I have installed Slackware 12.1 on a Lenovo R61.

Everything works perfectly (middle mouse button, I've got my firewall up and running etc. etc.) apart from the screen resolution which is set to 1024x768. I would prefer 1280x800.

My graphics card is:

Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller

I have tried various propsed solutions I found via google searches. I have the patched 915resolution from the Gentoo site and I have tried editing xorg.conf. 915resolution runs before I startx.

915resolutions -l says it has changed the resolution:

Mode 5c : 1280x800, 24 bits/pixel

I cannot find, or think of, anything else to try. Does anyone have any similar experiences and has managed to find a solution? Or have I missed something obvious?

Below is the section from my xorg.conf.

Section "Monitor"

A quick googlin' lead me to various xorg.conf with the i810 xorg driver
So maybe try replace: Driver "intel" with: Driver "i810" in Device section
Lol I like that, if the middle mouse button works, all is well

I tried that but it made no difference. I don't think it's the driver as direct rendering is working. It's just the annoying 1024x768 resolution.

No error about screen resolution in /var/log/Xorg.0.log ?

Also maybe try to comment this line: Option "ForceBios" "1920x1440=1280x800"
in "Monitor" section (My Monitor identifier)
I don't see the ForceBios option in Monitor section of " man xorg.conf ", I think it is a wrong monitor option
Maybe try to use: Option "PreferredMode" "1280x800"
(in Monitor section, My Monitor)

I have an intel chipset on my desktop that will not render 1440x900 with the stock slackware xorg.conf.
(it could, I just can't get the options right)

The only way I've been able to get 1440x900 is by running xorgsetup as root. I don't have the same graphics chip as you, but I use the i915 and drm modules. It might be worth a try. I'm using slackware 12.1. I don't use the 915 resolution patch. This worked for me with the generic and huge kernels 2.6.24.5.

My card:

VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)

lsmod | grep i915:

i915 29056 2
drm 69672 3 i915


HTH

This is just a guess (and not a good one at that), but try searching these forums for Modeline (you'll probably find some posts by me). I don't feel like looking them up right now, but you may wish to try a custom Modeline for your monitor (this is often necessary, at least on PCs without an nVidia card [ie without the proprietary nVidia drivers], to achieve the higher resolutions).

OK, I was nice and did a quick search of the forums (for "Modeline"). See this threead. There are tons of other threads (often with posts by me) describing essentially the same thing, so if you can't get it working using the linked thread, do a little more searching.

Thanks for the info. I will experiment with this and post my results asap.

I've been through the various posts and tried the suggestions. The odd thing is it doesn't make any difference - doesn't even break anything. It's almost like the xorg.conf is being ignored.

Maybe you could find something interesting in X log?
