DL380 Linux Wavy right side of screen

[ElmerWFudd]

I have 2 DL380's: a Gen 1 and Gen 2. Linux is installed on both. Display is fine for G2. Compaq Proliant banner and POST display OK on G1, but when the Linux desktop loads, the left 1/3 of screen is OK but the right 2/3 is a wavy transposed image that is not readable. 2 different monitor give the identical result.

What is wrong with the displayed image? How can I fix it?

Try a different cable? Any other OS do that?

Forgot to ask...is this a tft monitor (for a KVM)???

It does the same thing using either of CRT monitor 10 yrs old, or a Dell flat panel 1 year old. Each monitor has its own cable. The same thing happens with a KVM, as direct connection of cables.

This wavyness only starts after POST, cpu, memory initialization, and drives complete.

The G2, with the same software, using the same monitors, does NOT do this.

I know Linux is picky with X, so it may be graphics drivers, or the parameters for video. Have you messed with those, like x and y resolution, and maybe frequency in X?

I had the same problem. I would check resolution. bumping the resolution down fixed it.
