I found the calls in the acpidump and could see on beforehand that it does
not work for
you since these kind of calls require additional treatment, namely saving
and restoring
the PCI configuration space.
Please confirm (with PM disabled, but keep cardo{n,ff} scripts) that the
following sequence
does work (after making sure that you no acpi calls have been performed
this session, i.e.
by rebooting)
# should not show FF FF FF ...
xxd -c4 /proc/bus/pci/01/00.0
cat /proc/bus/pci/01/00.0 > saved.txt
sudo tee /proc/acpi/call < /etc/bumblebee/cardoff
# should show FF FF FF ...
xxd -c4 /proc/bus/pci/01/00.0
sudo tee /proc/acpi/call < /etc/bumblebee/cardon
# should not show FF FF FF ...
xxd -c4 /proc/bus/pci/01/00.0
sudo tee /proc/bus/pci/01/00.0 < saved.txt
optirun glxgears
Please attach the output of the above commands.
Regards,
Lekensteyn
