Need an help for booting and desktop manager


Hi there
I am new in this forum and I am here for some questions I have.
First of one: I have installed Debian Squeeze installed all I need to have my desktop (kde) working, but after loading all necessary for that purpose when start 'kdm' my screen become unreadable.
Many verticals lines blinking.
I can't do anything and every time I want to reboot I am pushed in kdm (as default desktop manager). I don't now how I can manage this problem and I suppose all depends from my graphic card (nvidia 6800GS ),

Any help?

thank you.

Hya,

I remember that I ran into similar problem in the past.

If you can ssh in to that machine, you can kill kdm without much trouble.

I guess that ctl-alt-BS does not help much, however, it may kill kdm.

If you still have media which you used to install Debian, use that one to boot, then escape to shell, do your necessary job.

Happy Penguins!

How did you do this? What was the "all necessary" of which you speak?

Do you have other DMs installed?

ctrl+alt+F1 - should get you a text login.

When you do get to a text login, take a look at /var/log/Xorg.0.log --chances are that X is not starting correctly because you need to install a driver for your video card.

Also look at /etc/X11/xorg.conf to see what driver is being specified. One thing to try is specifying the "vesa" driver to see if that gets you running.
The relevant section of xorg.conf will look something like this:
Code:
Section "Device"
        Identifier  "Card0"
        Driver      "radeon"
        VendorName  "ATI Technologies Inc"
        BoardName   "Radeon RV200 QW [Radeon 7500]"
        BusID       "PCI:1:0:0"
EndSection

I did this:
  • aptitude update
  • aptitude safe-upgrade
  • aptitude install xorg
  • aptitude install kdm

Therefore I was pushed to choose one desktop manager and debian take me up to kdm, but no way

Yes, I have thoungt it was this problem, but time ago when I got to use debian the installer take me into the comnfiguration file for X server. Now?
I have saved one file from my previous installation. Coul I paste it into te new one? Or is better to rename the original file e create a newone with these lines?
