Hi All,
***
Please excuse me if this is already a known problem, but I have
looked at FAQ's and haven't found anything directly pointing to a
resolution or known problem.
***
I have found on my SMP box that if I start a 2nd X display
(startx -- :1) and I switch back to :0 (cntrl-alt-F7) with X display
:1 still running that the mouse control goes hay wire. Usually when
I move the mouse left I get pull down menus, move up goes left, that
sort of problem. It appears that this is a SMP issue because this
problem does not arise on a uniprocessor config on the same box or on
like Uni processor boxes I have access too.
This problem is intermittent, i.e. not always 100% reproducible.
My experience is 50/50 encountered problem.
I have verified as much as possible that this is not a XFree86
problem (on a Uni-CPU setup XFree86-3.3.3.1, 3.3.2 are OK) and
I have made sure that gpm is not running to limit interference from
that process (if any).
If I stay in the latest started X display (:1), mouse control is assured.
If I shutdown X display :1 and return to :0 mouse control is OK.
It is only therefore, when I start a new X display and return to the
former X display that the problems appear. On a Uni-CPU I was able to
test out to :10 (i.e. 10 X displays concurrently without problems).
Any suggestions ?
O', kernel 2.2.4 & 2.2.5. PPro SMP 150Mhz, 128MB, BusLogic + 10Gb,
serial MS standard mouse on /dev/ttyS1 and as mentioned
XFree86-3.3.3.1-1.1. I have tried 2.1.190, 2.2.1 all with same issue.
Is there anything I can use to "tee" the /dev/mouse & driver
interruptions to see what is going on, and narrow this issue down
a little ?
Thanks, Grahame.
