If you see the earlier version listed, you can request the downgrade with this command: sudo apt-get install cinnamon-desktop= It should show you a list of versions available. As I have not a running installation I cannot test but the procedure should be similar to: sudo apt-cache showpkg cinnamon-desktop On Mint to downgrade a package you need to use apt-get on the command prompt. Option 2) The workaround useful for at least one of the users was to downgrade from cinnamon-desktop package version 4.6.2-2 (stock) to 4.4.1-2, until the issue is fixed. Option 1) It seems there is already out version 4.6.3 that should have fixed some bugs concerning multi monitors. Ideally Nvidia-driver-418 should do the trick. I am not using Mint, but I saw some complains concerning very similar problems on Mint Support Forum.īefore trying any potential solution below, I advise you to choose the driver you want to use and stick with it until the end of all your tentatives. So in conclusion, I can get the best results with the 390 driver, getting an independent laptop and monitor, but even with it I can't get the second monitor to work. There's no way to ever use this tool to configure things. Meanwhile when I try to use the graphical Nvidia settings tool, it either shows up completely empty, or with just a PRIME profiles tab, depending on which drivers I use. I've also tried wiping my nf, and generating a new one using nvidia-settings -r and that X-Windows command: none of them seem to help. It seems to have no effect: even when I use prime-select intel I still can't use the second monitor (the one presumably controlled by the Intel card). I've also tried using both bumlbebee and nvidia-prime (and even both at the same time, although apparently that isn't even supposed to work). I -uninstalled the manual installation, and I'm doing apt-get purge *nvidia* in-between each. I've also tried other versions without luck. this worked, but I couldn't run nvidia-settings, and it seems even the Nvidia people discourage installing this way now.installing the Nvidia drivers (418) from NVidia directly.
installing nvidia-driver-418 (recommended by Nvidia).works and I can see the second monitor in "Displays".However, now that I've installed Linux Mint 20, only one monitor (and the laptop display) works. Previously I was able to run both monitors from the laptop just fine. The laptop has an Nvidia GTX870M graphics card, which is a sort of combination card that works in tandem with the on-board Intel graphics card. Let me start by saying that on Linux Mint 18 I had this exact same hardware: same laptop, and same two monitors plugged into it.
