Hello,
tries to find a way to underclock the gpu of an HP elitebook 8460p
with a radeon HD 6470M, because it does not handle well the 3d
requirements of a current plasma desktop and leads to the laptop
turning just off. (Turning off the compositor as a workaround.)
So "rovclock -i" leads on that system to the same exception.
This is just for the record as there might not be any
update for this package.
Kind regards,
Bernhard
