Make sure your monitor's settings for HorizSync and VertRefresh in /etc/X11/XF86Config-4 match the settings in your owner's manual. If you don't have your manual, you can usually get the information from the manufacturer web site.

My monitor is a CTX5655. The manufacturer spec's are HorizSync 30-55, VertRefresh 50-110, & DPMS = Y. When using the LiveCD my screen resoulution is 1024x768 @ 60hz. On my hardrive installation my only options are 640x480 or 800x600. I've checked the XF86Config-4 on both the LiveCD and hardrive installations and they both agree with the mfg specs... now what? I would really like to run 1024x768.
You may be missing a mode for 1024x768. Here's that section from my config file:
Code:Section "Monitor" Identifier "Generic Monitor" HorizSync 30-95 VertRefresh 50-180 Option "DPMS" EndSection Section "Screen" Identifier "Default Screen" Device "NVIDIA Corporation NV34 [GeForce FX 5200]" Monitor "Generic Monitor" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1600x1200" "1280x1024" "1280x960" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480" EndSubSection EndSection

this is what mine looks like:
Code:Section "Monitor" Identifier "Generic Monitor" HorizSync 30-55 VertRefresh 50-110 Option "DPMS" EndSection Section "Screen" Identifier "Default Screen" Device "Silicon Integrated Systems (SiS) 530/620 PCI/AGP VGA Display Adapter" Monitor "Generic Monitor" DefaultDepth 24 SubSection "Display" Depth 1 Modes "1024x768" "800x600"
I see only a subsection for color depth "1". What do you have in the subsection for color depth "24"?

Color depth 24 is the same as 1... I didn't post it all to save space.
This really has me puzzled... as it does for others too.
When I go to "Computer, System Configuration, Screen Resolution" I'm given a choice of 2 screen resolutions, 800x600 and 640x480.
When I look at the XF86Config-4 it shows 1024x768 and 800x600.
Why doesn't the "Screen Resolution" box display the same values of "XF86Config-4"?
Is there another file somewhere that needs updating to allow me to use 1024x768 like I'm able to do with the LiveCD -or- is there something I could copy from the LiveCD settings and paste into the Hard Drive install that would allow 1024x768?
Aside from this,I really like Ubuntu...
I think the screen resolution applet works independently of X. Try pressing CNTRL+ALT++ or - and see if that has any effect. If the 1024 resolution is listed first, X should use it by default. Other than that, I'm out of ideas.

It's going away in the next X release, which I hope to upload today or tomorrow or so.Originally Posted by Rancoras
