screen vertaald
|
||
|
|
metamodes heeft.
|
||
|
|
* Screen moet dan nog support voor metamodes krijgen.

displayconfig:

|
|
===============
|
||
|
|
* Current resolution doesn't get recognized if current != highest resolution
|
||
|
|
* new tab display powermanagement, just like the existing tab, we need to be
|
||
|
|
able to at least replace existing functionality

New Widgets:
|
||
|
|
-------------
|
||
|
|
* DualheadPreview
|
||
|
|
* RadioButtons instead of dropdown for Positioning
|
||
|
|
|
||
|
|
* Detect if we're already running on dualhead, (en|dis)able widgets accordingly
|
||
|
|
* Nvidia MergedFB
|
||
|
|
- Make preview of dualhead more clear (only xinerama or also mergedFB?)
|
||
|
|
- Generate list of Metamodes from resolutions available
|
||
|
|
- write dualhead settings to xorg.conf
|
||
|
|
* Compare dualhead with different drivers WRT xorg.conf
|
||
|
|
- generic Xinerama (Matrox, others?)
|
||
|
|
- dualhead for fglrx, SiS ...
|
||
|
|
- MergedFB as special case for nvidia (sis?)
|
||
|
|
* Preview should be rotatable (and|or) resizable (and|or) DualHeadpreview?
|
||
|
|
* Add missing elements to DualHeadTab
|
||
|
|
- [ ] Use MergedFB (binds two resolution sliders)
|
||
|
|
- label with warning "You can only use DRI on one head with different resolutions blahblah"
|
||
|
|
FIXME: enabling Dualhead should:
|
||
|
|
- Update resolutions with "metamodes"
|
||
|
|
- disable Rotation/mirroring stuff
|
||
|
|
- Add ServerLayout to xorg.conf
|
||
|
|
- Add second Screen to xorg.conf
|
||
|
|
- Alternatively (if both resolutions are the same enable MergedFB
