Monitor flaking out
Recently (the last week or so), my Sony Multiscan 15sf monitor
has started to act funny. After its been on for a few minutes,
the picture starts to flicker a bit, and then after a few more
minutes, it goes completely black.
This is not the normal DPMS-like behavior: it "flashes" brightly
for a split second, goes dark, and then both the "On" and "Power
Saving" LEDs on the front panel flash repeatedly. If I press the
power button, it turns back on. This is not related to
screensaver activity--it happens while typing and moving the
mouse, and it will not turn back on until I hit the power button.
This started happening just a few days ago. I've been running
Debian 2.1 and XFree86 for a few months without problems. But I
have recently upgraded to a 2.2.11 kernel, and I've upgraded
several packages to unstable (primarily gcc- and libc6-related
I suspect that this old monitor is just reaching the end of its
lifetime. But if anyone knows why a 2.2.x kernel or any of the
unstable packages might be causing problems, please let me know.
