Display artefacts under X

Symptom:

While everything gets displayed o.k. in textmode, the picture shows perturbances under X.

Here are some common symptoms :

Cause:

One or several of the following quantities don't match the specifications of your monitor :

The specifications for your monitor usually don't imply the simultaneous usage of all maximal settings, but are meant to be independant limits. Furthermore, due to the aging of the monitor, it might be impossible to get a stable picture with settings, that work for a new monitor.

Solution:

Reduce the refresh rate, horizontal line frequency, color depth and resolution step-by-step, until you get a satisfactory picture. A big decrease of one quantity might allow to increase another quantity. Don't use the predefined settings for special monitors in SaX, XF86Setup or xf86config, but enter the desired settings manually in the appropriate places. However given setting should be used as a first hint, which settings are useful.

Example :

 hsync 31,5 - 90 kHz predefined
       31,5 - 89 kHz
       31,5 - 88 kHz
       31,5 - 87 kHz
etc.
