I broke the cardinal rule and updated to software that was only 1 day old. It seems I’ve been reasonably lucky and very little went wrong. I thought I’d better write some notes on what did go wrong just in case it happens to someone else and they lose a day trying to work out how to put them right.<\/p>\n
This would have been quite amusing if it had been the only problem. There isn’t much space on my workbench, so I put a 1280×1024 LCD panel behind and above my laptop’s 1280×800 panel, and extend my desktop up from the laptop. When the Ubuntu distribution upgrade had finished, the desktop was the wrong way round. I had to mouse up from the big panel to get to the bottom of the laptop panel. I tried editing xorg.conf and running aticonfig, and reverting to the pre-upgrade xorg.conf, but nothing seemed to fix the problem. In the end, I installed the ATI control panel with:<\/p>\n
apt-get install fglrx-control<\/p><\/blockquote>\n
and that allowed me to set the correct desktop layout.<\/p>\n
Distribution Upgrade didn’t use proxy<\/h3>\n
I’m not complaining about this one. We’ve just terminated our ADSL contract because it’s so unreliable, so we’ve only got ADSL until the notice period expires. If you’re a Streamyx user, I will soon no longer be sharing your pain.<\/p>\n
On our home network we’ve got Streamyx ADSL on an ADSL router and a DiGi EDGE adapter on a server connected by ethernet to the same router. The server runs a squid web proxy to try to reduce the load on the nominally much slower EDGE adapter. We configure synaptic to use the web proxy for updates. It works a treat for updating Ubuntu on our PCs in the house, but the dist-upgrade didn’t seem to use the proxy settings in synaptic \/ update-manager at all. I’ll have to think of some other way of updating the other PCs in the house, I don’t want to repeat the 1GB+ download over EDGE!<\/p>\n
File reporting .jar files (Java archive) as application\/zip<\/h3>\n
Now this one really was annoying. I have a few Java projects that are bundled up as Java archives. I can just double-click on the .jar file in my file browser (ROX), and they would usually be launched with java -jar<\/strong>. After the 8.10 upgrade, the ‘file’ utility was reporting them as application\/zip, so double-click was launching file-roller! I tried all sorts, even renaming all associated files and copying older versions from a PC at home running Hardy which reported the files’ type correctly. Nothing.<\/p>\n
I’m embarrassed to say I don’t know which of the last two solutions I tried actually solved the problem. After trying to destroy any chached mime types by removing ~\/.local and running the ‘update-mime’ utility, the problem went away. My Java archives are now correctly identified by file. If you have the same (or similar) problem, I’d appreciate a comment to say which one solved the problem for you.<\/p>\n
General impressions of Intrepid Ibex<\/h3>\n
Apart from the problems above, things seem to be running very smoothly. I’m interested to see how Network Manager has changed – it has never really given me the impression of being ‘finished’ in the past. As I look at it now, I see it says my laptop is disconnected from any network. The wireless kill switch seems to be working as I’d expect: too bad I rarely move my laptop away from the wired network on my desk!<\/p>\n","protected":false},"excerpt":{"rendered":"
