Even after applying the patch sent by dmitry, the problem seems to persist. = I've managed to track down the revision at which the problem appears, thoug= h. It shows up in 274085, when vt became the default console, though the pr= oblem shows up with both sc and vt. I may try reverting to before that point and applying your and dmitry's patc= hes and see if the problem shows up (however, for separate reasons, x11 is n= on-functional now for me) > On Nov 14, 2014, at 18:40, Adrian Chadd wrote: >=20 > Hi, >=20 > Thanks.
