Linux on HP 2510p

informations about running Linux on HP 2510p

If I have the choice, I only use small and lightweight laptops - I can't understand, how one can like the normal size, 3 kilos bricks (in German I call them "Schlepptop"). It is not always simple to find a machine with standard compliant components in this size. But there are good products on the market and good linux distros, which can manage nearly every need of a mobile computer user. Before buying the new laptop in April 2008 (the last machine was a IBM Thinkpad X31) i was using (open)Suse for several years. It was great (e.g.: uptime of about 300 days - no reboots, only s2ram with APM, he he), but after 4 years the batteries becomes old and it is not possible to buy original parts for my x31 in Germany...

So I was looking for a good linux machine under 1,5 kilos (ca. 3 pounds). The HP Compaq 2510p is certified for SLED, so I gave HP the chance (my last compaq - Armada - is from the year 1998 and still working as backup-machine and router with debian - in defiance of mineral water shower...). But with openSuse 10.3 I was a little bit disappointed, because power management wasn't working out of the box. I guess it was to solve with some tricks, but I've used the occasion to try something new. I got kubuntu 8.04 beta and I was impressed, how good it was dealing with the machine. Installation was done in 35 Minutes, little problems (described on this page or linked here) were solved in minutes too. So I'm with Kubuntu on HP 2510p now.

On this page I try to collect all informations about configuring this machine. My conclusion is: Linux is improving very fast and kubuntu on this little HP is a charm.

Problems with closing laptop lid (freezing in several cases)

Solutions are discussed here: And in short: the solution is to do as root:
echo 1 > /proc/acpi/video/*/DOS

(Little) problems with the wireless-driver (iwl4965)

Kubunty Hardy Heron (beta) installs wireless on the 2510p without any trouble and it works out of the box.

The only thing is, the laptop has an on/off-wireless button, which runs me into some problems. This button turns on and off the wireless card and the bluetooth-module on the machine and helps saving energy, if no wireless is needed. Sometimes the wireless driver doesn't come back after turning the wireless on with the button. It looks for me, as the driver hangs and I can't remove that until reboot. Because I never reboot a linux machine (i do only suspend), it isn't a solution for me.

My workaround at the time (I don't know, if it works, but until now there where no problems) turning on and off the wireless looks like this:
- off: 1) pressing the button 2) doing modprobe -r iwl4965
- on 1) pressing the button 2) doing modprobe iwl4965
network manager does the other necessary steps.
