Display Catch-22
If this is a re-posting, my apologies. The original was reported "Mail
Delivery Failed" and did not appear in the list I downloaded. In
another case I re-posted a message after receiving the "Mail Delivery
Failed" notice, the re-posting did appear when I downloaded the list and
there was a response to the re-posting telling me that the original
was posted to the list. I have reconfigured exim and hope this solves
the problem.
My Belkin UPS probably saved my computer from the power surge but its
internal programming is probably fried. I reinstalled the software from
the Linux tarball changing all the ownerships to root:tom and all the
permissions to 770. This allows me to display the monitor but I cannot
change the setup. When I originally installed the UPS I did all this as
root and was able to change the setup. This is no longer possible as
security changes do not allow me to open a display as root.
The only thing to change is the com port which I was certain I had right
in the first place. To be sure I uninstalled the programs and
reinstalled them changing from /dev/ttyS0 to /dev/ttyS1. Neither works
though /dev/ttyS0 retrieved some information but in either case the
installed software generates periodic messages that the UPS device is
unreachable. This is what makes me believe the UPS internal software is
fried.
Before replacing it I would like to be sure that the display problem is
resolved. I have searched the X11, xdm and icewm setup files trying to
remove the restriction preventing opening a display as root. My plan
would be to take the computer offline (The connection is wireless so
ifdown wlan0 does this) during the time the root prohibition is overwridden.
Any suggestions?
