The problem has been solved by changing the xorg.conf file in /etc/X11/ directory. A new "Modes" section has been added and its content has been available to the "Monitor" section with the "UseModes" entry.
A new copy of the xorg.conf file has been attached. The problem rely on the automatically detected ModeLines: for the 1680x1050 resolution there are 3 discoveries by the server: 1. (**) NV(0): *Driver mode "1680x1050": 146.2 MHz, 65.3 kHz, 60.0 Hz (II) NV(0): Modeline "1680x1050" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 +hsync -vsync (**) NV(0): Driver mode "1680x1050": 146.2 MHz, 65.3 kHz, 60.0 Hz (II) NV(0): Modeline "1680x1050" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync (**) NV(0): Default mode "1680x1050": 147.1 MHz, 65.2 kHz, 60.0 Hz (II) NV(0): Modeline "1680x1050" 147.14 1680 1784 1968 2256 1050 1051 1054 1087 2. 3. The workaround The problem of a new call to dpkg-reconfigure still remains: if a new reconfiguration is made, then all the maually inserted changed are lost, and then they has to be re-entered by hand... Maybe a "dpkg-reconfigure -phigh xserver-xorg" with the -phigh option can avoid this problem, but I did not tested it yet. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
