Until a few weeks ago, I had Kubuntu running on my Acer Aspire 5630 laptop (as described here), and was more or less satisfied. It looked great, hardware support was satisfying, but I was missing the incremental package upgrades that I was used to on Debian (so that things break one small piece at a time, not everything at the same time when you do an upgrade). When, after upgrading to gutsy, the laptop would lock up every few minutes for a minute or so, I thought it was a Kubuntu problem and took it as the reason to setup Debian instead. BIG MISTAKE!!!!
After I had Debian installed, I realized how bad Debian's Laptop support really is:
So, in short, I now have a laptop without properly working WLAN, no suspend and hibernate, and no support for the additional multimedia keys. Wait, what were my reasons to buy a laptop? Right, I wanted it for mobile usage, where I'm connected via WLAN, and simply open it, work two minutes and suspend it again...
I'm now starting to understand why some people say that Linux is not ready for the masses yet. If you are using Debian, it really is not ready, while with Kubuntu, all these things worked just fine out of the box (after I simply fixed the DSDT).
If having to recompile your own kernel every time it is upgraded is the price to pay for running Debian, I'm more than happy to switch back to KUbuntu again (which will cost me another weekend, which I simply don't have right now). The KUbuntu people seem to have understood that good hardware support is way more important than following strict principles (since the kernel devs don't include the dsdt patch, the Debian people also won't include it, simply because it's not in upstream... On the other hand, they are more than happy to patch KDE by self-tailored patches and cause bugs by these patches!!!).
