New computer, fresh headaches

As you who read this reasonably often will know already I work with computers, computer systems and information systems.

From my point of view Linux is the best choice of operating system and laptop is what I must use. Laptop because I travel a lot, a "netbook" does not quite cut the mustard, ever so smart phones do not either as the infrastructure in the countries I work does not really offer enough connectivity and I want to use quite a few applications not (yet) available via phone systems.

The currently popular tablet computers with touchscreens leave me rather uninterested, I need more screenspace and more power than what an ever so slick tablet computer offers.

So after I once more found myself as consultant I decided to buy a new laptop. My "old" Dell is used at home by Mia, the even older Dell by the kids and the one I was using belonged to the former employer. I was allowed to keep using it but did not feel all comfortable with that arrangement.

As a friend/colleague/partner was arriving from Sweden I asked him to buy and bring a computer for me. Did some research and ended up with a HP Pavilion dm4.

In my experience Dell, HP and IBM/Lenovo are the best brands (ok maybe Sony Vaio but you pay through the nose then) in terms of reliability, service and so on. They also normally work well with Linux instead of Windows. I was a bit unhappy with some minor issues with the Dell I had at work last so decided to try this HP instead.

It is just to admit it: I did not do enough homework. Only after it arrived did I discover it has this new "switching" graphics with 2 systems, one for when you are on power and the other for when you are on battery.

"Only" problem is that this is poorly supported in Linux so far. So boy have I struggled to get that sorted. Some computers have a function where you can via setup (bios) switch off one or the other. Not this one, to be honest it is the most useless bios system I have ever seen. Not to mention that an upgrade of it (bios) actually made wireless internet stop working, both in Windows and Linux... NOT what I am used to from HP.

OK have that sort of under control now. But things like screen "dimming the lights" when power goes does not work (I have to do it manually) and I can not switch off the stupid fingerprintreader I don't see myself using. And and and.

And just like the last Dell it gets uncomfortably hot for having in/on your lap. The new processors seem to give off considerably more heat than the one I have in my "trusty old Vostro" that Mia is using. The difference is not small, from around 35 C to 55-60 C. NOT too nice with sweaty lap when sitting on the sofa (like now).

And I HATE the new touch/clickpad that does not have separate click buttons. Both in Windows and Linux it is a nuisance and I can only pray that better drivers will make it work better "next version".

Of course it is faster, better screen, more memory, larger disk, has webcam (that I never use..), is lighter and so on. But somewhere along the line of development certain things that I really like from the old Vostro are sadly missed.

Going back is not an alternative though (Mia keeps suggesting we swap if I am not happy) as all that I crammed on the disk now will simply not fit on the older computer...

One upgrade too many

My life naturally consists of lots of upgrading and testing software on computers. Not least my own where I often want to test something out.

Well, you can go too far... a couple of weeks ago I decided to test a "release candidate" of the linux desktop environment KDE, version 4.5 RC2 to be more specfic.

One thing that I suspect caused headaches later was that the upgrade was disrupted at least 2 times due to our sometimes ver slow internet.

When all was supposedly done I rebooted and stared at a black screen. No graphics, only terminal commandline login. Oooops. Big time.

I can not even remember how I finally managed to get back to a working graphical interface but I found x number of half or nonworking applications. Had to give up and reinstall an older version. A working one! Luckily I have since looong made sure that all user data is on its own partition and will normally not be messed up by experiments like this.

This once more proves the old truth: do not mess with your working/production computer. Test new stuff on another one - but how many have an extra computer lying around? Not me, at least not one that is not being used.

Lesson learnt: do wait until final release...

Computers and Mana Pools

Just a comment on the sometimes somewhat weird world that happens to be my profession. As I work on my laptop that has Kubuntu Linux as OS I sometimes need to run various versions of Windows for support reasons. I do this by running something called VirtualBox - an environment where I can run other systems "inside" my Kubuntu main OS. That way I have Windows XP Pro, Windows Server 2003 and Windows Vista installed and can run them without rebooting.

Currently I am testing out next version of Kubuntu Linux, "Karmic Koala", to be released October 2009. And I find it so good that I write this, visit Facebook, chat and check one of my (many...) email lists from within the pre-release of Karmic. So I sort of swap between my main version and the new depending on what I am doing...

Otherwise I am really looking forward to go to Mana Pools next weekend for the annual Game Count. Feel in bad need of a break.
