Unable to change screen resolution * [SOLVED]

Alberto Ferreira · 2009-02-02 15:59:47

Hi, I am installing Archlinux and I have read the Wiki but I still couldn't solve my stupid little problem: Changing screen resolution

Could someone tell me where to change this? From what I understood by reading the wiki, this should be configured in the xorg.conf but I don't know in which line. Also I'm also afraid of putting the wrong refresh rates.

I have a Samsung BW32 that I wish to run at 1680*1050 at 60Hz

Thanks

This is what I use... the relevant sections.

Also I use the nvidia driver, so you might want to ignore the options in the screen section. The HorizSync and VertRefresh are specs for a Dell 2005FPW, but I think they are fairly generic values. Hope it helps.

Section "Monitor"
Identifier "Monitor1"
VendorName "DELL"
ModelName "Dell 2005FPW"
HorizSync 30.0 - 83.0
VertRefresh 56.0 - 75.0
ModeLine "1680x1050" 119.0 1680 1728 1760 1840 1050 1053 1059 1080 -hsync +vsync
Option "dpms"
EndSection

Section "Screen"
Identifier "Screen1"
Device "Device1"
Monitor "Monitor1"
DefaultDepth 24
Option "UseDisplayDevice" "DFP-0"
Option "IgnoreDisplayDevices" "TV-0"
Option "NvAGP" "3"
Option "RenderAccel" "true"
Option "AllowDDCCI" "true"
Option "AllowGLXWithComposite" "true"
Option "AddARGBGLXVisuals" "true"
Option "UseEdidFreqs" "true"
Option "UseEdidDpi" "false"
Option "DPI" "98 x 97"
Option "HWCursor" "true"
SubSection "Display"
Depth 8
Modes "1680x1050"
EndSubSection
SubSection "Display"
Depth 15
Modes "1680x1050"
EndSubSection
SubSection "Display"
Depth 16
Modes "1680x1050"
EndSubSection
SubSection "Display"
Depth 24
Modes "1680x1050"
EndSubSection
EndSection

On another note, please do not use obnoxious thread titles. Chances are less people will be willing to help you.

Edit: Thank you.

Seemed a little more desperate than obnoxious in the title. Actually if you google 1680x1050 and xorg.conf you'd find tons of examples. That's the first thing I did when I set up X on my system. If I ask for help in the forum, which is seldom, it's usually a last resort after exshausting tons of searches. You end up learning better when you figure stuff out that way. : )

Another thing that helps is checking your /var/log/Xorg.o.log, and google any any WW or EE warnings and errors. Sometimes the log file will tell you what needs to be changed or removed. I did this until I managed to get Xorg log warning and error free.

They're not mutually exclusive...

Thanks guys and I'll keep that in mind next time

Btw, the line "RenderAccel" is supposed to be in the "Device" or "Screen" section?

I think most people list this in the device section, but I think it can be listed in either the device or screen section. According to the man page, these various driver options can be listed in the screen section. I'm sure this is probably why I listed it in the screen section.
