Phew, arch really isn’t nice to me in the last days.
But there are not only negative things to mention, e.g. I got my network working using these two arch-wiki pages as reference:
Network_Profiles
WPA_supplicant

But.. actually.. the problem now is that I did not manage to make them connect automatically via netcfg, yet. But I have to admit that, for now, I didn’t really try it too hard because I do not have that huge amount of free time due to my studies.

Anyway- a much greater problem is the, what I think it is, xf86-video-intel driver issue. It makes my X freeze all the time- randomly as it seems. I did remove powerdevil and cpufreq from my system because I thought this might be a problem but it actually still occures and makes it impossible working with arch.
That is why I commented on a bug here.
There seems to be already a newer version of the video-intel driver, which is version 2.6 (not yet available in the repos). Let’s hope this will be the fix..

Sad but true: my Linux is just like Windows right now!

UPDATE:
The freezes have been “fixed” for me. It turned out that kwin desktop effects were responsible for those errors. Some ppl. report that using a libdrm from AUR is allowing you to turn on 3D-effects again but I rather wait for a new official version to come out since I can live with no desctop effects for some time.

I just got my sound working after several hours of trying. To save you time and trouble, here goes a tutorial on that:

Install alsa-utils and alsa-lib if they are not already present on your system.
Run # alsaconf then and follow the steps through the configuration.

Now the important part: Add this line to your /etc/modprobe.conf
options snd-hda-intel probe_mask=1

Now, make your sure your user is added to the group audio
# gpasswd -a user audio

You might want to reboot after the last three steps instead of manually loading all the modules now.

After rebooting, go in your konsole, log in as root and start # alsamixer.
Make sure your PCM, Master and Front channels are not muted (toggle with ‘m’).
BUT: your Analog L channels have to be muted!
I can not tell you why so, I just found it out via trial-and-error.

Your sound should now be working! If you still got some issues with your sound, check the very good Archlinux Wiki – ALSA page.

Thanks to fettouhi for sharing his solution at the archlinux forums!

Two days before, I luckily managed to get most parts of my Arch 64bit up and running on my Latitude E4300.
As I do have a WPA encrypted Wireless connection at home, I first tried connecting to the wireless-lan here at university. It worked at the first try (Tutorial to come).
After that I tried getting rid of my messed up (automatically created) xorg.conf and started deleting around 50% of all lines. In the end I set defaultcolordepth to 24 and the resolution to 1280*800 and – hooray – it worked, too! Playing around with the newly acquired desktop effects was rather fun.

Anyway- the next thing I got handle now is the problem with the encrypted wireless at home, because
iwconfig essid "WLAN-Name" key s:PASSWORD
does not work and says something like “…unable to set…”.
Using the iwlwifi-5000-ucode firmware, I do not know if this might be a software related problem or not, so I have to figure that out, I guess.

Stay tuned~

did you know?
Sleeping less than 7 hours a night greatly increases the chance of catching a cold and flu!

A research team of Carnegie Mellon University, USA, found out that sleep and the immune system are closely linked. Dr. Ron Eccles, director of the Common Cold Centre at the University of Cardiff said:
“The immune system may control the sleep-wake pattern and lack of sleep or sleep disturbance may depress the immune response to infection.”
