Installation RedHat Linux AS4.0 after the solution of the flower screen __linux

Install RedHat Linux AS4.0 on the virtual machine, because the choice of color depth is too high when the video is configured, the 16-bit color is configured to 24-bit color, which results in a flower screen when the graphical interface is opened, and the screen width is very large, seriously deformed and unable to operate.

Since there is a problem with the Graphics configuration section, you must modify the configuration information for that section. In this case, these should go into Single-user mode to complete:

First reboot the machine, after Grub appears, press the letter "E", then the Grub configuration file appears, then press the keyboard to move the cursor to the second line "Kernal ...", press "E", and then enter single in the Edit interface, carriage return. Then press "B" to reboot and enter "Single-user mode".
After entering the prompt, type: vi/etc/x11/xorg.conf, then open the video profile, and then enter "/screen" (note s is in uppercase) to retrieve the screen section, where the relevant configuration will be displayed.

Then you press "I" key into the VI editor insert mode, the cursor moved to the "24" position, the 24 here to 16, and then press the ESC key to return to the command mode, by the colon ":", input Wq, enter, save, exit. Type the reboot command, enter, reboot, and the graphical interface comes out.

The following is the contents of a correct xorg.conf file:

# XFREE86 4 configuration created by Pyxf86config

Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "Corepointer"

    # Rgbpath is the location of the "RGB database.  note", this is the name of the
  &N Bsp # file minus the extension (like ". txt" or ". db") .  There is normally
    # No need to change the D Efault.
    # Multiple Fontpath entries are allowed (they are concatenated together)
    # by Default, Red Hat 6.0 and later now use a font server independent of
    # The X server to render fonts.

# To disable the Xkeyboard extension, uncomment xkbdisable.

# to customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a NON-U.S.
# Keyboard, you'll probably want to use:
# option "XkbModel" "pc102"
# If You are have a US Microsoft Natural keyboard, can use:
# option "XkbModel" "Microsoft"
#
# Then to change the language and change the Layout setting.
# For example, a German layout can is obtained with:
# option "Xkblayout" "de"
# or:
# option "Xkblayout" "de"
# option "Xkbvariant" "Nodeadkeys"
#
# If you ' d like to switch the positions of your capslock and
# Control keys with use:
# option "Xkboptions" "Ctrl:swapcaps"

Note The above section "screen" ... The endsection part is where we need to be concerned. In fact, the author found that defaultdepth 16 inexplicably changed to Defaultdepth 16161616161616161616. Subsection "Display" part of the two 16 are changed to 24, need to change all back. This indicates that there are 2 monitors in the case.

The author compared Redhat Linux 9.0 situation, found that the video profile is not/etc/x11/xorg.conf, but/etc/x11/xf86config (note the case of file name), this everyone must pay attention to. Xf86config section ' Screen ' ... The Endsection section is also different, as shown below, and should be related to the hardware configuration of the machine:

Section ' Screen '
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
Defaultdepth 16
Subsection "Display"
Depth 16
Modes "800x600" "640x480"
Endsubsection
Endsection
