Re: GLX acceleration
Yes, XWin_GL seems to run OK, though I have not seen any dramatic speedup yet. It is likely that part of this may be due to memory problems I seem to be having in the latest xorg downloads, with XWin and now also with XWin_GL. (I only seem to have these problems in xterm and rxvt, not in a Cygwin console window.) `dired` (below) freezes and other processes i other xterm windows bomb: 19:25:05 @lester:~% top C:\cygwin\bin\tcsh.exe (472): *** fork: can't reserve memory for stack 0x3 - 0x23, Win32 error 487 6 [main] -tcsh 2808 sync_with_child: child 472(0x67C) died before initialization with status code 0x1 3423 [main] -tcsh 2808 sync_with_child: *** child state waiting for longjmp No more processes. 19:26:38 @lester:~% pkill -9 dired --8<-- top cut 1/2 -> bottom 1/2 --->8-- Subject: Re: new Cygwin has memory problems?

GLX acceleration?
In an effort to get better performance on my ThinkPad/XPPRo I'm considering adding the "experimental" GLX acceleration module offered under setup. Is anyone using this? How do you turn it on? Thanks. Lester

Re: WMaker 0.90 broken?
Well, it does seem to be a font issue. I used setup, and did a re-install of a couple of x11 font packages and everthing seems to be working just fine. On a side note, ipc-daemon2 does not seem to provide whatever is needed by MIT-SHM, as I get that message, whether I have ipc-daemon2 started or not. I also think it's not a goodness that using setup to handle an upgrade breaks the fonts package(s) and causes system failures But then, that's just my opinion, and as we all know, opinion are like rear-ends Everyone has one, and they are usually all full of ..

Problems after move to Windows 2003 domain
A month ago I had cygwin working perfectly. Then we upgraded to a Windows 2003 domain. I still have the same XP work station but now when I run startx cygwin crashes with errors about the clipboard. I have tried disabled the shared clipboard feature and the X server will now come up. I can run xeyes fine. However when I try to run xterm the CPU load on the Xserver goes straight to 100% and stays there. I have done an strace on xterm and I can see it is waiting on a read from the tcp socket to the X server, after 20 minutes the Xserver sends it data and up it comes. I have tried a variety of other programs and they all behave like xterm (except xeyes). I don't have any idea how to go about working out what it is doing. Can anyone help? Tim P.S. Since the domain move I have rerun mkpasswd and mkgroup, it didn't make any difference. I have also upgraded to the latest cygwin with the online installer; again it made no difference.
Problem Starting Xterm
Hi, I have just installed cygwin on WIN XP, with the all xorg packages installed. But not the xfree86 ones because they say removed package beside them - which I take to mean they are deprecated? Anyway by using either startxwin.bat startx or startxwin.sh, the xwin program starts and has the black X in the system tray it doesn't seem frozen as I can toggle hiding it if I want, but no xterm starts, and when I try to manually start one using just the command xterm the response is: "xterm Xt error: Can't open display:" Could someone help me with this?

It has to be ssh trying to execute some system(..) call prior to opening the
connection, and the problem is with the command in question; that's hanging up,
openssh is waiting for it to complete boom! Although I'm not familiar with
the source code and haven't studied it (and 'grep' is _not_ a source analysis
tool!), nonetheless a quick grep lends at least some support to this hypothesis:
[EMAIL PROTECTED] /usr/src/openssh-3.9p1-2> grep -w sh *.[ch]
auth.c: * legal, and means /bin/sh.
defines.h:# define _PATH_BSHELL "/bin/sh"
pathnames.h: * /bin/sh before starting the shell or command if they exist. They
will be
session.c: * legal, and means /bin/sh.
sshconnect.c:* Use "exec" to avoid "sh -c" processes on some platforms
[EMAIL PROTECTED] /usr/src/openssh-3.9p1-2>
That comment in sshconnect.c looks highly significant to me!
You could probably strace openssh, then find out what parameters sh.exe is
being called with, and see if sh.exe shows the same behaviour when you try the
same command from a prompt. I think the problem that needs tracking down will
turn out to be with the commands that openssh is relying on sh to execute,
rather than anything intrinsic to openssh itself.
Actually strace probably isn't necessary. I see lines like this
debug("Executing proxy command: %.500s", command_string);
and oh look! like this!
/*
* Run $HOME/.ssh/rc, /etc/ssh/sshrc, or xauth (whichever is found
* first in this order).
*/
static void
do_rc_files(Session *s, const char *shell)
{
FILE *f = NULL;
char cmd[1024];
int do_xauth;
struct stat st;
do_xauth =
s->display != NULL && s->auth_proto != NULL && s->auth_data != NULL;
/* ignore _PATH_SSH_USER_RC for subsystems */
if (!s->is_subsystem && (stat(_PATH_SSH_USER_RC, &st) >= 0)) {
snprintf(cmd, sizeof cmd, "%s -c '%s %s'",
shell, _PATH_BSHELL, _PATH_SSH_USER_RC);
if (debug_flag)
fprintf(stderr, "Running %s\n", cmd);
f = popen(cmd, "w");
which make me think you ought to just be able to run ssh with some debug options
on the command line, and that ought to give you enough information to find out
what's wrong. Try "ssh -v -v -v " and see what that tells you.
cheers,
DaveK
