[PATCH 0/9] MR5057: Draft: winewayland.drv: Use virtual display devices to implement mode change emulation
This WIP branch prototypes the usage of virtual display devices (through "virtual desktop" mode at the moment) to support display mode emulation in the Wayland driver. It works by allowing the driver to mark each host adapter with a virtual_id, which, if present, signals to win32u that it should include the adapter in the virtual display configuration. The virtual configuration (along with the virtual ids) is reported back to the driver though a new user driver function. If none of the host adapters is marked with a virtual id (i.e., all other drivers) we fall back to the single virtual display mode as before. Some deficiencies and open questions with the prototype: 1. Virtual desktop mode implies a lot of behavior that we don't want at this point the Wayland driver (e.g., taskbar window, changing the display mode to the virtual desktop resolution at startup, some changes in fsclip behavior). One way forward would be to have a "virtual display devices" mode separate from the "virtual desktop" mode, so that drivers can opt in only to the desired behavior (virtual desktop would imply virtual devices, to maintain the current behavior). 2. It's not clear to me what would be the best way for a driver to opt in or out of certain core behavior. Perhaps the driver would change some volatile registry key which other components would consult? Or introduce a user driver function for core to query the driver about such features on demand? Is there some precedence I can get inspiration from? 3. At the moment, the prototype calls the new "NotifyVirtualDevices" user driver callback only in the process which the display update occurred. This means that other processes don't get notified of the virtual devices mapping to host devices, so, in the Wayland driver case, we are not able to scale windows from those processes properly. One approach would be for core to ensure that the NotifyVirtualDevices callback is called once in all processes, but I am not sure what's the best way to achieve this (or even if this is the preferred approach). Another way would be to have a mechanism for the driver to query the virtual device info (+mappings) on demand, and just broadcast a message to all windows. In this case it could even be done internally by the driver (so more in line with what the part-12 MR is doing), if we don't want to introduce a more global behavior. Perhaps there is some even better mechanism, which would also be more fitting to how we envision the virtual display/devic es to evolve going forward. Let me know what you think! -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057

Hey, thanks for your beautiful work arround the wayland driver! I have been following the development since a while and patiently waiting, but one big issue i have still isn't fixed. When playing ManiaPlanet or TrackMania United Forever (i didn't test with others but these 2 have the problem for me which basically makes the wayland driver unusable for me), the screen resolution gets picked up from my second 1080p monitor, and not my 1440p main monitor. This way i can't play at the full resolution no matter what i do:   is there any way to fix this or is that a shortcoming of the wayland driver? It works fine on winex11.

