Kubuntu black screen

[Joubert]

today i reinstalled Kubuntu on a completely formatted partition. Installation is fine but when i get to boot, after choosing to boot kubuntu on the grub menu the screen goes totally black as to load the kernel, but then stays black forever. Xserver problems? How do i solve? I have no clue. trying to fool around on dpkg-reconfigure xserver-xorg didn't help. I hope some of you will. Thanks in advance. I have a Geforce 8800 gt and a samsung lcd screen.

Re: Kubuntu black screen

When you ran "sudo dpkg-reconfigure xserver-xorg", did you select the "nvidia" or "nv" driver? The problem probably lies with your current driver settings; if you chose "nvidia", try it again selecting "nv" instead. If neither the "nv" nor "nvidia" drivers work, run the command again and choose "vesa", which is compatible with all cards and should definitely work. Let me know how it goes.

I tried the vesa thing. Then reboot, then i start linux from grup and it say something similar to
starting kdm ............................[Ok]
etc............................................[Ok]
.
.
.
.
.
loading local script rc...............[Ok]

at that point i can only press ctrl alt F2 to start a konsole. I typed
sudo /etc/init.d/kdm start and it said kdm was already running. But how do i get to a desktop then?

Re: Kubuntu black screen

Something is misconfigured with your Xserver (X.org). Try the command "sudo dpkg-reconfigure xserver-xorg" with the "-phigh" argument; it should look something like this:

sudo dpkg-reconfigure -phigh xserver-xorg

You may also want to stop KDM with the command

sudo /etc/init.d/kdm stop

Then, run "startx" and see if you get a GUI; if not, make sure you've exited KDM, and run the command

sudo Xorg -configure; sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak; sudo mv ~/xorg.conf.new /etc/X11/xorg.conf

And run "startx" again.

Edit: I modified the command a little.

The Nvidia 8000-series are kind of tricky to get installed and working correctly. Best advice is to download and run the Envy driver installer, from here. You want the file "0.9.9-0ubuntu6" which is part way down the page.

Here are some further tips, based on my 8800GTS:

I want to thank you for that tidbit of info. I was in Kubuntu and installed the nvidia-glx-new files. When I rebooted all I got was the shell screen, no gui.

Went looking for answers and yours rang a bell. Followed the instructions and now I'm able to select the resolution that I want and Ubuntu booted into the gui.

The only problem is that it booted into the Gnome desktop instead of KDE.

But it is progress..

At the login screen, you can select which session type (KDE, KDE 4, Gnome, etc.) you want to boot to by clicking the drop-down menu on the bottom-right, selecting "Session..." (don't remember exactly what it's called ), and choosing which session you want.
