Ubuntu is very hot, so I am going to install an NVIDIA driver this morning. The NVIDIA driver was installed in Debian before, and the graphic interface cannot be opened. This is also the reason for giving up Debian (the resolution is 1024 × 768, which is quite uncomfortable ). After reading a few tutorials, these materials are also available on the Ubuntu Chinese website, but the version is old, which is 11.10. Although it is only one version different from the 12.04 version I used, but there are still some differences. The driver is still relatively new from the NVIDIA official website. It was updated eight days ago (think of Linus's use of NVIDIA, haha). According to the online tutorial, it is easy to install successfully. Restart, messy, with a resolution of 640x480. The NVIDIA driver does not seem to take effect, but the "yes" parameter specified during driver installation should have been changed. I want to manually change the resolution, and I found that only 640*480 is used. I think it should be Intel's set-display driver. Find a solution on the Internet. Some people say that the set display is disabled in the BIOS options. After a restart, it looks messy. There are only two options (Lenovo v470
This version cannot be installed with the release version of The RedHat series). One is to use dual-display, and the other is to use only set-display. No way. I uninstalled the NVIDIA driver, restored the configuration (previously backed up), restarted it, and finally came back. Thank God. Then, Bumblebee is installed to disable the unique display, which significantly reduces the heat production.
Bumblebee installation method:
Sudo add-Apt-repository PPA: Bumblebee/stablesudo apt-Get update after installation: sudo apt-Get install Bumblebee bumblebee-NVIDIA
