view story

http://unix.stackexchange.com – Here is the configuration: Debian 6.0.6 Kernel: Linux nardev 3.2.0-0.bpo.3-amd64 NVIDIA Driver Version: 295.59 Monitor #1: acer 22" 1680x1050 Monitor #2: acer 19" 1440x900 Goal is to make them work in TwinView one next to another. Monitor #1 is connected to regular VGA port and I can set it normally via nvidia-settings. Monitor #2 is connected via mini displayport, through some cheap "mini displayport to VGA" that I got from ebay. Unfortunately, I can't make this second one work properly. In nvidia-settings it doesn't offer me proper resolution. Maximum that is offered is 640x480 althou (HowTos)
