    LCD using non-native resolutions (in Ubuntu)


    Hello; my name is Tomas and this is my problem:

    I just installed Ubuntu Breezy on my work's laptop (the first laptop I've ever used, BTW), and I noticed everything looks unacceptably blurry with any resolution other than 1024x768.

    I went to Wikipedia, and I found out (pardon my ignorance) that LCD monitors only work well at their native resolution, and they scale badly with any other.

    So, I'd like to know if there's any setting to solve or minimize this effect in Ubuntu, because high resolutions really hurt my eyes (I'm used to 800x600!).

    I already tried to configure the video card (ProSavage) settings, but couldn't find an entry for that in Ubuntu's menus. And I also read about some command-line tools (like Xconfigurator and XF86Setup), but couldn't find them even in Synaptic.

    BTW, I saw (somewhere in a terminal window; can't remember where exactly) that the output is set to CRT instead of LCD... could this be a cause? If so, how do I change that?

    Before someone suggests it, I already know I could just increase the font size and leave the resolution as it is, but many things don't look right after that... not to mention everything non-textual still looks tiny.

    Any suggestions? Thanks in advance!

    PS: I'm sorry for the double post, but I couldn't decide which forum was the most suitable.

    I guess you use the xfree86 xserver not the xserver-xorg?
    doesnt really matter thou.

    log in a terminal as root.
    su and than the passwd

    than open midnightcomander
    mc

    than go to your X11 folder usually /etc/X11/ than mark the .conf file if you use xorg it is xorg.conf otherwise xfree.conf or something like that, there should just be on real .conf file. Mark this one ans open it by pressing F4 than scroll down till you find something like:

    SubSection "Display"
    Depth 1
    Modes "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection "Display"
    Depth 4
    Modes "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection "Display"
    Depth 8
    Modes "1024x768" "800x600" "640x480"
    EndSubSection

    and so on ...

    is there your resolution listed is yes it should work if not just add it and save it with F2 than exit.
    Now it should start by default in the highest reselution but you can change this in a running xserver.
    In KDE for example go to k-menu/system/KRandRTray (Sreen Resize & Rotate)
