Những câu hỏi thường gặp về Linux
X Window System
H:
Linux có hỗ trợ X không?
Đ:
Yes. Linux uses XFree86 (the current version is 4.0, which is based on X11R6). You need to have a
video card which is supported bởi XFree86. See the XFree86 HOWTO for more details.
Most Linux những bản phân phối nowadays come with an X installation. However, you can install or
upgrade your own, from ftp://metalab.unc.edu/pub/Linux/X11/Xfree86-* và its mirror sites, or from
http://www.xfree86.org/
.
H:
Làm thế nào để X Window System hoạt động
Đ:
The answers to this question can, và do, fill entire books. If the installation program wasn’t able to
configure the X server correctly, Linux will most likely try to start the X display, fail, và drop back into
text-only terminal mode.
First và foremost, make certain that you have provided, as closely as possible, the correct information to
the installation program of your video hardware: the video card và monitor. Some installation programs
can correctly guess a “least common denominator” screen configuration, like a 640-by-480
VESA-standard display, but there are many possible video hardware configurations that may not be able
to display this standard.
The X Window System configuration file is called (usually) [/etc/XF86Config], [/etc/X11/XF86Config],
or [/usr/X11R6/lib/X11/XF86Config].
If you need to manually configure the X server, there are several possible methods:
•
Try to use the XF86Setup program, which can help identify the correct X server và monitor timings
for the video hardware.
•
Make sure that the X server has the correct options. If you log in as the superuser, you should be able
to use
X --probeonly
to get a listing of the video card chipset, memory, và any special graphics
features. Also, refer to the manual page for the X server. (v.d.;
man X
), và try running the X server và
redirecting the standard error output to a file so you can determine, after you can view text on the
screen again, what error messages the server is generating; v.d.,
X 2>x.error
.
•
With that information, you should be able to safely refer to one of the references provided bởi the
Linux Documentation Project. ("Where can I get the HOWTO’s và other documentation? ") There are
several HOWTO’s on the subject, including a HOWTO to calculate video timings manually if
necessary. Also, the Installation và Getting Started guide has a chapter with a step-by-step guide to
writing a [XF86Config] file.
Also, make sure that the problem really is an incorrect [XF86Config] file, not something else like the
window manager failing to start. If the X server is working correctly, you should be able to move the
mouse cursor on the screen, và pressing Ctrl-Alt-Backspace will shut down the X server và return to
the shell prompt in one of the virtual terminals.
