[i945] I945GM can't support acer X233H monitor 1920x1080 mode

[Devin]

Binary package hint: xserver-xorg-video-intel

I install ubuntu904(beta)-x86 on my laptop (Mobile 945GM/GMS/GME,943/940GML Express Integrated Graphics Controller),

and use acer X233H monitor(23inch) as second monitor. when I set monitor mode to standard mode(1920x1080x60Hz),the acer monitor screen messed.

buy I do same thing under windows-xp,the acer monitor work accurately.

I try to use xrandr set acer monitor like this:

MODENAME="1920x1080_63.00"
MODEPRAM="182.89 1920 2048 2256 2592 1080 1081 1084 1120 -HSync +Vsync"
xrandr --newmode $MODENAME $MODEPRAM
xrandr --addmode VGA $MODENAME
xrandr --output VGA --mode $MODENAME

then,the acer monitor work accurately.

but this is overfrequency for the acer monitor.

Just connected same monitor to my Ubuntu8.10 x86_64. Windowing looks ok, but movies won't play. youtube videos don't work, just show blank area in screen. When I open Screen Resolution, it says "unknown monitor".

I have a Sapphire ATI Radeon HD4830 video card in this system that I built a week ago. I previously had an old Princeton LCD monitor connected via DVI, and this problem did not occur until I connected the Acer and booted.

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:

  http://cdimages.ubuntu.com/releases/karmic/

If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as
well.

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

It seems likely to me this bug is gone; the -intel driver has improved immensely in Karmic and a lot of bugs are being reported as no longer present. So hopefully that's the case here too.

Bryce - this exact problem occurs on Macbook in Karmic (beta) with the X233H on the Nvidia 9400M - also doesn't connect to the projectors in Millbank in anything greater than 640x480. Same setup works for both on apples OS.

Tell me what data you need
