X11 Resolution - not read from xorg.conf


I am having problems with changing my resolution. In my /etx/X11/xorg.conf file, I have the Display Modes section set to include the resolutions 1280x1024, 1024x768, and 800x600. However, when I try to use xrandr to change the resolution from the 800x600 that it defaults to, it only allows me to choose between 800x600 and 640x480. When I use startx to go into WindowMaker, it says it is using the /etc/X11/xorg.conf file, so it should work. I also know for a fact that my monitor can handle higher resolutions. I have tried changing all the x config files I could find to include the proper resolutions, but it doesn't work.

My only guesses are that it is autodetecting the hardware incorrectly, rather than using the values in the file. This may have something to do with the fact that I am running this on a laptop with an external monitor hooked up (the built in one cracked).

Please post any ideas on how to get into a decent resolution. Regards,

I never had a problem with res but from my experience linux GUI still use XF86Config file to do video card configuration and tweaks. You should do a emacs (or what ever text editor program you use) /etc/X11/XF86Config this just might solve your problem. sry I know no other way.

Edit:: umm if slackware don't have XF86Config then well sry.

Slackware uses Xorg, not XFree86, so /etc/X11/xorg.conf is the right file.

Thank you for your replies, but I already found the solution. It seems that some of the autodetection Slackware did at startup was incorrect (or maybe I entered the wrong values), and so I manually reconfigured the whole thing using xorgconfig. I believe the problem was in the video card driver - it had a default failsafe basic choice, just to make sure it would work no matter what, instead of anything similar to my actual card. Also, yes, Slackware only has a xorg.conf file, which is however still generated using the XF86 stuff. So, once again, thanks!
