Debian Wheezy

RootMason · 05-23-2013, 02:47 PM

Hello all! I just installed Debian Wheezy (net installer) from CD and on boot there is no usable screen, just a bunch of white & black lines. Installed on a Dell Optiplex 740 and tried hooking it up to several different monitor that all work. Same effect. Loads GRUB just fine, begins loading then goes crazy and never recovers. Any options? I will disable gui if I have to, but I like it for using web browsers!

Any help you can give will be much appreciated! Thanks in advance for your time.

Does the problem occur then you try to startx or before that?

Code:

$ lspci

Tried disabling gdm3 by booting to the recovery console and using:

update-rc.d -f gdm3 remove

No effect, screen remains unusable.

Thanks for the response, buddy! It goes crazy just after choosing the kernel to run. I have to boot to the recovery console to get anything.

The results of lspci are in the attachment lspci3.jpg attached to this response. Sorry, I am having to troubleshoot this from my laptop! Again thanks for the help!!

I would head for the BIOS setup first and ensure that you've allocated enough shared memory to the VGA.

If that doesn't help, then you will probably need to the proprietary nvidia driver. I'm not a grub/grub2 user so I can't help much, but at the grub boot screen, edit the kernel line and boot with the nomodeset parameter to disable kernel mode setting

Then follow this guide and install the nvidia proprietary driver: http://wiki.debian.org/NvidiaGraphic...n-free_drivers

Your system uses the Geforce 6150 integrated videochip, which is known to have many problems with the free nouveau driver. Install the proprietary driver from the repositories and you should be fine.
