Description of problem: If we install RHEL7.6 or RHEL7.7 on a VM which have Cirrus Logic graphics, 00:02.0 VGA compatible controller [0300]: Cirrus Logic GD 5446 [1013:00b8] (prog-if 00 [VGA controller]) System Information Manufacturer: Red Hat Product Name: KVM Version: RHEL 7.0.0 PC We are getting following errors in the /var/log/messages logs: $ less /var/log/messages|grep wayland Jul 29 23:32:35 HOSTNAME systemd-udevd: failed to execute '/usr/libexec/gdm-disable-wayland' '/usr/libexec/gdm-disable-wayland': No such file or directory Jul 29 23:42:00 HOSTNAME systemd-udevd: failed to execute '/usr/libexec/gdm-disable-wayland' '/usr/libexec/gdm-disable-wayland': No such file or directory Jul 30 21:27:24 HOSTNAME systemd-udevd: failed to execute '/usr/libexec/gdm-disable-wayland' '/usr/libexec/gdm-disable-wayland': No such file or directory There is no visible impact of the error message. Version-Release number of selected component (if applicable): gdm-3.28.2-16.el7.x86_64(RHEL7.7) gdm-3.28.2-12.el7_6.2.x86_64(RHEL7.6) How reproducible: Always Steps to Reproduce: 1. Install RHEL7.6 or 7.7 on a VM. Make sure to use Cirrus Logic graphics on the system. 2. Start the system in GUI mode, Switch runlevel from textmode to Gui mode. Actual results: "/usr/libexec/gdm-disable-wayland" missing and getting above mentioned message in the logs. Expected results: Add the missing file so that there is no error message. Additional info: The error appears in the log due to the following udev rule: RHEL7.7 ~]# vim /usr/lib/udev/rules.d/61-gdm.rules # disable Wayland on Cirrus chipsets ATTR{vendor}=="0x1013", ATTR{device}=="0x00b8", ATTR{subsystem_vendor}=="0x1af4", ATTR{subsystem_device}=="0x1100", RUN+="/usr/libexec/gdm-disable-wayland" The above mentioned udev rule is added by gdm: RHEL7.7 ~]# rpm -qf /usr/lib/udev/rules.d/61-gdm.rules gdm-3.28.2-16.el7.x86_64 But the GDM package available in RHEL 7.6 or RHEL 7.7 does not provide "/usr/libexec/gdm-disable-wayland". The "/usr/libexec/gdm-disable-wayland" file is provided by the gdm package in Fedora, but not in RHEL. Fedora30 ~]$ rpm -qf /usr/libexec/gdm-disable-wayland gdm-3.32.0-3.fc30.x86_64
