Well, congrats! So it was a bad burn.

I do not use Gnome, so i'm not familiar with it's prog.s, I use KDE. not sure if it's the same but ctrl+alt+del will change mouse curser to skull n Xbones you can click on the window you wish to kill. In KDE ctrl+esc gives you Ksysguard- a list of running procc.s with size and cpu % and ability to kill.

To try a diff window manager such as KDE or WindowMaker, just install via YaST (for kde select all it prog.s) then with yast select 'security and users' ->'user management'-> then 'expert options' select 'login settings' and deselect 'Auto login'. now when you boot you will have to select user and supply password and in lowere left corner you can select the window manager i.e. Gnome, KDE, WindowMaker etc. depending on what you have installed.

To find more about Gnome try Gnome.org or gnome-look.org .

Don't forget to do an update, look on opensuse.org for a list and how-to for online sources.

cheers mate thanx for all your help.

I have two hardrive. hda is entire for XP partitioning.
hdb is for linux. Including several linux OS for testing.

When I install opensuse. It eat my hda 136.2GB space. I thought is, how big is the OS. And I check the Yastz,

/dev/sdb1 15GB Linux native
/dev/sdb2 2GB swap
/dev/sdb3 70.5MB Linux native
/dev/sdb4 136.2GB Linux LVM
/dev/system 136.2GB LVM2 system
/dev/system/home 25GB
/dev/system/root 20.0GB

Can I keep the system in minimum usage of my HardDrive 160GB

P.S.
/dev/sdb1 15GB Linux native
/dev/sdb2 2GB swap
Is for ubuntu

And
/dev/sdb3 70.5MB Linux native
/dev/sdb4 136.2GB Linux LVM
/dev/system 136.2GB LVM2 system
/dev/system/home 25GB
/dev/system/root 20.0GB
Is it opensuse maybe? I am not sure

I have already try Yaast to resize but it is not allow me to do

Any expert who can help thx for your assist

looks like following happened
/dev/sdb3 70.5MB Linux native
This is probably mounted as / , which is way more space than you need , the only problem is that this one I do not think it will allow you to resize while mounted.
do a df -k and verify as I am guessing , based on the fact that suze normally installs on a non lvm partition.
/dev/sdb4 136.2GB Linux LVM
/dev/system 136.2GB LVM2 system
/dev/system/home 25GB
/dev/system/root 20.0GB
The VG system has been given a 136.2 GB partition of the disk (probably all the remaining space ?)
90 GB of that is not allocated (free within vg), two lv's have been created , they are probably mounted as /root and /home.
If you wan't your space back for additional installs of linux , the best bet without getting too complicated is probably going to be the following
copy the data in the /home and /root fs (I am guessing here , change to whatever they are actually mounted as ) to a temporary dir IE /root.tmp and /home.tmp
unmount the two filesystems (if one is in use you will have hassles at this point)
cp -pR /root.tmp/* to /root/. and cp -pR /home.tmp/* to /home/.
vi /etc/fstab and hash out lines mounting /dev/system/home and /dev/system/root.
reboot
go to yast system lvm
deletete filesystems ,delete lvols then delete vg.
This will leave /dev/sdb4 136GB partition as unallocated space which you can use as you wish with a 70GB suse install.
BTW this is still 7 times more space than you should need for normal os purposes.

Your info are very useful. |I think, as a newbabe. I simple way is to re-install step by step. After you advise me to back up. If 150GB HD. Can I deploy use 10GB for opensuse10.2. LVM deploy several partitioning

Another useful online source for learning linux, I have a long way to go with linux....

By the way, I am appreciate with your reply in professional explaination.
