Hi All,

I'm new to Linux and just picked up an Acer Revo to plug into my Samsung Plasma. Prior to this I've been running a Windows build of XBMC on this TV at 1920x1080 with zero problems, but wasn't able to play anything more complex than 720p H264 files...hence the Revo arriving.

I configured the Revo at a friend's using his TV and everything worked from a video perspective "out of the box" (that is - there was an option to run 1920x1080, and the resolution behaved as expected).

I brought it home last night and plugged it into my Samsung PN42A450 (http://www.samsung.com/us/consumer/tv-vi...l&tab=spec) and it is defaulting to the display's native resolution of 1024x768. Needless to say, when I play movies the aspect ratios are now all messed up.

I've tried playing around with my xorg.conf a little, but I'm a bit of a newb at this stuff. I tried putting in Mode "1920x1080", etc. and no matter what, when I boot up it still only lets me go as high as 1024x768@50hz.

Here's what my xorg.conf looks like right now:

And here's my xorg log:
http://pastebin.com/m1feb206e

As you can see it is spitting out a couple of interesting items:

"No modes were requested; the default mode "nvidia-auto-select" will be used as the requested mode."

and

"Virtual screen size determined to be 1024 x 768"

Any help to get me to have this run in 1920x1080 would be hugely appreciated.

Thanks.

Ok I booted into Windows on this machine and ran Powerstrip, here's what it came up with for a monitor driver and timings file:

TIMINGS





PowerStrip timing parameters:
1920x1080=1920,88,44,148,1080,4,5,36,148348,512

Generic timing details for 1920x1080:
HFP=88 HSW=44 HBP=148 kHz=67 VFP=4 VSW=5 VBP=36 Hz=60

VESA detailed timing:
PClk=148.35 H.Active=1920 H.Blank=280 H.Offset=72 HSW=44 V.Active=1080 V.Blank=45 V.Offset=4 VSW=5

Linux modeline parameters:
"1920x1080" 148.348 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync



Can anyone help me "put this all together" in the xorg.conf to make it work? Not sure why, but everytime I change the xorg.conf via Putty, the changes are lost when I reboot.

you need to add your modeline to section monitor

Section "Monitor"

Identifier "Monitor0"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 28.0 - 33.0
VertRefresh 43.0 - 72.0
Option "DPMS"
Modeline "1920x1080" 148.348 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync

EndSection

Thanks for the suggestion - I tried this after posting, (and also updated the VSync and HRefresh numbers to match). When I reload xbmc it just gives me a flashing screen.

I followed this how to:
http://forum.xbmc.org/showthread.php?tid...resolution

and it gave me another way of generating this xorg.conf, which made it look like this:


Same result - when I stop/restart xbmc I get a flashing screen.

Can someone tell me where I can put this xorg.conf file so that it gets
"remembered" by XBMC Live? If I make changes to the one at /etc/X11/, the changes are lost after I reboot. Is there a place I can put it on my USB drive so it will be used over the standard?

Thanks.

Ok - figured this out. The HOW-TO method didn't work for me, but as it turns out, the powerstrip settings were the key to getting me going. The main issue was a type on "Mode" (should have been "Modes") which I tracked down in the log file.

Here's my working xorg.conf



The only issues that remain for me (any help is appreciated):

1) The xorg.conf located in /etc/X11/ reverts to the vanilla state when I reboot (and subsequently goes into 1024x768). I can't get the changes to persist after a reboot - surely there is a way to fix this?

2) DTS stopped working. All other formats (AC3, etc.) work fine.

Thanks
