  Some time ago sleepwalk installed a beta version of Fedora 14, it was remorseful system instability, but found that I actually made the right choice: F14 direct support my ATI graphics card, while the current stable version of Fedora 13 is not. . . Said to be a little silly, say for a long time to install the graphics driver, we did not find that the open-source graphics drivers already fitted. .

Well not much to say nonsense, the system installed after a resolution of 1024x768, apparently still relatively low, and I hope to achieve the same under Windows 1280x800. Of course the premise is to check your video card drivers installed not otherwise be dark soon Fedora you see, oh

1. Check the video card driver is not installed
Terminal enter the command $ lspci -v
Appear long, long hardware information. Find the card that period, I was so

01: 00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3650 (prog-if 00 [VGA controller])
Subsystem: ASUSTeK Computer Inc. Device 1872
Flags: bus master, fast devsel, latency 0, IRQ 46
Memory at e0000000 (32-bit, prefetchable) [size = 256M]
I / O ports at c000 [size = 256]
Memory at fcef0000 (32-bit, non-prefetchable) [size = 64K]
[Virtual] Expansion ROM at fce00000 [disabled] [size = 128K]
Capabilities:
Kernel driver in use: radeon
Kernel modules: radeon

Capabilities that line is "Forbidden" because I did not open admin rights ...... but that does not matter. www.linuxidc.com good, according to the current situation, the graphics driver is ready, the following should officially began

2. gtf
Back to the terminal, enter the command $ gtf 1280 800 60
Of course, if you want to adjust the resolution to 1280x1024 or another, enter the corresponding command. The final figure is 60 refresh rate, the liquid crystal display 60 can then be written directly. Well we see this output:

# 1280x800 @ 60.00 Hz (GTF) hsync: 49.68 kHz; pclk: 83.46 MHz
Modeline "1280x800_60.00" 83.46 1280 1344 1480 1680 800 801 804 828 -HSync + Vsync

The second line is very important, and copy it down and keep it. The best is saved to the root directory easy to find them

3. Build Xorg configuration file
It should be restarted. After restarting the GRUB screen, press the 'E' key to edit the command in the 'kernel / vmlinuz ......' behind the line of a '3', press Enter. B Press Start. Such boot to a text console mode.
With root account login.
Enter the command Xorg -configure, it will scan your hardware configuration and generate a xorg.conf.new file, pay attention to the place where the document (the last lines have prompted program execution), followed by the job to find it
Well, not all of the command line interface embarrassed ...... In fact, I will not use vi ....... Enter the reboot, press Enter. Back to restart X graphical interface

4. Modify the configuration file
After the restart using the root login, behind permissions needed more places
Xorg.conf.new find just generated configuration file, open with gedit on the line. File is longer, but we only need to modify the following two paragraphs:
The first is the display

Section "Monitor"
#DisplaySize 300 190 # mm
Identifier "Monitor0"
VendorName "CMO"
ModelName "LCD Panel 1280x800"
HorizSync 31.5 - 90.0
VertRefresh 60.0 - 60.0
Modeline "1280x800_60.00" 83.46 1280 1344 1480 1680 800 801 804 828 -HSync + Vsync
EndSection

If a line already exists, would not have changed, I do not copy the data here. Especially the first line, with a specific monitor related.
The last three lines are generally required new, which is the last line of the second step gtf data generated from a saved file you just pasted, do not copy my Oh, Oh

The second needs to be modified later

Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
    DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x800"
EndSubSection
............

And there are very long do not have control. 6 lines after I presented here need to create, Modes field is the resolution you want, tailored to the specific circumstances.
After modification saved.

5. overwrite the old configuration files
Restart, log on to the console interface text again, log in as root

To avoid accidental to back up what the old configuration files. Enter the command cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak000
Attention to the case. X11 x11 written word is not enough.
Go to your store xorg.conf.new with cd directory, and then enter the command cp xorg.conf.new /etc/X11/xorg.conf
Prompted to overwrite, press Enter to enter y.
Enter the reboot, press Enter. Restart

6. appreciate the new graphical interface.
