Thanks for the suggestions. I tried both, but they did not help. Here is
what I have:
> xset q
auto repeat: on key click percent: 0 LED mask: 00000002
00: Caps Lock: off 01: Num Lock: on 02: Scroll Lock: off
03: Shift Lock: off 04: Group 2: off 05: Mouse Keys: off
auto repeat delay: 500 repeat rate: 20
auto repeating keys: 00feffffdffffbbf
bell percent: 50 bell pitch: 400 bell duration: 100
acceleration: 2/1 threshold: 4
prefer blanking: yes allow exposures: yes
timeout: 0 cycle: 600
default colormap: 0x20 BlackPixel: 0x0 WhitePixel: 0xffffff
DPMS (Energy Star):
Standby: 600 Suspend: 600 Off: 600
DPMS is Disabled
Server does not have the FontCache Extension
