Upgrading Ubuntu Gutsy to Hardy
Posted by Jim Morris Sun, 13 Jul 2008 11:32:03 GMT
I did my duty and upgraded from Gutsy to Hardy, after letting Hardy settle for a while. For the most part it was painless (unlike the last upgrade to Gutsy!).
Unfortunately the sound was now broken I have a HDA-Intel AD198x Analog chip set.
Then I discovered (just when I needed it of course) that my Samsung ML-2010 USB printer didn't print anymore.
I would get this weird error...
Unable to open device hal:///org/freedesktop/Hal/devices/...
After Googling I found this, he was half right, I don't know why but it works, except that I needed to do...
sudo chmod 700 /usr/lib/cups/backend/usb
sudo chmod 700 /usr/lib/cups/backend/hal
sudo killall -HUP cupsd
sudo /etc/init.d/cupsys restart
ie both usb and hal.
That fixed it... Amazing!
Now why won't my audio work???
Ok now it does work, go figure. The only things I changed were added this to /etc/modprobe.d/alsa-base
options snd-hda-intel model=3stack-dig
and made sure that Front was checked in the mixer and turned up.
Not sure which of those fixed it though.
Suuuuuuper, I had the same bullshitty thing, and that's really fixed it, Im sooo glad, thank you!!! :)
... well... I was full right :) My hal already had these permissions without any action done by me.

Yea,thanks that really saved me, except my hal was not set right so when I initially tried your suggestion it didn't work, so I got side tracked turning off apparmor, reinstalling cups etc. Then for some reason I wondered if the hal permissions was the problem and it was.
I wish I knew why this worked though. I suspect it was because I upgraded from Gutsy and the permissions were set wrong there.
Without your Blog it would never have crossed my mind to try that, what made you think of that?
