Argh, resolution problems (max: 800x600)

Asked by Lamperouge on 2011-03-06

Hello everyone. I know that a lot of people have asked this question before, but I'm literally tearing my hair out trying to solve this on my own and I just seem to be going in circles. I'm a complete newbie to not only Ubuntu/ Linux systems but computing in general, so if you guys could guide me through this step-by-step like a child, I'd really appreciate it.

Now, as I'm sure you've guessed, I'm having some problems with my resolution. Basically when I go to System --->Preferences --->Monitors, my system does not detect *ANYTHING*. No monitors, no drivers, e.t.c. The most I can get is a 800 x 600 screen and some very choppy graphics (by "choppy" I mean stuff doesn't look anywhere near as nice as an Ubuntu system should look like). I would love for my system to have a 1240x1024 resolution, and I know that my monitor is capable of running it... *confused face*

Info on what I'm running:

Basically I'm running Ubuntu 10.10 alongside WIndows 7 on a dual operating system. Ubuntu takes up around 17 GB of my 250GB drive. Ubuntu is now my main operating system. I've got a ASUS X5DC laptop.

This is what I get when I enter the command "udo lshw -C video"
"*-display UNCLAIMED

Don't know if that helps you guys at all. I'm completely useless at computing, though I'd really love to learn.

yeah these things can need an xorg.conf file. I doubt you will get 3D accelleration but we can get you a better res.

If you run:

gksudo gedit /etc/X11/xorg.conf

add the below text:

Section "Device"
       Identifier "Device0"
       Driver "sis"
       VendorName "Silicon Integrated Systems [SiS]"
       BoardName "771/671 PCIE VGA Display Adapter"
       Option "EnableSiSCtrl" "yes"
       Option "DRI" "off"

Section "Screen"
       Identifier "Screen0"
       Device "Device0"
       Monitor "Monitor0"
       DefaultDepth 24
       SubSection "Display"
               Viewport 0 0
               Depth 24
               Modes "1240x1024"

Section "ServerLayout"
 Identifier " Configured"
 Screen 0 "Screen0" 0 0

Section "Monitor"
 Identifier "Monitor0"
 VendorName "Plug and play"
 ModelName "Plug and play"
 HorizSync 31.5-90
 VertRefresh 60
 Option "PreferredMode" "1240x1024"

Save the file and close gedit, reboot to test. If you don't get a display then reboot and hold shift, select recovery mode, then select root. You can now run:

mv /etc/X11/xorg.conf mv /etc/X11/xorg.conf_old

Then reboot

NOTE: The X in X11 is CAPITALIZED. Linux is extremely case sensitive so stay accurate.

Can you help with this problem?
