Request for HP laptop and desktop owners

[67GTA]

If you have a HP laptop or PC with Vista pre-installed, please do the following:

After a normal boot run

Code: Select all

dmesg

in a terminal and save it as dmesg1. Then boot again and add this to your boot options

Code: Select all

acpi_osi="Linux"

Then run dmesg again and save it as dmesg2. Please compare any differences between the files and post them here. An easy way to compare is to use

Code: Select all

diff

in a terminal.

Code: Select all

diff <path_to_dmesg1> <path_to_dmesg2>

Also check the output before and after of these commands to see if anything changes:

Code: Select all

cat /proc/acpi/thermal_zone/THRM/trip_points

Code: Select all

cat /proc/acpi/thermal_zone/THRM/temperature

Code: Select all

cat /proc/acpi/fan/FAN/state

It seems that HP codes the DSDT to detect Vista, VistaSP1, VistaSP2, etc & Linux and treats them differently when detected. This is coded automatically in Vista, but for Linux, the acpi_osi="Linux" option has to be added to the boot options. By adding this to my HP laptop and desktop with Opensuse, acpi thermal is populated where it wasn't before. I'm curious to see if it has the same effects in Mint.
