Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
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
