Unable to set 1440x900 resolution with i865g graphics chip

[Mikey Cooper]

Binary package hint: 915resolution

I have a PC with a built in i865g chipset (Bios Type 2 according to 915resolution) and am running Ubuntu 6.06. I recently hooked up a widescreen LCD to it and am unable to get 1440x900 resolution working. I have tried using 915resolution 0.5.2 to no avail.

If I follow the instructions and override mode 58 (1280x1024) to 1440x900, when I start up X, the monitor runs at 1280x1024@60.5 and the Gnome desktop attempts to renders at 1440x900, making the left portion of it render off screen.

If I set mode 54 instead and start X, the monitor tells me a "No signal detected". My driver is set to i810 in xorg.config and the only mode I have specified is "1440x900".

I'm attaching two Xorg.0.log files from the start ups of each mode. For now, I'm stuck at the default 1280x1024 scaled across the screen by the monitor. If there's any other information I can provide, please let me know.

This is the xorg log from starting X after overriding mode 58 to 1440x900.

This is the xorg log from starting X after overriding mode 54 to 1440x900. Using mode 54 causes the monitor to just say "No signal detected" once X tries to start. The startup song does play, so it's still starting X okay, just no video.

i915resolution resets the resolution information, but not the timing information. As a result, external displays are unlikely to work well.

Am I using the wrong tool for the job or is there just no way to support widescreen resolution on external displays with an i865g chipset?

Fwiw, I tested with the Feisty Hurd 1 LiveCD and it still displays in standard 1280x1024 resolution.

Mikey,

You could use the i810 modesetting driver. See Bug #86258.

Do you still have this issue with the latest release of Ubuntu ?

[Mikey Cooper (mikey-bluey)]

I no longer have this PC to test with.

Ok, thank you for your fast anwser. I'm closing this, feel free to reopen.

I've just purchased a 1440x900 monitor and I'm also having trouble getting that screen resolution. I'm running kubuntu 7.04.

1680x1050 external won't work.
