E177FP Natty low resolution

Asked by Bob on 2012-08-12

I have been using Natty with an old Dell monitor. I just replaced it with a Dell E177FP flat panel and only get 800x600 resolution, not the 1280x1024 this monitor will produce. Is there a way to change this?

Thanks

I suggest you upgrade to Precse soon (Preferably via fresh install) as Natty is EOL in October.

Can you give the output of:

sudo lshw -C display; lsb_release -a; uname -a

Thanks

Yeah those SiS things need an xorg.conf file, basically they suck:

If you run:

gksudo gedit /etc/X11/xorg.conf

and add the below text.

Section "ServerLayout"
    Identifier "Layout0"
    Screen 0 "Screen0" 0 0
EndSection

Section "Monitor"
    Identifier "Monitor0"
    VendorName "Unknown"
    ModelName "Dell E177FP"
    HorizSync 15.0 - 46.0
    VertRefresh 49.0 - 61.0
    Option "DPMS" "off"
    Option "DPI" "96 x 96"
EndSection

Section "Device"
    Identifier "Device0"
    Driver "sis"
    VendorName "Silicon Integrated Systems"
    BoardName "661/741/760 PCI/AGP or 662/761Gx PCIE VGA Display Adapter"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    DefaultDepth 24
    Option "TwinView" "0"
    Option "metamodes" "1280x1024_60 +0+0"
    SubSection "Display"
        Depth 24
    EndSubSection
EndSection

Save the new file and reboot. If you don't get a desktop then reboot and hold SHIFT, select recovery mode then select root, you can now run:

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

NOTE: The X in X11 is capitalized, Linux is very case sensitive so it must be used.

actionparsnip:

This did not change the resolution or cause it not to boot.  I apologise but there are a couple of things I did not mention earlier: I use a login on this computer. Since changing the monitor (start of problem), the login screen has been at low res. After I login a window pops up that says: "Could not apply the configuration for monitors" then has a list where each line starts with "CRTC 279: trying mode" and gives the resolution and hz tried.

This was true before I tried your suggestion and still happens.

thanks

If I get a video card, can I disable Sis video? Any recommendations?

Your BIOS should allow you to disable the device. Nvidia have great Linux support, check what connectors your system has (AGP, PCI-Express etc) before you buy

Can you help with this problem?
