Xorg KMS - Resolution Problem on EEE 1005P

Hi,

i have an EEE-PC 1005P, so it's the one with the new NM10 Chip (Pine Trail / Pine View) - it should be based on the GMA-3150 chip as long as i know.

00:02.1 Display controller: Intel Corporation Pineview Integrated Graphics Controller

The problem is, that xorg/randr detects only 2 resolultions. 1024x600 and 640x480.

Screen 0: minimum 320 x 200, current 1024 x 600, maximum 4096 x 4096
VGA1 disconnected (normal left inverted right x axis y axis)
LVDS1 connected 1024x600+0+0 (normal left inverted right x axis y axis) 220mm x 129mm
   1024x600       60.0*+
   640x480        59.9

When i try to start applications in 800x600 ( like Diablo II via wine ) they will crash on setting the output to 800x600 because this resolution doesn't "exist".

I dealt with the problem by disabling Kernel Mode Setting in the grub-bootline. Everything worked fine. xorg detected all available resolutions and for me it made no difference if KMS is available or disabled (i can wait the second when switching from tty to X wink )

Since the new xf86-video-intel package (2.10.0) was released this workaround is not available anymore. If i disable KMS in grub-bootline X won't start with the error message that "kernel mode setting" is not available and "unload intel module".

When i enable KMS, everything works fine again with 2.10 except the thing that there is only 1024x600 and 640x480...

So there are two solutions... either:
- Trying to force xorg to detect 800x600 somehow (already tried to do it by virtual screen or by setting modelines manually... but failed -_-)
or:
- Finding out, how to disable KMS again.

I know... downgrading xf86-video-intel is a third option and i will do that if nothing else will help, but the driver-changelog said that there are a lot of improvements done by this release. Especially for my chip. So i would love to find out how to use the new driver with kms and 800x600 smile

Hope someone can help me...

Re: Xorg KMS - Resolution Problem on EEE 1005P

I think you missed this
http://www.archlinux.org/news/484/

xf86-video-intel only supports KMS now

With the move of xf86-video-intel 2.10.0 to extra, support for UMS has been removed from the intel driver. This means that KMS is a requirement now.

BTW, I downgraded to 2.9.1 because after a while (2-3 hours) the graphic performance goes down.

thx, gborzi ... this explains the error when i try to boot without kms big_smile (should visit the main page more often roll - only got bookmarks for wiki. bbs. and aur. wink )

so there's only the question how to enable 800x600...
