Error: Cannot install nvidia 195.* driver on Lucid

Some lucid kernels loads kernel module fbcon on start up, causing custom nvidia driver installation to error out. Following excerpts from ubuntu forum prevents fbcon from being loaded on startup, allowing user to install custom nvidia driver successfully:

Re: Cannot install NVIDIA 195.x drivers - installer crashes
found this and fixed most of my problems.. now I have static on one tuner though..
New Steps:

Startup your system and either get to a console from the GRUB menu or boot to Ubuntu in low graphics mode and open a terminal once it's up. Once up, type the following command

sudo pico /etc/default/grub

Once inside of the file, search for this line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

right before the last ", put vmalloc=256M, so that the line looks like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=256M"

Then, hit CTRL+O and ENTER, and then CTRL+X. This will bring you back to the terminal. At this point, we need the startup system to reconfigure itself, so we type the following command
sudo update-grub

Now, reboot the system

**NOTICE** If this doesn't work, try putting 192M instead of 256M. This has been reported to help as well.

• Remove semaphores

  sudo ipcrm -s 163840
  sudo ipcrm -s 98305
  sudo ipcrm -s 196610
  sudo ipcrm -s 294915
  sudo ipcrm -s 327684
  sudo ipcrm -s 425991
  sudo ipcrm -s 458760

• Viciously-fast bash way:

sudo ipcs -s | tail -n+4 | cut -f2 -d' ' | sudo xargs -n1 ipcrm -s

• Restart Gazebo

Error: Gazebo segmentation fault

Solution:

• Try running Gazebo with GDB to obtain a backtrace.

Error: Gazebo Compile Error

Solution:

• If one of the gazebo dependencies (use rospack depends1) has moved, you can manually remove CMakeCache.txt and recompile, or

  roscd gazebo
  make clean
  make

Error: Gazebo Dependency Ogre Runtime Error

Error

• Failed to initialize Ogre: OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic
  library RenderSystem_GL. System Error: RenderSystem_GL.so: cannot open shared object file:
  No such file or directory in DynLib::load at OgreDynLib.cpp (line 80)

  See this post for more details

Solution

• Make sure all previous versions of ogre are uninstalled.
