Very Old CRT monitor

Postby Microman171 » Sun Nov 09, 2008 5:21 am

Hey Mint users,

I am new to the whole Linux scene and have decided to use Mint as my first distro.

Currently I am having trouble with my monitor. I have a 640x480 monitor made by commodore. It is many years old. When I try to boot Mint from the CD, the monitor is all distorted and I cannot make out *anything*. The mouse (i know its the mouse as it moves) it a 30mm right to left diagonal oval. It is about 5mm at the widest part. I have no Idea how to change the resolution in the boot. I have looked around and have found this code VGA=765. I know where to enter it but I get the error, unknown (code?) 30(2?).

Does anybody know how I can boot into mint so I can install and change my preferences to set the resolution to be 640x480? I have changed the setting in windows 2000 and they work fine.

Thanks,

Microman171

Your monitor gets completely out of range and that's why it's garbled
Out of range = the signal from the video card is outside the specs of the monitor
I suppose you have a very old video card too
My recommendation is to get a new monitor, you only have one set of eyes
The only way to fix it that I can think of is to use compatibility mode
I would use vga=769 if necessary (not VGA is not the same as vga)

Don't fix it if it ain't broken, don't break it if you can't fix it

I tried the compatability mode with no luck. I also tried 'vga=769'. Neither seemed to make any difference.

I need to somehow boot into 640x480. I know this works because it works for windows 2000 that I have currently installed.

Before I give up, I am going to install the linux useing a different monitor (temporary) and then change the settings. If I swap it over AFTER changing it, it should work, correct?

Thanks for your help Husse

It could work
However to use 640x480 on a 17 inch monitor seems like madness to me

Temporary. I will use it so I can see.

Linux mint's live CD boots in too high a resolution, but if I use a good monitor and then swap it, I should be able to see.

I tried it last night and it seems Linux Mint GNOME is a little to high end for this computer (256mb ram, 866Mhz CPU). It was very laggy. So I decided to download the fluxbox edition. I shall try that after school.

Thanks :D
