Posted this thread on the main Nvidia community forum and @jaafaman suggested I post over here for this kind of problem. I read the pinned post about running the nvidia-bug-report.sh, which I did after I tried to keystroke into a TTY and I scrolled through it, couldn’t understand it, but I don’t see a place to attach it to this post as there is on some forums??? It’s set up as a .gz file, but opening it is quite large, so I won’t paste it here at this time. Right now I’m in Leap 15.1–fn+Ctrl+alt+f2 goes to black screen and fn+ctrl+alt+f7 gets it back to GUI, but no TTY.
Awhile back I upgraded my '12 Mac Pro video card to a GTX 780 so that the machine could run 10.14 Mojave. I run a multi-boot machine with a number of OSX versions and a number of linux installs of various flavors. After that upgrade I started noticing that I couldn’t “revive” from suspend and posted my concerns on a debian based forum and they recommended switching from the “nouveau” drivers to proprietary nvidia drivers. On the two ubuntu based systems I have installed that is very easy through the GUI, but on the OpenSUSE and debian systems it takes some knowledge . . . but I got that done starting a few months back.
Recently I was trying to help a buddy get a linux install on his Mac and I was reading a thread on the Ubuntu Apple Hardware User sub-forum and I thought, “Hey, why don’t they log into a TTY to help solve their problem?” . . . so just to check it, I tried to log into a TTY on my '09 MBP that also has Nvidia graphics card in the Leap 15.1 partition I have on that computer . . . and making the usual keystrokes the screen went black . . . but, no TTY, no login prompt . . . nuttin but black. Possibly in that computer I might have been able to “exit” the black and back into the GUI. But, on some of my MP linux installs the keystrokes get me to black and then the computer shuts down?? Or, in some cases won’t return to the GUI . . . have to shut the computer down . . . and cold boot.
So, I became somewhat alarmed, all of the nvidia drivers were either added by the “additional drivers” or in OpenSUSE by adding Nvidia to the repos via Yast, selected from what was shown to be appropriate for the OS . . . . Meaning I didn’t “find” the drivers lying in a ditch, and then like clean the dirt off of them and then try to “extract” them and install the parts . . . . I posted my dilemma on the Lubuntu Users list serve, and a little while later a guy replied saying, “I booted a daily and checked it out and it’s working fine . . .” and he listed his computers and their hardware . . . took me a few hours to realize, “Hey, they are all radeon cards that he is using . . .”??? And then I thought back to the “suspend” issues after the Nvidia card, and that made me think, “Perhaps this is an Nvidia driver issue?” Ran a google on it, found a thread in the Linux Mint forum describing almost the same problems with the TTY and tracing it to Nvidia drivers, I think this LM thread was from 2016 . . . it gave a few mods to do to the /etc/default/grub file, I tried a couple of them . . . but it didn’t fix the issue. The thread suggests if that didn’t work, wait until Nvidia comes up with an update . . . ???
In my Siduction install I have from xinxi -v3 “driver: nvidia v: 430.40” keystrokes get me to a black screen and then back to GUI, but no TTY terminal shows up . . . kind of handy to be able to get to a TTY at times . . . is there a “fix” coming? Seems to be affecting, my ubuntu, OpenSUSE, debian system in two Macs with Nvidia cards . . . . Any thoughts or easy fixes??
