Hello

This is not KnoppMyth related. I'm actually using Ubuntu for this frontend since I was not able to get X to load at all with KnoppMyth on this system (an intel mac mini). But I'm hoping that someone on these forums may have some insight.


I'm trying to output at a higher resolution on my frontend which is using the i810 drivers. My DFP is connected via DVI. I've used 915resolution o set the resolution I want to use (1920x540, although I know my display upports 1920x1080) but Xorg still drops me back down to 640x480.

In my Xorg.0.log, I see:

(II) VESA(0): h_active: 1920 h_sync: 2008 h_sync_end 2052
h_blank_end 2200 h_border: 0
(II) VESA(0): v_active: 540 v_sync: 542 v_sync_end 547 v_blanking:
562 v_border: 0
(II) VESA(0): Ranges: V min: 48 V max: 67 Hz, H min: 30 H max: 34
kHz, PixClock max 80 MHz
(II) VESA(0): Monitor name: RCA Scenium
(II) VESA(0): Searching for matching VESA mode(s):



So I set the resolution with:
sudo 915resolution 5c 1920 540

I restart xorg, and I see this in the X logs:
(II) VESA(0): Not using mode "1920x1080" (no mode of this name)

(II) VESA(0): Attempting to use 60Hz refresh for mode "640x480" (111)




Does anyone have any suggestions?

Check the names in the modeline section of your X config file match the names used in your Screens section.

Hi,

I would think that if you have an i810 video then your xorg.conf Driver should be i810. The vesa is a generic which gets you going at least in a basic mode so you can work on doing the setups.

I'm using the i810 driver. I've created modelines, but it always says this mode is not availble. I've used 915resolution to modify a mode in the video bios and edited /etc/default/915resolution to use the modified mode as the default resolution. Still nothing.

According to the xorg faq, i810 will only use modes supported by the video bios. I believe, however, that my problem is releated to using dvi. I've read on the mythtv-users mailing list that others have had the same problem using dvi->hdmi, but switching to vga out fixed their problem.

While true, I can use vga out to a crt and use any resolution i wish, this is not the case when it is connected to my tv via dvi.
