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.

Doc Type: Known Issue
Doc Text:
.Limitations of the *Wayland* session With Red Hat Enterprise Linux 8, the GNOME environment and the GNOME Display Manager (GDM) use *Wayland* as the default session type instead of the *X11* session, which was used with the previous major version of RHEL. The following features are currently unavailable or do not work as expected under *Wayland*: * *X11* configuration utilities, such as `xrandr`, do not work under *Wayland* due to its different approach to handling, resolutions, rotations, and layout. You can configure the display features using GNOME settings. * Screen recording and remote desktop require applications to support the portal API on *Wayland*. Certain legacy applications do not support the portal API. * Pointer accessibility is not available on *Wayland*. * No clipboard manager is available. * GNOME Shell on *Wayland* ignores keyboard grabs issued by most legacy *X11* applications. You can enable an *X11* application to issue keyboard grabs using the `/org/gnome/mutter/wayland/xwayland-grab-access-rules` GSettings key. By default, GNOME Shell on *Wayland* enables the following applications to issue keyboard grabs: ** *GNOME Boxes* ** *Vinagre* ** *Xephyr* ** `virt-manager`, `virt-viewer`, and `remote-viewer` ** `vncviewer` * *Wayland* inside guest virtual machines (VMs) has stability and performance problems. RHEL automatically falls back to the *X11* session when running in a VM. If you upgrade to RHEL 8 from a RHEL 7 system where you used the *X11* GNOME session, your system continues to use *X11*. The system also automatically falls back to *X11* when the following graphics drivers are in use: * The proprietary NVIDIA driver * The `cirrus` driver * The `mga` driver * The `aspeed` driver You can disable the use of *Wayland* manually: * To disable *Wayland* in GDM, set the `WaylandEnable=false` option in the `/etc/gdm/custom.conf` file. * To disable *Wayland* in the GNOME session, select the legacy *X11* option by using the cogwheel menu on the login screen after entering your login name. For more details on *Wayland*, see link:https://wayland.freedesktop.org/[].

Description Mike Cao 2020-02-03 04:02:32 UTC
Hello Documentation team 

From RHEL8.0 release note https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/8.0_release_notes/rhel-8_0_0_release#desktop 
(chapter 5.1.8)
It it clearly mentioned that Multi-GPU setups are not supported under Wayland.


but in RHEL8.1 and RHEL8.2 beta release note. I found this has been removed. so may we know why this has been removed. and whether we support Multi-CPU setup feature in RHEL8.1 or 8.2 beta?

Hope to hear you soon

Best Regards,
Mike

I've copied the limitations as listed in the RHEL 8.0 release notes into the Doc Text field here. I'll discuss with the desktop and graphics team if all of the limitations still apply. Then, I'll publish the edited release note.
