Ubuntu Linux, ubuntu desktop, Linux operating system, ubuntu guide

1. Type gksu nautilus in Terminal and allow your group read/write access to /etc/X11 (or use the chmod commands if you prefer the terminal.
2. Type nvidia-settings into the terminal and in the NVIDIA X Server Settings window that pops up, click on nvidia-settings Configuration and then click “Save Current Configuration” and then exit the applicationThis will create ~/.nvidia-settings-rc for you. (not 100% sure this is needed)
3. Type nvidia-xconfig into the terminal. This will create an /etc/X11/xorg.conf file that does not, by default, get created in 12.04 Precise.
4. Type nvidia-xconfig — cool-bits=4 into the terminal and this will add the proper settings in your /etc/X11/xorg.conf file and back the previously created one up.
5. Reboot your machine and open nvidia-settings up with the Terminal or your dash and under your GPU heading/Thermal Settings list, you can now change fan speed.
6. I yanked mine up to 100% from 20% and my temperatures went from 47C to 35C.

Remember to change the permissions on the /etc/X11 directory back so accidents don’t happen.
Made a BASH script named FanController.sh with:

and added it to Startup Applications

In this issue machine  have the two hard drives. On one is Windows XP , on the other one is Xubuntu 12.04 .

Here the windows MBR is fine. I can boot my Windows partition by selecting that HD from the BIOS. Likewise the MBR on the other hard drive is fine and I can boot Xubuntu from grub. What I would like to do is to be able to chainload ntldr (I believe that’s the right terminology) from grub.

os-prober does not detect Windows – unless the partition is mounted but it can’t write anything anyway because it says it needs to be run as root. However sudo os-prober doesn’t seem to do anything at all, so that doesn’t help either. Always getting below error.

ERROR: you must be root ERROR: you must be root /usr/lib/os-probes/mounted/20microsoft: 47:

I have followed below steps for resolve the issue

Added the following to the lines below those already in /etc/grub.d/40_custom:

Reinstalled os-prober with the following:

sudo apt-get install --reinstall os-probe
