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.
