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).

Description of problem:
Enable wayland support for qxl-vga

Version-Release number of selected component (if applicable):
gdm-3.28.3-22.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Currently wayland support has been disabled in gdm for qxl-vga device on rhel 8.1:
# rpm -qf /usr/lib/udev/rules.d/61-gdm.rules 
gdm-3.28.3-22.el8.x86_64

# cat /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"

# disable Wayland on Matrox chipsets
ATTR{vendor}=="0x102b", ATTR{device}=="0x0522", RUN+="/usr/libexec/gdm-disable-wayland"
ATTR{vendor}=="0x102b", ATTR{device}=="0x0524", RUN+="/usr/libexec/gdm-disable-wayland"

# disable Wayland when using the proprietary nvidia driver
DRIVER=="nvidia", RUN+="/usr/libexec/gdm-disable-wayland"

# disable Wayland on hybrid graphics setups for now
SUBSYSTEM=="drm", KERNEL=="card[1-9]*", RUN+="/usr/libexec/gdm-disable-wayland"

 
Actual results:
wayland support for qxl-vga has been disabled in gdm

Expected results:
wayland support for qxl-vga is enabled

Additional info:
Comment 1 Gerd Hoffmann 2019-08-22 10:34:21 UTC 
Plan: enable early in the 8.2 cycle to give virt QE enough time for a full desktop test run with wayland enabled.
Comment 2 Ray Strode [halfline] 2019-08-23 14:37:13 UTC 
have the multihead issues been worked out?
Comment 3 Gerd Hoffmann 2019-08-26 07:21:34 UTC 
(In reply to Ray Strode [halfline] from comment #2)
> have the multihead issues been worked out?

Yes, it's sorted and should work fine with the 8.1 kernel.

Virt QE did most 8.1 testing with Xorg not wayland though,
thats why we want flip the switch early in 8.2 ...
Comment 4 Ray Strode [halfline] 2019-12-06 15:30:49 UTC 
i'm down for toggling this provided, QE thinks we still have enough runway.  I think we probably do?
Comment 8 Vitezslav Humpa 2020-01-14 09:09:55 UTC 
Verified with gdm-3.28.3-28.el8.x86_64, with wayland enabled both greeter and gnome session work as expected. Verified.
