Want To Use Full LCD Panl Resolution: SuSE 10, Intel915 Video 1400x1050 on Dell D610
I am running SuSE10 on a Dell D610 with the Intel915 video card and a 1400x1050 lcd panel. Since the Intel915 doesn't correctly report its modes to SuSE SAX2 and the KDE desktop, it only runs at 1280x1024. SAXS says the display is 1400x1050 lcd. but kde only allows 1280x1024.
Therefore I use the 855resolution program (which comes in SuSE10 and works for the 915 graphics card), to reset one of the video modes to be 1400x1050 using the command '855resolution 3c 1400 1050' in one of my init.d scripts. This works, so when running my card now reports a valid 1400x1050 video mode when queried.
But in other (non-SuSE) linuxes people say I need to add a modeline to my X11/xorg.conf file to let KDE to know to run at full 1400x1050 resolution. In the SuSE xorg.conf file, there are no modelines, or it doesn't look like the ones quoted for other linuxes.
My desktop is still running only at 1280x1024, and KDE doesn't only gives 1280 as the highest I can go.
So for SuSE what is the next piece I need to do to get my full LCD panel to be used. Its a drag to have the black bars of unused screen all around.
Hi
I have an Acer TM660 and I have the same problem, as far as I have read this resolution is a virtual one that the 855 driver can not coupe with.
I looked for '855resolution' and found this site http://perso.wanadoo.fr/apoirier were you can download the source code and compile it on other distros, I'm going to try this myself.
As for modlines as far as I know they are used inform X of the display capabilities which in your and my case is not the issue because the lcd reports correctly it's maximum resolution, the bios from the graphic card is the one responsible for this problem as it those not respond with a 1400x1050 mode when queried.
And 855resolution gets the video bios to correctly report 1400x1050
Hi jdogpc,
In SuSE 10, it comes with 855resolution, that utility of A Poirier, and I have it in my init.d scripts, so that the Intel 915 video card properly reports it has a mode of 1400x1050. So that part is working. But in KDE, the desktop is still not allowed to go above a resolution of 1280x1024. And supposedly I think Its something to do with Xorg.conf and DRI. But the Xorg.conf in SuSE doesn't seem to have any modeline lines in it.
so I think I'm halfway but still not using my full LCD panel resolution.
check the SubSection "Display" to see if there a mode to "1400x1050" if not just add it, these are the resolutions X is allowed to work. if it can not work with the first it tries the second and so on, you also change X resolution by pressing the ctrl+'plus sign key' or ctrl+'minus sign key'.
I do have the /etc/X11/xorg.conf file there and it has section display with subsections saying 1400x1050. It actually has various of them.
And you'll see it is set for a Dell 1400x1050 LCD panel display. In the display it says use Modes(0)
It also says DRI and lists only one mode for that 0660. Don't know what this means, though.
So I'm still baffled. In kde, no desktop size above 1280x1024 is offered.
Thanks for you help on this.

While I don't have an intel chipset - because I am running Suse10 x86_64 on my Ferrari 3400 which has a 1400x1050 lcd. I have actually gotten the 3D drivers from ati to work and have a very similar xorg.conf as you. Therefore I would be interested to know what you get when you right-click on your 'desktop' -> Configure Desktop -> Display (button in left panel) for item two on the 'Size & Orientation' tab .... I have Screen Size at 1400x1050 and if I remember correctly I had to change it from 1024x768 by clicking on the 'drop-down' box.
Finally you should have an unselected 'check' box titled "Apply settings on KDE startup" .... if your changes here don't register upon restarting X then it may be worth your while to try checking this box before restarting X. If you don't know how to restart your x session let us know and we will share!
this is where my problem lies. My xorg.conf, says I can do 1400x1050, but in the Configure Desktop -> Display (button in left panel) for item two on the 'Size & Orientation' tab .... I have the Screen Size of 1280x1024 as my highest resolution in the drop down box. No choice for 1400x1050 appears there, and therefore I can't get my full screen size on the 1400X1050 lcd panel.
so how come it doesn't appear in KDE as an option, while the DRI seems active and the modes of 1400x1050 are permitted in the xorg.conf??
We're getting warmer with all your helps, but I'm still baffled.
thanks
I don't know just now how to unconfigure KDE wizards, but try create a new user start a new graphical session to see if it loads with 1400x1050.
If configure the resolution inside KDE it take relevance over "xorg.conf" file.
Hi jdogpc,
i tried you suggestion of logging in as a new user, but even there, the highest resolution in the kde desktop configuration is still 1280x1024.
So even though I have 855resolution run at each boot in an init script, and the Intel915 graphics adapter thereby reports a 1400x1050 resolution mode, which would use my full LCD panel screen size. and even though the X.org config file lists the 1400x1050 resolutions as I show above. I still can't use my full screen.
any other ideas? any one have some thoughts?

I have the Dell 2005fpw and in my xorg.conf I have the following:
Section "Modes"
Identifier "16:10"
Modeline "1680x1050" 146.2 1680 1960 2136 2240 1050 1080 1086 1089 -hsync +vsync
EndSection
I notice that you don't have any modeline in your modes section. I'm not sure what the setting would be for your monitor though.
Hi Seagull,
my question to you is, are you running SuSE 10.0 or a different linux distribution? Most distributions have modelines like yours, but SuSE, I believe, does not use them in the Xorg.conf file. thats why in the file I listed above there are no modelines at all.
I could be wrong about this, but I think the modelines are hidden somplace else in SuSE.

I'm running SuSE 10.0 Just upgraded the PC here at work from SuSE 9.1
There are 3 PCs here, all with the same monitor and all using SuSE. We all used the same xorg.conf details for the monitor. The only PC that had problems was the one running windows and that was down to the video card not supporting the resolution.
As for the modelines entry - my take is that if it's working leave it in.;-)
