This morning I did a little experiment to compare which one more fast, my PC or my laptop (my office’s laptop exactly 😀 ). It’s really dummy experiment by the way. I’ve tried to run Ubuntu 7.04 Live CD on both computer.My PC is spesifications are Intel Pentium IV 2,66 GHz with 512MBmemory installed. No additional graphic card used, just using onboard graphic card. My laptop is Fujitsu S Series with Intel Pentium Mobile inside; it has 1,6 GHz processor speed. It has same memory size with my PC, 512 MB.

With my cellphone as stopwatch, I write down that my PC run Ubuntu faster than my laptop. Since boot until desktop ready to use, it just need 2 minutes and 15 seconds. My laptop need more time, it’s need 4 minutes and 9 seconds.

Before run this dummy experiment I guess that both of them will need same time to run live cd Linux. The reason I thought like that because two computer have some memory size. But I was wrong, in this situations (two system have same memory size) processor speed was take more responsibility to system performance. He..he..he..really a dummy experiment.

Maybe there are some other factor that I didn’t measure in this experiment, like optical drive speed and total hardware inside the system. Optical drive speed should gave impact to system that run live cd operating system, because all part of operating system was lay on cd. Total hardware that installed in the system maybe become another factor, more hardware will cause OS need more time to recognize each of them. My laptop have more hardware like bluetooth adapter, wireless adapter, firewire, modem.

So I think it’s not fair to say that my PC is more faster than my laptop if we count two last factor that I explain above. For conclusion let say if two system have same configurations except processor speed, we can guess system with faster processor will running live cd operating system more fast than the other one.

Last night I reinstall OpenSUSE in my laptop (you can read here for background story).

Today in office I tried to install Yahoo Messenger again in my OpenSUSE. From information I read last night, Yahoo Messenger for Linux is suspect for problem like that. Just for make you understand, yesterday when I installed Yahoo Messenger for Linux, I didn’t reboot my laptop until I went home. So that I just realized that my Linux crashed when I was in home. This afternoon, as soon as I finished install YM, I reboot my laptop….guest what? Same problem came back.

Thanks Gods, I found several good posts in Internet that discuss about problem like one I have…see here and here for example. From several source, I tried to take conclusion : I think at least there are 3 step that can save me from reinstalled my Linux 😀

1. Delete file .ICEauthority and file .xinitrc on my home directory.
   # cd /home/tedy
# rm .ICEauthority
# rm .xinitrc
2. Delete /tmp directory and create another one :
   # su - root
# rm -rf /tmp
# mkdir /tmp
# chmod 1777 /tmp
3. Run sax2 tool for reconfigure X86Config file.
   # su - root
# sax2
4. Restart X session manually using this command :
   # su - root
# rcxdm restart
5. After X session appears, I reboot my laptop and when it came up I could login successfully into my OpenSUSE.
6. To make sure that OpenSUSE was fine, I tried to reboot my laptop several times. Until now, it running well.

Yahoo Messenger for Linux create .xinitrc file for make YM start when Linux startup. This one the root cause of these problem. Thanks for all you guys that share your experiences and your skill in the Internet ^:)^ .

Two days ago, I tried to install OpenSUSE 10.2 on my office’s laptop. It was running well, this afternoon I also use this OS for some work in office. When I came home from office, I got stuck with some trouble with my OpenSUSE. When I login I couldn’t enter GDM. After enter username and password, no desktop environment loaded. It just black console screen. Error messages that appears like this :

Your session only lasted less then 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or that you maybe out of diskspace. Try logging in with one of the failsafe sessions to see if you can fix this problem.

I tried to figure out what is the problem, almost 4 hours I tried all method which I got from Google. After several trial and errors, I gave up 🙁 . I copied all the data into Windows partition. After that I reinstalled OpenSUSE. When I write this post in my PC, installation still running (now run on CD 5).

But I read one article on Internet that explain about Yahoo Messenger for Linux can cause problem like one I have. This is what I must learn more : X server configurations.

ps : this is my first post in English since 9 month blogging :))
