Package: gnumach Version: 2:1.3.99.dfsg.cvs20070211-1 Severity: The mouse pointer moves only in the vicinity of the left side and moves only vertically, when X starts on Hurd. When the package of gnumach is replaced with version: 2:1.3.99.dfsg.1-1+b1, the problem is solved. I suggest that this is a problem perhaps related to mouse's I/O. Thanks, -- Hiroyuki Yamamoto
