Unlock greyed out in Ubuntu when using nx(nomachine)

leave a comment »

I was trying to use the “services-admin” application over a nxserver (nomachine) connection and the Unlock button was greyed out. This was the same for the “Users and Groups” button as well.
Solution was to run “polkit-gnome-authorization” and select org->freedesktop->systemtoolsbackends … and setting “Anyone” and “Console” to “Admin Authentication”.

Issue logged here;

ITV3 and ITV4 didnt work on mythTV

leave a comment »

I only recently noticed that ITV3 and 4 were not working following the national retune earlier in the year. turns out that there were duplicate entries in the channels table. The listings were still being shown when scheduling programs, but the Program Guide always showed as “Unknown”.

i stuck a suffix on the channel name field in the database using mysql-query-analyser so that I could identify them in backend setup. I then used backend setup to delete them.

dont bother with cheap RAID cards (in Win XP)

leave a comment »

After loosing data a couple of times a few years back i decided that I would keep everything on RAID1 (mirrored) discs.

the options that i had (under Windows) were either;

  1. Use Microsoft Dynamic disks.
  2. Buy a cheap RAID card.

Option 1 looked like it would only work if I had Win Server, so I went for option 2.

Now I have found that the RAID set is constantly being rebuilt and the system has become slower and less reliable.

A safer (because that is what you really want) option is to do some straight-forward copying. I got hold of MS SyncToy 2.1 and set it up as a scheduled task – problem solved…
