Hello. I have installed bumblebee. Bumblebee works fine to optirun softwares on my computer. However, I find that bumblebee cannot disable my discrete card when I don't use them. I find that bbswitch doesn't work well because ls: cannot access '/proc/acpi/bbswitch': No such file or directory and modprobe: ERROR: could not insert 'bbswitch': No such device. Any help will be appreciated. Thanks.

Hello. I have installed bumblebee. Bumblebee works fine to
optirunsoftwares on my computer. However, I find that bumblebee cannot disable my discrete card when I don't use them. I find that bbswitch doesn't work well becausels: cannot access '/proc/acpi/bbswitch': No such file or directoryandmodprobe: ERROR: could not insert 'bbswitch': No such device. Any help will be appreciated. Thanks.
