Unhappy unable to set the resolution + bad slow referesh

i am not able to set the resolution to "1366x768" (which is the correct value according to my linux and windows installations), and besides that the screen looks very ugly and it is very slow in refreshing,

the Xorg.0.log says

(II) VESA(0): Monitor0: Using hsync value of 47.41 kHz
(II) VESA(0): Monitor0: Using vrefresh value of 60.01 Hz
(II) VESA(0): Not using mode "1366x768" (no mode of this name)
i have no idea if this is a driver problem or a configuration problem.

i am attaching both Xorg.0.log and xorg.conf in case helpful.

I do not think that 1366x768 is a standard resolution. It might be something like 1280x768.
See this wiki on graphics resolution

1366x768 is a 11/12" resolution used by many netbooks.

Anyhow, from your Xorg.0.log:
(--) PCI:*(0:0:2:0) 8086:0046:1025:0364 Intel Corporation Core Processor Integrated Graphics Controller rev 24

(II) Loading /usr/local/lib/xorg/modules/drivers/vesa_drv.so
(II) Module vesa: vendor="X.Org Foundation"
compiled for 1.7.7, module version = 2.3.0
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 6.0
(II) VESA: driver for VESA chipsets: vesa
So, you're using the standard vesa graphics driver. Try using the Intel graphics driver.

You will also want to remove the Modeline setting in your Monitor conf, and Mode setting in your Screen. You almost never need to specify these with modern screens (== Pretty much everything from the last decade).
UNIX was not designed to stop you from doing stupid things, because that would also stop you from doing clever things.

Sorry, Carpetsmoker is right. From the fine print in the wiki
Overall, several resolutions have been labeled as WXGA. These are the most common resolutions given the label (in ascending order by total number of pixels):

* 1280×720[13]
* 1280×768[14]
* 1280×800[15][16]
* 1360×768
* 1366×768[17]
There are some issue with the newer intel video drivers needing kernel mode settings (KMS) so if you have a newer chipset vesa may be what you have to work with.
