            Bug ID: 479002
           Summary: Wayland atomic mode-setting cursors not shown on
                    vmwgfx driver
    Classification: Plasma
           Product: kwin
           Version: git master
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: platform-drm
          Assignee: kwin-bugs-n...@kde.org
          Reporter: stefan.hoffmeis...@econos.de
  Target Milestone: ---

SUMMARY

When forcing on atomic mode-setting through `export KWIN_DRM_NO_AMS=0` on KDE
Plasma 6 git master (beta2+) in a Wayland session, on VMware Workstation
(vmwgfx kernel driver), no cursor is shown.

Looking at

`watch -n 1 "drm_info | grep -E 'Plane|Connector|FB_ID|\"CRTC'"`

suggests that the plane is assigned to the right CRTC, that the FB_ID changes.
There is no applicable log output at level debug+.

STEPS TO REPRODUCE
1. force atomic mode-setting to on via `export KWIN_DRM_NO_AMS=0`
2. make sure that software cursors are _not_ on (i.e. _not_
KWIN_FORCE_SW_CURSOR=1)
3. log into Plasma Wayland session

OBSERVED RESULT

No cursor visible on screen, but system _acts_ as if there is a cursor present
(clicks etc work)

EXPECTED RESULT

Cursor visible on screen.

ADDITIONAL INFORMATION

Note that right now forcing on of KWIN_DRM_NO_AMS is required due to the Linux
kernel (virtual graphics drivers) lacking some capabilities in version
6.7.0-rc5. With Linux kernel 6.8 these capabilities will be present in the
kernel and kwin will automatically enable atomic mode-setting.