I have pushed my own proposed changes/fixes on top of your branch at https://gitlab.winehq.org/afrantzis/wine/-/commits/virtual-desktop. With those changes the branch works well for me.
Here are some notes: 1. The virtual-desktop branch successfully virtualizes the adapter modes, but leaves the monitor rectangles as they are, which causes issues with a lot of calculation and checks (e.g., a fullscreen window will not be detected by `NtUserIsWindowRectFullScreen`). The part-12 MR was able to provide consistent monitor information/placement since the virtualization was done by the driver itself. The current WIP MR works around the issue by ignoring the host monitors and arbitrarily creates a virtual monitor with the proper rectangles for each virtual adapter. In my proposed virtual-desktop changes I have tried to solve this by automatically scaling the monitor rectangles. 2. Concerning integrating the scale factor with the DPI, the proposed approach does make sense to me, insofar as it reflects the actual (relative) DPI. However, I am skeptical because we will end up returning DPI values less than 96, and I am concerned that this may cause issues in applications in which 96 is assumed to be a minimum. As you note, the alternative would be to allow each driver to somehow get or calculate the mode scale factor and apply it internally as it sees fit (so I guess something closer to part-12 MR in this respect, at least in how the driver handles the scaling, if not in the actual mechanism to communicate the info). 3. The virtual-desktop branch uses the adapter_key to get the current settings from the registry during updates, which depends on the driver advertising adapters with the same order across processes. The Wayland protocol doesn't guarantee such ordering, but the Wayland driver mostly alleviates this since it sorts the adapters internally before sending them to win32u. 4. In the future we will need a way to associate a wl_output (by name, which is guaranteed to be cross-process consistent) to each adapter (e.g., so that if an app requests to become fullscreen on a particula monitor/adapter, we know that this corresponds to a particular wl_output and request it from the compositor). My proposed MRs implement such an association (each in a different way), but the virtual-desktop branch doesn't at the moment. We don't need to resolve this now if it's not directly needed by the approach we choose for the display mode changes, but I am mentioning it so that it's taken into account for any design evolution. --- One concern (related to (3) and (4), although I think non-critical, so we can leave it for later), that hasn't been resolved in any of the MRs so far, is what happens when processes transiently disagree about the adapters when a user adds/removes an monitor (and the corresponding wl_output addition/removal has been handled in one process but not another). For the Wayland driver the desktop process is the authoritative source of display info (i.e., the one handles UpdateDisplayDevices), but ChangeDisplaySettings does force an UpdateDisplayDevices invocation in other processes. In a worst case scenario: 1. Desktop process handles wl_output event and updates display devices. 2. Another process, which hasn't handled the wl_output event yet, calls ChangeDisplaySettings which may update the devices with stale information. Ideally, to avoid problems, I wouldn't want to update the display devices during a change display settings sequence, just let the process act on the existing registry information. Perhaps we can have an UpdateDisplayDevices parameter to signal when the update is part of a settings change, or I can track that manually in the driver (record it with trivial ChangeDisplaySettings handler). Another thought would be for the driver to only act on UpdateDisplayDevices in the desktop process (but I remember we tried something similar in the early Wayland driver MRs and that was causing issues). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057#note_60980

Regarding 1), I was expecting monitor rects to be correct (as in matching the virtual mode), but maybe I missed something. There's some DPI conversion in the NtUserGetMonitorInfo which I'm not completely sure it is doing. There's also some issues with `get_win_monitor_dpi` / `get_dpi_for_window` which will need to be sorted out. I tried to break up some recursive dependency in one of the commit but I later saw that it's was not enough and triggered some user lock asserts. Regarding 2), what about increasing the system_dpi when virtual modes are used so that the smallest mode ends up with 96dpi? Not entirely sure how to do that, and it will probably also require changing the wayland driver scaling computation. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057#note_60984
Regarding 2), what about increasing the system_dpi when virtual modes are used so that the smallest mode ends up with 96dpi? Not entirely sure how to do that, and it will probably also require changing the wayland driver scaling computation.
Or maybe instead of changing system_dpi which *will* be seen by every application, decide that Wine virtualized monitor dpi will always be relative to 96dpi at 640x480, the minimum supported resolution, and let driver adjust their scaling. Only per-monitor DPI aware applications should be able to read that, and we can only hope that they'll be happy about it. Still remains the question to whether changing DPI dynamically is a good idea, I can very well imagine per-monitor DPI aware app deciding to adjust things based on that after they changed display modes. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057#note_61007
I was expecting monitor rects to be correct (as in matching the virtual mode), but maybe I missed something. There's some DPI conversion in the NtUserGetMonitorInfo which I'm not completely sure it is doing.
Here is an attempt to summarize my current understanding: * physical dpi: The "real" dpi of the adapter, currently assumed to match `system_dpi` since we don't have per-adapter dpi reporting. * virtual dpi: The dpi of the adapter after a virtual mode change (matches physical dpi if there is no virtual mode change) * adapter dpi: Previously reported physical dpi (= `system_dpi` ), now virtual dpi. * monitor dpi: At the moment returns the respective adapter dpi (so now also returning virtual dpi) The drivers (through `UpdateDisplayDevices`) report monitor rect information in physical dpi. Your proposal has uncovered a few pre-existing inconsistencies in how monitor rects are treated. Some functions assume that the monitor rects are expressed in `system_dpi` (the get\_\*\_rect helper functions in sysparams.c) whereas others assume they are expressed in their respective adapter dpi. That was OK before because all those dpi values were the same. The change proposed in my virtual-desktop branch transform the monitor rects to account for the virtual mode change. This involves mapping from physical dpi to virtual dpi, but the transformation is done relative to the adapter origin coordinates. This means that the functions that assumed the rects are in adapter dpi now work, but the functions that make different assumptions now need fixing.
Regarding (2)... Or maybe instead of changing system_dpi which _will_ be seen by every application, decide that Wine virtualized monitor dpi will always be relative to 96dpi at 640x480, the minimum supported resolution, and let driver adjust their scaling
Right, so we can play with the monitor dpi value reported to applications (i.e., dissociate from the real "virtual dpi") in various ways. I am not sure I understand how the 96dpi at 640x480 approach would work, though, can you explain that a bit more? I was thinking that one way would be for the `get_monitor_dpi` sysparam.c function to return `max(96, real_monitor_dpi)` (so that's the value all public APIs will get), but then allow the driver to somehow know (or figure out) the `real_monitor_dpi` value and apply the residual scaling as required. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057#note_61463

