Hi Matthew  
from log file, I found the lvds timing after X starts is almost the same with that of vbios setting -1024x600. My question is in UMS before X start every thing works fine, and after X start get back? If yes could you please try below timing by xrandr ? 

Modeline "1024x600_vbios" 41.42  1024 1072 1184 1200 600 601 604 625

Thanks for your help.

Ma Ling,

I tried what you asked for, but the screen remains blank.  Yes, you are correct the console works fine with both KMS and UMS, only when I start X the problem occurs.

I did the following:

$ xrandr --newmode "1024x600_vbios" 41.42 1024 1072 1184 1200 600 601 604 625
$ xrandr --addmode LVDS "1024x600_vbios"
$ xrandr --output LVDS --mode "1024x600_vbios"
$ xrandr 
Screen 0: minimum 320 x 200, current 1024 x 600, maximum 2048 x 2048
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1024x600+0+0 (normal left inverted right x axis y axis) 220mm x 129mm
   1024x600       60.0 +   65.0  
   800x600        60.3  
   640x480        59.9  
   1024x600_vbios   55.2*

The screen remains blank.

Any ideas?

Matthew.

Thanks for your help.

xorg log file UMS (PATCHED)

Ma Ling,
I patched the driver and attached the log.

just FYI, ling. the message of 

 DEBUG_1 fixed mode line
(II) intel(0): Modeline "2136x17"x0.0   10.24  2136 2392 2395 2396  17 17 17 23 (4.3 kHz)

is a bug# 22529 which was just fixed by Jesse.

hi Matthew
What's  your laptop Model No, our machine is MSI Wind U100.
Because our MSI WIND netbook U100 works fine in version 2.7, could you kindly please download 2.7 version from http://xorg.freedesktop.org/archive/individual/driver/xf86-video-intel-2.7.1.tar.bz2, then upload log file and output from command $lspci.

Thanks for your help.

Ma Ling,

It is a U100 also.  I know that some combination of drm/xorg/driver has worked before (for example: stock OpenSuSE install).  My current system is Gentoo/unstable and 2.7.1 release is failing too.  I even tried 2.6.x and still failed.  Could something else be the culprit?

Matthew, we have tested msi wind 100 and 100 plus successfully under following enviroment, could you please verify it again?

Thanks a lot
Ma Ling
