Hello, Here is the setup. I am running two different desktop computers, each with their own monitor, but with only one keyboard / mouse. I am using a Belkin KVM switch to control the keyboard / mouse function between the two. The switch has USB inputs and USB outputs. I am running Fedora10 (F1)0) on each desktop computer. Each has a different NVIDIA Quadro card installed, and I am running NVIDIA drivers (different version of each because the one card is not supported anymore). Everything works fine, until I launch OpenOffice on either computer. At that point, when I use the KVM to switch mouse / keyboard to the other desktop X will crash. I have not been able to reproduce this with anything other than the OpenOffice suite of applications. It has something to do with the evdev module.... here is the backtrace in the Xorg.0.log (EE) Belkin Corporation Flip CC: Read error: No such device (II) config/hal: removing device Belkin Corporation Flip CC (II) Belkin Corporation Flip CC: Close (II) UnloadModule: "evdev" (EE) Dell Dell USB Keyboard: Read error: No such device (II) config/hal: removing device Dell Dell USB Keyboard (II) Dell Dell USB Keyboard: Close (II) UnloadModule: "evdev" (II) config/hal: Adding input device Belkin Corporation Flip KVM (**) Belkin Corporation Flip KVM: always reports core events (**) Belkin Corporation Flip KVM: Device: "/dev/input/event3" (II) Belkin Corporation Flip KVM: Found 5 mouse buttons (II) Belkin Corporation Flip KVM: Found x and y relative axes (II) Belkin Corporation Flip KVM: Configuring as mouse (**) Belkin Corporation Flip KVM: YAxisMapping: buttons 4 and 5 (**) Belkin Corporation Flip KVM: EmulateWheelButton: 4, EmulateWheelInertia: 10, EmulateWheelTimeout: 200 (II) XINPUT: Adding extended input device "Belkin Corporation Flip KVM" (type: MOUSE) (II) config/hal: Adding input device Belkin Corporation Flip KVM (**) Belkin Corporation Flip KVM: always reports core events (**) Belkin Corporation Flip KVM: Device: "/dev/input/event7" (II) Belkin Corporation Flip KVM: Found keys (II) Belkin Corporation Flip KVM: Configuring as keyboard (II) XINPUT: Adding extended input device "Belkin Corporation Flip KVM" (type: KEYBOARD) (**) Option "xkb_rules" "evdev" (**) Belkin Corporation Flip KVM: xkb_rules: "evdev" (**) Option "xkb_model" "pc105+inet" (**) Belkin Corporation Flip KVM: xkb_model: "pc105+inet" (**) Option "xkb_layout" "us" (**) Belkin Corporation Flip KVM: xkb_layout: "us" Backtrace: 0: /usr/bin/Xorg(xorg_backtrace+0x26) [0x4e7a26] 1: /usr/bin/Xorg(xf86SigHandler+0x39) [0x47a679] 2: /lib64/libc.so.6 [0x33dac32f90] 3: /usr/bin/Xorg(XkbStringText+0x1c) [0x56711c] 4: /usr/bin/Xorg(XkbWriteXKBGeometry+0x191) [0x5587d1] 5: /usr/bin/Xorg(XkbWriteXKBKeymapForNames+0x5bb) [0x557d1b] 6: /usr/bin/Xorg(XkbDDXLoadKeymapByNames+0x18a) [0x561cba] 7: /usr/bin/Xorg(ProcXkbGetKbdByName+0x3ab) [0x53fb2b] 8: /usr/bin/Xorg(Dispatch+0x364) [0x4468d4] 9: /usr/bin/Xorg(main+0x45d) [0x42cd1d] 10: /lib64/libc.so.6(__libc_start_main+0xe6) [0x33dac1e576] 11: /usr/bin/Xorg [0x42c0f9] Fatal server error: Caught signal 11.

Also, the other box is not 64bit, but I can recreate the exact results by doing the same procedure. 1) log in, 2) open openoffice, 3) use KVM to switch mouse/keyboard control to the other box -- Rediscover the Web <a href="http://www.mozilla.com/firefox/">http://www.mozilla.com/firefox/</a>
