How to fix my screen resolution
Hi,
I just installed my Fedora Core 3 on my laptop. My screen is native resolution of 1280x768.
Can somebody teach me how to get this resolution. 
Thanks |

look at your xorg.conf file. It should be in the /etc/xorg folder. Look at the monitor section something like:
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unknown monitor"
# HorizSync 29.0 - 49.0
# VertRefresh 0.0 - 60.0
Option "dpms"
ModeLine "1280x800"
EndSection
need to add your resolution there, reboot and then it should show up in your control panel under "Periphials". That is if you use KDE.
What window manager are you using?

hmm I changed it to
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unknown monitor"
# HorizSync 29.0 - 49.0
# VertRefresh 0.0 - 60.0
Option "dpms"
ModeLine "1280x768"
EndSection
and now it wont boot up. Its stuck at the checking stage for kernel or something.

Try starting at a lower resolution. Just to see if it still is working. Or your moniter might not support the horizontal sync and vertical refresh your set at. Becareful with that.

I googled for a ModeLine with screen similar to mine (14" widescreen at 1280x768)
I found HP laptop with similar specs and used their modeline:
ModeLine "1280x768" 83.77 1280 1336 1616 1728 768 770 782 808
...and it worked ^^

There is a program called 'gtf' which can calculate the modeline for you.
gtf -x 1024 768 60
will display a modeline for "1024x768"@60hz vertical refresh.
It is part of the XFree86/Xorg installation, so you should alread have it.
