** Description changed: * "$HOME/.config/monitors.xml" is not installed by default in Ubuntu during the installation at this writing, you have to generate it by running the GUI preferences `$ gnome-control-center display` for GNOME, and `$ mate-display-properties` for MATE. * Both GNOME and MATE can be run on the same distro, which causes compatibility issues with monitors.xml: 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 for MATE is defined at https://github.com/mate-desktop/mate-desktop/blob/master/libmate-desktop/mate-rr-config.c#L44, and for GNOME it is defined at 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, and 22.04: + monitors.xml in Ubuntu 23.10, 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> + <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 (with ubuntu-mate-desktop installed), or 23.04 (with ubuntu-mate-desktop installed): ``` <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>60.000</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>1280</width> - <height>800</height> - <rate>59.810</rate> - </mode> - </monitor> - </logicalmonitor> - </configuration> + <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>60.000</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>1280</width> + <height>800</height> + <rate>59.810</rate> + </mode> + </monitor> + </logicalmonitor> + </configuration> </monitors> ``` monitors.xml in Ubuntu MATE 22.04, Ubuntu MATE 23.04, ubuntu-mate-desktop from Ubuntu 22.04, or ubuntu-mate-desktop from Ubuntu 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> + <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 Steps I used to reproduce the issue in Ubuntu 22.04 with ubuntu-mate-desktop installed: * Log into GNOME * Ubuntu comes with GNOME, so install MATE in addition: `sudo apt-get install mate-desktop-environment-extras mate-desktop-environment` * Log out, and log in to MATE. * 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 generate "$HOME/.config/monitors.xml" * Log out from MATE. From the display manager, log into GNOME. * As you can see, the screen resolution (1600x900 configured in MATE) not used by GNOME (https://github.com/mate-desktop/mate-control-center/assets/6416073/1b978bd7-22dd-4b42-a5b5-d32ec2d42f21), instead a fallback resolution is used. * Run `$ gnome-control-center display`, change the "Resolution" to 1600x900, click on the "Apply": This will 1) move "$HOME/.config/monitors.xml" (that was generated by MATE) to "$HOME/.config/monitors-v1-backup.xml" 2) generate a new "$HOME/.config/monitors.xml" 3) Change the screen resolution directly (https://github.com/mate-desktop/mate-control-center/assets/6416073/6a841086-6936-4a21-9d43-ca1a605a9806).