I meant that every monitor would always report 96dpi when their virtual mode is 640x480, and then adjusted virtual dpi for higher virtual modes. This way we would never report a monitor dpi < 96, and break applications that don't expect it to be possible. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057#note_61464
Still remains the question to whether changing DPI dynamically is a good idea, I can very well imagine per-monitor DPI aware app deciding to adjust things based on that after they changed display modes.
This is a pertinent question, since, from what I understand, display mode changes under Windows don't lead to any changes in the reported DPI. I don't know if/how applications may be confused by that. In the model from my previous post, we just return the physical dpi (currently =`system_dpi`) as the monitor dpi and the driver will then apply all the needed scaling (so effectively what part-12 and this draft are doing). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057#note_61467

I've done some tests and it doesn't seem to work like it does with x11. this is the SWAT 4 game through... xwayland without this MR:  xwayland with this MR:  wayland without this MR:  wayland with this MR:  In native x11, this MR works perfectly. However, in wayland there is no effect (as shown in the screenshots), so I wonder if this is due to a lack of support from the wayland driver or is a bug. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057#note_96854

The lack of centering and obscuring of the background is a compositor issue. Which compositor are you using (kwin?)? When you change resolution from "settings" does the game resolution change accordingly?

When you change resolution from "settings" does the game resolution change accordingly? I'm using labwc/wlroots. No. The maximum resolution that appears in the settings menu is 1600x1200 and when I select it, the game is not filled to the resolution of my monitor. However, if I press the shortcut that toggles the window's fullscreen and then press the shortcut that toggles the window's maximization state, the game is filled to my monitor's resolution.
This behavior happens with all 4 games I tested: Ghost Recon 1, Splinter Cell 1 and 2 and SWAT 4. In Splinter Cell 1, I can set the resolution to 1920x1080 and in-game the game is filled to my monitor's resolution, but the menus, loadings and cut-scenes are not. In Splinter Cell 2 it's worse, I can't set the resolution to 1920x1080 (because the game itself doesn't support it) and even when I change to the maximum resolution that the game supports, somehow the game resets to a lower resolution (this in-game, in the menus, loadings and in the cut-scenes). In x11, in all cases, all 4 games are filled to the resolution of my monitor. By the way, I tested this MR here (`winewayland.drv: Use virtual display devices to implement mode change emulation`) and it works perfectly like x11! -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057#note_96914

I opened it at https://bugs.winehq.org/show_bug.cgi?id=57925. I didn't understand exactly which bug I should open it for, so I opened it for lack of support for display mode change, but in the logs I reproduced it as you asked (trying to change the resolution of SWAT 4).
