I have a core i5 system with intel motherboard DH67CL. my monitor can support max 1366x768. First the max screen resolution was 800x600. i downloaded and installed intel display drivers from

http://fr2.rpmfind.net/linux/RPM/fedora/devel/rawhide/src/x/xorg-x11-drv-intel-2.19.0-1.fc18.src.html

after installing the drivers, i got 1024x768(4:3) as a bonus but still cant get 1366x768 (16:9).

any help would be appreciated

I am not a expert on hardware ( so I do not know if your hardware is recent or not ), but I would suggest to test a fedora 17 livecd to see if the issue is fixed.

Can you post the output of xrandr, and the content of X ( /var/log/Xorg.0.log ) ?

My problem is solved. the procedure i did was

After entering root


# xrandr -q

i got

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2
848x480 60.0
640x480 59.9
HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis)

then i entered my required resolution

# gtf 1366 768 60

this gave me output

1368x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 85.86 MHz

Modeline "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync

copy the above line and paste with the following command

xrandr --newmode "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync

then

# xrandr --addmode VGA1 1368x768_60.00

then


xrandr --output VGA1 --mode 1368x768_60.00

problem solved. am happy :D
