I'm running RH6.0 w/2.2.10, tested both with and without rtc compiled in.
All on a Thinkpad 755c notebook.
Console-based realtime programs (top, etc) update correctly and reliably,
and seem to work great.
However, in XFree86, programs such as gpppkill and gstripchart run for a
couple of seconds and/or update iterations, then simply stop. If I move the
mouse over their windows and right-click a context menu or something, they
will tend to update their displays once in response to the mouse event, but
then become idle again.
The behaviour is consistent with them no longer receiving timer-based events
(their code has generic event handlers that respond to mouse and timer
events and update via either, so it's understandable that the mouse event
would trigger an update).
I've also had related issues, such as the screen blanking/screensaver
initializing every couple of seconds, only held at bay with continuous mouse
movement (finally had to turn off blanking/saving altogether), and focus
switching windows extremely slowly (like 30 seconds or so) on an unloaded
Any ideas? Right now my X windows environment is pretty screwed up without
reliable timer events...
