![]() To make life easier, so that the application is just ‘click and run’ for the purposes of what we need it to do some default settings should be changed (which then will obviously, not subsequently require resetting first time). It would be advisable that users pin gfxCardStatus to the dock to serve as a reminder to start the application upon reboot. This problem is however fairly minor compared to the consequences of not using it, so I’m sure we can live with temporarily. One thing that is key to note from our testing of v2.0 is that even with the ‘run at startup’ option enabled, gfxCardStatus doesn’t appear to actually start upon booting and therefore it is necessary to run the application explicitly by double clicking it in the Applications folder (or an alternative location where you have copied it to, if not to Applications). ![]() The developer has put this down to the updated gfxCardStatus ‘triggering’ a defect related to the nVidia graphics card which in turn triggers the OS X BSOD. Tests show that after multiple reboots the “Integrated only” option continues to work with each reboot, unlike the experience we had with gfxCardStatus v2.2.1 in testing. On this for more details see this discussion.Results from our initial thorough testing of gfxCardStatus version 2 in response the OS X BSOD ‘superbug’ are very promising which means that we now have a fully working and documented solution which has been documented previously.Īlthough not ideal this will no doubt come as a relief to many MacBook Pro mid-2010 model owners who are currently experiencing the disabling OS X BSOD bug. If it doesn't find it automatically, you can use the legacy ATI driver (cat 9.3) found here. The ATI proprietary driver should appear, enable it, and then restart X. Go to System->Administration->Hardware Drivers, and search for new drivers. To install ATI's proprietary driver, as it is not installed by default due to licensing issues. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash reboot=pci acpi_backlight=vendor" Nearly there, we just need to change some boot parameters now: Option "RegistryDwords" "EnableBrightnessControl=1" Sudo gedit /etc/pm/config.d/macbookair_fixĪDD_PARAMETERS="-quirk-reset-brightness"įind the Device Section for the Nvidia driver and add this line to the end of the section: Option "RegistryDwords" "EnableBrightnessControl=1" To fix backlight and touchpad issues with suspending, create a new file: usr/bin/nvidia-settings -a /DitheringDepth=1 So we need to enable dithering at 6 bits per colour channel to smooth colour gradients.Īssuming you use gdm (the default) as login manager, run:Īdd to the end of the file, but above the exit 0 line: Note: this script broke my fresh installation so not sure it s a good idea to use it.Īpple uses 6-bit LCDs which support only 262144 colours instead of 16 million. Try this ubuntu documentation steps to set up the graphic card however the steps are for Nvidia but I think you can try them with ATI too. ![]()
