[SOLVED] Resolution woes

[virtuapai]

- 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 1024x76". 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.

Hi and Welcome !

I have SiS card in one of my machine and native sis driver is working fine in 10.04.
Execute this in Terminal :

lspci | grep -i vga
grep -i driver /etc/X11/xorg.conf

Post output here.

lspci | grep -i vga :

01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 630/730 PCI/AGP VGA Display Adapter (rev 21)

grep -i driver /etc/X11/xorg.conf :

Nothing happened.


Thanks for your support.

Press Alt+F2 and type this

gksu gedit /etc/X11/xorg.conf

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

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.
