Installing Nvidia Drivers on Ubuntu - The Easy Way

Fri, 11 Jul 2025 20:20:31 +0000

I had installed Nvidia Drivers on my Desktop using ubuntu-drivers --autoinstall thinking that everything should work properly. But turns out I was wrong. It had weird issues, and I was not able to use the Nvidia Encoder in OBS either. So, this is what I had to do to get everything fixed.

Step 1 - Remove any old drivers

Step 1.1 If they were installed through the PPA

That is, if you installed the drivers using apt

Linux : NFS not mounting on boot even with fstab entry

Wed, 17 Jul 2024 13:30:53 +0000

If you have come across a problem where you had an entry for an NFS server on any systemd system, and it is not mounting those at boot, but it mounts when issuing a sudo mount -a I have a solution for you

The Fix

Update your fstab entry by editing /etc/fstab and adding these options.

server IP:/share_path   /mountpoint/on/client  nfs  _netdev,noauto,x-systemd.automount,x-systemd.mount-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

A practical example

192.168.40.100:/volume1/Media     /nas/media   nfs  _netdev,noauto,x-systemd.automount,x-systemd.mount-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

This should be it

How to install sudo on Windows 11

Fri, 23 Feb 2024 13:29:14 +0000

This post is from February 2024; sudo is no longer limited to Insider Preview. It is available in Windows 11 version 24H2 and later, so the availability advice below is outdated.

So, if you do not want to go through the hassle of getting insider preview builds, just wait a little bit longer.

ChatGPT: How to switch back to GPT-4 in a conversation

Sat, 20 May 2023 22:39:22 +0000

Update : 18 June 2023
This method no longer works. Looks like OpenAPI returns a 403 error when trying this method

The Problem

Imagine a situation where you're engaged in a captivating conversation with GPT-4 via ChatGPT, maybe it's assisting you with troubleshooting a problem, or you're working on a college assignment - essentially any context. There is a limit to the usage of GPT-4 (25 messages in a span of 3 hours as per the current policy). When this limit is exceeded, the system transitions to GPT-3.5. The challenge arises because there is no mechanism available to revert back to GPT-4, even long after your quota has been refreshed.

How to send commands to nested tmux sessions

Wed, 03 May 2023 20:17:27 +0000

TL;DR : Press the prefix key twice

In this short blog post, we'll explore how to send tmux commands to a remote session while working within a local tmux session using the same prefix key.

That is, you have a local tmux session, you have connected to a remote host via ssh within this tmux session and now you have opened a new tmux session within that.

This scenario creates a "nested" tmux session. To send commands to the remote tmux session without changing the prefix key, you simply need to press the prefix key twice.

The Error

If you are seeing the following error when trying to install NodeJS, I have an easy solution for you. This is the error

Not able to access hosts over SSH : no matching host key type found

Tue, 25 Apr 2023 17:05:45 +0000

This post is from April 2023; its Host * example re-enables legacy SHA-1 SSH signatures for every SSH host. Avoid applying it globally; if necessary, limit the exception to a specific trusted host.

This happens because in newer versions of the OpenSSH client the ssh-rsa key exchange algorithm (specifically the SHA1 signature - more info here) is no longer trusted by default.

If you are using anything newer than OpenSSH_8.8p1, OpenSSL 1.1.1l 24 Aug 2021 and are facing the following error while trying to ssh

Persisting SSH Keys (ssh-agent) across terminals (Windows and Linux)

Fri, 03 Mar 2023 17:09:22 +0000

The easiest way to persist ssh keys across different terminal sessions is to use the keychain tool.

Install keychain

Depending on your operating system, the command will vary

Ubuntu and Debian Derivatives

sudo apt update
sudo apt install keychain

Fedora

sudo dnf install keychain

Arch Linux

sudo pacman -S keychain

Configure Keychain to persist ssh agent

Open _{/.zshrc or}/.bashrc depending on your shell, and add the following entry to it

eval `keychain --eval --agents ssh id_rsa id_rsa_1`

Here, I am adding two keys id_rsa and id_rsa_1.
