Description Oleg 2020-08-12 15:08:46 UTC
This problem has existed for many months already. While I am on the console (x11 or wayland are not loaded), 8 BSD logos sometimes appear in the left corner of my screen. The problem can be seen in the attachment provided. I use drm-devel-kmod/i915kms. I am running FreeBSD 13.0-CURRENT r364115, but as I said, this problem has existed for many months already.

This seems like it might be a bug in VT splash CPUs; as a workaround, the (non-default) splash cpus can be disabled by removing kern.vt.splash_cpu from loader.conf and sysctl.conf, or by setting a zero value.

While investigating PR 211922 I observed orb logos, despite kern.vt.splash_cpu=0.

I'm seeing this in FreeBSD 12.2-RC3 amd64 also. It is extremely reproducible: 1. In the framebuffer console run yes(1). 2. Left-click and drag the mouse. 3. Switch to another console. The orb logos (4, equalling the no. of CPUs) appear at the top-left corner and then the mouse pointer cannot be brought to the bottom of the screen anymore. It stops at what looks like (fb_height - orb_logo_height) of the screen.

This patch seemed to fix it for me: https://people.freebsd.org/~manu/0001-vt-Disable-splash_cpu-when-replacing-the-backend.patch
Comment 7 Oleg 2020-11-10 17:24:15 UTC
(In reply to Steve Wills from comment #6) It doesn't fix the issue for me.
Comment 8 Rajeev Pillai 2020-11-12 02:51:10 UTC
(In reply to Steve Wills from comment #6) That patch doesn't work for me either on FreeBSD 12.2-RELEASE with efifb.
