I can also confirm that the nvidia-340 package in 20.04 builds usable kernel modules and works fine on the same 2008 MacPro with Mac rom'd GTX680.

For example, on my MacPro 3,1 equipped with an EVGA GTX-680 Mac version graphic card, the nvidia 360, 390 and 396 drivers all fail due to issues with the new nvidia_drm module resulting in no video output on DVI and HDMI. https://devtalk.nvidia.com/default/topic/1042691/linux/black-screen- with-mac-version-of-gtx-680/1 Similiar issues exist for a number of PC users as well... https://devtalk.nvidia.com/default/topic/1037997/xid-61-black-screen- on-startup-ubuntu-18-04-gtx-1060-mobile/ of which only some have been resolved. The nvidia-340 drivers are the recommended fall back according to the Nvidia linux developers. Unfortunately, the installation of the current nvidia-340 340.107-0ubuntu2 packaging is in really bad shape. The first error one sees while attempting to install it are dpkg-divert errors like those described in https://askubuntu.com/questions/419304/dpkg-divert-error- rename-involves-overwriting-usr-lib-xorg-protocol-txt-wit but for the files... /usr/lib/x86_64-linux-gnu/libEGL.so.1.distrib /usr/lib/x86_64-linux-gnu/libGLESv1_CM.so.1.distrib /usr/lib/x86_64-linux-gnu/libGLESv2.so.2.distrib. /usr/lib/x86_64-linux-gnu/libGL.so.1.distrib Currently one has to manually move these aside under a .bak suffix to get past these post-removal script errors. I believe these issues may be already addressed in the current nvidia-340 packaging residing on the ppa:graphics-drivers/ppa repo. The second installation issue that occurs is the same as that described in https://askubuntu.com/questions/969352/uninstalling-and- then-reinstalling-nvidia-384-kills-colord where currently the fix is the same. One has to edit the installed nvidia-340.postinst file and change NEWEST_KERNEL=$(get_newest_kernel "$(KERNEL") to NEWEST_KERNEL=$(get_newest_kernel "$CURRENT_KERNEL") following executing sudo dpkg-reconfigure nvidia-340 to allow the installation to cleanly complete. Lastly, there seems to be a missing dependency on the nvidia-340-dev that prevents akmods from building the kernel modules which should be fixed. The nvidia-340 drivers are supported until the end of 2019 by which time hopefully Nvidia will finally clean up their current issues with the newer drivers on problematic hardware. https://nvidia.custhelp.com/app/answers/detail/a_id/3142 ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: nvidia-340 340.107-0ubuntu2 ProcVersionSignature: Ubuntu 4.18.0-10.11-generic 4.18.12 Uname: Linux 4.18.0-10-generic x86_64 NonfreeKernelModules: wl nvidia ApportVersion: 2.20.10-0ubuntu13 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Sun Oct 14 12:41:21 2018 InstallationDate: Installed on 2018-04-26 (170 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180425.1) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: nvidia-graphics-drivers-340 UpgradeStatus: Upgraded to cosmic on 2018-09-30 (14 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/+bug/1797791/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
