Ubuntu Resolution Problems!!


-I have another one of those resolution problems that many have had over the years. I had xp, and no longer liked it and decided to try out ubuntu. When I first installed the os, everything was fine(started with 9.10 just shy of the release of 10.04). Two days after I installed 10.04, my screen resolution defaulted to 856x600 and I lost the ability of using higher resolutions of 1024x768 and above. What do I need to do to get those upper resolutions back?

-I tried using the terminal to up the res and I was met with: "xrandr screen resolution cannot be larger than 856x600 (desire size 1024x768)". When I selected 1024x768 res within the monitor section, I was met with: "could not set the configuration for CRTC 135 ?

-If this could help here is what I am working with:
1.1 gig intel celeron
40 gig Hdd
Sis 630/730 graphic card
p992 dell monitor.

-Help would be much appreciated. Other than this, my experience have been well and like this much more than xp.

Take a look here, especially post #13 & #14. This might be helpful as well (it's titled color depth, but also shows some modelines for resolution.

Thank you for your support. I tried using gksudo displayconfig-gtk, but it doesn't do anything in ubuntu 10.04. I tried doing the sudo gedit /etc/X11/xorg.conf (as well as sudo gedit etc/xorg.conf) and tried to edit(the blank page) and nothing changed. Do you have any other suggestions. Your time and patience is much appreciated.

still no luck....Was given a solution on another forum. For those of you who may encounter the same problem that I had, here is what you can do:

Press Alt+F2 and type this
Code:

gksu gedit /etc/X11/xorg.conf

It will open an empty xorg.conf file in Gedit with root privileges.
Paste these contents in file :
Code:

Section "Device"
Identifier "Configured Video Device"
Driver "sis"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
HorizSync 31.5 - 70.0
VertRefresh 50-160
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1280x1024" "1024x768"
EndSubsection
EndSection

Save file and reboot machine.

Well and what you may want to do is to install the drivers for your computer. This is what fixed mine up.
