Not being one to "fix it if it ain't broke", I was impelled over this
past weekend to finally upgrade my Ubuntu Studio box from 9.10 (Karmic,
which is now unsupported) to 10.4 (Lucid/LTS). Things actually went
pretty smoothly, with only a couple of issues after the upgrade reboot.
1. Upon initial login, my Gnome UI's windows were missing the title-bar
decoration, which meant that I couldn't move or resize windows(!).
After a bit of puzzling about this, I right-clicked on the desktop
background to bring up "Change Desktop Background", went to the "Visual
Effects" tab, changed the setting from "None" (somehow [re]set by the
upgrade) to "Normal", clicked Close -- and windows were a-ok again.
2. More vexing than the above: I now see that my (sound) Volume Control
app (pavucontrol) dies repeatedly after "some long use" with a
"Connection failed: Connection refused" error box. This is repeatable,
but I cannot find the cause yet. Attempts to click on the menu-bar icon
to restart the app just give me another "Connection refused" box,
until...
I can get things restarted with the following com-line:
$ pulseaudio & pavucontrol
This gives yet another "Connection refused" error box, but after
dismissing this, the menu-bar icon works again. For awhile...
Anyone got any experience with this problem? And a good, permanent fix?
I've checked my resources, esp. Ubuntu Forums (Studio threads, etc.),
but all I'm getting there is a lot of noise and conjecture, not much
authoritative help.
TIA for any wisdom, experience and/or helpful advice...
best regards,
