This bug was fixed in the package ubuntu-drivers-common - 1:0.2.91.6 --- ubuntu-drivers-common (1:0.2.91.6) trusty-proposed; urgency=medium * UbuntuDrivers/detect.py, debian/tests/system, tests/ubuntu_drivers.py: - Do not autoinstall the broadcom driver. The open driver should be a better solution now (LP: #1306928), as the binary driver prevents a number of systems from using the wireless card. - Autoinstall linux-firmware-nonfree. This will help now that we no longer autoinstall Broadcom's binary driver. - Fix the relevant tests now that linux-firmware-nonfree has replaced bcmwl. * gpu-manager.c, tests/gpu-manager.py: - Ignore CRT displays when using PRIME. This works around systems whose BIOS provides a ghost output (LP: #1296020). - Check that we don't remove xorg.confs on 1st boot (as per the previous SRU). - Try harder when loading bbswitch (LP: #1310023). If loading bbswitch fails try with or without the skip_optimus_dsm=1 option. Also, make sure that we trim dmi resources or matching will give us false positives. - Switch to intel/SNA for optimus systems (LP: #1326257). - Make sure to unload nvidia-uvm or nvidia won't be unloaded. - Make sure to walk properly the /dev/dri dir. This prevents the program from stopping when, for example /dev/dri/card1 is available while /dev/dri/card0 is not. -- Alberto Milone alberto.mil...@canonical.com Fri, 06 Jun 2014 11:20:28 +0200 ** Changed in: ubuntu-drivers-common (Ubuntu Trusty) Status: Fix Committed = Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1326257 Title: [nvidia-prime] Cannot adjust brightness in guest session and results in black screen while changing the resolution To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1326257/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
