Kodi Community Forum - [MOVED] Problems starting XBMC fullscreen

Pages: 1 2 3 4 5 6 7 8 9 10

The options are important too. The modelines, well tbh i cheated and just downloaded some - they likely do not produce pixel-perfect images but i dont care.

My scaler can give me the information needed to write the modelines, by adjusting suitable test-images until everything is perfect, a process known as calibration, for which people pay alot of money.

The xorg.conf options look mostely the same as mine - except for the modeline stuff. I'll have a look after this. Meanwhile some lines from Xorg.0.log:

As you can see, the driver even complains about incompatible edid information on the tv set. i think this perfectly fits the issue everybody's seeing.

Hehe - seems like it is as easy as this:

Code:
haggy@aereogramme /var/tmp $ gtf 1920 1080 50

  # 1920x1080 @ 50.00 Hz (GTF) hsync: 55.60 kHz; pclk: 141.45 MHz

or to try this at home:

Code:
gtf <horizontal_res> <vertical_res> <refresh_rate>

Learn something everyday! Thanks Smile

In nearly ten years of linux i NEVER stumbled upon this handy tool...
Would you mind posting some Xorg.log lines from your nvidia 8200 machine as this also seems to make a difference. Most of the issues seem to come from 8200/8300 GPUs.

Thanks for the tips - how do you launch XBMC? I am currently using my .xsession to do it AND am running --standalone. I think that this is not appropriate for using modelines right? How do you autostart XBMC at boot time?

Thanks,
xnappo

xnappo,

i'm unsure whether it will work in the way you describe or not. I simply add an entry to System/Prefs/Sessions

Up to now i start via inittab and xinitrc:

/etc/inittab:

Code:
x:5:once:/bin/su haggy -l -c "/bin/bash --login -c startx >/dev/null 2>&1"

and .xinitrc:

Code:
exec nvidia-settings --load-config-only &

exec ck-launch-session xbmc -fs --standalone

but i think i have to change this using modelines - at least --standalone has to go i think.

Unfortunately i dont think gtf is reliable - its given me the exact same modeline for both my Sony monitor and 42" TV.

Better than nothing though, but I suspect it wont give proper 1:1 pixel mapping and whatnot.

This is from my 8200...

So your xbmc command is simply 'xbmc.bin'. I am using '/usr/share/xbmc/xbmc.bin -q --standalone' . I don't have Gnome or anything installed - just using the minimum install - so I think in that case to match your setup I need to change my .xsession to start X, and then launch xbmc without --standalone..?

Thanks,
xnappo

what does '-q' mean?

Haggy Wrote:what does '-q' mean?

I have no idea, I just followed this guide:
http://wiki.xbmc.org/?title=HOW-TO:_Inst...ep-by-step

I also noticed this line in motd2k's .xorg:
Option "ModeValidation" "DFP-0: NoMaxSizeCheck, NoHorizSyncCheck, NoVertRefreshCheck, AllowNon60HzDFPModes, NoMaxPClkCheck, NoVesaModes, NoXServerModes, NoPredefinedModes"

I think that might be important.

I don't think gtf takes the actual screen into count as it is simply a nicer interface to a calculator :-)

every screen should handle those computed modelines well or am i wrong?
