Since the update of DPMS to support amd64 on March 2, it has broken
rather badly on my ThinkPad T43 laptop. The problem showed up on
8-stable built on March 3 and is still present after an update to stable
of March 17.
When in vty text mode, after the idle normal delay, the display blanks,
but the backlight remains on, so the P in DPMS seems to be less than
effective. At that point, the non-graphics display is dead. It never
comes back when characters are entered. I can't get the display to come
back without a reboot.
I can, however, start X (and Gnome) and everything is fine. But
switching back to any vty results in a blank screen.
Any idea what happened and if there is a fix or workaround? Any data I
can collect?
The system is a uniprocessor Pentium-M:
