Ubuntu8.04 configure the video card and resolution after installation

After Ubuntu8.04 is installed, the configuration method is different from 7.10. Than the previous command sudodpkg-reconfigurexserver-xorg. Not now. The resolution can be changed after logon, but it is a personal setting. The resolution when xorg is started is not suitable. I have a 17-inch flat display, and it's hard to see the words on half of the screen. Manually modify/etc/X11/xorg. conf, which does not have any default options, and must be manually added. Then add it. At the beginning, only horizontal and vertical scans were added.

Manually modify/etc/X11/xorg. conf, which does not have any default options, and must be manually added. Then add it.
At the beginning, only the horizontal and vertical scan frequencies were added (only this item was manually modified at 710). After the restart, the appropriate driver was not found, so you can manually select or add the driver. Dizzy
Finally, the Controller terminal is overwritten with/etc/X11/xorg. conf of 7.10. Everything is OK.
Leave nothing to say. paste the/etc/X11/xorg. conf of 7.10 to save the trouble of finding it later.
