1380x1024 is not a standard mode. Probably the video driver is rejecting it 
as no match to the display's EDID report.

What is your output from 'lspci | grep VGA'?

If you've repeated a typo, and what you're after is actually 1280x1024, and 
your display actually supports 1280x1024, then there are several things you 
can try, some of which Fran├žois ANDRIOT wrote about.

When there is no provided configuration utility to build you an xorg.conf 
file easily, you nevertheless can build one manually. Try using 
http://fm.no-ip.com/Share/xorg.conf-minimal-force-DPI as a starter, but with 
the DisplaySize line commented out if you don't wish to force DPI. If it 
fails initially, try adding the following to 'Section "Monitor"':

   HorizSync    28-91
   VertRefresh  55-76

If you have access to the specifications for your display, substitute the 
values it provides for the above.

In openSUSE (as well as various other distros) instead of putting all configs 
in xorg.conf, you may find it easier to use the smaller files in 
/etc/X11/xorg.conf.d/ as alluded to in 
http://fm.no-ip.com/Share/xorg.conf-minimal-force-DPI.

Something he also did not mention that could possibly help is putting the 
video mode desired on the kernel cmdline, e.g. video=1280x1024@75 or 
video=1280x1024@60.

As Fran├žois ANDRIOT wrote, your problem isn't specific to TDE. If you put 
your Xorg.0.log file where readers can see it without wrapping (e.g. 
pastebin), then someone may spot your specific problem. Likely you're using 
the VESA driver and your BIOS fails to include 1280x1024. VESA is a fallback 
you don't want to be using normally.
