I have an 19-inch monitor with a 1366 x 768 native resolution and I'm using an ATI HD Radeon 5670. It does not detect my native resolution automatically, so I've put something like this on my xorg.conf (except for the numbers 1-9, I've put in the result of running cvt).
Section "Monitor" Identifier "DVI-0" Modeline "1368x768_60.00" 1 2 3 4 5 6 7 8 9 -hsync +vsync EndSection Section "Screen" Identifier "Screen0" Device "Card0" Monitor "DVI-0" SubSection "Display" Modes "1368x768_60.00" EndSubSection EndSection Section "Device" Identifier "Card0" Driver "radeon" EndSection
So my resolution changes, but the problem is the resolution does not fit well to the screen. Seems like some pixels to the top (around 10px) are not viewable, and the width does not fit as well, there are huge black spaces on the left and right of the screen. Adjusting width settings on monitor messes up my font. On Windows, 1366x768 works very well, any ideas how to fix this?
