Default 8174 + xorg: can't get native resolution on laptop LCD

After installing the 8174 drivers, I've started experiencing a resolution problem that I didn't have with 7676 and 7667. My laptop LCD's native resolution of 1400x1050 @ 60hz appears as selected in gnome-display-properties, but the actual resolution I have seems to be 1280x1024 (or something close); everything seems stretched and blurry, plus the Gnome panel is invisible.

I see on the changelog that the new drivers resort to EDID frequencies by default, so I've added the option to ignore them to xorg.conf, but that didn't help either. I didn't need a modeline or any other adjustments with the older drivers.

Any help appreciated.

Please start X with the following command (once for 1.0-7676, and again for 1.0-8174):
startx -- -logverbose 5

and then post the resulting X log after you've done this for each driver version (for a total of 2).

Thanks,
Lonni

Thanks for your immediate attention; you can find the logs attached.

By the way, this is a PCI-E Geforce Go6200 chip, and I'm still having very bad 2D performance with it, even with the new drivers, so if you run into anything that may cause low 2D performance by hindering 2D acceleration or in some other way, please let me know as well.

Sorry, but you need to remove the IgnoreEDID option before starting X with the command I provided, otherwise I can't capture the EDID in your X log.

Thanks,
Lonni

Done, here they are again, this time with 7667 instead of 7676; there shouldn't be a difference since I didn't have this problem with either.

(Note: I noticed that I can see the Gnome panel when I switch to 1024x768 or anything lower.)

Thanks for the logs, they were just what I needed to see. This turns out to be the same issue as pre-existing bug 195559, which is currently being investigated by development.

Right now, I'm afraid that the only work-around is to downgrade to 1.0-7676.

Thanks,
Lonni

Thanks. Where can I learn more about this bug? Is it specific to the Go6200 and/or my version of xorg?

It has only been reported and reproduced with a Go6200. It is not specific to the version of X you are using.

Thanks,

I have the same problem with a go5200 32M.
I've tried to set the following resolution 1280*800@75, but I obtain 1024x768@60.

Xwang,
According to your bug report, 1280x800 is failing here:
Not using mode "1280x800" (vrefresh out of range)

Did 1.0-7676 work with the same xorg.conf at 1280x800?

Thanks,
Lonni

Yes, even if sometimes my note crashed after logout (but I think it was another problem).
By the way, since I'm a Suse user, I used sax to configure X and there isn't any 1280x800@60Hz here.
How can I manually fix it?

RESOLVED
I've manually modified /etc/X11/xorg.conf using the modeline I've obtain with the following command:
gtf 1280 800 60
Now I have the correct resolution.
Thank you.
