I used upgradepkg --install-new /my/Directory/*.tgz.
When X starts i hear startup sound, but i see only the mouse arrow on a white screen.
In /my/Directory i put all packages of KDE 3.2.2 and of XFree86 4.4.
Could be a problem about settings of fonts, icons etc?
What should i edit?

Shall i come back to previous KDE and Xfree? In this case how?

Please help me. I can not use internet without X. I am a newbie.

Hi,
I don't know about upgradepkg, but here is the method that will surely work (It worked for me many times ): you should use pkgtoll to remove all libraries related to KDE, as well as the KDE itself and the XFree. So everithing like Qt, KDevelop and other apps that are somehow related to KDE and came with the Slack9 destribution should be removed using the root console. Then use some ftp client(mc will do just fine) to connect to some Slackware mirror site (for example ftp.heanet.ie) and go to the current directory of Slackware destribution. Download and install the KDE and it's libraries, apps and everithing you need from that FTP. I installed KDE 3.2 without any problems this way.
Note, that for some reason the newly installed KDE doesn't start properly right away. You should reboot the system and then try again(you should type startx before reboot, after this fails reboot and everithing will start OK). And you also should remove the xinitrc and the KDE folder from your user directory(infact everithing related to KDE).
Hope this works for you.

Yes, it should be a good idea.
What about Xfree 4.4? I can not find it anymore.
Do you know where can i find it?
I only have the .src packages.

XFree is available at that FTP server. It is in the slackware/x directory. You should install all packages from this directory.
