Here's a strange one. Just curious if anyone has ever come across anything similar.
My combined desktop/server at home, an older P4 with 2 GB of RAM running 32-bit FreeBSD 8-STABLE from a few weeks ago, locks up every couple of weeks for whatever reason. No biggie, everything always come back after a reboot. Until last week.
I have a generic USB keyboard and mouse plugged into an IOGear 2-port USB KVM+audio switch. At the POST/BIOS screens, the keyboard works fine. At the FreeBSD loader screen, the keyboard works fine. At the console login prompt, the keyboard works fine. At the KDM4 GUI login prompt, the keyboard works fine. As soon as the GUI loads, the keyboard stops working.
Once the GUI is loaded, the only two key combinations that work are CTRL+ALT+F1 and CTRL+ALT+Backspace. Every other key press just causes the cursor to blink without printing any characters. Even Shift+key doesn't work.
*HOWEVER*, if you press CAPS lock, then all the keys work, and one can use SHIFT+key to get small letters.
Switching the KVM to the laptop, every key on the keyboard works at all times.
So, thinking it was something to do with Xorg keyboard driver, I reinstalled the X keyboard port. No change.
Thinking that enabling HAL would help, I reinstalled the Xorg server port with HAL support, and enabled the Auto/Empty input options in xorg.conf. Restarting X, the keyboard started to work again.
3 or 4 days later, the system locked up again (really need to track down whether it's heat-related). And now the keyboard only work when CAPS lock is enabled.
I've played around with keyboard layouts and whatnot in KDE. I've played around with keyboard options in xorg. I've disabled HAL support in the X server. I've even swapped USB ports around. And it's still not working.
But, the keyboard works fine at the console, and when connected to the laptop.
Anyone ever come across something like this? Anyone have any hints or suggestions on what else to look at? It's got me and my friends completely stumped.
