    Red face Reset resolution before linux starts


    Hi there, wonder if any would help a linux newb!!

    I am running Mandriva 10.1 on a pc that also has windows. Using LILO as boot menu.

    In Mandriva, I changed my screen resolution and refresh rate to something my screen can't handle. So whenever I try to start Mandriva, my screen flickers and flashes and the screen's OSD pops up stating it is "set at a res and refresh that it can't handle".
    I can start windows normally.

    Is there a way I can change a "users" screen settings without starting Mandriva.

    Could someone give me a step by step (I am a complete newbie to Linux)

    Many thanks.

    HI !

    check this thread to set correct resolution and edit xorg.conf accordingly.
    for refresh rates, look for 'Section Monitor' in same file.

    Code:
    Section "Monitor"
    	Identifier	"Generic Monitor"
    	Option		"DPMS"
    	HorizSync	31.5-57.0
    	VertRefresh	50.0-70.0
    EndSection
    before setting refresh rates, check your monitor manual. incorrect rates can harm your monitor.

    It is amazing what you can accomplish if you do not care who gets the credit.

    Reset resolution before linux starts

    I'm newbie too, and have same problems with lcd display and also CRT monitors

    Look back of the LCD or monitor and see the max refresh rate . e.g.70 Hz
    Go into text mode ALT+F1 , login and go to /x11/xorg.conf and change the refresh rate to max value of yr monitor . To mee it works .
    Good luck ,
