Nomodeset : Proxmox and Ubuntu

At times where the connected Monitor or Graphics card are unable to support certain resolution, either the wordings is too small to read or overly large making some info or buttons unable to be seen.

A simple fix is to "edit" the grub boot file and this can be done on-the-fly easily.

1. During the boot-up, select the appropriate install option and Press [E] to edit the boot-up configuration.

2. Append the "nomodeset" word at the end of the following line.

for Proxmox :-

linux     /boot/linux26 ro randisk_size=16777216 rw quiet splash=silent proxtui vga=788 nomodeset

for Ubuntu :-

GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"

3. Proceed to save and exit the configuration file, Press [CTRL] + [X].

If you want the changes to be permanent after installation completed, you will need to modify "GRUB" file with the same option.

4. Edit the "GRUB" configuration file.

sudo nano /etc/default/grub

5. Append the "nomodeset" as per above steps.

6. Update the "GRUB" configuration.

sudo update-grub

7. Finally reboot the server for the new configurations to take effects.

Command : Rename Multiple Files via Batch Script

Rename multiple files via batch script. Some times you need to rename multiple files and instead of renaming each file individually or relying on some 3rd party apps, you can now just use a simple batch script to achieve the same results.

Windows : Microsoft Edge Browser with Script

Sometimes we just need to create a shortcut that run Microsoft Edge browser to a specific URL or Website. This could be achieved easily if your "Default" browser is configured to Microsoft Edge, but what if your computer have 2 or more browsers like Google Chrome ?

This is especially true if the "Default" browser is configured to Google Chrome and that specific URL or Website only works with Microsoft Edge.

Thus by simply creating a shortcut to open that specific URL will only opens up Google Chrome instead of Microsoft Edge which is a bummer.

Let's get started :-

1. First you will need to create .vbs file with the following code.

Set Edge = CreateObject("WScript.Shell") Edge.Run "msedge.exe https://demo.com"

* Replaced https://demo.com with your specific URL.

2. Save the above file as "edge.vbs", you can of course name it whatever filename you want.

3. Then create the shortcut to that "edge.vbs" on your desktop or any location you preferred.

4. If you want Microsoft Edge to open up with "Maximized" screen, just add the following line into .vbs file.

Set Edge = CreateObject("WScript.Shell") Edge.Run "msedge.exe https://demo.com", 3, false

Now Microsoft Edge will open that specific website in maximized screen.
