Update - if I suspend/resume AFTER modifying /proc/.../LCD/brightness
directly, the display brightness is not dimmed after resume.
HOWEVER, if I unplug AC power and then plug back in, the brightness
reverts to the dimmed value.
For example, this is after resume (with a previously modified
/proc/.../brightness):
<PROMPT>$ cat /proc/acpi/video/VGA/LCD/brightness
levels: 20 24 29 36 44 53 63 76 100
current: 100
AC adapter unplugged:
<PROMPT>$ cat /proc/acpi/video/VGA/LCD/brightness
levels: 20 24 29 36 44 53 63 76 100
current: 29
AC adapter plugged in:
<PROMPT>$ cat /proc/acpi/video/VGA/LCD/brightness
levels: 20 24 29 36 44 53 63 76 100
current: 44
