hello folks i cant get xdm to run properly on a host which serves for a couple of xterms. previously, i was running 3.3.6 and had no problem. however when i upgraded to 4.2.0, xdm freaks out and keeps trying to redraw screens on the server machine, never getting past the stippled background before switching modes and trying again. i can see that the process is running, and xdmcp is listening on udp 177, but the xterms cant find it when they broadcast for clients. when i run "startx" or just "X" on the central host machine, everything works fine: i get a session, kde will start (or whatever other x program i like), etc. the machine is a freebsd 4.6-RC box, fairly old hardware and a pretty generic video setup. from dmesg: FreeBSD 4.6-RC #4: Tue Jun 4 11:57:43 PDT 2002 jeff@filer:/usr/src/sys/compile/FILER Timecounter "i8254" frequency 1193182 Hz CPU: Pentium II/Pentium II Xeon/Celeron (400.91-MHz 686-class CPU) ... pci1: <PCI bus> on pcib2 pci1: <SiS 530/620 SVGA controller> at 0.0 irq 10atkbdc0: <Keyboard controller (i8042)> at port 0x60,0x64 on isa0 atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0 kbd0 at atkbd0 psm0: <PS/2 Mouse> irq 12 on atkbdc0 psm0: model IntelliMouse, device ID 3 ... vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0 sc0: <System console> at flags 0x100 on isa0 sc0: VGA <16 virtual consoles, flags=0x300> ... also after running xdm, this shows up in messages (im assuming its related to the mouse): psmintr: out of sync (0000 != 0008). psmintr: discard a byte (1). from /var/log/xdm-error: XFree86 Version 4.2.0 / X Window System (protocol Version 11, revision 0, vendor release 6600) Release Date: 18 January 2002 If the server is older than 6-12 months, or if your card is newer than the above date, look for a newer version before reporting problems.
