Hi everybody!
I want to explicitly set the video mode used by X server. Generally, X works with the default xorg.conf, generated with X -configure. But the picture is unstable: there are tiny waves that I wanted to get rid of. The xorg.conf manual page describes how to set mode to be used. First, I generated the Modeline with gtf, then inserted the line to the Monitor section and referenced it in the Display subsection. Probably, my config is incorrect because it is simply ignored, and X server starts always with the same resolution and refresh rate 1024x768x85Hz.
I wanted to ask if this is the correct way of setting the resolution / refresh rate.

/var/log/Xorg.0.log is quite a long file, so I would attach it if this is necessary.
Apart from that - does gtf generate correct Modeline to be used with Xorg 7.3?
I tried moving Modelines directly to Monitor section and to Modes section, tried using the VESA modes reported in Xorg.0.log; the result is always the same.
Thank you in advance!
