position. SaX2 allows moving the display area left-right up-down and changing the size and eventually says that configuration is saved, but it is not. Next restart the display position is wrong again. I compared xorg.conf before adjusting position with Sax2 and after - there are no "modline" changes.

I tried xvidtune as well and it also does not save changes (though in this case I do not remember, maybe I have to manually copy modline into xorg.conf)?

I've struck this problem with 11.1. I also use a KVM box and I have found that my screen settings do not survive a log-off / log-on or reboot. They reset to something less than my required resolution. I found that if I connect the screen directly to the video port, reboot the system and then reconnect through the KVM - everything works fine.

Always prefer a hardware solution? !?

What can "modline" do here?

In my case the problem was not with resolution (video mode has been chosen correctly), but with exact positioning of display area on the screen. In old days (of Slackware), you adjusted this stuff with xvidtune. As a result xvidtune produced "modeline" for XF86Config configuration file. This line contains some fine-tuning parameters (scan start, offsets). I am not sure now, but I think that in earlier versions of SuSE/OpenSUSE SaX saved your fine-tuning automatically in xorg.conf, using the same modeline parameter in the "Modes" section of xconf.org. As I wrote in my continuation mail, after I copied the result produced by xvidtune manually into xconf.org, my problem had gone.

OK. I tried vidtune, which gave me this: (1) Vendor: --> LCD, Model: 1680X1050@60HZ Num hsync: 1, Num vsync: 1 hsync range 0: 30.00 - 66.00 vsync range 0: 50.00 - 61.00 "1680x1050" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync In xorg.conf I have this: (2) Section "Modes" Identifier "Modes[0]" EndSection Where/how does the stuff from (1) go into (2)?

In xorg.conf I have this:

(2) Section "Modes" Identifier "Modes[0]" EndSection

Where/how does the stuff from (1) go into (2)?

The last line in xvidtune output is modeline. Copy it into xorg.conf like that:

Section "Modes" Identifier "Modes[0]" Modeline "1680x1050" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync EndSection

So now when X selects the mode 1680x1050, it will adjust the settings according to this line.

Thanks. Next scheduled reboot is in a few days - we'll see ... Regards, Daniel
