Guest ravikumar Posted July 21, 2006 Report Share Posted July 21, 2006 Folks, I got a free Dell flat panel LCD monitor. (1907FP). When I hook it up to my linux box (I bought it from HP, and it runs Mandrake 10.0) and reboot the machine, I see the boot msgs fly by. But when it tries to bring up X , the screen blanks out with a msg 'Cannot display this video mode". I don't have a graphics card, (using the default on the motherboard, something from Intel). My question is, should I buy a graphics card? Or can I just change the settings in my linux machine to make it work with the monitor. Thanks, -ravi Quote Link to comment Share on other sites More sharing options...
tyme Posted July 21, 2006 Report Share Posted July 21, 2006 welcome to the board! you'll need to change the settings. you're just using settings that your monitor doesn't like. when you get the message "cannot display this video mode" trying hitting CTRL+ALT+F1, and if you get a login prompt login as root and run XFdrake. here you can change the monitor settings to match the monitor you have connected (vertical sync, horizontal refresh, resolution, etc.) Quote Link to comment Share on other sites More sharing options...
Guest ravikumar Posted July 24, 2006 Report Share Posted July 24, 2006 This helped. Thanks. I had to select 1024x960, 8bb (don't know what 8bb means). Other settings gave blurred images. However, even with this, the graphics (logos etc.) appear garbled. However if I open an rxvt terminal, I can get work done. One thing that comes to mind is that XFdrake does not allow all parameters to be altered. (for example hsync/vsync frequencies etc.) If I choose to make the modifications to X86Config file manually, how do I restart 'X'? Rebooting each time takes a long time. In other words, I need a 'test' mode that XFDrake provides to experiment with other attributes of the monitor settings. Quote Link to comment Share on other sites More sharing options...
tyme Posted July 24, 2006 Report Share Posted July 24, 2006 you'll probably want to edit /etc/X11/xorg.conf if you're using a more recent Mandriva version as they switched to Xorg. To restart X you can probably just press CTRL+ATL+BKSP, although if that doesn't work use the CTRL+ALT+F1 i mentioned earlier and do service dm restart as root user.
