problem setting screen native resolution 1680 x 1050

Asked by jdelima on 2008-02-15

Binary package hint: yelp

hardware (lcd monitor): o.b.disp2.1_22w (belinea o.display 2 22" wide)
Leadtek pcie card nvidia nv43geforce 660
resolution setting cannot be maintained
screen deteriorates into moving fine vertical and horizontal lines of unblended colors and the horizontal lines constantly pulsating upward.

note: i'm not sure whether this is a bug or a hardware defect but when i set the resolution to 1680xs1050 the screen seemed to work perfectly. the monitor is new and i just connected this yesterday morning.

Hello

you can manually reconfigure your X server to cater to video driver parameters with the command: (In a terminal applications -> accessories -> terminal)

sudo dpkg-reconfigure xserver-xorg

And if you do not want to answer all the questions but only those which are rated with high priority:

sudo dpkg-reconfigure -phigh xserver-xorg

Have a try and keep us informed

Bhavani Shankar.

yes, i did exactly as Bhavani Shankar suggested and i'm now positive that the problem is with the hardware. i connected the monitor to another computer running on windows xp 2d ed (the manufacturer say it is a Microsoft OEM vendor) and the problem is even worse. thank you all for for your kind help.
