[XFree86] X window session timeout through firewall
CheckPoint NG firewall We have some X sessions through some clustered NG firewalls that will drop. We don't want to put a generalized config to increase the TCP timeouts for any X related ports, and have that apply to *everyone* using those ports. Is there some kind of way to have the client keep sending some type of keep-alive to keep the X sessions up? The users claim that they are continuously using their sessions, but they still timeout. I haven't read up on X enough to figure out if it works at all like FTP with control sessions (where the control session might stay idle for long amounts of time, during a big download, for example). We will soon be getting some network sniffers to see what's going on. Any ideas? Marco ___ XFree86 mailing list XFree86@XFree86.Org http://XFree86.Org/mailman/listinfo/xfree86

Re: [XFree86] SM722 design with multiple controllers

This is a replacement board for an older design using 4 ChipsTechnology CT69000 devices. Our target system uses 8 video controllers driving 8 LCD panels in a multi-player gaming system. The target operating system is Linux, using XFree86. I am having some difficulty getting the multiple controller system working. I can get a single SM722 evaluation board to start X correctly, and I have also had success getting a dual monitor system to work using the SM722 eval board as the primary display, then using a ChipsTechnology board as the secondary display. However, if I reverse this order and install the CT board as the primary, then the SM722 as secondary, X fails to start correctly. I have attached XFree86 log files for these two cases. I have also attached a log file where two SM722 controllers were installed. Here is a summary of my testing: 1. SM722 Primary Display, ChipsTechnology CT69000 Secondary display - Log file XFree86.SMprimaryCTsecondary.log. Both displays worked fine 2. ChipsTechnology CT69000 Primary Display, SM722 Secondary display - Log file XFree86.CTprimarySMsecondary.log. XFree86 failed and crashed with the following result (excerpted from log): ((WW) Silicon MotionCannot read colourmap from VGA.

Will restore with default (II) Silicon MotionSMI_GEReset called from smi_driver.c line 1579 (II) Silicon MotionSMI_GEReset called from smi_accel.c line 263 I would appreciate some help in debugging this problem, along with any suggestions you may have. Well, I'm no expert in Silicon Motion hardware, but a -logverbose 4 log (with an SM722 as secondary) might provide a clue. There are also a couple of shots in the dark you can try: 1) Add Option NoUseBIOS to SM722 secondary screens; 2) Change SMI_PreInit() to not get rid of pSmi-pInt10 before returning; 3) Uncomment SMI_PreInit()'s calls to xf86SetOperatingState(). Thanks, and good luck. Anything more on this?

Re: [XFree86] X starts when mouse is not connected (AllowMouseOpenFail = false)
Sorry Marc, I've been a little bit busy with other things lately.
In regards to the change, I could only find it on line 150 of
posix_tty.c where the code is:
SYSCALL (fd = open (dev, O_RDWR | O_NONBLOCK));
if (fd == -1)
{
xf86Msg (X_ERROR,
xf86OpenSerial: Cannot open device %s\n\t%s.\n,
dev, strerror (errno));
xfree(dev);
return (-1);
}
I've made the change and as I write this it's building. I'll let you
know what happens when I've tested it (hopefully today or tomorrow),
Lance
