Hi everybody!
I have a Dell Latitude D620 with a partition (RHLE 4 and Wxp). I´m trying to fix the resolution of the screen. it doesn't work with RHEL. My laptop has 1280x800 or 1440x900. I'm working with 1024x768, so I feel a bit frustrated, you know...

I've tried with "915resolution" rpm stuff and it doesn't work.
Please, help me.

One the graphics interface is a bit newer then what the kernel supports.
Two you might have luck by manually editing the the /etc/X11/xorg.conf by hand as root, example below;

Thanks a lot.
I've tried to modify the xorg.conf file, as you told me. It doesn't work.
Do you think I have to update something (kernel, drivers...)?
let me know.
M.

Which graphics driver is being used?? Check your xorg.conf file and post back along whith your kernel version and xorg-x11 rpm version.

uname -a
rpm -qa xorg-x11

hi. thanks again. I can show what I have found. Just below "----" you can read my xorg.conf file

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
