In the first article, we declare that the perfect solution for low resolution after installing ATI graphics card on Ubuntu 10.10 is referred to in this article, but the application environment of this article is Ubuntu 10.04 @ Nvidia graphics card.
My machine Configuration:
ASUS F8Vr; Intel Core Duo T8300; ATI Mobility Radeon HD 3470; VRAM: 256 MB; 14 "WXGA
1. Problems to be Solved:
(1) After the driver is installed, the screen is displayed on and off, with a low resolution;
(2) The Boot screen appears directly, and the progress is missed.
2. Solution: uvesafb replaces vesafb
3. required packages:
(1) v86d (required by uvesafb)
(2) hwinfo (view framebuffer)
4. Solution steps:
(1) install the driver
System-system management-additional driver
(2) installation package:
Sudo apt-get install v86d hwinfo
(3) view framebuffer
Sudo hwinfo -- framebuffer
My display resolution is 1024x768, so what I need is: 1024x768-24
(4) modify the grub file (the purple color is the modified one)
Sudo gedit/etc/default/grub
