There are two places where monitor descriptions are passed through the
RDP protocol:
- TS_UD_CS_MONITOR ([MS-RDPBCGR] 2.2.1.3.6 Client Monitor Data)
- DISPLAYCONTROL_PDU_TYPE_MONITOR_LAYOUT ([MS-RDPEDISP] 2.2.2.2)
The processing logic for both of them is similar enough that they should be unified.
Also update to define the constants for the maximum and minimum desktop width/height for monitors and total area.
Also a large number of clarifications for the constants and protocol
requirements.
Note that this is also the first step to making resizing work with the extension GFX channel as well as an important
foundational step to enable HiDPI compatibility.
Also some misc logging updates.
- Based on https://github.com/jsorg71/xrdp/tree/dynamic_monitor
- Tested with xorgxrdp
- Tested with vnc
- Only works with single monitor.
- Update documentation to clarify the difference between MSTSC and
Microsoft Remote Desktop.
- Does not include compatibility with /gfx at this time, which is still
in testing.
- Updates to include ms-rdpedisp.h header for the 2.2.2 specification of
the protocol.
- Adds new dynamic_monitor_layout struct that shares the number of
monitors with xrdp_client_info.h
- Does not allow for BPP changes because the RDP protocol doesn't
support it.
- Option to disable feature as NeutrinoRDP doesn't support it (It was
based on FreeRDP 1.0.1 which didn't yet have this feature.)
- Add CLIENT_MONITOR_DATA_MAXIMUM_MONITORS constant and reference
spec definition.
Depends on https://github.com/neutrinolabs/xorgxrdp/pull/183
