If my monitor is optimized for 1280 x 1024 resolution @ 60 Hz, what should I choose for V freq and H freq…?

How do I get Ubuntu to work with my KVM switch properly?

Posted on July 18, 2010 by admin| 1 Comment

I recently installed a Belkin Omni-Cube F1D092 KVM switch so that I could use both my Windows 7 computer and my Ubuntu Linux computer using the same Keyboard, Mouse, and Monitor. Upon installing the KVM switch Ubuntu stopped detecting my monitor and throws me at a command prompt.

The actual error says something along the lines of:
Screens Found, but no working modes detected.

I have searched Google and the Ubuntu forums for the answer and have yet to find one. I am currently using a Back Track 3 live cd with the computer (so that it is not a wasted hunk of metal) and when I use the Back Track 3 cd X loads up fine.

So does anyone know what it is that makes Back Track 3 manage to load X when Ubuntu can’t? And if so how to transfer that over to make Ubuntu correctly load X? Or even how to fix the problem in Ubuntu so that X will run again.

My computer:
Running Xubuntu 9.10
Using Belkin Omni-Cube F1D092
Using Generic Monitor (Supporting Resolution of 1280×1024)
Computer is a Compaq Presario PC Model SR5030NX
I am sure that the KVM switch will work with Linux, because it works fine when I am using my Back Track 3 Live CD distro of Linux.

Old Pentium 2 Monitor Black (Video Card Problem)?

Posted on July 11, 2010 by admin| 4 Comments

I work as a part-time computer technician assistant for allinonecomputer and I had a customer bring her computer to my house, and due to me being limited in parts, I tested her Power Supply on my brother’s motherboard, turns out the power supply was bad because it fried two motherboards.

So I had to replace his HP intel motherboard with his celeron 2.7ghz processor with a pentium 2 266mhz processor. Problem is… the damn thing boots up, but the monitor remains black. It has one agp slot and about five pci slots, and one ISA slot.

I have four 4-16mb video cards I tried using in every single slot, repeatedly booting it up and shutting it down and switching. But every slot and card I try… nothing works.

I tried booting a linux live CD, but for some reason (that I can’t see) it’s not booting at all. I also tried a windows CD, but I couldn’t see what was going on.

Any suggestions?

(I’ve gotten most of my computer experience from modifying programs and frankensteining computers in my basement, so I have a lot of non-professional computer background. )
