The service unit file # Service unit file to try early GPU detectionĭescription=Trying to detect nvidia GPU earlier The gpu-detect.sh script: #!/usr/bin/bash I THINK I managed to create a small unit with this article įor the moment, it only displays a message during the startup process, but… it’s here If I type “sudo service lightdm restart”, I can log in into lightdm, X starts and this time, I’m in nvidia performance mode, as expected… If I disconnect, I’m back at the terminal. No optimus applet, minimal nvidia-settings, and “inxi -G” says I’m using the AMD GPU… When in prime “nvidia performance” mode (and only in this mode), when I launch “sudo nvidia-bug-report.sh” from the terminal, during the report generation, SOMETHING happens that automatically launches lightdm, the login screen appears, and X starts normally if I log in.īUT… on closer inspection, it’s as if I was in "Intel"mode. On a side note, a funny thing I forgot to mention : I tried disabling it, startup takes a little bit longer, but it didn’t fix the black screen problem. The only thing I found that could “slow down” startup is the Fastboot option, which was enabled. I can enable or disable various devices (Wireless, LAN, audio… but not GPU), prevent the use of some external USB devices, disable secure boot (was already disabled to install Mint), flash a new bios, enable or diable SVM and change boot order. Its quite fancy compared to the old bioses I’m used to, with nice shiny graphics, but a very limited number of options, even in advanced mode… :( The latest available bios for my laptop (FA706IHRB) is version 304 from 3. X is displayed for less than a second, and the Mint startup sound begins playing, before the screen goes pitch black and the sound get cut before the end… game over :(Īny idea on how to fix this annoying login problem ? Thanks !.The system starts and the recovery menu appears.In grub, I choose to start in recovery mode.“glxinfo | grep vendor” says nvidia GPU is used.nvidia-settings works with all options (antialiasing, etc…).the optimus applet shows the NVIDIA logo, indicating I’m in “nvidia” performance mode.I will try to include the log for this configuration in another message (forum restrictions…) perfs get higher when using the nvidia card, as it should.“_NV_PRIME_RENDER_OFFLOAD=1 _GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo | grep vendor” says NVIDIA GPU is used. “glxinfo | grep vendor” says AMD GPU is used.nvidia-settings works with more options (profiles and stuff…).the optimus applet shows the AMD logo, indicating I’m in “on-demand” mode.Lightdm login screen is displayed as expected.I log in, then I enter “sudo service lightdm restart”.The screen goes pitch black before login… : (.If I switch to “prime-select on-demand”:.nvidia-settings works, but with minimal options (quite logical, as the Nvidia driver is installed but not used).If you have any questions, please post them in the comment section below.On my ASUS TUF 706 (Ryzen 5 4600H with AMD iGPU + Nvidia GTX 1650 eGPU), I installed Linux Mint 21 (Kernel 5.15.0-46) and the Nvidia drivers (515.65.01)Īfter MANY failures and retries, I managed to get a “kinda” working setup : I expect that the process was straightforward. In this article, you’ve learned how to set up an SSH Passwordless login using an ssh key. Step 4: Test SSH Passwordless Login from 192.168.0.12įrom now onwards you can log into 192.168.0.11 as a sheena user from server 192.168.0.12 as a tecmint user without a password. Save the file and restart the SSH service. To do this, open the SSH server configuration file on the remote server: $ sudo nano /etc/ssh/sshd_configįind the line containing PasswordAuthentication and set it to no. Step 3: Disable Password Authentication (Optional)įor increased security, you can disable password authentication on the remote server and only allow SSH key authentication. $ ssh "chmod 700 ~/.ssh & chmod 600 ~/.ssh/authorized_keys" Make sure that the correct permissions are set on the ~/.ssh directory and the ~/.ssh/authorized_keys file on the remote server. ssh directory as a file name authorized_keys. Use SSH from server 192.168.0.12 and upload a newly generated public key ( id_rsa.pub) on server 192.168.0.11 under sheena‘s. Your identification has been saved in /home/tecmint/.ssh/id_rsa. $ ssh-keygen -t rsaĮnter file in which to save the key (/home/tecmint/.ssh/id_rsa): Įnter passphrase (empty for no passphrase): Įnter same passphrase again: Step 1: Create Authentication SSH-Keygen Keys on – (192.168.0.12)įirst login into server 192.168.0.12 with user tecmint and generate a pair of public keys using the following command. In this example, we will set up SSH password-less automatic login from server 192.168.0.12 as user tecmint to 192.168.0.11 with user sheena.
