Ditching Ubuntu 64-bit

Since upgrading to Ubuntu 10.04 64-bit my PC became unstable. Most of the time it was just innconveinent minor things. The clock on the top panel wouldn't display properly. However occasionally the whole PC would freeze. Especially when under a heavy work load. Couple this with the fact that Adobe Flash and Adobe Air have never worked to satisfactory degree. I decided it was time to go back to a 32-bit world.

What I had to consider was what I was losing and what I was gaining. My PC has 8GB of RAM. Normally on a 32-bit system 3.75GB is as much as you get. So I'd potentially be losing half of my RAM. But that was it. None of the software I use is exclusively 64-bit. Some of it is however exclusively 32-bit and there are ways around the 4GB memory cap in 32-bit operating systems.

What I stood to gain was a simpler installation procedure for my 32-bit only software and a more stable operating system. I use the 32-bit version of Ubuntu 10.04 on my laptop with no problems. So I already knew it was more stable.

To get past the 4GB memory cap, I intended to install the server kernel which has PAE technology enabled by default. However I found this was totally unnecessary. The desktop kernel in Ubuntu 10.04 comes with PAE support.

In the end up I now have a more stable PC. A simpler installation procedure for my 32-bit software. I still get to use 7.9GB of the total 8GB of RAM in my PC. Which is actually an improvement over the 64-bit version of Ubuntu. The PC does however feel a little sluggish at times. Particularly when launching applications. But that's a small price to pay for simplicity and stability.

Ubuntu 9.10: 64-bit Installation

Okay so I've just installed Ubuntu 9.10 (Karmic Koala) to my desktop. It's not going great.

The first attempt was an "in place upgrade". The reasoning behind this was simple. I had a lot of notes in Tomboy Notes that I didn't want to lose. Previous experience has taught me that Tomboy Notes doesn't deal with upgrades well. However Ubuntu One has a Tomboy Notes synchronisation feature. So the reasoning was simple. Do an inplace upgrade. Upload my notes. Do a clean install later if I need to.

After the in-place upgrade was done I noticed the PC was very unresponsive. minutes pass by while I wait for the top panel menus to respond. I don't know what the issue is. But the 32-bit version running on my laptop doesn't suffer from this problem. But hey! No problem. I thought I'd just do a clean install. Same problem!

Now admittedly I did preserve my home directory. So perhaps there's some sort of conflict with my old settings. So my next plan of action is to wipe the system clean and start completely fresh. If that doesn't work I'll install the 32-bit version. Perhaps the 64-bit copy is experiencing issues? Who knows.

It's not all bad though. I have an SLI setup. Previously this would mean I'd have to use the text based installer. But this time the standard live CD handled my dual graphics cards with no issues. The installer can even deal with RAID arrays like Nvidia Stripe. It will even offer to install Ubuntu to the RAID array.

Considering very little seems to have changed on the desktop, RAID and SLI support in the installer would suggest all the big changes (if there are any) in Ubuntu 9.10 have taken place under the hood.

Edit 08-11-2009: As I suspected some settings from my previous installation were causing issues. With a 100% fresh install everything seems to be working fine. My advice is, do a 100% completely fresh install. Remember to back up your /home directory first and anything else you don't want to lose.
