1,440 symbolic links
The tree /etc/X11/xserver contains 720 symbolic links. The vast majority of of them are locale specific and point to the directory /etc/X11/xserver/C. The only thing in /etc/X11/xserver/C is a tree called print. The tree /usr/X11R6/lib/X11/xserver seems to be identical to /etc/X11/xserver. My question is: can I get rid of all those symbolic links? The reason that I ask is that I'm using Fergus' instructions for building a CD from which cygwin can be run (http://www.cygwin.com/ml/cygwin/2003-07/msg01117.html). Because ISO-9660 file system does not support symbolic links, the technique for handling them is to create copies of everything that is symbolically linked. For /etc/X11/xserver that means about 998 MB of disk on an ntfs file system with a respectable blocking factor. /usr/X11R6/lib/xserver also takes up that much space. My hope is that X has a respectable default, something like if localization file can't be read, use /etc/X11/xserver/C (or /usr/X11R6/lib/xserver/C). Or, maybe /etc/X11/xserver/C/print really is for printing (the tree seems to contain printer specs), and if I don't want to print, I can get rid of it all. I've tried poking around at X.org, but can't seem to find documenation tha's appropriate. I'd be grateful for any of the following: - simple answer such as delete with impunity - it doesn't matter - point me to appropriate documentation - point me to appropriate sections of the source code.

It is not behaving like linux in that once you get an EOF on a read using stdio, you get EOF forever after. I've made a cygwin-specific correction to the newlib library to make cygwin work more like linux. I will generate a cygwin snapshot sometime soon which should have a fix for this problem.

Re: GLX acceleration
Lester, Exactly what kind of speedups are you expecting here? AFAIU, the GLX-accelerated XWin will give you speedup only for programs that use the GLX extension, which automatically excludes most standard X clients (e.g., xterm, emacs, etc). For applications not using the GLX extension, the GLX-accelerated XWin should be no different from the regular XWin. Alexander, please correct me if I'm wrong.

Reconnect to X session
Hi all, Searched the mailing list for this FAQ but no joy, so here we go How can I reconnect to a Cygwin/X server created X session started on a Linux server (Debian Sarge) ? How I currently connect ? From my XP desktop, open Cygwin Bash Shell Type X -broadcast Get the KDM log in screen from the Linux server (only Linux server on our LAN) Log on fine and everyhting works (except for the clipboard but that's no big deal) Problem Sometimes my wireless network temporarily dies and so my laptop loses connectivity to the LAN. This breaks the connection to the X session open on the Linux box and leaves an open X session on the Linux server that I can't reconnect to. Also, sometimes I need to leave the office and take my laptop with me. This forces me to close the X session on the Linux box, thereby terminating all apps running there. I want to be able to connect, disconnect reconnect the same as VNC. I can, and do use, VNC however the issue is that the Linux box runs at 800x600 due to an old monitor while my XP Pro dekstop runs at 1900x1220. I want/need the higher resolution. TIA
