https://bugzilla.rpmfusion.org/show_bug.cgi?id=3240 Bug #: 3240 Summary: bbswitch-kmod Classification: Unclassified Product: Package Reviews Version: Current Platform: All OS/Version: GNU/Linux Status: NEW Severity: normal Priority: P5 Component: Review Request AssignedTo: rpmfusion-package-review(a)rpmfusion.org ReportedBy: leigh123linux(a)gmail.com CC: rpmfusion-package-review(a)rpmfusion.org SPEC: http://leigh123linux.fedorapeople.org/pub/review/bbswitch/1/bbswitch-kmod... SRPM: http://leigh123linux.fedorapeople.org/pub/review/bbswitch/1/bbswitch-kmod... Suitable for rpmfusion-free. bbswitch is a kernel module which automatically detects the required ACPI calls for two kinds of Optimus laptops. It has been verified to work with "real" Optimus and "legacy" Optimus laptops (at least, that is how I call them). The machines on which these tests has performed are: Clevo B7130 - GT 425M ("real" Optimus, Lekensteyns laptop) Dell Vostro 3500 - GT 310M ("legacy" Optimus, Samsagax' laptop) (note: there is no need to add more supported laptops here as the universal calls should work for every laptop model supporting either Optimus calls) It's preferred over manually hacking with the acpi_call module because it can detect the correct handle preceding _DSM and has some built-in safeguards: You're not allowed to disable a card if a driver (nouveau, nvidia) is loaded. Before suspend, the card is automatically enabled. When resuming, it's disabled again if that was the case before suspending. Hibernation should work, but it not tested. Precautionary measure : On some machines, turning off the card is permanent and the card does not reappear on subsequents reboots, which can result into the screen staying black all the time, including the BIOS screen. If it occurs, first try to shutdown, unplug power cord, remove battery, wait 30s, then put everything back in and boot. If it's not solved, then the solution is to reset the BIOS to factory settings. Before executing bbswitch for the first time, it is therefore recommended to take note of the full key sequence in the BIOS to do a reset. https://github.com/Bumblebee-Project/bbswitch -- Configure bugmail: https://bugzilla.rpmfusion.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
