Intel Integrated Video Card resolution adjustment tool 855 resolution

Article Title: Intel integrated graphics card resolution adjustment tool 855 resolution. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems and open source, and other basic categories. 855 resolution is a dedicated tool for adjusting resolution of Intel integrated display cards; according to the introduction, the 855 display card is used for notebook integration;

I. 855 Application Scope of resolution;

View the 855resolution instructions to learn:

This software changes the resolution of an available vbios mode. It is useful, when the native screen resolution isn' t advertised as available by the video bios by default.

If the resolution of the machine fails or the machine has to be adjusted again after the machine is restarted, use this tool to adjust the resolution;

Ii. installation and configuration of 855 resolution:

1. Install 855 resolution

In Fedora Core 4.0, if you use the yum online update package, see linux.chinaitlab.com/set/39828.html "> Fedora/Redhat online installation and update package, yum. to view how to use yum and the software warehouse;

[root@localhost beinan]# yum install 855resolution

In Fedora Core 4.0, if you use apt to update the software package online, see linux.chinaitlab.com/unix/39857.html "> online installation or upgrade of Fedora core 4.0 software package with apt + synaptic. to view apt usage and software repository;

[root@localhost beinan]# apt-get install 855resolution
2. Application and configuration 855 resolution

855 resolution is installed in the following directory. All files are as follows:

[root@localhost beinan]# rpm -ql 855resolution
/etc/rc.d/init.d/855resolution
/etc/sysconfig/855resolution
/usr/sbin/855resolution
/usr/share/doc/855resolution-0.4

[root@localhost beinan]# 855resolution --help
855resolution version 0.4, by Alain Poirier
Usage: 855resolution [-p] [-l] [-f bios_type] [mode X Y]
  Set the resolution to XxY for mode
  Options:
    -l display the modes found into the vbios
    -f skip the VBIOS detection by forcing a VBIOS type
    -p display the registered plugins

First, we will list the vbios mode: Use the-l parameter;

[root@localhost beinan]# 855resolution -l
855resolution version 0.4, by Alain Poirier
Chipset: 855GM (id=0x35808086)
VBIOS type: 2
VBIOS Version: 3360
Mode 30 : 640x480, 8 bits/pixel
Mode 32 : 800x600, 8 bits/pixel
Mode 34 : 1024x768, 8 bits/pixel
Mode 38 : 1280x1024, 8 bits/pixel
Mode 3a : 1600x1200, 8 bits/pixel
Mode 3c : 1920x1440, 8 bits/pixel
Mode 41 : 640x480, 16 bits/pixel
Mode 43 : 800x600, 16 bits/pixel
Mode 45 : 1024x768, 16 bits/pixel
Mode 49 : 1280x1024, 16 bits/pixel
Mode 4b : 1600x1200, 16 bits/pixel
Mode 4d : 1920x1440, 16 bits/pixel
Mode 50 : 640x480, 32 bits/pixel
Mode 52 : 800x600, 32 bits/pixel
Mode 54 : 1024x768, 32 bits/pixel
Mode 58 : 1280x1024, 32 bits/pixel
Mode 5a : 1600x1200, 32 bits/pixel
Mode 5c : 1920x1440, 32 bits/pixel
Mode 7c : 1280x768, 8 bits/pixel
Mode 7d : 1280x768, 16 bits/pixel
Mode 7e : 1280x768, 32 bits/pixel

Through the content listed above, for example, if I want the display to support 1024x768 32 bits/pixel and check that its Mode is 54, we should use 855resolution to set it;
[root@localhost beinan]# 855resolution 54 1024 768

The above is a command line configuration, preferably the most convenient configuration file; the 855resolution configuration file is/etc/sysconfig/855 resolution;
# Mode to overwrite (use "855resolution -l" to see all available modes)
MODE="54"
# Resolution to set (i.e. "1280 768", no "x", only a space as the separator)
RESOLUTION="1024 768"

After modification, restart/etc/init. d/855 resolution. Next time you start the machine to enter the system, you don't have to worry about it. It is a self-starting service;

[Root @ localhost beinan] #/etc/init. d/855 resolution start
Overriding video bios mode 54 from 1024x768 to 1024x768: [OK]

In addition, you must modify/etc/X11/xorg. conf to view a section similar to the following;
Section "Screen"
        Identifier "Screen0"
        Device "Videocard0"
        Monitor "Monitor0"
        DefaultDepth 24
        SubSection "Display"
                Viewport 0 0
                Depth 24
                Modes "1024x768"
        EndSubSection
EndSection

If we use 24 as the default color depth, the resolution in the 24-color SubSection "Display" should include 1024x768 as mentioned above. Just for example; of course, you think that the machine can support 1280x1024, you can also use the previous method to configure it, and then write it in xorg. conf;

Iv. Appendix:

Some useful help, such as gtf usage; NVIDIA and ATI display card driver installation;

Postscript:Most display devices are supported, such as displays and display cards. However, there are still few officially produced display card drivers. Currently, only NVDIA and some ATI display cards have drivers. With the driver, you can play the 3D function. Come on ......
