Description Warren Block freebsd_committer freebsd_triage 2014-08-13 12:35:23 UTC 
Tested on 10.0-STABLE amd64 r269851.

With hw.vga.textmode=1, Scroll Lock to enable scrollback does not work on ttyv0.  The screen locks but does not scroll.  Scrollback works on other virtual
terminals, just not on ttyv0.

moused does not work when hw.vga.textmode=1.  Even though moused is running, the mouse pointer does not appear, and marking or pasting text does not work.  This happens on all virtual terminals.  (Tested with USB mouse, so this is the "nondefault" version of moused, and does not need to be enabled in rc.conf by default.)

Setting hw.vga.textmode=0 makes scrollback work on all ttys, and moused functions again.

The problem with scrollback on ttyv0 when using textmode is fixed in HEAD as of r271250. I still need to MFC it.

Regarding moused and textmode, it's not implemented, even in HEAD.

I think this issue should be included in the Open Issues section in the 10.1-RELEASE Errata.

To submitter: was this issue ever fixed in later versions of FreeBSD?

Works in 13.2-stable, I don't have older systems to test.

Let's close as overcome by events then.
