Monitor doesnot come on after changing Screen resolution

I'm running Madrake 9.1, I went into the Mandrake control center and changed my screen resolution from 800x600 to 1280x768 and now my monitor doesn't come on after the initial boot up it goes thru the loading process but when it gets to the actual login the monitor goes dead.
My question is can I telnet into the pc and change it back from the command line and if so what is the command that I need to use?? And yes I have successfully tenet into the pc and logged on as root.

arn0ld

init 3
or
if you are familiar with /etc/X11/XF86Config-4 , you can edit that - look for "Modes" lines

otherwise, reboot into runlevel 3
if using lilo, init=3 (i think)
or edit inittab change id:5:initdefault to id:3:initdefault

or, when you boot into blank, try
ctrl-alt+ (or-) +/- on numeric keypad
ctrl-alt-f1 to get console login, init 3

(slight variation/addition/cimbination with arn0lds first...:-):
switch to runlevel 3 first with:
telinit 3
before running XFdrake, so that you can be sure the "test" option will work OK. (I'm not sure it wouldn't work without going to runlevel 3, but better safe than sorry:-).

no linux installation should be without
http://www.toms.net/rb/download.html - toms linux on a diskette. Like 3 swiss army knives

of course, if everyone had toms, forum traffic would probably drop by 25%

BTW, my XFdrake requires XFree86-SVGA - is this part of a standard mandy install?

Lets see.... Hmmm, where did I put that 9.1 ... Nope (and I don't see any such dependency).
How old is that XFdrake arn0ld? In olden times, it used to be that way (ISTR at least:-)... if you mean XF86_SVGA (version 3.3.x)... don't really remember if it required, but it might've since back then Mdk came with a choice between version 3 and version 4... (no such choice anymore;), but on a 9.1 it should just depend on the normal X (duh, version 4.3.0:-), some perl-ncurses bindings and (of course... since it is a perl-program) perl.
Agree, tomsrtbt (and/or knoppix) should be in everyones toolbox. For the straight question though, telnet and XFdrake should be it:-).

Sorry Glen didn't mean to confuse. I am running 8.2. However, I do have 9.1 and 9.2 CDs. FYI, I ran rpm -qRp drakxtools-9.1-26mdk.i586.rpm on my 9.1 CD.
This displays the dependancies. It did not show any requirement for XFree86-SVGA.

But, neither does rpm -qR on my drakxtools-1.1.7-98.1mdk - I believe in 8.2, the requirement is generated dynamically from some perl module.

Good that we saw the same deps;-). No need to apologize.... I'm confused most of the time anyway:-):-).
Be well arn0ld.

Sorry for the slight off-topicness cmmonline. Do you need more help with this issue? Don't be shy with feedback!-)
