[Bug 2020782] Re: Xdcv: Changing display scale setting and reverting it fails
I've also tested the "vv5" package in a fresh VM and can confirm that zero hz is now supported, and now facing the same scenario where multiple monitors are automatically enabled. Another issue that still stands is the "config history" issue I've mentioned. If you exclusively change the resolution from gnome display settings, it can apply a new resolution and revert to a previous config (via the timeout prompt) without any issue. But when the resolution is changed via the NICE DCV client's options (or via `xrandr` for that matter), mutter does not register that resolution change in `config_history`, and cannot revert back to the previous config when prompted. This is reproducible with just the default gnome desktop environment and the `xrandr` The reproducer is as follows: (assume that the initial resolution is 1920x1080) - Set a resolution via `xrandr`, e.g. (1366x768) - Open gnome display settings, and try to set the resolution to 1024x768 - Press "revert back" when prompted - The resolution will not go back to 1366x768 as it should and will stay at 1024x768 I've debugged this and noticed that gnome display settings use mutter's org.gnome.Mutter.DisplayConfig DBus interface and calls ApplyMonitorsConfig for resolution changes, whereas neither NICE DCV nor xrandr does that, so mutter is not notified about the change. I guess this will need a separate issue. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2020782 Title: Xdcv: Changing display scale setting and reverting it fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2020782/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 2020782] Re: Xdcv: Changing display scale setting and reverting it fails
Hello Daniel, I've also been debugging this issue and noticed something weird while reproducing it. It seems that resizing the screen via resizing the NICE DCV client does not invoke the `meta_monitor_config_manager_set_current` method, so the current config and the history are untouched. Let's say we have an initial resolution of QxZ@T hz, sf 1(scale factor). The NICE DCV client screen resize changes it to WxH@F sf 1.5, but libmutter still thinks the screen is at QxZ@T sf 1. At this point, `xrandr` output no longer shows QxZ@T hz as a supported resolution. When the user tries to change the scale, the change is registered as both the resolution change and the scale change as per the perspective of "libmutter", and if the user proceeds to accept this configuration, everything is fine because the Xdcv already lists `WxH@F` as a supported resolution, but if not (i.e. user tries to revert back to the previous) it fails because QxZ@T hz is no longer on the supported resolution set. Therefore, I think one of the problems we're facing here is libmutter/Xdcv being out-of-sync when the screen resolution is changed via the NICE DCV client. I'm currently looking into how we can reflect the client resolutions to libmutter (I'm not well-versed in mutter codebase so progressing a little bit slow) I'll continue to post my findings as I progress. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2020782 Title: Xdcv: Changing display scale setting and reverting it fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2020782/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
