The question is what, or rather who is going to actually __do__ something about it? The choices are you (wf), grehkh, the TTY IO subsystem maintainer (now we can give them an agreed mingetty source) ie post to LKML, me (omb)? I am quite busy and dont know the TTY subsystem well. Does gregkh have a recommendation/preference for this??? I think getting this fixed in (Open)SuSE is quite important as it really kills you when something goes wrong in the X sub-system and do <ctl><alt>Fn to get a non X login to investigate what got screwed up. Not finding a getty is a real newbie killer, since, unless they think of SysReq or ssh it is likely to be the power switch, and no wiser what _really_ went wrong. I really do not like it when Linux regressions give the M$ windows effect. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
