Unfortunately, I think the 340xx series driver is being deprecated.
You can read these threads here:
Also, if you look in the branch compare and search for nvidia-340, you can see that it’s already removed from unstable and testing branches. So I assume it will be removed from the stable branch very soon.
So I would recommend bumblebee driver instead of the proprietary driver.
Hey, i have the same problem. ASUS laptop Geforce GT540M (Fermi).
CleanInstalled Manjaro with open drivers, installed 390xx Nvidia via the MSM, Switched to Kernel 5.40, followed the tutorial for KDE, but now after reboot theres only a Black Screen with the Cursor visable. Is there any other way to get the dGpu going, i tried Bumblebee drivers with optimus-manager and qt but again there would only be black screen.
Did you uninstall the open drivers ??? This is important!
First install the nvidia-390xx-utils, linux54-nvidia-390xx, mhwd-nvidia-390xx(MHWD module-ids for nvidia) and for good measure lib32-nvidia-390xx-utils. I have all of these but the 340xx version.
Did you read the Step 5 where it says
e.g. KDE edition
Create a new file,
and make it executable.
Do you have SDDM as login manager ?? Maybe you missed this step or something, double check every step. If the login manager is not configured properly, you could have black screen simply because the manager is not using the dGPU and doesn’t know how to display the login screen.
For other results and explanations try googling how to use dedicated graphics card instead of integrated manjaro linux it will show couple results from this forum and other stuff.
Fresh Install, deinstalled open drivers, sudo pacman -s all 390xx drivers followed the Tutorial, setup executable for my SDDM, reboot and after the Login screen i see for 2 seconds my desktop after that it turns black, still can open programs with hotkeys.
Alt Space to open searchbar, opened Resolution and i can see that in Display Configuration are 2 devices listed, LaptopScreen (Primary) and VGA-0.
Dont know if thats important.
sorry for spamming, but i checked the Hardware Configuration and it still showed (after the reboot)none of the drivers installed, so clicked on install video-nvidia-390xx wich seems to have worked.
inxi -G returns
Seems like your hardware will be unsupported really soon. You could install Nvidia drivers (Bumblebee or not) but in a coming update probably early next year on end of the month if I guess, they will get removed. I don’t have the ETA but it seems very soon, it is already dropped in Testing branch since a month.
Yeah you can also compile your own Kernel and add your own patches, but do you think the user here will be able to maintain a custom Manjaro installation on his own, when he’s not even sure how to install video drivers from the official easy GUI?
Yes It is possible, by downgradin xorg (which then will create other issues regarding packages depending on xorg), having older LTS kernel, to install foreign DKMS packages from AUR or other methods, sure, but officially, Manjaro drop support for Nvidia 340.
No, I don’t think so, but if you want to drive a McLaren, you at least have to know how to drive and have the will to improve
And there is the community to help you with that.
Xorg 1.20.10 is still working nice with 340.xx(official repo) , so far there is no problem on my end. I will cross that bridge when I come to it So unless something really bad happens, like some security hole in the driver, am stying on it.
