Ubuntu: DVI-VGA adapter problem


Is it possible to add unsupported resolution when monitor is connected via DVI -> VGA (passive probably) adapter? The problem is that the monitor (Acer AL1916W) is reported as CRT monitor, mainly because it connected indirectly to the GPU (nVidia 9800GTX+ using driver v310.14 @ xubuntu 12.10). I've tried adding custom resolution with xrandr, but result was following:

xrandr --newmode "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync    xrandr --addmode DVI-I-0 1680x1050_60.00    X Error of failed request:  BadMatch (invalid parameter attributes)  Major opcode of failed request:  153 (RANDR)  Minor opcode of failed request:  18 (RRAddOutputMode)  Serial number of failed request:  31  Current serial number in output stream:  32  

The persists on windows too, but it can be fixed by adding custom resolution from nVidia Control Panel.

Thanks in advance!


I had the same issue. Please review my document how I fixed it.


I hope it would be helpful.
