** Description changed: * monitors.xml in Ubuntu 22.04, and 23.04 (GNOME) is starting with `<monitors version="2">`, while in Ubuntu MATE 22.04, and 23.04 it is starting with `<monitors version="1">` * The monitors.xml file name is defined here for MATE: https://github.com/mate-desktop/mate-desktop/blob/master/libmate-desktop/mate-rr-config.c#L44, and here for GNOME: https://gitlab.gnome.org/GNOME/mutter/-/issues/2919#note_1799008 #### Expected behaviour cinnamon is using a dedicated name, cinnamon-monitors.xml. This doesn't cause the file to be overwritten by the display preferences if other desktop environment are used on the same distro. If MATE and GNOME followed the same approach, the file name would be mate-monitors.xml, and gnome-monitors.xml, respectively. #### Actual behaviour - monitors.xml in Ubuntu 23.04: + monitors.xml in Ubuntu 23.04, and 22.04: ``` <monitors version="2"> <configuration> <logicalmonitor> <x>0</x> <y>0</y> <scale>1</scale> <primary>yes</primary> <monitor> <monitorspec> <connector>Virtual-1</connector> <vendor>unknown</vendor> <product>unknown</product> <serial>unknown</serial> </monitorspec> <mode> <width>1600</width> <height>900</height> <rate>60.000</rate> </mode> </monitor> </logicalmonitor> </configuration> - </monitors> - ``` - - monitors.xml in Ubuntu 22.04: - - ``` - <monitors version="2"> - <configuration> - <migrated/> - <logicalmonitor> - <x>0</x> - <y>0</y> - <primary>yes</primary> - <monitor> - <monitorspec> - <connector>Virtual-1</connector> - <vendor>???</vendor> - <product>0x0000</product> - <serial>0x00000000</serial> - </monitorspec> - <mode> - <width>1600</width> - <height>900</height> - <rate>60</rate> - </mode> - </monitor> - </logicalmonitor> - </configuration> - <configuration> - <logicalmonitor> - <x>0</x> - <y>0</y> - <scale>1</scale> - <primary>yes</primary> - <monitor> - <monitorspec> - <connector>Virtual-1</connector> - <vendor>unknown</vendor> - <product>unknown</product> - <serial>unknown</serial> - </monitorspec> - <mode> - <width>1600</width> - <height>900</height> - <rate>60</rate> - </mode> - </monitor> - </logicalmonitor> - </configuration> </monitors> ``` monitors.xml in Ubuntu MATE 22.04, and 23.04: ``` <monitors version="1"> <configuration> <clone>no</clone> <output name="Virtual-1"> <vendor>???</vendor> <product>0x0000</product> <serial>0x00000000</serial> <width>1600</width> <height>900</height> <rate>60</rate> <x>0</x> <y>0</y> <rotation>normal</rotation> <reflect_x>no</reflect_x> <reflect_y>no</reflect_y> <primary>yes</primary> </output> <output name="Virtual-2"> </output> <output name="Virtual-3"> </output> <output name="Virtual-4"> </output> </configuration> </monitors> ``` #### Steps to reproduce the behaviour Both GNOME and MATE can be installed on the same distro. Both DEs are installing "$HOME/.config/monitors.xml" via manually configured display GUI preferences: * GNOME via `$ gnome-control-center display` * MATE via `$ mate-display-properties` Steps I used to reproduce the issue in Ubuntu 22.04 (as a virtual machine): * Log into GNOME * Ubuntu comes with GNOME, so install MATE in addition: `sudo apt-get install mate-desktop-environment-extras mate-desktop-environment` * Run `$ gnome-control-center display`, change the "Resolution" to 1600x900, click on the "Apply": This will 1) generate "$HOME/.config/monitors.xml", 2) [Screenshot_ubuntu-22.04-desktop-amd64.iso-clone_2023-07-24_23_43_56](/uploads/dc4ba73ddfae955fcafa948e3a164581/Screenshot_ubuntu-22.04-desktop-amd64.iso-clone_2023-07-24_23_43_56.png). Close the window. * Log out from GNOME. From the display manager, log into MATE. * As you can see, the [screen resolution (1600x900 configured in GNOME) not used by MATE](https://github.com/mate-desktop/mate-control-center/assets/6416073/adffa08e-cf08-499d-8dc3-9e7800e4d7e9), instead a fallback resolution is used. * Run `$ mate-display-properties`, just click on the "Apply" button (you don't have to click on the "Keep this configuration" button that pop-ups in the dialoge-box), it will overwrite "$HOME/.config/monitors.xml" * Log out from MATE. From the display manager, log into GNOME. * As you can see, [Screenshot_ubuntu-22.04-desktop-amd64.iso-clone_2023-07-24_23_40_11](/uploads/013b2b1abf582caf7e6c4c70733ea5ac/Screenshot_ubuntu-22.04-desktop-amd64.iso-clone_2023-07-24_23_40_11.png), instead a fallback resolution is used. ## Links to bug reports [Feature request] mate-display-properties: Please upgrade monitors.xml from <monitors version="1"> to <monitors version="2"> - https://bugs.launchpad.net/ubuntu/+bug/2028818 GNOME https://gitlab.gnome.org/GNOME/mutter/-/issues/2919 MATE https://github.com/mate-desktop/mate-control-center/issues/712 ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: gnome-control-center 1:41.7-0ubuntu0.22.04.6 ProcVersionSignature: Ubuntu 5.19.0-43.44~22.04.1-generic 5.19.17 Uname: Linux 5.19.0-43-generic x86_64 ApportVersion: 2.20.11-0ubuntu82.5 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Mon Jul 24 01:24:22 2023 InstallationDate: Installed on 2023-04-17 (97 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) SourcePackage: gnome-control-center UpgradeStatus: No upgrade log present (probably fresh install)
