ok i recently got redhat to install and changed the refresh rates in the X configure useing emacs, and attempted to startx and got the error
(EE) trident(0) no valid modes found
(EE) screen(s) found but unable to use (or something like that cant remember)
someone had tried to help me but she could not figure out what to do, can anyone PLEASE PLEASE help me, ive been trying forever to get linux and failed miserably every time and really need some help, and every other message ive posted never got an answer, if im asking the wrong type of questions im sorry for that, im VERY new to linux and just trying to get started

if im lacking more info please tell me and ill get it, ive been trying to figure it out all night and i just cant figure it out

That seems to indicate something like it can't find a driver for "trident" whatever that is (presumably a graphic's card). Hence it can't find screens that will work with whatever refresh rate's you changed to.

I've you've got alternate access to the net (dual boot windows or something like that) and find out the spec for the monitor or if you've got instructions for your monitor/screen, then you could change it back to the default values.

Then reboot and see what happens.

it is my graphics card, as for my screen it is one of those "unnamed" screens, i got the model number off that back but thats all, and when searching the only thing that came up is royal informative, but didnt find anything of use for it at any of the sites =\

does anyone else have this same monitor or can point me in the direction of where to get the specs for it? i believe its a royal information company monitor model DH-1764

ok i got some help from some people and they had me add some lines, which were: under driver which we changed from trident to vga, we put Option "noaccel" then in display we put Modes 640 480 there was a line above that which i cant remember (im dual booting onto windows right now) and also changed depth and default depth to 8 and now xwindows is loading but its HUGE and the top half of the screen is gone, even the mouse gets lost in it could someone give me some ideas on what to do from here because my friend who had helped me is lost as well

Well if you've managed to get something on screen, then I would have thought that you're not too far off.

Have you tried putting different resolutions into the same line that you put the 640 and 480 ? or you may just be able to change it temporarily by hitting ctrl - or + (but use the - and + keys on the numeric keyboard section - that might help).

Oh and note down any changes, so at least you should be able to get back to "square 1".

The mouse getting lost maybe to do with having the screen set to that res, means that the "virtual screen" has the cursor on that section, though normally it should get to the edge of the screen and then move the screen image across. Weird!
