I have an older Asus Eee PC that in previous versions of Lubuntu I was able to install and use acpi-call-dkms to disable my NVidia graphics card and enable the Intel graphics for the next boot.

I installed a fresh copy of Lubuntu:

Distributor ID: Ubuntu
Description:    Ubuntu 19.04
Release:        19.04
Codename:       disco

I then installed acpi-call-dkms:

acpi-call-dkms is already the newest version (1.1.0-4).

When I make my call which worked in previous versions of Lubuntu (16.04):

eee:~$ sudo echo "\OSGS 0x01" > /proc/acpi/call

I get this:

bash: /proc/acpi/call: No such file or directory

I have searched around and even checked my own notes from when I upgraded to 16.04 in the past, but can't make it work this time...

Any help would be greatly appreciated.

Thanks, Bob
