I’ve had a weird issue. My Kubuntu install would never start Xorg. I could boot to recovery, then make it “resume normal boot”. But it would never boot on its own. I pinned the issue on graphics drivers.
My Graphics Processor is Nvidia GeForce 8400 GS
Latest Ubuntu 32 bit display driver (as of Jan 23, 2012)
This downloads a 32 MB executable file NVIDIA-Linux-x86-290.10.run
Boot to Ubuntu recovery, navigate to the folder containing NVIDIA-Linux-x86-290.10.run
First install binaries required to rebuild kernel:
sudo apt-get install build-essential[/code]
Then install the driver:
sh NVIDIA-Linux-x86-290.10.run[/code]
Now you can start X with:
sudo /etc/init.d/kdm start[/code]
Add Nvidia module to start with
kdesudo kate /etc/modules[/code]Add a line "nvidia" on a new line
Once Nvidia drivers are installed, you can configure them with:kdesudo nvidia-settings[/code]For more instructions, refer the following:
