Good morning,

I dual boot into Ubuntu and Windows. I use windows for playback because I can use powerstrip for 48 Hz output to my projector and ffdshow for upscaling and sharpening. I use Ubuntu purely for vobcopy - the best!

I'd LOVE to drop windows completely, but I'd miss powerstip's ability to set custom timings.

Is there anything that can do this in the linux world?

I'm using a Radeon 9600XT video card, unfortunately, so this is probably going to be an uphill battle.

sounds like exactly what xorg.conf modelines are for. In fact, I seem to recall hearing that powerstrip can dump an output configuration as a modeline.

Unfortunately, I'm not skilled enough to explain how to set your xorg.conf file to use that specific mode instead of some other mode that gets autodetected; all I can suggest for that is man and google =/ Good luck.

Custom timings can be done via modelines in the xorg.conf file. You can use xvidtune to help tweak the modelines.

Do you mind walking through how you're ripping your DVDs with Ubuntu?

I'm not sure of the legality of posting dvd ripping how-to's. Google "vobcopy".

Yeah, a custom modeline looks like what I need. I'm rebuilding by HTPC tonight (new MB, CPU and hard drive). It may take me a while to get up and running, but I'll work on the modeline for 1280x720 @ 48 Hz and post my results.

It seems like there should be a modelines sticky in these linux forums, eh?

I'd totally be up for that!!! I spent HOURS this weekend trying to get 1080p on a friend's NuVision NVX37HDU2 LCD TV. We never did get it working. Via DVI to HDMI we could only get 800x600 max resolution. With VGA we could get some odd 1450 x something or other.

I'd say not only modelines but any other xorg.conf settings that needed to be included.

The gtf command line utility is a great asset. It generates modelines at any resolution and refresh rate based on the VESA General Timing Formula. You may need to make minor tweaks, as video cards sometimes have limitations on the resolution of their dot clock settings.

Before rebuilding my PC I used powerstrip to export the modeline I was using for 1280x720, 48Hz in Windows with the HD70. Here is the output:

PowerStrip timing parameters:
1280x720=1280,112,40,216,720,5,5,20,59329,2304

Generic timing details for 1280x720:
HFP=112 HSW=40 HBP=216 kHz=36 VFP=5 VSW=5 VBP=20 Hz=48

VESA detailed timing:
PClk=59.33 H.Active=1280 H.Blank=368 H.Offset=96 HSW=40 V.Active=720 V.Blank=30 V.Offset=5 VSW=5

Linux modeline parameters:
"1280x720" 59.329 1280 1392 1432 1648 720 725 730 750 +hsync +vsync


I haven't had time to set this up within Ubuntu yet. I'm struggling with wireless (AGAIN!). Wish I could remember how I got this working years ago...

What kind of problems are you having with your wireless?

It usually comes down to getting the correct driver module loaded for your wireless chipset. Type in "lspci" to see a list of cards and chipsets on your computer.

What kind of problems are you having with your wireless?
It's really just remembering all the details. Linksys WMP54G - but which chip?
Oh yeah, Ralink RT2500. So on and so forth we go...
I'll get it sooner or later.

Aside: Franklin, WI? I live in Bay View and work in Oak Creek. Small world!

Later,

For your card, I guess that you can use NDISWrapper or the Linux driver that is being developed here:
