I decided to bite the bullet today and upgrade my fujip from breezy to dapper, using the graphical update manager.

The actual upgrade went without a hitch - it asked me a couple of times to replace conf files I’d modified manually, but everything worked fine during the upgrade.

Post-upgrade, I had to do the following:

• Manually install network-manager as my custom pkgs were auto-removed - this was fine as I got the latest “real” packages
• Fix widescreen
• I was using 855resolution for the built-in Intel video, which has been merged/upgraded to 915resolution. The fix was as easy as apt-get install 915resolution.
• Fix the audio, wireless, and PCMCIA
• This was my fault - the default kernel was still set to my “custom” 2.6.12 from breezy, so none of that worked. I fixed /boot/grub/menu.lst and all that stuff “just worked”. :)
• Rebuild the kernel
• This is because of my EVDO card - the usbserial module needs patching. Rather than just roll the module, I build the whole kernel - mostly cause I’m too lazy to figure out how to make a .deb of just the module. One day I’ll spend the time to figure that out.

So as far as I can tell, the system is running well. I’ll have to poke at it some more, but I think the upgrade went relatively smooth, compared to my upgrade headaches in the past.
