    Unable to configure screen resolution for 15.2" LCD scr

    hi folks,
    i have just installed Fedora Core 1 on my Benq Joybook 8000 laptop which, unlike most other laptops, sports a 15 inch lcd monitor ( 15:10 screen aspect ratio). The graphics card is nVidia GeForce4 420 Go 32M, which is recognized by Fedora and installed properly.

    During installation, Fedora detects an "unprobed monitor" but there were no other monitor types that I can choose from the list that suits my monitor resolution, which is 1280 x 854. The closest is 1280 x 960 under generic lcd. After the installation is complete, I tried to configure the screen resolution by accessing Display from the start menu. However, the options were limited and of course, 1280 x 854 wasn't one of them.

    Some intensive googling brought up suggestions to tune the sync frequency range for the monitor (horizontal and vertical sync). Iunfortunately, I wasn't able to find this information in my laptop's specifications manual ( nor on the product's website). Besides, Fedora warns me of possible screen damage (during installation) if I set this information incorrectly. I am not sure...but somehow i feel this isn't the right way to tackle the problem too.....

    I have installed RedHat Linux 9 before with the same problem. With Fedora, I thought this might be averted. Alas!

    Can some venerable folk out there help me with this? A zillion thanks!

    is that 1 of those crazy widescreen laptops? are they actually practical or just a gimic?

    anyway, u could edit ur /etc/X11/XFree86-config file and change the line "1280*960" to "1280*854" (in the screen and monitor sctiosn if availible)

    It will be fairly hard to fix it without the frequency specifications. I find it strange that your monitor isn't I2C-probeable, though.
    The stuff about screen damage is of no worry. It applies mainly to really old (about pre-95) CRT monitors that aren't constrained. LCD monitors will certainly not be affected at all.
    I suggest that you send a mail to the manufacturer's support and ask them for the frequencies.
    You could also try to run xvidtune and invent a video mode of your own.
