Hi!

Ok, I have a NEC Multisync 70 monitor and my video card is a Voodoo3.
When I boot in win98, the screen is ok. (I use 1024 x 768, 24 bits
resolution).

Now, if I boot in linux, (RedHat 6.1 with KDE 1.1.2)  then the screen
is shaking a bit. And it is more apparent on the edges of the desktop.
At the end, it becomes really annoying to see this shake....
(As with win98, the resolution is the same, 1024 x 768)

Is there a solution for that?

Thank you for your help!
Eric.

Hello!

I had a similar problem.

I had a high-intensity lamp positionned to the side of my monitor. I had
wanted to position it so I could see documents but not so as to glare
onto the screen.  When I moved the lamp, the jiggling screen problem
went away.

You might want to consider whether there is something in your
environment that might cause the same effect.

All the best!

Paul

You need to setup the XFree86 or whatever RH packages to setup the display.

The clue is that it works with Windows. It's not a lamp or a failing power
supply on the monitor, but it could become a failing power supply.

It's all about the frequentie in which the screen gets updated.

At a frequentie of 60, you will see the screen flickering en shaking.

You have to check the manual for the right frequenties (vertical en
horizontal) en change that directly in '/etc/X11/XF86Config' or use you
favorite X-configuration tool (choose then for 'user define', and give the
right frequenties.)

BTW: You can also find the right (optimal) frequenties in the .inf-files
(windows hardware information files )

Good luck,

If video card configured differently in Linux screen can look shaky
Try tuning the videao settings on-line with:
xvidtune

Once they look OK, you have to manually update the settings
in your XF86Config file.
