Moniter is not going into proper resolution :(


Hey, very new to linux here so PLEASE excuse my cluelessness . I installed Red hat 9 and was having problems with the resolution. I posted somewhere else and they told me how to edit the Xsomething86 thing (forget what it is called). But anyway, it is now showing in the display control panel that the desktop should be scaled properly to my moniter (does this make sense?). BUT, my moniter when I check the resolution on it is still 640X480@60hz but I know my moniter can support 1024x768@85hrtz which I would like. So, my suspicion is the moniter is not being told to "change" resolutions properly in Linux. I have tried ctrl+alt+ (+)(-) btw. So what I get is Linux displays at 1024X768 but my moniter is stuck at 640x480 so I am zoomed in on parts of the screen and I have to move my mouse cursor to the edge of the screen to have it scroll around. My moniter is a Samsung SyncMaster 753df, does anyone have any idea how to fix this and why it is happening?

hmmm
maybe its the display size?
other than that everything seems fine.
just try commenting out the line in Section Monitor

DisplaySize 320 220

meaning fup a llittle # in front of it

# DisplaySize 320 220

i don't really know if that will help but its my best guess

Hey, no ones begging you to stay with linux. If you want to be strip of you personal freedoms thats you call. haha... just playing.

by the way my friend has been trying to get XP to install for a week.

ok a little troubleshooting. I'm now having a sneaking guess that its the graphics card driver.

this will flush that one out.

first comment out the radeon section as follows
# Section "Device"
# Identifier "Videocard0"
# Driver "radeon"
# VendorName "Videocard vendor"
# BoardName "ATI Radeon 9000 Pro"
# EndSection

then add the generic vesa driver

Section "Device"
Identifier "Videocard0"
Driver "vesa"
Option "UseFBDev" "true"
EndSection

this will use the generic vesa driver instead of your graphics card driver.

Ya and sorry wbout the DisplaySIze suggestion, turns out thats just the physical size of the monitor in millimeters. Shows what I know. haha

on the part:

Depth 24
Modes "1024X768" "800x600" "640x480"
EndSubSection

try changing it to just:

Depth 24
Modes "1024X768"
EndSubSection

I actually have the exact same monitor and i dunno what it is but if i put in multiple resolutions there it seems to take the lowest one first.

Talk about getting way to involved in a problem with a pretty simple answer!
ya I agree with mondaypickle.
I would try that first before changing the drivers.

I tried that, and now it can't load the X GUI. It says the dimensions defined were incorrect and then failed to load X. I tried drivers before and the same thing happened but I did it for an earlier version (forget these Linux terms :\ ). Maybe that was the problem. I should add the screen did the refreshing clicking thing 3 times trying to load X then gave me the error. Man, I am so confused ROFL. Did I mention it only recognizes the right video card connecter too? But I am not going to even worry about making dual moniters work yet , this is confusing enough as it is.

ya X is supposed to check each screen mode from the highest to lowest resolution keeping the first one that works. did you say that you tried both suggestions? It was a little hard to understand your message. sorry.
