[ltp] Re: Strange LCD issue

[Petr Praus]

cat /proc/acpi/thermal_zone/THM0/temperature

This should show you something like this:
temperature:             48 C
(in my case)

or you could try:
cat /proc/acpi/ibm/thermal
Output should look like this:
temperatures:   48 38 32 53 20 -128 21 -128 34 40 39 -128 -128 -128 -128 -128

First number is your CPU temperature. It may be possible some number
in that list is your GPU temperature, but I'm not really sure of that
nor I don't know which one it could be.
