X Server on AIX w/o video card
Post 3273 by sam_pointer on Thursday 28th of June 2001 04:39:13 AM

I welcome a kicking if I am wrong but I think that the terms have become confused here.
You would think that the X 'server' would be the box running the X apps, wouldn't you? As in "file server". But this is not the case. An X server is a process which 'displays' X programs. Therefore the X server is the machine actually displaying the program.
Therefore the last post would stand to reason now that we have clarifies the terms. Of course you need a graphics card to run an X server, otherwise you wouldn't be able to see anything.
You do not need a graphics card to execute X programs however - so yes, the AIX box does not need a graphics card to execute the code - but the Sun box must in order to run the X server to display the output of the AIX box.
Very confusing!!
I think the confusion comes from applying client-server networking terminology to X. One instantly thinks " I'm connecting to the [AIX] box, therefore it is the X server ".
Hope this is clear(er)

Hi everyone.
I'm looking for a way to extract the video card properties (Name, Driver version, amount of vram). I've managed to deal with nVidia cards, but nothing came for ATI/AMD cards and other kind of chipsets. Can someone point a way to do this?
Thanks. (4 Replies)

Xserver(1) General Commands Manual Xserver(1) NAME
X - X Window System display server dispatcher SYNOPSIS
X [ option ...] DESCRIPTION
: Hewlett-Packard supports two X servers on HP-UX platforms, the Xhp X server which supports HP VISUALIZE graphics devices and the Xf86 X server which supports all other graphics devices. These X servers are delivered as /usr/bin/X11/Xhp and /usr/bin/X11/Xf86. The X dispatcher determines which X server to launch based on the available graphics devices. The control file /etc/X11/Xstart can provide additional guidance to the X dispatcher. The control file allows the user to specify which X server to start for given display connection numbers. The only X servers supported by the X dispatcher are Xhp, Xf86 and Xvfb. If no Xstart file exists, the dispatcher loads the appropriate X server for the graphics device in the system. HP-UX does not deliver the /etc/X11/Xstart file. This file can be created by using the SAM/SMH utility. OPTIONS
If the X dispatcher is invoked with no arguments, the display connection is assumed to be :0. The X dispatcher checks for display connec- tion options and, if found, uses that display connection number when it checks the Xstart file. All other options are passed on to the X server when it is started and it is the X server's responsibility to validate these options. Not all options may be supported on both X servers; refer to Xhp(1) and Xf86(1) to verify supported options for each X server. RETURN VALUE
None Xstart EXAMPLES The control file syntax is the X server to start followed by the display connection number. Valid entries take the form of: Xhp :0 Start the Xhp X server on display connection 0 Xf86 :10 Start the Xf86 X server on display 10 /usr/bin/X11/Xhp :5 Start the Xhp X server on display connection 5 /usr/bin/X11/Xvfb :7 Start the X Virtual Framebuffer server on display connection 7 FILES
/etc/X11/Xstart Dispatcher control file. /var/X11/Xserver/logs/Xstartup.N.log X dispatcher log file for display N. SEE ALSO
