Posted on in Categories , , , , , , , , , , , , last updated August 13, 2009

I need Photoshop alternative under Ubuntu Linux for basic editing. I know Photoshop can be run using Wine but I’m not able to afford expensive software for just basic editing. Can you suggest a few free FOSS apps that works as alternatives to Photoshop under Ubuntu or Fedora Linux desktop operating systems?

I revived my new Dell server pre installed with Red Hat Enterprise Linux server v5.2. However, my box boot with a GUI login system ( Gnome ). There is no reason to run X Windows on my dedicated mail and Apache web server. I only need ssh. How do I disable X login and windows without reinstalling the operating system to improve security and performance?

Tunneling X Connection Through Intermediate Linux / BSD Gateway

Posted on in Categories , , , , , , , , , , , , , , last updated May 7, 2009

I‘ve ssh gateway behind my NAT firewall. So all users must first login to my gateway host from the internet and then login to other machines on the LAN. This works great for cli based apps. However, few users would like to run x apps from internal LAN hosts and tunnel X display through intermediate ssh gateway and display back output on their local system. For example, from localsystem user makes connection as follows:

ssh -X [email protected]
ssh -X [email protected]

X forwarding fails with an error:

Error: Can’t open display:

How do I fix this problem and allow users to use X apps with my intermediate Linux / BSD gateway?

Linux Gnome Numeric Keypad Disabled [ Mouse keys ]

Posted on in Categories , , , , , , , last updated December 28, 2008

Q. I’m using Gnome under Ubuntu Linux and my numeric keypad is disabled. Pressing numlock key does not work any more. I’m not able to use numbers or special symbols from numeric keypad. Reboot does not help or using different keyboard does not help. However, numlock only works if I switch to text console by pressing CTRL+ALT+F1. Now, I’m dam sure this is related to X.org or Gnome. How do I fix this problem?
