MasterMace Wrote:I'm really new to this, especially Linux. I've tried to edit my xorg.conf, according to this and other manuals, but when I restart my Asrock ION 330 HT, I get a glimpse of XBMC Live starting, but after that, I go back to a prompt, asking to log into XBMC Live. As soon as I put back my original xorg.conf, everything is fine again....

My adjusted xorg.conf:

I got the modelines from the internet, as in the output of xlog.txt, all relevant modes were rejected:

Code:

etc.

Anyone an idea of what I've done wrong / missed?

idlehands Wrote:I'm getting closer to figuring this out, however I'm a little confused. Is the process to tweak xorg.conf to get a correct value, that then will show up in the xbmc settings? I am pretty sure I set a mode for 720p in xorg, however when i recycle everything and check in xbmc to see if the mode shows up, its not there.

I created the mode from a gtf for 720p @60hz I'm also guessing at HorizSync and VertRefresh based on a "training manual" i found for my tv thta said 720p was 45khertz and vert was 60hz

thanks!

idlehands Wrote:ahh, that did it thanks!
also had to change

Code:

Option "ModeValidation" "NoEdidModes"

to

Code:

Option "ModeValidation"

I'm using the shotgun method it seems.

Although now xbmc menus look all flickery, but 720p content looks fine. well, subs and overscanned all to hell, but I think I can fix that with the xbmc video calibration. Fun fun!

gekados Wrote:My menus look flickery when i'm using 24hz in the menus, 60hz looks very smooth. I use the settings to match refresh to video instead and run 60hz as default.

idlehands Wrote:Oh boy.I was just hoping to set everything at 720p@60 and forget about it.
Are you saying that the menus default to 24hz or can be set independently of the video?
