    Hey,

    I have a linux server with some software on it that I haven't used in a few years. I cannot reinstall as I don't have the correct disks anymore for the software. When I boot up the server just before I get to the user interface it says the refresh rate is messed up so I cannot get in. From here I press f2 and I get a login screen but I cannot remember my password... I was wondering if anyone knows of a way to bypass the linux login or how I can sort out the resfresh rate problem. I have checked online and found a software called Kon-boot but I can't afford to trust it just in case as its freeware and doesn't sound to legit. Usually I would try it but I just can't on the off chance it screws me..... :P

    kon-boot works fine.
    Another option is to boot from a live CD/USB, mount your real Linux install and edit the /etc/passwd file.

    If you remove the "x" between the two ":" 's after your username it will let you logon without a password on next reboot.

    Thanks a million, I was able to change the login by logging on as a single user but now I am looking to change the display as anytime I get to the login screen the display goes black and I have to use ctrl, alt, f1. I was just wondering is there any commands that would enable me to change the settings so that I can log into the user interface rather then just the command line. I am using a linux redhat server system.

    PS Sorry bout all this, am a huge linux newb kind of thrown in at the deep end here lol :P

    Which version of Redhat is this?
    "cat /etc/redhat-release" should tell the version.

    I'll try to guess, that it's using xorg, rather than the old xfree...
    If it's a bit oldish version the command to use might be

    system-config-display --noui --reconfig

    Or for something newer...
    xrandr --help
