Had a go with the shiny new X (thanks!) on the sandy bridge laptop
which no longer likes SNA but works with UX, and xdm seems to sit
at the prompt waiting for something:
#0 0x00007f7ff344285a in poll () from /usr/lib/libc.so.12
#1 0x00007f7ff6031f3d in IoWait (wt=0x7f7fffffcec0, wf=<synthetic pointer>,
wf=<synthetic pointer>)
at /usr/xsrc/external/mit/libXt/dist/src/NextEvent.c:356
#2 _XtWaitForSomething (app=app@entry=0x7f7ff7e60000,
ignoreEvents=ignoreEvents@entry=0 '\000',
ignoreTimers=ignoreTimers@entry=0 '\000',
ignoreInputs=ignoreInputs@entry=0 '\000',
ignoreSignals=ignoreSignals@entry=0 '\000', block=block@entry=1 '\001',
drop_lock=0 '\000', drop_lock@entry=1 '\001', howlong=howlong@entry=0x0)
at /usr/xsrc/external/mit/libXt/dist/src/NextEvent.c:624
The cursor is visible in the Login: prompt, but apparently Something never
happens... (Switching to SNA, doesn't change anything.)
Thoughts on how to debug?
Cheers,
Patrick
