I have slackware64 13.37 installed on my new laptop, whose display resolution is 1366x768, but it will only display at 1024x768, stretched to fill the whole screen.
of which only /etc/X11/xorg.conf-vesa refers to monitor settings. I completely removed this file and rebooted, but it made no difference. I have also altered this file's content by adding "1366x768" to each relevant line in the Monitor Section, thus
Code:
Section "Screen"
Identifier "Screen 1"
Device "VESA Framebuffer"
Monitor "My Monitor"
# If your card can handle it, a higher default color depth (like 24 or 32)
# is highly recommended.
# DefaultDepth 8
# DefaultDepth 16
DefaultDepth 24
# DefaultDepth 32
# "1024x768" is also a conservative usable default resolution. If you
# have a better monitor, feel free to try resolutions such as
# "1152x864", "1280x1024", "1600x1200", and "1800x1400" (or whatever your
# card/monitor can produce)
Subsection "Display"
Depth 8
Modes "1366x768" "1024x768" "800x600" "640x480"
EndSubsection
Subsection "Display"
Depth 16
Modes "1366x768" "1024x768" "800x600" "640x480"
EndSubsection
Subsection "Display"
Depth 24
Modes "1366x768" "1024x768" "800x600" "640x480"
EndSubsection
Subsection "Display"
Depth 32
Modes "1366x768" "1024x768" "800x600" "640x480"
EndSubsection
EndSection
This also had no effect on the actual display, I still get
Code:
~ $ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 0.0*
I have no clue what gamma may be, but xrandr complains of its unavailability every time I run it, so I'm guessing that is the sticking point here. Any suggestions?
And we should really look at the /var/log/Xorg.0.log file, too. Only having 1024x768 as a supported resolution makes me think that you may be using the vesa driver.
I would remove the mods from xorg that you don't want, also attention with the depth cos if it is higher than your video card support it wont set the desired resolution or it will shrink it with some weird size.
Lets say your card only support 16bit depth so the sections monitor and screen will be something like(example):

Xorg.0.log is attached

Reason: Reloading Xorg.0.log
Your laptop is using the AMD Radeon HD6320, which is inbuilt into your CPU. This chip is simply too new to be known by the radeon driver from Slackware 13.37, therefore the system uses the vesa driver. It may help if you install the newer kernel, Mesa and libdrm from /testing, if not it definitely will work with AMD's proprietary driver.

Could you post the output for:
Code:
lspci | grep -i vga
and:
Code:
dmesg | grep -i vga
To figure out what hardware it is and how it is been used.

Your example code looked like it came from xorg.conf, which I did not have originally (though I have since generated it), what I had is xorg.conf-vesa, which has a rather different setup. As soon as I finish this I'll try adding the appropriate mode line to /root/xorg.conf.new, and see if it works (what it gives me now is a blank screen).
Code:
root@a:~# lspci|grep -i vga
00:01.0 VGA compatible controller: ATI Technologies Inc Device 9806
root@a:~# dmesg|grep -i vga
[ 8.312887] ACPI: Video Device [VGA] (multi-head: yes rom: no post: no)

Thank you, I was wondering myself if the hardware was too new, when I bought the laptop there were no user reviews for it, but newegg's price was so low I couldn't resist. If AMD has a proprietary linux driver, I'll go that route first.
You linked to version 12.2, the current version is 12.3. AMD releases an updated driver every month, I recommend to always get your drivers from the manufacturer's website. That way you will always get the newest version and you don't have to trust a third party that the driver is not modified.
