I upgraded my laptop to Jaunty Jackalope. Here’s the list of issues (and solutions) I’ve run into:
1. Tor is not packaged anymore, apparently there is no Ubuntu maintainer. Upstream provides Ubuntu packages, but they have no jaunty package yet. So, we need to build from the intrepid source package. Add
deb-src http://mirror.noreply.org/pub/tor intrepid main
to your /etc/apt/sources.list, and
apt-get update cd /usr/src apt-get build-dep tor apt-get source tor -b
2. Bug 270046: Apparmor *still* fights with cups-pdf. This one’s been around since the Hardy days. You’d think it would be fixed by now… Specifically, print jobs to the PDF printer will just vanish because apparmor does not allow cupsd to save them in ~/PDF. Solution: disable apparmor for cupsd:
apparmor_parser -R /etc/apparmor.d/usr.sbin.cupsd /etc/init.d/apparmor restart
3. Bug 339555: Intel video is really really really really slow. Case in point: workspace switching takes seconds. (Partial) fix: upgrade to a experimental 2.6.30rc3 kernel. Even with that kernel, video performance on this GM965/GL960 based system is still not what it should be. To be continued, no doubt.
5. Sound has been an issue on this laptop from day one. It’s a Dell inspiron 1420N that shipped with Ubuntu preinstalled, but at the time a special Dell-supplied kernel was necessary to get working sound. The sound hardware is
$ lspci -vnn 00:1b.0 Audio device : Intel Corporation 82801H (ICH8 Family) HD Audio Controller [8086:284b] (rev 02) Subsystem: Dell Device [1028:01f3] Flags: bus master, fast devsel, latency 0, IRQ 21 Memory at fe9fc000 (64-bit, non-prefetchable) [size=16K] Capabilities:
Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 0/1 Subdevice #0: subdevice #0
First of all I had to add my user to the pulse-rt group – pulseaudio was complaining loudly about that in /var/log/syslog. That’s a Jaunty upgrade bug.
Secondly, for some reason I can not get sound to work until I unload the snd_hda_intel module and reload it. Sadly, that means closing all applications that are using the sound hardware – mpd, firefox, pidgin, the gnome volume control applet, etc. I don’t know what’s causing this, but I had the same problem on Intrepid after the last kernel upgrade. Again, to be continued.
