Angry Please help me to fix the screen resolution problem in dell inspiron E1505


Hi,

I have installed Fedora 5 in Dell inspiron E1505 duo core laptop. The video card is ATI MOBILITY™ RADEON® X1400 HyperMemory™ and LCD size is 15.4". The maximum resolution is
1680 X 1050. However, in Administration->Display->Hardware, it says "ATI Technologies Inc Unknown device 7145" even after configuration. The "hwbrowser" command does not show video card.

I fixed the resolution to 1680 X 1050 in Administration->Display->Settings. There is another place also to fix the screen resolution: at Preferences->Screen Resolution. But the maximum value here is only 1400 X 1050. I fixed to this value.

The problem is:

The image is streched along horizontal direction so that circle looks like an ellipse.

Here is 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"

I installed the latest driver from ATI site but that showed some weird behavior so I uninstalled it.

Could you please help me to fix this horizontal streching problem. I appreciate your help.
Thanks.
Manoj
